Amazon EMR is associated with a different use case: a team wants managed compute for large-scale big-data frameworks such as Apache Spark. EMR runs supported distributed analytics frameworks and is not a relational transaction service. The question instead focuses on an application wants to capture and process a continuous stream of event records; Amazon Kinesis is the more direct match.

Amazon Athena is associated with a different use case: an analyst needs to query data already stored in S3 using SQL without provisioning a database server. Athena is a serverless interactive query service for supported data sources such as S3. The question instead focuses on an application wants to capture and process a continuous stream of event records; Amazon Kinesis is the more direct match.

Amazon Rekognition is associated with a different use case: a media team wants managed analysis of image or video content without developing its own vision model. Rekognition applies pretrained computer vision to supported image and video analysis tasks. The question instead focuses on an application wants to capture and process a continuous stream of event records; Amazon Kinesis is the more direct match.

Global reach instead focuses on a different requirement, such as a software provider wants to serve customers from multiple continents without building overseas data centers. AWS Regions enable deployment in multiple geographies without building and operating a physical data center in each market. It is not the primary match for the requirement described here: delegate physical infrastructure operation to the cloud provider.

Storage durability instead focuses on a different requirement, such as a photo service needs stored customer pictures to remain intact despite individual storage hardware failures. Durability describes the likelihood that stored data remains intact; it is different from immediate service accessibility. It is not the primary match for the requirement described here: delegate physical infrastructure operation to the cloud provider.

Elasticity instead focuses on a different requirement, such as an online store has unpredictable weekend traffic spikes followed by quiet weekdays. Elasticity aligns live capacity with changing workload demand so idle peak-sized resources do not remain continuously allocated. It is not the primary match for the requirement described here: delegate physical infrastructure operation to the cloud provider.

This statement is true of Rapid experimentation, which addresses a product group wants to run several short-lived proofs of concept at low initial commitment. It does not explain the particular role of Agility; Cloud agility helps teams provision resources quickly and test business ideas without waiting for lengthy hardware procurement.

This statement is true of Fault tolerance, which addresses a payment-processing workload must continue processing transactions when an individual component unexpectedly fails. It does not explain the particular role of Agility; Cloud agility helps teams provision resources quickly and test business ideas without waiting for lengthy hardware procurement.

This statement is true of Pay-as-you-go consumption, which addresses a seasonal nonprofit wants computing only during a two-week annual campaign. It does not explain the particular role of Agility; Cloud agility helps teams provision resources quickly and test business ideas without waiting for lengthy hardware procurement.

This describes a scenario for S3 storage-class pricing: compare storage duration, retrieval charges and access characteristics of S3 classes. S3 storage classes have distinct storage, retrieval and minimum-duration attributes that influence total cost. It is not the most direct example of On-Demand Capacity Reservations.

This describes a scenario for AWS data transfer charges: account for service- and route-dependent data transfer pricing. Data entering AWS is often priced differently from outbound or cross-Region traffic; actual charges depend on service and path. It is not the most direct example of On-Demand Capacity Reservations.

This describes a scenario for On-Demand EC2 pricing: pay for eligible compute usage without a long-term purchase commitment. On-Demand pricing gives flexible capacity for irregular or new workloads, generally without the discounts of eligible commitments. It is not the most direct example of On-Demand Capacity Reservations.

The roles are swapped. AWS Backup is associated with use AWS Backup to manage backup plans and retention for supported services; AWS Storage Gateway instead has the role: Use AWS Storage Gateway to bridge local storage access to AWS. Storage Gateway supports hybrid storage patterns and local caching for selected AWS-backed interfaces.

The roles are swapped. Amazon EFS is associated with use Amazon Elastic File System for managed shared file storage; AWS Storage Gateway instead has the role: Use AWS Storage Gateway to bridge local storage access to AWS. Storage Gateway supports hybrid storage patterns and local caching for selected AWS-backed interfaces.

The roles are swapped. EC2 instance store is associated with use instance store for eligible ephemeral EC2 local storage; AWS Storage Gateway instead has the role: Use AWS Storage Gateway to bridge local storage access to AWS. Storage Gateway supports hybrid storage patterns and local caching for selected AWS-backed interfaces.

This outcome fits AWS Direct Connect: Direct Connect provides private physical network connectivity through supported locations; encryption is a separate consideration. The stakeholder requires the more specific capability provided by Amazon Route 53, not that separate benefit.

This outcome fits Security groups: Security groups control permitted traffic for associated resources and automatically allow response traffic to allowed flows. The stakeholder requires the more specific capability provided by Amazon Route 53, not that separate benefit.

This outcome fits AWS Transit Gateway: Transit Gateway acts as a regional routing hub for supported VPC and network attachments. The stakeholder requires the more specific capability provided by Amazon Route 53, not that separate benefit.

This statement is true of AWS Backup, which addresses a company needs centralized policies and visibility across supported AWS resource backups. It does not explain the particular role of Amazon EBS; EBS provides network-attached block volumes with persistence and snapshot capabilities subject to volume type and configuration.

This statement is true of S3 Glacier Deep Archive, which addresses a regulator requires long-term retention of records that will almost never be retrieved. It does not explain the particular role of Amazon EBS; EBS provides network-attached block volumes with persistence and snapshot capabilities subject to volume type and configuration.

This statement is true of S3 Standard-Infrequent Access, which addresses a business rarely accesses certain long-lived backup files but needs them rapidly when requested. It does not explain the particular role of Amazon EBS; EBS provides network-attached block volumes with persistence and snapshot capabilities subject to volume type and configuration.

This describes a scenario for Reduced infrastructure maintenance: delegate physical infrastructure operation to the cloud provider. AWS handles the facilities and underlying physical infrastructure, freeing customers from those data-center tasks. It is not the most direct example of Global reach.

This describes a scenario for Edge content delivery: cache frequently requested content at locations closer to end users. An edge content delivery network reduces distance to cached content and can improve latency for geographically distributed users. It is not the most direct example of Global reach.

This describes a scenario for High availability: keep the application accessible by using redundant resources and eliminating single points of failure. High availability focuses on minimizing service interruptions through redundancy and service continuity. It is not the most direct example of Global reach.

This statement is true of AWS IoT Core, which addresses a manufacturer wants connected devices to exchange messages securely with cloud applications. It does not explain the particular role of Amazon Connect; Amazon Connect offers contact-center services, distinct from a general-purpose messaging queue.

This statement is true of Amazon EventBridge, which addresses a SaaS app emits business events that must be routed to different AWS targets based on rules. It does not explain the particular role of Amazon Connect; Amazon Connect offers contact-center services, distinct from a general-purpose messaging queue.
