A board report shows that all scheduled backups completed successfully last month. The organization nevertheless has no evidence that its 45-minute recovery objective can be met. Multiple accounts use different application stacks. What should the architect add to the recovery program?

Select one answerAMeasure only the infrastructure restore task and omit application startup and transaction validation.BUse successful backup-job status as the sole evidence that application recovery fits the RTO.CExtend retention without measuring how long the current data volume and dependencies take to recover.DPerform scheduled restore exercises with application-level validation, record elapsed recovery time and data age, and remediate results that miss the objectives.

An existing checkout request crosses API Gateway, Lambda, and several backend calls. Aggregate metrics show acceptable averages, but some users experience multi-second latency. The team cannot identify which dependency causes the slow requests. Which observability improvement is most useful?

Select one answerAAdd distributed tracing and correlated structured logs, then inspect slow end-to-end traces alongside service metrics.BIncrease timeouts across all dependencies before identifying the slow request segment.CAdd more copies of the average-latency dashboard without tracing individual slow paths.DCollect only aggregate request counts without correlating timing across the backend calls.

An existing Spot-based worker fleet occasionally loses long-running jobs when instances are reclaimed. The jobs support checkpointing, but progress currently remains only on local storage. What should the team change?

Select one answerARely on receiving enough interruption notice to save all progress for every possible failure.BPersist checkpoints to durable storage and integrate interruption handling and retry-safe rescheduling into the worker workflow.CIncrease the Spot bid as a guarantee against capacity reclamation.DKeep checkpoints only on the worker's instance-store volumes.

A monolith publishes one internal event that several new services will consume for different purposes. The services need independent scaling and retry behavior, and routing rules may evolve as more consumers are added. Which architecture is appropriate?

Select one answerAKeep every consumer synchronously coupled to the producer's transaction.BUse an event-routing layer such as EventBridge with consumer-specific durable queues and monitored delivery and processing failures where required.CUse shared retry state that prevents one consumer from advancing independently of another consumer's failure.DUse one competing-consumer queue even though each service must receive a separate event copy.

A new commerce platform expects operational transactions throughout the day and large analytical joins over historical data. The analytics team can tolerate delayed data ingestion. The architect must prevent analytical scans from competing with the transaction path. Which design fits?

Select one answerAKeep operational transactions in the appropriate transactional store and feed a separate analytical platform through a controlled ingestion process.BUse a replica without checking whether its engine and capacity fit the large analytical join workload.CShare one fixed resource pool and give analytical scans priority over the required transaction path.DRun historical scans directly against the transactional writer during peak order processing.

A portfolio review finds that an internally maintained collaboration application provides standard capabilities available in an approved SaaS product. Business owners accept the SaaS functionality, and the main work is moving data and users rather than preserving the old runtime. Which migration strategy describes this choice?

Select one answerARetain, continuing the current application and operating model unchanged.BRetire without replacement, even though the collaboration capability remains required.CRepurchase, with a controlled transition of data, identities, integrations, and operating responsibilities to the selected product.DRehost, preserving the existing runtime as the service implementation.

A payments analytics service must keep customer records within approved European Regions. Users are spread across several countries. The architect must choose the primary Region and an independent recovery Region while meeting an agreed interactive latency target. Which selection process is most defensible?

Select one answerAChoose two Availability Zones in the primary Region and use them as the two independent regional recovery locations.BFilter Regions by residency and required service availability, then measure representative user and dependency latency before selecting the primary and recovery pair.CChoose the lowest-price eligible primary Region but permit unrestricted recovery placement if the primary fails.DChoose the Region nearest headquarters and select its closest neighbor without measuring the distributed users' latency.

After an application release, daily cost rises while customer traffic stays stable. The team wants to detect similar regressions earlier and investigate the responsible service. Which operating improvement is most appropriate?

Select one answerACombine suitable budgets or anomaly alerts with deployment context and granular cost analysis, then verify the suspected resource or usage change.BResize all compute immediately without identifying which service or usage dimension increased.CTreat deployment success as proof of unchanged resource and transfer usage.DWait for the annual threshold before investigating a daily cost regression.

A Windows application is moving to AWS and requires SMB shares joined to the corporate Active Directory. Its availability target requires continued file-service operation after an Availability Zone failure. Which managed storage deployment should the architect select?

Select one answerAUse an object API without a compatible SMB and Active Directory file-service layer.BUse one manually shared instance volume with no independent failover design.CAn appropriate Multi-AZ Amazon FSx for Windows File Server deployment with supported Active Directory connectivity and validated client failover behavior.DUse a Single-AZ file-server deployment as the zonal-failure solution.

An existing database shows many short-lived sessions and connection-limit failures during application bursts. Query execution is usually fast once a connection is obtained. The engine is supported by RDS Proxy. Which remediation should be evaluated first?

Select one answerAIntroduce RDS Proxy or appropriate application connection pooling, then validate transaction behavior, pool reuse, and database load under bursts.BAdd application concurrency while retaining the same short-lived direct connection behavior.CResize storage performance without evidence that query I/O is the cause of the session failures.DChange only DNS configuration without altering connection reuse or database connection limits.

A telemetry provider exposes a UDP ingestion service from two AWS Regions. Remote factories require stable allowlist IP addresses, and the company wants traffic to enter the AWS global network near each factory and move away from unhealthy regional endpoints. Which front door fits these constraints?

Select one answerARoute 53 latency records for the regional endpoints with client allowlists based on their changing resolved addresses.BA CloudFront distribution with the regional UDP collectors configured as origins.CAn AWS Global Accelerator standard accelerator with static anycast addresses and regional endpoint groups for the UDP service.DA single regional Network Load Balancer with zonal static addresses and no second-Region traffic-routing layer.

A company chooses pilot light for a new multi-tier service. Replicated data and core dependencies run in the recovery Region, while application capacity will be provisioned during recovery. What test most directly demonstrates whether the 30-minute RTO is realistic?

Select one answerAExecute the complete recovery runbook, including quota checks, provisioning, data activation, traffic switching, and a successful business transaction under representative load.BMeasure database replication alone and exclude application provisioning from the recovery-time measurement.CMeasure DNS propagation only and assume quota and application initialization time is negligible.DValidate template syntax without launching or exercising the recovery resources.

An organization has a stable hourly compute baseline but frequently changes EC2 instance families and also uses Fargate and Lambda. It accepts a term commitment for that baseline and wants eligible usage flexibility. Which purchasing strategy is appropriate?

Select one answerABuy family-specific commitments for a forecast peak that includes usage across unrelated families and services.BUse fixed-capacity reservations alone as the discount mechanism for the entire cross-service baseline.CBuy against the highest observed hour and assume unused hourly commitment carries forward indefinitely.DPurchase Compute Savings Plans sized to the measured stable eligible spend, leaving uncertain growth outside the commitment.

A new order event must trigger invoicing, fulfillment, and analytics independently. A temporary failure in analytics must not block fulfillment, and each consumer needs its own retry history. Which messaging design provides this separation?

Select one answerACall the subscribers synchronously inside the order request and retry them as one unit.BPublish the event to SNS and deliver it to a separate SQS queue for each consumer, with consumer-specific retry and dead-letter handling.CUse one shared retry queue whose processing failure prevents all subscribers from advancing independently.DUse one competing-consumer queue when every downstream service requires its own event copy.
