Question 340

For the enterprise requirement "An enterprise wants line-item chargeback for data transfer and service usage across hundreds of accounts", the team implemented this change: Export AWS Cost and Usage Reports to S3 and query them with Athena or a billing data analysis workflow. Which evidence confirms the intended behavior under test?

  1. Revoking a staff member's assignment removes their delegated access without per-account user deletion
  2. Tested resized instances meet p95 latency goals while recommended savings are observed
  3. Finance can reconcile detailed usage line items to accounts and cost categories
  4. Eligible compute charges reflect the planned commitment discount and remaining coverage is visible

Explanation

Correct Answer

C:

This measures the behavior required by the specific solution, rather than simply checking that it was configured. The Cost and Usage Report provides detailed billing facts for accountable cost analysis. The acceptance condition is linked directly to the scenario: An enterprise wants line-item chargeback for data transfer and service usage across hundreds of accounts.

Incorrect Answers

A:

Revoking a staff member's assignment removes their delegated access without per-account user deletion. However, this does not establish the required outcome: finance can reconcile detailed usage line items to accounts and cost categories.

B:

Tested resized instances meet p95 latency goals while recommended savings are observed. However, this does not establish the required outcome: finance can reconcile detailed usage line items to accounts and cost categories.

D:

Eligible compute charges reflect the planned commitment discount and remaining coverage is visible. However, this does not establish the required outcome: finance can reconcile detailed usage line items to accounts and cost categories.

Question 341

An architecture review recommends this solution: Deploy organization-managed AWS Config rules and targeted auto-remediation through approved Systems Manager Automation. The motivating situation is: Regulators require consistent detection and correction of publicly accessible S3 buckets across a multi-account organization. Which technical principle most strongly justifies this recommendation?

  1. Security Hub delegated administration centralizes findings while each source account retains its own resources
  2. Global tables provide multi-Region replication with eventual cross-Region convergence semantics
  3. IAM Identity Center coordinates workforce SSO permission sets across accounts
  4. Organization-level Config rules continuously evaluate configuration and can launch controlled remediations

Explanation

Correct Answer

D:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Deploy organization-managed AWS Config rules and targeted auto-remediation through approved Systems Manager Automation. The expected supporting evidence is: A noncompliant test bucket is flagged and the remediation removes its unauthorized public exposure.

Incorrect Answers

A:

Individual Security Hub instances were not centrally delegated or aggregated. The stated evidence instead indicates: Per-account one-off inspections do not continuously evaluate drift across accounts.

B:

A single-Region DynamoDB table cannot accept the required local writes after that Region fails. The stated evidence instead indicates: Per-account one-off inspections do not continuously evaluate drift across accounts.

C:

Individual IAM users were being created per account instead of using centralized workforce federation. The stated evidence instead indicates: Per-account one-off inspections do not continuously evaluate drift across accounts.

Question 342

For the enterprise requirement "An EC2 application requires private access to AWS Secrets Manager and S3 without traversing public network routes", the team implemented this change: Use the applicable interface and gateway VPC endpoints and restrict endpoint policies and subnet routes as needed. What should operations verify instead of relying on configuration alone?

  1. A seeded supported suspicious event generates a finding and the delegated administrator can triage it
  2. Cloud instances access approved services privately while disallowed API paths are rejected
  3. Failure of one Region does not interrupt healthy remaining regional capacity under synthetic load
  4. CloudFront retrieves approved objects while direct anonymous S3 URLs are rejected

Explanation

Correct Answer

B:

This measures the behavior required by the specific solution, rather than simply checking that it was configured. VPC endpoints provide private connectivity to supported AWS services inside defined network and policy controls. The acceptance condition is linked directly to the scenario: An EC2 application requires private access to AWS Secrets Manager and S3 without traversing public network routes.

Incorrect Answers

A:

A seeded supported suspicious event generates a finding and the delegated administrator can triage it. However, this does not establish the required outcome: cloud instances access approved services privately while disallowed API paths are rejected.

C:

Failure of one Region does not interrupt healthy remaining regional capacity under synthetic load. However, this does not establish the required outcome: cloud instances access approved services privately while disallowed API paths are rejected.

D:

CloudFront retrieves approved objects while direct anonymous S3 URLs are rejected. However, this does not establish the required outcome: cloud instances access approved services privately while disallowed API paths are rejected.

Question 343

A deployed environment still does not meet the original requirement: An incident reviewer needs a timeline of a suspicious IAM policy change made across member accounts. Which root cause is most consistent with the observation?

  1. Findings remain siloed in local account consoles and cannot be triaged centrally
  2. CloudTrail management events are not retained or centrally available for review
  3. Resource-based trust was not evaluated beyond local IAM identity permission reports
  4. Standard short-lived backups cannot recover the exact chosen accidental-update point

Explanation

Correct Answer

B:

This is the technical design error aligned with the unmet requirement. CloudTrail API event evidence supports investigation of changes to account control-plane resources. The appropriate correction is: Aggregate CloudTrail management events with appropriately protected central storage and searchable event records. The control should then be tested by verifying that The actor, source and changed policy action appear in audit events from the affected account.

Incorrect Answers

A:

Findings remain siloed in local account consoles and cannot be triaged centrally. The stated evidence instead indicates: CloudTrail management events are not retained or centrally available for review.

C:

Resource-based trust was not evaluated beyond local IAM identity permission reports. The stated evidence instead indicates: CloudTrail management events are not retained or centrally available for review.

D:

Standard short-lived backups cannot recover the exact chosen accidental-update point. The stated evidence instead indicates: CloudTrail management events are not retained or centrally available for review.

Question 344

A professional architect is reviewing two independent workstreams. Requirement A: An SNS topic invokes an asynchronous HTTP subscriber with intermittent failures and business needs controlled redelivery. Requirement B: Several member accounts buy overlapping Reserved Instances, yet unused reservations remain in the organization. Which TWO recommendations jointly satisfy requirements A and B?

  1. Configure readiness probes, deployment surge policy and graceful termination semantics
  2. Configure the supported subscription delivery policy, retries and dead-letter queue where applicable
  3. Review RI utilization, supported reservation sharing and regional family coverage before buying more
  4. Add AWS Config evaluation for the risky security-group condition with controlled notification and remediation
  5. Analyze transfer usage in CUR and network metrics; redesign unnecessary cross-AZ chatty application flows

Explanation

Correct Answers

B:

This action meets the independently stated requirement A: An SNS topic invokes an asynchronous HTTP subscriber with intermittent failures and business needs controlled redelivery. SNS subscriber reliability relies on delivery retries and appropriately configured dead-letter destinations. A direct acceptance check is: Failed deliveries retry under the configured policy and exhausted messages reach the DLQ.

C:

This action meets the independently stated requirement B: Several member accounts buy overlapping Reserved Instances, yet unused reservations remain in the organization. RI coverage should be evaluated at consolidated billing scope where sharing is enabled. A direct acceptance check is: Discount usage improves with fewer unused reservation hours and measured baseline cost changes.

Incorrect Answers

A:

This action targets a different technical need: An EKS service experiences 503 errors during rolling updates because pods accept traffic before dependencies initialize. It does not replace either required solution in A or B. Readiness and graceful termination controls reduce errors during normal rolling changes; verify the two stated requirements independently rather than accepting an unrelated change.

D:

This action targets a different technical need: An engineer repeatedly leaves management ports publicly accessible despite a configuration guardrail document. It does not replace either required solution in A or B. AWS Config checks configuration changes against evaluable rules and supports managed remediation actions; verify the two stated requirements independently rather than accepting an unrelated change.

E:

This action targets a different technical need: A global network has rising cross-AZ and inter-Region transfer bills despite healthy compute utilization. It does not replace either required solution in A or B. Placement and traffic pattern matter to data transfer costs as much as raw compute prices; verify the two stated requirements independently rather than accepting an unrelated change.

Question 345

For the enterprise requirement "A large retail monolith has tightly coupled inventory, checkout and customer modules that scale as one deployment", the team implemented this change: Identify bounded contexts and isolate independently deployable modules with explicit APIs and data ownership. What should operations verify instead of relying on configuration alone?

  1. A fresh environment can be recreated from code with predictable parameters and drift checks
  2. Vendor-certified testing proves that the appliance runs on the selected target or requires retain/replace decision
  3. Source and destination data reconcile, CDC lag reaches the target and switching endpoints remains reversible
  4. Inventory changes can deploy without forcing unrelated checkout and customer workflows through full regression

Explanation

Correct Answer

D:

This measures the behavior required by the specific solution, rather than simply checking that it was configured. Domain-aligned service boundaries require APIs and deliberate data ownership separation. The acceptance condition is linked directly to the scenario: A large retail monolith has tightly coupled inventory, checkout and customer modules that scale as one deployment.

Incorrect Answers

A:

A fresh environment can be recreated from code with predictable parameters and drift checks. However, this does not establish the required outcome: inventory changes can deploy without forcing unrelated checkout and customer workflows through full regression.

B:

Vendor-certified testing proves that the appliance runs on the selected target or requires retain/replace decision. However, this does not establish the required outcome: inventory changes can deploy without forcing unrelated checkout and customer workflows through full regression.

C:

Source and destination data reconcile, CDC lag reaches the target and switching endpoints remains reversible. However, this does not establish the required outcome: inventory changes can deploy without forcing unrelated checkout and customer workflows through full regression.

Question 346

An enterprise architecture team faces this design requirement: A latency-sensitive API running in EKS cannot tolerate a single Availability Zone outage. What design change should the team implement?

  1. Distribute worker nodes and eligible pods across multiple AZs with topology rules and disruption-aware service routing
  2. Enable EventBridge event-bus archive and replay for eligible matching events
  3. Enable IAM Access Analyzer for the relevant zone of trust and evaluate the external-access finding
  4. Use AWS Elastic Disaster Recovery with supported source replication and recovery drills

Explanation

Correct Answer

A:

Multi-AZ Kubernetes workloads need scheduled replicas and correctly configured networking across zones. The required architecture outcome is: A latency-sensitive API running in EKS cannot tolerate a single Availability Zone outage. Validate this choice by checking that Draining all nodes in one zone still leaves enough healthy replicas serving traffic from others.

Incorrect Answers

B:

No archive or retention mechanism was configured before the subscriber outage. The specific problem here is that all service replicas were scheduled in one zone despite multi-AZ infrastructure.

C:

Resource policies were never checked for access beyond the organization's trust boundary. The specific problem here is that all service replicas were scheduled in one zone despite multi-AZ infrastructure.

D:

Backup images exist but no continuously replicated recovery environment or launch plan is configured. The specific problem here is that all service replicas were scheduled in one zone despite multi-AZ infrastructure.

Question 347

For the enterprise requirement "A busy event-routing platform must retain dropped partner events for later controlled replay after a bug fix", the team implemented this change: Configure EventBridge archives and event replay with selection patterns and measured retention. Which outcome is the most meaningful acceptance test?

  1. Events captured during the fault can be replayed to a corrected consumer after recovery
  2. Excess requests return expected throttling responses while permitted traffic continues under peak simulation
  3. A poison message goes to the DLQ after configured attempts while valid following messages proceed
  4. The load balancer continues serving from healthy remaining tasks during a forced zone failure

Explanation

Correct Answer

A:

This measures the behavior required by the specific solution, rather than simply checking that it was configured. EventBridge event archives retain matching historical events for later replay. The acceptance condition is linked directly to the scenario: A busy event-routing platform must retain dropped partner events for later controlled replay after a bug fix.

Incorrect Answers

B:

Excess requests return expected throttling responses while permitted traffic continues under peak simulation. However, this does not establish the required outcome: events captured during the fault can be replayed to a corrected consumer after recovery.

C:

A poison message goes to the DLQ after configured attempts while valid following messages proceed. However, this does not establish the required outcome: events captured during the fault can be replayed to a corrected consumer after recovery.

D:

The load balancer continues serving from healthy remaining tasks during a forced zone failure. However, this does not establish the required outcome: events captured during the fault can be replayed to a corrected consumer after recovery.

Question 348

An architecture review recommends this solution: Introduce a centrally managed translation or proxy layer with nonoverlapping service endpoints rather than directly peering overlapping networks. The motivating situation is: Two acquired subsidiaries have overlapping RFC1918 VPC CIDRs but must exchange traffic with a shared integration endpoint. Which statement explains why the recommendation solves the specific problem?

  1. VPC sharing separates network ownership from application resource ownership
  2. Transit Gateway peering requires explicit routing between the regional gateways
  3. Stateful network inspection requires symmetric paths through the selected inspection appliance
  4. Overlapping address spaces require translation or service-level isolation rather than simple routed peering

Explanation

Correct Answer

D:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Introduce a centrally managed translation or proxy layer with nonoverlapping service endpoints rather than directly peering overlapping networks. The expected supporting evidence is: Traffic uses translated unique endpoint addresses and return packets reach the original client correctly.

Incorrect Answers

A:

Separate VPC copies and peering links were created instead of sharing centrally governed subnets. The stated evidence instead indicates: Overlapping network prefixes make ordinary VPC peering route selection ambiguous.

B:

The architecture assumes that Transit Gateway peering automatically propagates interregional routes. The stated evidence instead indicates: Overlapping network prefixes make ordinary VPC peering route selection ambiguous.

C:

The inspection design allows forward and return packets to use different stateful inspection appliances. The stated evidence instead indicates: Overlapping network prefixes make ordinary VPC peering route selection ambiguous.

Question 349

A deployed environment still does not meet the original requirement: A monolithic Windows process has been decomposed into HTTP services that can run in managed containers without operating its own servers. What design flaw is the best match for the reported condition?

  1. All assets are scheduled for direct rehost even when some are obsolete or unsuitable
  2. Dedicated EC2 servers remain the scaling bottleneck for stateless containerized workloads
  3. Developers assume SQS has identical JMS or broker feature semantics to the source stack
  4. All analytics jobs depend on a single custom ETL server and its directly attached storage

Explanation

Correct Answer

B:

This is the technical design error aligned with the unmet requirement. Fargate can run supported ECS container tasks without customer-managed worker hosts. The appropriate correction is: Package services into supported containers and deploy with ECS on Fargate and scalable load balancing. The control should then be tested by verifying that Services scale independently and teams do not manage EC2 container worker hosts.

Incorrect Answers

A:

All assets are scheduled for direct rehost even when some are obsolete or unsuitable. The stated evidence instead indicates: Dedicated EC2 servers remain the scaling bottleneck for stateless containerized workloads.

C:

Developers assume SQS has identical JMS or broker feature semantics to the source stack. The stated evidence instead indicates: Dedicated EC2 servers remain the scaling bottleneck for stateless containerized workloads.

D:

All analytics jobs depend on a single custom ETL server and its directly attached storage. The stated evidence instead indicates: Dedicated EC2 servers remain the scaling bottleneck for stateless containerized workloads.

Question 350

An architecture review recommends this solution: Evaluate EFS throughput and performance modes and provision an appropriate supported throughput setting. The motivating situation is: A shared EFS file system slows a data-processing batch even though compute workers are mostly idle. Why does this approach fit the stated design constraints?

  1. RDS read replicas scale read throughput but are asynchronous relative to the primary
  2. Pilot light retains critical replicated services while reconstructing additional capacity during recovery
  3. Kinesis stream performance depends on provisioned or on-demand capacity and balanced partition keys
  4. EFS throughput characteristics must match concurrent IO patterns and required sustained rate

Explanation

Correct Answer

D:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Evaluate EFS throughput and performance modes and provision an appropriate supported throughput setting. The expected supporting evidence is: File-system throughput reaches target under representative concurrent processing without exhausted credits.

Incorrect Answers

A:

Read-only analytical traffic saturates the production database's single writable instance. The stated evidence instead indicates: The shared file system's throughput mode or credit availability constrains parallel clients.

B:

Every component must be rebuilt from scratch after failure, despite a tighter RTO. The stated evidence instead indicates: The shared file system's throughput mode or credit availability constrains parallel clients.

C:

Stream shard limits or skewed partition keys cannot handle incoming record throughput. The stated evidence instead indicates: The shared file system's throughput mode or credit availability constrains parallel clients.
