Question 820
A reviewer suggests AWS X-Ray when asked how to decouple systems with durable asynchronous message queues, although that offering is primarily used to trace distributed requests through supported application components. Which alternative is the more precise choice?
- Amazon SNS
- AWS X-Ray
- Amazon SQS
- Amazon MQ
Explanation
Correct Answer
C:Amazon SQS addresses the new need to decouple systems with durable asynchronous message queues because sQS holds messages for consumers to process independently; AWS X-Ray supports the different existing task to trace distributed requests through supported application components.
Incorrect Answers
A:Amazon SNS is intended to fan out notifications to multiple subscribed endpoints because sNS uses topics and subscriptions to publish messages to multiple destinations; in this design the new outcome is to decouple systems with durable asynchronous message queues, which calls for Amazon SQS rather than Amazon SNS or the earlier AWS X-Ray.
B:AWS X-Ray primarily supports the earlier need to trace distributed requests through supported application components because x-Ray provides distributed tracing to help find latency and failure sources, but the new task is to decouple systems with durable asynchronous message queues; that is why Amazon SQS is preferable here.
D:Amazon MQ is intended to migrate applications needing managed message brokers and standard protocols because Amazon MQ supports broker engines such as ActiveMQ or RabbitMQ; in this design the new outcome is to decouple systems with durable asynchronous message queues, which calls for Amazon SQS rather than Amazon MQ or the earlier AWS X-Ray.

Question 824
A team already uses Amazon Route 53 to resolve application domain names and apply supported DNS routing policies. It now must answer DNS requests with an endpoint selected for lower network latency, which is a separate requirement. What should it select for that new objective?
- Route 53 latency routing
- Amazon Route 53
- AWS Direct Connect
- Amazon VPC
Explanation
Correct Answer
A:Route 53 latency routing addresses the new need to answer DNS requests with an endpoint selected for lower network latency because latency-based policies choose among configured Region records using AWS latency observations; Amazon Route 53 supports the different existing task to resolve application domain names and apply supported DNS routing policies.
Incorrect Answers
B:Amazon Route 53 primarily supports the earlier need to resolve application domain names and apply supported DNS routing policies because Route 53 is a managed DNS and domain service with traffic-routing and health-check features, but the new task is to answer DNS requests with an endpoint selected for lower network latency; that is why Route 53 latency routing is preferable here.
C:AWS Direct Connect is intended to establish dedicated private network connectivity from a site to AWS because direct Connect provides a dedicated network connection through supported locations; in this design the new outcome is to answer DNS requests with an endpoint selected for lower network latency, which calls for Route 53 latency routing rather than AWS Direct Connect or the earlier Amazon Route 53.
D:Amazon VPC is intended to create a logically isolated IP network for AWS resources because a VPC defines virtual networking boundaries and hosts configurable subnets and routing; in this design the new outcome is to answer DNS requests with an endpoint selected for lower network latency, which calls for Route 53 latency routing rather than Amazon VPC or the earlier Amazon Route 53.
Question 825
The acceptance criteria for an AWS solution include the ability to run workloads on provider infrastructure without maintaining local servers. Which item should the team choose?
- AWS CodePipeline
- Public cloud deployment
- AWS Outposts
- Manual console provisioning
Explanation
Correct Answer
B:Public cloud deployment matches the goal to run workloads on provider infrastructure without maintaining local servers because a public cloud model uses infrastructure operated by an external cloud provider. It does not inherently preserve a local-only application dependency. Manual console provisioning is for the different objective to perform a one-off configuration with interactive review.
Incorrect Answers
A:AWS CodePipeline addresses the separate need to orchestrate source-to-deployment stages automatically because codePipeline coordinates supported actions across a delivery workflow; it is not as direct as Public cloud deployment for the actual requirement to run workloads on provider infrastructure without maintaining local servers.
C:AWS Outposts addresses the separate need to run AWS-managed infrastructure at a customer premises for local requirements because outposts extends selected AWS infrastructure and services to supported on-premises locations; it is not as direct as Public cloud deployment for the actual requirement to run workloads on provider infrastructure without maintaining local servers.
D:Manual console provisioning addresses the separate need to perform a one-off configuration with interactive review because the console suits an infrequent human-guided operation when repetition is not the priority; it is not as direct as Public cloud deployment for the actual requirement to run workloads on provider infrastructure without maintaining local servers.
Question 826
A decision meeting distinguishes between two outcomes: connect a VPC to supported Amazon S3 or DynamoDB services through route-table entries, and connect supported VPC workloads privately to selected AWS services. The first is handled using Gateway VPC endpoint. Which option directly supports the second?
- Internet gateway
- Gateway VPC endpoint
- Security group
- VPC endpoint
Explanation
Correct Answer
D:VPC endpoint addresses the new need to connect supported VPC workloads privately to selected AWS services because VPC endpoints provide service connectivity without requiring a public internet path; Gateway VPC endpoint supports the different existing task to connect a VPC to supported Amazon S3 or DynamoDB services through route-table entries.
Incorrect Answers
A:Internet gateway is intended to enable internet routing for resources in a VPC with suitable configuration because an internet gateway connects a VPC to the internet for eligible public addressing paths; in this design the new outcome is to connect supported VPC workloads privately to selected AWS services, which calls for VPC endpoint rather than Internet gateway or the earlier Gateway VPC endpoint.
B:Gateway VPC endpoint primarily supports the earlier need to connect a VPC to supported Amazon S3 or DynamoDB services through route-table entries because gateway endpoints provide private service paths for S3 and DynamoDB, but the new task is to connect supported VPC workloads privately to selected AWS services; that is why VPC endpoint is preferable here.
C:Security group is intended to enforce stateful inbound and outbound rules on supported resources because security groups act as virtual firewalls associated with network interfaces; in this design the new outcome is to connect supported VPC workloads privately to selected AWS services, which calls for VPC endpoint rather than Security group or the earlier Gateway VPC endpoint.

Question 829
A project owner needs a practical way to reduce time to download reusable web assets in different countries. Which selection most closely aligns with that objective?
- AWS Global Accelerator
- Content delivery latency
- AWS Region
- Multi-Region architecture
Explanation
Correct Answer
B:Content delivery latency matches the goal to reduce time to download reusable web assets in different countries because cDN caching stores content nearer viewers and lowers repeat retrieval distance. The source application still needs an appropriate origin and cache policy. Multi-Region architecture is for the different objective to address disaster recovery or geography-spanning application availability.
Incorrect Answers
A:AWS Global Accelerator addresses the separate need to route user traffic toward healthy regional endpoints through AWS global network paths because global Accelerator uses static anycast IP addresses and endpoint health information to improve availability and performance; it is not as direct as Content delivery latency for the actual requirement to reduce time to download reusable web assets in different countries.
C:AWS Region addresses the separate need to select a geographic area in which to place a workload because an AWS Region is a distinct geographic location containing multiple Availability Zones; it is not as direct as Content delivery latency for the actual requirement to reduce time to download reusable web assets in different countries.
D:Multi-Region architecture addresses the separate need to address disaster recovery or geography-spanning application availability because deploying and replicating across Regions can isolate regional failures and serve separate markets; it is not as direct as Content delivery latency for the actual requirement to reduce time to download reusable web assets in different countries.
