Question 730
A team has chosen On-premises deployment to keep computing equipment operated entirely in an organization's facility. Which description explains the mechanism that makes this selection appropriate?
- The console provides graphical pages to view and configure AWS resources.
- These tools provide language libraries and request handling for application integrations with AWS APIs.
- An on-premises environment remains hosted and administered at the organization's sites.
- The AWS Command Line Interface exposes AWS service operations to terminals and automation.
Explanation
Correct Answer
C:On-premises deployment meets the goal to keep computing equipment operated entirely in an organization's facility because an on-premises environment remains hosted and administered at the organization's sites. It lacks the same provider-operated resource provisioning abstraction.
Incorrect Answers
A:That description belongs to AWS Management Console because the console provides graphical pages to view and configure AWS resources; it is used to perform occasional AWS administration through a browser interface, not to explain how On-premises deployment provides the function to keep computing equipment operated entirely in an organization's facility.
B:That description belongs to AWS SDKs because sDKs provide language libraries and request handling for application integrations with AWS APIs; it is used to integrate AWS service requests directly into application source code, not to explain how On-premises deployment provides the function to keep computing equipment operated entirely in an organization's facility.
D:That description belongs to AWS CLI because the AWS Command Line Interface exposes AWS service operations to terminals and automation; it is used to run scripted AWS API operations from shell commands, not to explain how On-premises deployment provides the function to keep computing equipment operated entirely in an organization's facility.
Question 731
The solution currently handles its need to organize and manage fleets of supported connected devices with AWS IoT Device Management. A new requirement is to find subscribe to and manage eligible third-party software solutions instead. Which service or principle addresses that different need?
- AWS IoT Device Management
- Amazon SNS
- AWS Marketplace
- Amazon SQS
Explanation
Correct Answer
C:AWS Marketplace addresses the new need to find subscribe to and manage eligible third-party software solutions because marketplace is a digital catalog of software data and related offerings; AWS IoT Device Management supports the different existing task to organize and manage fleets of supported connected devices.
Incorrect Answers
A:AWS IoT Device Management primarily supports the earlier need to organize and manage fleets of supported connected devices because ioT device management capabilities help register organize and monitor connected devices, but the new task is to find subscribe to and manage eligible third-party software solutions; that is why AWS Marketplace is preferable here.
B: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 find subscribe to and manage eligible third-party software solutions, which calls for AWS Marketplace rather than Amazon SNS or the earlier AWS IoT Device Management.
D:Amazon SQS is intended to decouple systems with durable asynchronous message queues because sQS holds messages for consumers to process independently; in this design the new outcome is to find subscribe to and manage eligible third-party software solutions, which calls for AWS Marketplace rather than Amazon SQS or the earlier AWS IoT Device Management.
Question 732
For a new AWS implementation, a team must retain long-lived archives at very low storage cost when restoration can be slow. Which available choice is most specifically intended for that function?
- EBS versus EFS storage model
- S3 Glacier Flexible Retrieval
- S3 Glacier Deep Archive
- S3 multi-part upload
Explanation
Correct Answer
C:S3 Glacier Deep Archive matches the goal to retain long-lived archives at very low storage cost when restoration can be slow because deep Archive is designed for extremely infrequent access and long retention. Restore latency and minimum storage duration matter for operational planning. EBS versus EFS storage model is for the different objective to recognize block devices compared with managed network file systems.
Incorrect Answers
A:EBS versus EFS storage model addresses the separate need to recognize block devices compared with managed network file systems because EBS offers block storage attached to instances; EFS offers a shared file system mounted over NFS; it is not as direct as S3 Glacier Deep Archive for the actual requirement to retain long-lived archives at very low storage cost when restoration can be slow.
B:S3 Glacier Flexible Retrieval addresses the separate need to archive data with retrieval time measured in minutes to hours because flexible Retrieval supports lower-cost archival storage using asynchronous restore options; it is not as direct as S3 Glacier Deep Archive for the actual requirement to retain long-lived archives at very low storage cost when restoration can be slow.
D:S3 multi-part upload addresses the separate need to upload very large objects as separately transmitted parts because Multi-part upload improves resilience and transfer management for large S3 objects; it is not as direct as S3 Glacier Deep Archive for the actual requirement to retain long-lived archives at very low storage cost when restoration can be slow.
Question 733
An AWS implementation has already addressed choose an appropriate level of model customization by using Pretrained AI API versus custom ML. Its remaining gap is to build train and deploy custom machine learning models. Which listed capability closes this gap?
- Amazon Bedrock
- Amazon SageMaker AI
- Amazon Lex
- Pretrained AI API versus custom ML
Explanation
Correct Answer
B:Amazon SageMaker AI addresses the new need to build train and deploy custom machine learning models because sageMaker AI offers managed tooling for ML data preparation training and inference workflows; Pretrained AI API versus custom ML supports the different existing task to choose an appropriate level of model customization.
Incorrect Answers
A:Amazon Bedrock is intended to build generative AI applications using foundation models through managed APIs because bedrock provides access to foundation models and tooling for generative AI solutions; in this design the new outcome is to build train and deploy custom machine learning models, which calls for Amazon SageMaker AI rather than Amazon Bedrock or the earlier Pretrained AI API versus custom ML.
C:Amazon Lex is intended to build conversational chat or voice interfaces with intent recognition because lex supports conversational bots using natural language understanding; in this design the new outcome is to build train and deploy custom machine learning models, which calls for Amazon SageMaker AI rather than Amazon Lex or the earlier Pretrained AI API versus custom ML.
D:Pretrained AI API versus custom ML primarily supports the earlier need to choose an appropriate level of model customization because pretrained APIs accelerate common text speech and vision tasks; SageMaker AI supports custom model workflows, but the new task is to build train and deploy custom machine learning models; that is why Amazon SageMaker AI is preferable here.
Question 734
Which AWS service or cloud concept is designed principally to prepare recovery beyond failure of one Availability Zone?
- Global IAM identity scope
- Regional disaster recovery tests
- Content delivery latency
- Regional service scope
- Region outage planning
Explanation
Correct Answer
E:Region outage planning matches the goal to prepare recovery beyond failure of one Availability Zone because a regional recovery design uses another Region and explicit data and traffic recovery plans. Simply adding more subnets in one Region cannot mitigate complete regional unavailability. Regional disaster recovery tests is for the different objective to verify a workload can resume in its backup Region; the requested capability is Region outage planning to prepare recovery beyond failure of one Availability Zone, in contrast with Regional disaster recovery tests to verify a workload can resume in its backup Region.
Incorrect Answers
A:Global IAM identity scope addresses the separate need to manage IAM identities used to authorize actions across AWS Regions because IAM is a global AWS service within an account, while service resources may be regional; it is not as direct as Region outage planning for the actual requirement to prepare recovery beyond failure of one Availability Zone.
B:Regional disaster recovery tests addresses the separate need to verify a workload can resume in its backup Region because recovery exercises check replication, dependencies and traffic-routing procedures before a real incident; it is not as direct as Region outage planning for the actual requirement to prepare recovery beyond failure of one Availability Zone.
C:Content delivery latency addresses the separate need to reduce time to download reusable web assets in different countries because cDN caching stores content nearer viewers and lowers repeat retrieval distance; it is not as direct as Region outage planning for the actual requirement to prepare recovery beyond failure of one Availability Zone.
D:Regional service scope addresses the separate need to recognize that many AWS resources exist only in a selected Region because regional services require selecting the location where supported resources are created; it is not as direct as Region outage planning for the actual requirement to prepare recovery beyond failure of one Availability Zone.
Question 735
An AWS workload is being designed to let private subnet resources initiate eligible outbound internet connections. What is the most appropriate capability or approach?
- AWS Client VPN
- Gateway VPC endpoint
- NAT gateway
- Stateless versus stateful filtering
Explanation
Correct Answer
C:NAT gateway matches the goal to let private subnet resources initiate eligible outbound internet connections because a NAT gateway translates egress traffic when appropriate routes are configured. It does not permit unsolicited public inbound connections to private instances. Gateway VPC endpoint is for the different objective to connect a VPC to supported Amazon S3 or DynamoDB services through route-table entries.
Incorrect Answers
A:AWS Client VPN addresses the separate need to provide individual remote users with a managed VPN connection to AWS or attached networks because client VPN is a client-based remote-access VPN service; it is not as direct as NAT gateway for the actual requirement to let private subnet resources initiate eligible outbound internet connections.
B:Gateway VPC endpoint addresses the separate 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; it is not as direct as NAT gateway for the actual requirement to let private subnet resources initiate eligible outbound internet connections.
D:Stateless versus stateful filtering addresses the separate need to select whether connection return traffic needs independent explicit rules because security groups track allowed connections while network ACLs evaluate both directions without state; it is not as direct as NAT gateway for the actual requirement to let private subnet resources initiate eligible outbound internet connections.
Question 736
A team already uses Storage optimized EC2 instance to run applications needing high local storage IOPS or throughput. It now must use temporary host-attached storage with very low latency, which is a separate requirement. What should it select for that new objective?
- EC2 instance store
- Amazon EC2
- AWS Lambda
- Storage optimized EC2 instance
Explanation
Correct Answer
A:EC2 instance store addresses the new need to use temporary host-attached storage with very low latency because instance store volumes are physically associated with the host and have ephemeral characteristics; Storage optimized EC2 instance supports the different existing task to run applications needing high local storage IOPS or throughput.
Incorrect Answers
B:Amazon EC2 is intended to operate virtual servers with explicit OS and instance management because EC2 provides configurable compute instances where customers manage guest OS and application software; in this design the new outcome is to use temporary host-attached storage with very low latency, which calls for EC2 instance store rather than Amazon EC2 or the earlier Storage optimized EC2 instance.
C:AWS Lambda is intended to execute event-triggered code without managing virtual servers because lambda runs functions in managed execution environments with service-defined execution constraints; in this design the new outcome is to use temporary host-attached storage with very low latency, which calls for EC2 instance store rather than AWS Lambda or the earlier Storage optimized EC2 instance.
D:Storage optimized EC2 instance primarily supports the earlier need to run applications needing high local storage IOPS or throughput because storage-optimized families offer specialized local storage performance for eligible workloads, but the new task is to use temporary host-attached storage with very low latency; that is why EC2 instance store is preferable here.
Question 737
The workload already uses VPC peering to connect two VPCs privately for their routable address ranges. A second workstream needs to connect supported VPC workloads privately to selected AWS services. Which AWS choice fits the second workstream?
- Internet gateway
- VPC endpoint
- Security group
- VPC peering
Explanation
Correct Answer
B: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; VPC peering supports the different existing task to connect two VPCs privately for their routable address ranges.
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 VPC peering.
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 VPC peering.
D:VPC peering primarily supports the earlier need to connect two VPCs privately for their routable address ranges because peering allows traffic between eligible VPCs with non-overlapping CIDRs and appropriate routes, but the new task is to connect supported VPC workloads privately to selected AWS services; that is why VPC endpoint is preferable here.
Question 738
A decision meeting distinguishes between two outcomes: operate a managed relational database engine, and reduce avoidable connection pressure on an RDS application backend. The first is handled using Amazon RDS. Which option directly supports the second?
- DynamoDB global tables
- Amazon ElastiCache
- Database connection management
- Amazon RDS
Explanation
Correct Answer
C:Database connection management addresses the new need to reduce avoidable connection pressure on an RDS application backend because managed connection proxies such as RDS Proxy can pool connections for suitable engines; Amazon RDS supports the different existing task to operate a managed relational database engine.
Incorrect Answers
A:DynamoDB global tables is intended to provide multi-Region active-active replication for a DynamoDB application because global tables replicate supported data across selected Regions for regional workloads; in this design the new outcome is to reduce avoidable connection pressure on an RDS application backend, which calls for Database connection management rather than DynamoDB global tables or the earlier Amazon RDS.
B:Amazon ElastiCache is intended to cache frequently accessed application data in memory because elastiCache offers managed in-memory caching engines to reduce repetitive backend reads; in this design the new outcome is to reduce avoidable connection pressure on an RDS application backend, which calls for Database connection management rather than Amazon ElastiCache or the earlier Amazon RDS.
D:Amazon RDS primarily supports the earlier need to operate a managed relational database engine because RDS automates selected relational database operations including backup and patching, but the new task is to reduce avoidable connection pressure on an RDS application backend; that is why Database connection management is preferable here.
Question 739
The solution currently handles its need to provide managed cloud virtual desktop environments with Amazon WorkSpaces. A new requirement is to provide remote browser isolation for selected web access needs instead. Which service or principle addresses that different need?
- AWS Amplify
- Amazon Cognito
- Amazon WorkSpaces Secure Browser
- Amazon WorkSpaces
Explanation
Correct Answer
C:Amazon WorkSpaces Secure Browser addresses the new need to provide remote browser isolation for selected web access needs because workSpaces Secure Browser streams a controlled browsing session from the cloud; Amazon WorkSpaces supports the different existing task to provide managed cloud virtual desktop environments.
Incorrect Answers
A:AWS Amplify is intended to build and host web or mobile application frontends with integrated workflows because amplify provides frontend deployment and backend integrations for app teams; in this design the new outcome is to provide remote browser isolation for selected web access needs, which calls for Amazon WorkSpaces Secure Browser rather than AWS Amplify or the earlier Amazon WorkSpaces.
B:Amazon Cognito is intended to provide sign-up sign-in and identity features for customer-facing applications because cognito supports application user directories and federation; in this design the new outcome is to provide remote browser isolation for selected web access needs, which calls for Amazon WorkSpaces Secure Browser rather than Amazon Cognito or the earlier Amazon WorkSpaces.
D:Amazon WorkSpaces primarily supports the earlier need to provide managed cloud virtual desktop environments because workSpaces delivers desktop computing to remote users, but the new task is to provide remote browser isolation for selected web access needs; that is why Amazon WorkSpaces Secure Browser is preferable here.
Question 740
While reviewing a design, an architect identifies a gap: the workload needs to hold scratch data temporarily on host-attached disks. Which option closes that gap most directly?
- Amazon S3 Standard
- Amazon S3 Standard-IA
- S3 pre-signed URL
- EC2 instance store
Explanation
Correct Answer
D:EC2 instance store matches the goal to hold scratch data temporarily on host-attached disks because instance store provides fast ephemeral data storage tied to the host. Host loss or instance termination can lose data stored only there. S3 pre-signed URL is for the different objective to grant time-limited access to a specific object operation under signing credentials.
Incorrect Answers
A:Amazon S3 Standard addresses the separate need to serve frequently accessed objects with low-latency retrieval because S3 Standard is appropriate for data requiring regular access across multiple AZs; it is not as direct as EC2 instance store for the actual requirement to hold scratch data temporarily on host-attached disks.
B:Amazon S3 Standard-IA addresses the separate need to store infrequently accessed objects that still need rapid retrieval because standard-IA offers lower storage cost for lower access frequency with retrieval charges; it is not as direct as EC2 instance store for the actual requirement to hold scratch data temporarily on host-attached disks.
C:S3 pre-signed URL addresses the separate need to grant time-limited access to a specific object operation under signing credentials because a pre-signed URL encodes a limited request authorization with expiration; it is not as direct as EC2 instance store for the actual requirement to hold scratch data temporarily on host-attached disks.
