Preparing for the AZ-305 certification exam begins with understanding the responsibilities of an Azure Solutions Architect. This role involves making architectural decisions across complex cloud systems, ensuring scalability, reliability, and cost-efficiency. The architect is expected to align business needs with cloud-based infrastructure, striking a balance between performance and budget.
The exam does not test isolated facts. Instead, it challenges your ability to design systems that are resilient, secure, performant, and operationally efficient. Azure Solutions Architects are often the bridge between technical execution and strategic planning. They collaborate with stakeholders, developers, and IT professionals to deliver cloud architectures that solve business challenges.
Familiarizing With The Core Exam Domains
The AZ-305 exam focuses on four key domains:
- Designing identity, governance, and monitoring solutions
- Designing data storage solutions
- Designing business continuity solutions
- Designing infrastructure solutions
Each of these domains contributes to the broader capability to plan and deploy enterprise-grade architectures on Azure. It is not enough to understand what each service does. You must also know how to select between them under specific design constraints. For instance, knowing when to use Azure Key Vault versus managed identities, or when to choose between different storage replication options, reflects the depth of insight required.
Studying domain by domain allows for a structured approach, but always return to integration. Microsoft emphasizes holistic design thinking, where services are not implemented in silos but connected across compliance, performance, cost, and scalability.
The Strategic Importance Of Identity And Governance
Designing identity and governance solutions is more than setting up users and roles. The exam expects proficiency in integrating Active Directory with Azure AD, configuring conditional access, and using identity protection to limit threats. However, governance expands into controlling access at scale across resources using Azure Policy, Management Groups, and RBAC.
You should understand how governance models evolve over time and how to implement scalable solutions that do not require constant human intervention. Creating guardrails using policies or Blueprints is vital in large organizations with multiple subscriptions and teams.
The challenge is often in navigating gray areas, like when security and productivity conflict. The architect must craft solutions that maintain user autonomy while preserving regulatory compliance.
Designing Resilient Data Storage Solutions
Data architecture forms a cornerstone of cloud systems. Azure provides several options, including Blob Storage, Data Lake, Cosmos DB, Azure SQL, and Synapse Analytics. Selecting the right service depends on factors such as latency, volume, transaction consistency, and disaster recovery needs.
The AZ-305 exam evaluates your ability to weigh trade-offs. A common scenario might ask which storage strategy ensures both high performance and strong consistency across regions. Understanding replication types (LRS, ZRS, GRS, RA-GRS) and backup capabilities will help you make informed decisions.
You must also be capable of designing for both OLTP and OLAP workloads. The exam often integrates analytics into architecture, testing your ability to plan pipelines that accommodate ingestion, transformation, and long-term storage strategies.
Designing For Business Continuity And Disaster Recovery
Designing business continuity solutions is one of the most critical and nuanced areas of the AZ-305 exam. Architects must assess business impact, establish Recovery Point Objectives (RPO), and Recovery Time Objectives (RTO), and align those with Azure service capabilities.
Azure Site Recovery, Backup, and geo-redundant architectures come into play. But the exam goes deeper, probing your ability to implement these technologies within budget and without disrupting operations.
Disaster recovery is not only about data recovery but ensuring service continuity. This requires planning for database failover, load balancing, and resilient networking. You may be tested on cross-region failover strategies or hybrid scenarios where on-premises data must remain accessible in case of Azure region failures.
Designing Robust Infrastructure Solutions
Infrastructure decisions in Azure involve more than choosing the right VM sizes. You must evaluate the use of IaaS versus PaaS, understand networking patterns, and implement scalable architecture using tools such as Azure Load Balancer, Application Gateway, or Azure Front Door.
Virtual Network design, NSG configurations, and hybrid network integration are key. You may need to plan a secure communication channel between on-premises infrastructure and Azure using VPN or ExpressRoute, while also considering performance and cost.
Architects must address redundancy at multiple levels—compute, networking, and storage. Each component has to align with performance expectations and future growth. Infrastructure design often intersects with application modernization, containerization, and serverless computing.
Integrating Monitoring And Observability Into Architecture
Effective solutions include not just design and deployment, but also monitoring, alerting, and performance diagnostics. Azure Monitor, Log Analytics, and Application Insights are core tools.
You should be able to design centralized monitoring architectures, using diagnostic settings, log retention policies, and custom dashboards. This allows stakeholders to track SLAs, identify trends, and receive alerts on abnormal behavior.
Observability also feeds into governance and security. For example, you may need to implement real-time alerting on unauthorized access or unexpected cost spikes. Integration with tools like Azure Sentinel or third-party SIEM solutions can help extend your design into security analytics.
Real-World Scenarios: The Exam’s Core Approach
The AZ-305 exam is scenario-heavy. You will encounter case studies that provide customer requirements, limitations, and expectations. Your job is to select the most fitting architectural decision based on given parameters.
These scenarios mimic real-life enterprise challenges. For example, designing a multi-region solution for a retail platform that must maintain sub-second latency and comply with data residency laws. Or configuring a resilient solution for a healthcare provider needing high availability and encryption for sensitive records.
This approach ensures that the architect is not just a technician but also a business enabler, capable of understanding and solving challenges within organizational boundaries.
Developing The Right Mindset For AZ-305 Success
Passing this exam requires more than consuming documentation or using lab environments. It requires cultivating the mindset of a cloud architect—someone who considers scalability, security, compliance, and cost in every decision.
You must understand why certain trade-offs are acceptable under specific business conditions. Some solutions may offer technical elegance but exceed cost targets. Others may provide cost savings but introduce operational risk.
Practicing architectural thinking will not only prepare you for the AZ-305 exam but also prepare you for real-world design roles where such decisions have long-term consequences.
Preparing Strategically With Hands-On Experience
Experience with Azure tools and real deployments is essential. It is recommended to simulate complete architectures, including VNet peering, storage redundancy, backup configurations, and identity federation.
You can build a test environment that mimics an enterprise-grade architecture. Try connecting virtual networks across regions, deploy scalable APIs behind gateways, and enforce policies using Azure Governance tools.
Documentation and practice exams have their place, but Azure’s complexity demands experiential learning. Working through architectural challenges yourself helps solidify decision-making skills far more effectively than passive reading.
Balancing Performance, Cost, And Scalability In Azure Architecture
Architectural decisions in cloud environments are rarely binary. A central theme in the AZ-305 exam is balancing trade-offs among performance, cost, and scalability. Candidates are expected to understand how to fine-tune cloud resources to match current workloads while preparing for future demand.
Designing for scalability is not only about horizontal and vertical scaling. It also includes configuring autoscaling, provisioning burstable resources, and architecting stateless applications. Azure App Service Plans, Virtual Machine Scale Sets, and Azure Kubernetes Service provide different scaling strategies based on workload patterns.
Managing cost involves choosing the right pricing tier, implementing budget policies, and using reserved instances where applicable. Candidates must identify areas where cost optimization is feasible without compromising user experience. Performance should always meet SLAs, but not at the expense of budgetary constraints.
In the exam, you may be given usage patterns, peak traffic statistics, or business forecasts. You will need to recommend infrastructure and services that provide performance guarantees while staying within financial guidelines.
Selecting Appropriate Compute Services
The AZ-305 exam challenges candidates to differentiate among compute services and apply the best solution depending on context. A task might involve choosing between VMs, App Services, Containers, or Serverless Functions.
Each compute model has its use case. Virtual Machines offer control and compatibility but require maintenance and scaling management. App Services work well for traditional web applications with less overhead. Containers offer portability and rapid deployment, and Functions work best for event-driven workloads that don’t require persistent infrastructure.
You must be able to evaluate deployment models (single instance vs. scalable group), integrate compute with networking, and manage availability. Availability Zones, paired regions, and proximity placement groups are essential tools to meet uptime and latency objectives.
For example, deploying a solution across Availability Zones ensures resilience, but the implications for networking and inter-zone data transfer costs must also be considered.
Designing A Secure Networking Strategy
A strong understanding of Azure networking is fundamental to passing the AZ-305 exam. The ability to design secure, performant, and scalable networks directly impacts service reliability and data protection.
Network architecture spans more than just configuring VNets and subnets. It includes Network Security Groups, Application Security Groups, firewalls, routing, and hybrid connectivity solutions. Designing hub-and-spoke topologies for central control and using ExpressRoute for dedicated connectivity are common practices.
You will also encounter scenarios that require VPN failover, custom DNS configurations, or private endpoints to restrict public exposure. The exam tests your knowledge of isolating workloads, securing ingress and egress, and ensuring compliance through proper segmentation.
A robust design limits lateral movement and introduces minimal administrative friction. Often, you’ll need to recommend a solution that meets compliance requirements without obstructing user access or application performance.
Optimizing Identity Solutions With Conditional Access And Multi-Factor Authentication
Azure identity solutions revolve around Azure Active Directory. A candidate must understand how to implement secure access using Conditional Access policies, identity governance, and authentication methods.
The exam includes scenarios where users access services across different devices, geographies, or risk profiles. You may be asked how to configure multi-factor authentication dynamically using risk levels or device compliance. Conditional Access allows enforcement of specific behaviors, like requiring MFA for sign-ins from untrusted networks or blocking legacy protocols.
Designing identity solutions extends to hybrid environments. You must know how to connect on-premises Active Directory with Azure AD using tools like Azure AD Connect or Cloud Sync. These configurations impact latency, synchronization intervals, and resiliency.
Additionally, you must plan for guest access in B2B collaboration or identity federation for external organizations, ensuring minimal data exposure while enabling productivity.
Structuring Effective Role-Based Access Control
Role-Based Access Control (RBAC) enables fine-grained permissions in Azure. The AZ-305 exam evaluates your ability to assign roles according to the principle of least privilege.
The objective is to provide access only where needed, avoiding over-privileging users or services. For instance, a storage administrator may need access to manage containers but not view financial data stored within.
Effective RBAC design involves creating custom roles when built-in roles are too broad, managing inheritance across resource groups, and auditing assignments over time. Azure Blueprints and Management Groups help enforce consistent policies and access across subscriptions.
The exam tests your ability to recommend RBAC strategies in contexts where organizations operate in complex, multi-tenant or segmented environments. Improper configurations can expose systems to risk or create bottlenecks in development and deployment pipelines.
Designing Monitoring And Logging For Complex Systems
Monitoring is integral to cloud architecture, and the AZ-305 exam includes significant focus on observability design. You must recommend solutions that detect anomalies, provide insight, and automate alerts.
Azure Monitor, Log Analytics, and Application Insights offer comprehensive telemetry across infrastructure, applications, and user behavior. Understanding how to centralize logs, configure retention, and design dashboards enables proactive troubleshooting and system optimization.
You’ll be tested on setting up alerts for CPU thresholds, memory consumption, application performance, and user sign-in anomalies. Automated responses using Logic Apps or webhooks might be required to reduce response times.
Monitoring should be planned during the design phase, not post-deployment. This means integrating diagnostics at every level and ensuring stakeholders can access relevant insights.
Building For Compliance And Regulatory Requirements
The AZ-305 exam includes questions around designing for compliance with industry and regional regulations. This could include data residency, encryption standards, access logging, and audit capabilities.
Services like Azure Key Vault, Private Link, and Azure Policy are essential in enforcing compliance. You must know how to encrypt data at rest and in transit, manage keys, and isolate services using virtual networks or dedicated instances.
Additionally, governance frameworks like Azure Blueprints allow for repeatable deployments that embed compliance requirements. For example, automatically applying encryption settings, tagging policies, or resource naming conventions as part of every deployment.
Designing compliant solutions involves collaboration across legal, security, and IT teams. Your architecture must meet these expectations without delaying innovation or creating unnecessary complexity.
Designing Data Integration And Analytics Pipelines
Modern enterprises need data-driven insights, and Azure offers services for ingesting, storing, and analyzing large volumes of structured and unstructured data. The AZ-305 exam tests your ability to integrate these services into broader architectures.
Data Factory, Synapse Analytics, and Event Hubs serve different parts of the data pipeline. You must understand how to design ETL workflows, manage streaming ingestion, and connect disparate systems securely.
The exam may require you to choose between batch and real-time processing or decide how to manage long-term storage in a cost-effective way. Knowledge of lifecycle policies, data tiering, and access controls plays a significant role in designing analytics systems.
Successful candidates can build systems where insights flow automatically to business users without excessive manual effort or exposure to sensitive information.
Making Decisions With Architecture Diagrams And Requirements
In the AZ-305 exam, many scenarios are built around architecture diagrams and written requirements. Interpreting these correctly is critical. The exam is less about definitions and more about applying architectural judgment.
You may see a diagram with user flows, network zones, and data storage, along with business constraints like compliance, performance SLAs, or geographic reach. Your task is to select a set of services that satisfies all conditions with minimal compromise.
Sometimes multiple answers seem plausible. The best approach is to evaluate trade-offs explicitly. Understand which requirements are mandatory versus optional and eliminate solutions that fail on core constraints.
Architecture diagrams are not decorative; they contain critical clues about the design context, which services are already in use, and which integration points are at risk.
Working With Multi-Tier And Microservices Architectures
Designing for modern applications involves multi-tier or microservices-based models. The AZ-305 exam expects understanding of service boundaries, API gateways, and integration patterns like event-based messaging or queueing.
You should be comfortable designing APIs using Azure API Management, securing endpoints, and deploying backend services using AKS or App Services. Load balancing, session management, and traffic routing are key.
Microservices introduce operational complexity. The architect must ensure that logging, telemetry, failover, and dependency management are addressed from the outset. Azure Service Bus, Event Grid, and Logic Apps enable communication between services while preserving decoupling.
Real-world cases in the exam may ask how to migrate a monolith to microservices or support global users with APIs hosted across multiple regions.
Optimizing Performance And Scalability In Azure Architectures
Designing high-performing, scalable solutions is a fundamental responsibility of an Azure Solutions Architect. The AZ-305 exam expects candidates to demonstrate mastery in choosing the right services and configurations to optimize performance while allowing room for growth. Scalability is not just about handling more users or data; it also involves ensuring consistent user experience and application responsiveness under dynamic workloads.
Scalable systems are typically built on cloud-native services that support elasticity. Virtual Machine Scale Sets, App Services with auto-scaling, and Azure Kubernetes Service are just a few examples. However, the challenge lies in selecting the most suitable tool based on workload characteristics, such as stateless vs. stateful, short-lived vs. long-running, and real-time vs. batch processing.
Understanding load balancing is another crucial aspect. Azure provides multiple load balancing solutions, such as Azure Load Balancer, Application Gateway, and Azure Front Door. Choosing among them depends on whether your priority is layer 4 or layer 7 traffic routing, global vs. regional availability, or SSL termination support.
Managing Costs Without Compromising Architecture Quality
A highly optimized Azure architecture should not only deliver performance but also control costs. This aspect is a major focus in the AZ-305 exam. Architects must understand pricing models, such as pay-as-you-go versus reserved instances, and design with cost governance in mind.
Azure Cost Management tools can track resource consumption and project monthly expenses. However, the real test lies in making cost-effective choices from the start. For example, choosing B-series VMs for development environments can significantly reduce costs. Likewise, tiered storage strategies using hot, cool, or archive access tiers can manage storage expenses intelligently.
Another strategy is using serverless computing, which charges only for actual usage. Azure Functions and Logic Apps are suitable for infrequent tasks or workloads that scale horizontally. Architects must identify these opportunities and balance performance needs with financial constraints.
Securing Azure Environments Through Architectural Best Practices
Security is a foundational pillar of every Azure solution, and the AZ-305 exam reflects this by integrating security design decisions across all domains. You will not be asked isolated questions about specific settings. Instead, expect scenario-based prompts that challenge your ability to integrate secure-by-design principles throughout the architecture.
The use of Azure AD for authentication and authorization is a common thread. However, secure design goes beyond identity. Data protection, secure communication, role-based access, encryption, and threat detection must all be addressed.
Designers should implement network segmentation using Network Security Groups, private endpoints, and Application Security Groups. Also, using Azure Key Vault for securing secrets, certificates, and encryption keys is essential. Architecture decisions around service-to-service authentication using managed identities reflect a deeper understanding of security integration.
Zero Trust architecture principles are increasingly reflected in exam questions. These include never assuming trust, verifying explicitly, and implementing least privilege. Knowing how to enforce these through Conditional Access, Just-In-Time VM access, and Identity Protection policies is important.
Addressing Compliance And Regulatory Requirements In Design
Many cloud solutions operate under strict regulatory or industry-specific requirements. These include GDPR, HIPAA, ISO 27001, and more. The AZ-305 exam may include scenarios requiring compliance alignment without compromising usability or availability.
Data residency, retention policies, encryption standards, and access logging are all design factors. For example, you might be asked how to architect a solution that ensures personal data never leaves a particular Azure region. This might involve using region-specific resources and disabling geo-replication.
Also, maintaining audit trails is essential. Azure provides services like Microsoft Defender for Cloud and Azure Monitor to support compliance reporting. However, the architect must decide when and how these tools are integrated into the overall solution.
Architects must design for security with compliance in mind but without degrading user experience or inflating costs. Balancing these competing priorities is often the difference between a pass and a fail on the exam.
Implementing High Availability And Resilience
Availability and resilience are often confused but serve different purposes. High availability ensures uptime during normal failures, such as hardware or network issues, while resilience includes the ability to recover from rare but severe disruptions like region-wide outages.
The AZ-305 exam evaluates your ability to design systems with redundancy across compute, storage, and networking. This includes using Availability Zones, Availability Sets, and configuring load balancing across multiple regions.
Designing for failure requires anticipating weak points. For instance, an application deployed in a single zone is vulnerable to zone failure. Architects must know when to distribute components across zones and regions. Azure Traffic Manager and Azure Front Door can be used for global failover strategies.
Also, database resilience is important. Options include Active Geo-Replication for Azure SQL or multi-region writes for Cosmos DB. Your design choices must reflect business continuity plans, including acceptable RPOs and RTOs, which directly influence the architecture.
Designing For Operational Excellence
Operational excellence refers to the ability to monitor, manage, and improve systems over time. This is not often covered in basic Azure learning paths, but the AZ-305 exam assumes you understand how to create self-healing, well-instrumented systems.
This involves integrating observability tools like Azure Monitor, Log Analytics, and Application Insights. Knowing how to implement telemetry from the start can save time and money during operations. Alerts, dashboards, and action groups must be designed in such a way that teams can act on data in real-time.
Automating responses to issues is another part of operational design. For example, automating scale-out when CPU usage exceeds a threshold or auto-healing through Azure Functions can improve SLA compliance.
Also, operational excellence includes deployment practices. Designing CI/CD pipelines using tools like Azure DevOps or GitHub Actions allows for consistent, repeatable deployments. Infrastructure as Code using ARM templates or Bicep also contributes to operational maturity.
Architecting Hybrid And Multi-Cloud Solutions
Real-world cloud solutions are rarely isolated to one environment. Enterprises often operate hybrid or multi-cloud setups for reasons ranging from compliance to legacy constraints. The AZ-305 exam tests your ability to design with this complexity in mind.
For hybrid architectures, Azure services like Azure Arc, ExpressRoute, and VPN Gateway allow integration with on-premises systems. Azure Stack is another option for running Azure services in private data centers. Architects must understand how these tools affect security, latency, and cost.
Designing multi-cloud solutions often requires balancing vendor lock-in with cross-cloud compatibility. While the exam does not expect detailed knowledge of other cloud providers, it does test your ability to build modular architectures that can interface with external systems through APIs, secure endpoints, and distributed data solutions.
Networking becomes particularly important in hybrid designs. Routing, DNS resolution, name spaces, and firewalls must be carefully designed. Mistakes in these areas can lead to significant outages or security risks.
Building For Evolving Business Needs
Azure architecture should never be static. A solution that meets today’s business requirements may fail tomorrow. The AZ-305 exam often includes questions about how to build solutions that can evolve with business goals.
Designing for modularity, versioning, and extensibility is essential. For example, microservices architectures or API-first development allows for adding or modifying functionality without impacting the entire system.
Planning for future integrations, higher traffic, more users, or advanced analytics capabilities must be reflected in your architecture. Azure services like Event Grid, Logic Apps, and Data Factory support event-driven and scalable architectures that can adapt to change.
Governance must also evolve. Using tools like Azure Blueprints or Policy to enforce organization-wide rules ensures that future teams can deploy resources securely and consistently without starting from scratc
Developing Architectural Maturity Beyond The Exam
Studying for AZ-305 should be seen as part of a longer journey. Designing real-world Azure solutions involves navigating technical constraints, business expectations, and organizational dynamics. The exam reflects only part of the real responsibilities of an architect.
Therefore, after passing the exam, continue refining your architectural judgment. Engage in hands-on projects, contribute to design reviews, and learn from incidents. Architectural maturity is developed by solving real problems and reflecting on outcomes.
Reading design documents, post-mortems, and customer case studies can further enrich your perspective. While AZ-305 validates your design knowledge, true excellence comes from experience, iteration, and critical thinking .
Designing Application Architecture For Distributed Systems
Modern enterprise systems are no longer monolithic. Distributed architectures are becoming the default in cloud environments. The AZ-305 exam evaluates how well candidates can design scalable, modular, and reliable application architectures that embrace these principles.
Distributed systems often involve decoupling components using message queues, APIs, or event-driven patterns. Azure provides services like Azure Service Bus, Event Grid, and Event Hubs for such designs. Candidates must understand when to use these services, based on latency requirements, fault tolerance, and consistency.
Designers should consider the importance of idempotency, eventual consistency, and failure handling when building distributed applications. In a multi-tier application, each layer must degrade gracefully and handle transient faults using retry patterns and circuit breakers.
Communication between distributed components should be secure and reliable. Azure Private Link, API Management, and Virtual Network integration are vital for securing internal traffic. The exam expects candidates to balance isolation, latency, and cost.
Selecting Appropriate Storage Solutions Based On Requirements
Storage is a central decision in architecture design. The AZ-305 exam challenges architects to choose the right storage type based on access patterns, performance, durability, and cost.
Azure offers several storage options: Blob Storage for unstructured data, File Storage for shared access, Queue Storage for asynchronous processing, and Table Storage for NoSQL needs. More advanced scenarios include using Azure Data Lake for analytics and Azure Disk Storage for high-performance VM needs.
For transactional workloads, relational databases such as Azure SQL and open-source options like PostgreSQL are available. For high-throughput and global distribution, Cosmos DB offers a multi-model, multi-region architecture with tunable consistency.
Architects must also address backup, geo-replication, encryption at rest, and lifecycle policies. Questions in the exam may ask you to compare storage tiers or design a data archiving strategy that balances performance with regulatory requirements.
Designing Identity, Authentication, And Authorization Solutions
Identity is a cornerstone of secure architecture. The AZ-305 exam expects architects to build systems that integrate seamlessly with Azure Active Directory while providing robust access control.
Authentication involves verifying who the user or service is, while authorization ensures they can only perform permitted actions. Azure offers role-based access control, conditional access policies, managed identities, and hybrid identity options.
Designers must understand when to use Azure AD B2C, especially in scenarios involving external users or custom branding. For internal workforce identity, integrating on-premises Active Directory with Azure AD using Azure AD Connect is a common pattern.
Architecting a secure system includes minimizing privilege using the principle of least privilege, separating duties, and using just-in-time access. Multi-factor authentication, identity protection, and privileged identity management are also part of security best practices.
Scenarios in the exam may test your ability to design identity solutions for hybrid environments, multi-tenant apps, or regulated industries. Success requires not just product knowledge, but a strong grasp of identity management principles.
Implementing Governance And Policy Enforcement At Scale
As organizations scale, enforcing consistent governance becomes critical. The AZ-305 exam focuses on how architects use policies, tagging, management groups, and subscriptions to enforce standards across large environments.
Azure Policy allows enforcement of specific rules, such as restricting resource types or enforcing naming conventions. Azure Blueprints package policies, role assignments, and templates into reusable governance artifacts. Architects must know how to apply these at scale, across different business units.
Management groups provide a hierarchy for organizing subscriptions, enabling policy inheritance and centralized billing. Resource locks, custom roles, and cost tracking also help enforce governance while allowing flexibility.
The exam may present scenarios involving multiple teams, regions, or compliance boundaries. Your design must balance autonomy with control. For example, a decentralized team might need separate subscriptions, while security and policy enforcement remain centralized.
Governance decisions also influence operational efficiency. Well-designed policies can prevent misconfigurations and enforce security standards without introducing manual overhead.Planning Monitoring, Logging, And Alerting Strategies
Monitoring and observability are essential in modern architectures. The AZ-305 exam assesses how well architects plan for ongoing visibility into application performance, security, and infrastructure health.
Azure Monitor provides a unified platform for collecting metrics, logs, and telemetry. Log Analytics and Application Insights allow deep insights into both infrastructure and application behavior.
Effective architecture includes designing alerting thresholds, dashboards, and automated actions. Action Groups can notify teams via email, SMS, or trigger automation tools like Azure Logic Apps when thresholds are exceeded.
For example, alerting on unusual CPU spikes, slow response times, or failed login attempts provides early warning signs. Collecting diagnostic logs from storage accounts, key vaults, and databases also supports auditing and incident response.
Questions may ask how to monitor workloads in multi-region deployments, integrate third-party monitoring tools, or automate remediation. The right answer depends on balancing visibility, cost, and response time.
Designing Data Integration And Analytics Architectures
Data integration is not just about moving data; it is about designing pipelines that are efficient, scalable, and secure. The AZ-305 exam expects architects to integrate structured and unstructured data sources across on-premises and cloud systems.
Azure Data Factory is a core component for orchestrating data workflows. It supports both batch and real-time ingestion and integrates with most Azure services. In modern architectures, it often connects to Azure Synapse Analytics for analysis and reporting.
For streaming scenarios, Event Hubs and Stream Analytics process real-time data from sensors, logs, or IoT devices. The results can be stored in Azure Data Lake or pushed to dashboards for immediate action.
Data security is critical. Data in transit should use encryption, and at rest should be protected by managed keys or customer-managed keys. Role-based access and audit logging further enhance trust in the data pipeline.
The exam may pose scenarios involving IoT telemetry, operational dashboards, or machine learning pipelines. The key is selecting components that match volume, velocity, and transformation needs without introducing unnecessary complexity.
Addressing Application Migration And Modernization
Enterprises are constantly migrating legacy systems to the cloud. The AZ-305 exam covers design patterns for lift-and-shift, refactor, and rearchitect scenarios. Understanding the trade-offs between these approaches is crucial.
Lift-and-shift involves minimal changes and is ideal for quick cloud adoption. However, it may not offer the full benefits of cloud scalability or cost savings. Azure Migrate helps assess readiness and plan the migration path.
Refactoring includes modifying applications to run more efficiently in the cloud. This may involve moving to App Services, containers, or serverless functions. Architects must decide when the additional effort results in long-term gains.
Rearchitecting is the most invasive but enables microservices, CI/CD pipelines, and cloud-native development. The exam may include decisions on container orchestration using Azure Kubernetes Service or breaking a monolith into discrete APIs.
Success in migration scenarios involves planning for network topology, identity integration, data synchronization, and rollback strategies. Business continuity and downtime minimization must always be considered.
Managing Dependencies And Integration Points
Every system depends on other systems, whether internal services, external APIs, or databases. The AZ-305 exam evaluates how architects manage these dependencies to ensure performance, resilience, and maintainability.
Designing with contracts and schemas enables loose coupling. For example, using API Management to expose services creates an abstraction layer that shields internal services from changes. For internal components, service discovery and versioning are critical to managing change.
External dependencies should be treated as failure-prone. Timeouts, retries, and fallback mechanisms must be built into the architecture. Resilience testing and failure injection are becoming standard practices.
Security must be enforced even between trusted services. Using managed identities, private endpoints, and identity-based access ensures only authorized calls occur. Network isolation and firewall rules further protect internal services.
The exam may test your ability to integrate third-party payment systems, legacy SOAP APIs, or mobile backends. Managing data flow, rate limits, and service-level agreements is key.
Making Trade-Offs In Real-World Scenarios
Designing systems is rarely about perfect solutions. The AZ-305 exam places heavy emphasis on making informed trade-offs between performance, cost, complexity, and time-to-market.
For example, a fully redundant, multi-region architecture may offer excellent availability but at a significant cost. You may be asked whether that level of resilience is needed for an internal tool used once a day.
Similarly, a data warehouse may support both real-time analytics and batch processing. However, separating workloads could improve performance at the expense of simplicity.
Candidates must balance short-term constraints with long-term goals. Some scenarios may ask for minimum viable architectures that can be scaled over time. Others may require up-front investment for critical workloads.
Understanding trade-offs requires deep familiarity with Azure services, but also a strategic mindset. Good architecture is about aligning technical solutions with business needs while remaining adaptable.
