Question 240

A professional architect is reviewing two independent workstreams. Requirement A: A central audit account needs immutable delivery of logs from all workload accounts and Regions. Requirement B: A department must be notified promptly when monthly spending exceeds its threshold. Select TWO actions, one for each independently scoped requirement.

  1. Use organization-wide CloudTrail and central log storage with restrictive bucket access and retention controls
  2. Share the eligible Transit Gateway using AWS Resource Access Manager and explicit attachment routing permissions
  3. Enable EventBridge event-bus archive and replay for eligible matching events
  4. Create an AWS Budget with defined threshold notification recipients and appropriate budget filters
  5. Activate standardized cost allocation tags and enforce tagging through governance processes

Explanation

Correct Answers

A:

This action meets the independently stated requirement A: A central audit account needs immutable delivery of logs from all workload accounts and Regions. An organization trail and protected storage form a centralized account-wide auditing design. A direct acceptance check is: A new workload account's API activity appears in the central log bucket and member administrators cannot erase it.

D:

This action meets the independently stated requirement B: A department must be notified promptly when monthly spending exceeds its threshold. AWS Budgets supports spend targets and notifications on actual or forecasted cost. A direct acceptance check is: A controlled threshold breach yields the expected forecast or actual spend notification.

Incorrect Answers

B:

This action targets a different technical need: A central networking account must share an existing Transit Gateway with application accounts without duplicating it. It does not replace either required solution in A or B. AWS RAM can share supported resources while ownership remains in a central account; verify the two stated requirements independently rather than accepting an unrelated change.

C:

This action targets a different technical need: A service needs to replay historical event notifications after a downstream subscriber defect is corrected. It does not replace either required solution in A or B. EventBridge archives support bounded replay of previously captured events; verify the two stated requirements independently rather than accepting an unrelated change.

E:

This action targets a different technical need: Finance needs engineering costs apportioned by team using tags rather than guessed from account totals. It does not replace either required solution in A or B. Cost allocation tags must be activated before they appear in billing cost analytics; verify the two stated requirements independently rather than accepting an unrelated change.

Question 241

For the enterprise requirement "A service needs to replay historical event notifications after a downstream subscriber defect is corrected", the team implemented this change: Enable EventBridge event-bus archive and replay for eligible matching events. Which observation should be required before the change is approved?

  1. A synthetic endpoint failure directs new DNS resolutions to the secondary healthy stack within the planned TTL behavior
  2. Writes in either Region replicate to the other and conflict handling matches the business design
  3. A synthetic or observed unusual cost pattern appears in anomaly alerts with impacted spend drivers
  4. The selected time window can be replayed to the target bus without inventing events that were never archived

Explanation

Correct Answer

D:

This measures the behavior required by the specific solution, rather than simply checking that it was configured. EventBridge archives support bounded replay of previously captured events. The acceptance condition is linked directly to the scenario: A service needs to replay historical event notifications after a downstream subscriber defect is corrected.

Incorrect Answers

A:

A synthetic endpoint failure directs new DNS resolutions to the secondary healthy stack within the planned TTL behavior. However, this does not establish the required outcome: the selected time window can be replayed to the target bus without inventing events that were never archived.

B:

Writes in either Region replicate to the other and conflict handling matches the business design. However, this does not establish the required outcome: the selected time window can be replayed to the target bus without inventing events that were never archived.

C:

A synthetic or observed unusual cost pattern appears in anomaly alerts with impacted spend drivers. However, this does not establish the required outcome: the selected time window can be replayed to the target bus without inventing events that were never archived.

Question 242

An enterprise architecture team faces this design requirement: Compliance requires protected organization-wide API activity logs to flow into a centralized security account with controlled deletion. Which selection is defensible under the given constraints?

  1. Deploy organization-managed AWS Config rules and targeted auto-remediation through approved Systems Manager Automation
  2. Use S3 Storage Lens metrics to identify expensive bucket-level and organization-wide storage trends
  3. Use AWS Private CA to issue private certificates with a managed trust chain and documented renewal
  4. Configure an organization trail delivered to a protected central S3 bucket with appropriate key and bucket controls

Explanation

Correct Answer

D:

AWS Organizations trails centralize multi-account CloudTrail logging when storage access is secured. The required architecture outcome is: Compliance requires protected organization-wide API activity logs to flow into a centralized security account with controlled deletion. Validate this choice by checking that Every enrolled account produces expected trail events in the security account and workloads cannot delete retained logs.

Incorrect Answers

A:

Per-account one-off inspections do not continuously evaluate drift across accounts. The specific problem here is that disjoint local-account trails leave central auditors with incomplete visibility.

B:

Teams have only aggregate bills and cannot locate the source of inefficient storage usage. The specific problem here is that disjoint local-account trails leave central auditors with incomplete visibility.

C:

Public ACM-issued certificates were wrongly assumed to provide a corporate private CA chain. The specific problem here is that disjoint local-account trails leave central auditors with incomplete visibility.

Question 243

A deployed environment still does not meet the original requirement: A global TCP service wants static public entry addresses and traffic steering over the AWS global network for lowest path latency. What explains why the stated requirement was not met?

  1. The team assumes an x86 machine image and native binaries can run unchanged on arm64
  2. Unbounded request bursts overload backends because no gateway rate protection is configured
  3. Region-specific public IPs and DNS routing do not provide the needed global anycast transport optimization
  4. Every static asset fetch goes to a distant origin instead of the edge cache

Explanation

Correct Answer

C:

This is the technical design error aligned with the unmet requirement. Global Accelerator accelerates supported TCP/UDP applications without serving as an HTTP content cache. The appropriate correction is: Configure Global Accelerator listeners and healthy regional ALB or NLB endpoints. The control should then be tested by verifying that Clients use accelerator anycast addresses and connect to the healthy regional endpoint with improved path latency.

Incorrect Answers

A:

The team assumes an x86 machine image and native binaries can run unchanged on arm64. The stated evidence instead indicates: Region-specific public IPs and DNS routing do not provide the needed global anycast transport optimization.

B:

Unbounded request bursts overload backends because no gateway rate protection is configured. The stated evidence instead indicates: Region-specific public IPs and DNS routing do not provide the needed global anycast transport optimization.

D:

Every static asset fetch goes to a distant origin instead of the edge cache. The stated evidence instead indicates: Region-specific public IPs and DNS routing do not provide the needed global anycast transport optimization.

Question 244

An architecture review recommends this solution: Activate standardized cost allocation tags and enforce tagging through governance processes. The motivating situation is: Finance needs engineering costs apportioned by team using tags rather than guessed from account totals. Which statement explains why the recommendation solves the specific problem?

  1. Compute Optimizer uses resource metrics and recommendations but must be checked against workload SLOs
  2. Organization-level Config rules continuously evaluate configuration and can launch controlled remediations
  3. Compute Savings Plans apply eligible usage discounts across supported services and configurations
  4. Cost allocation tags must be activated before they appear in billing cost analytics

Explanation

Correct Answer

D:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Activate standardized cost allocation tags and enforce tagging through governance processes. The expected supporting evidence is: Cost and Usage Reports or Cost Explorer show tagged team spend after activation and reporting delay.

Incorrect Answers

A:

Instances were resized from average CPU alone despite memory or traffic constraints. The stated evidence instead indicates: Resource tags were never activated as billing cost allocation dimensions.

B:

Per-account one-off inspections do not continuously evaluate drift across accounts. The stated evidence instead indicates: Resource tags were never activated as billing cost allocation dimensions.

C:

On-demand usage was left wholly uncommitted despite predictable baseline compute consumption. The stated evidence instead indicates: Resource tags were never activated as billing cost allocation dimensions.

Question 245

An enterprise architecture team faces this design requirement: A message-processing application still uses an on-premises ActiveMQ-compatible broker and cannot immediately rewrite producers. Which selection is defensible under the given constraints?

  1. Evaluate Amazon MQ with an appropriate compatible engine and migrate broker connections in stages
  2. Capture resources in versioned CloudFormation or CDK definitions and deploy through reviewed pipelines
  3. Redesign notifications into event-driven processing using EventBridge or SQS with idempotent consumers
  4. Deploy a supported EKS architecture with managed control plane and appropriate node or Fargate capacity

Explanation

Correct Answer

A:

Amazon MQ can support compatible managed message brokers when protocol continuity matters. The required architecture outcome is: A message-processing application still uses an on-premises ActiveMQ-compatible broker and cannot immediately rewrite producers. Validate this choice by checking that Existing clients publish and consume messages with acceptable protocol compatibility after controlled cutover.

Incorrect Answers

B:

Console changes have no reproducible declarative infrastructure state. The specific problem here is that developers assume SQS has identical JMS or broker feature semantics to the source stack.

C:

Tight synchronous coupling propagates a noncritical downstream failure to the primary transaction. The specific problem here is that developers assume SQS has identical JMS or broker feature semantics to the source stack.

D:

A non-Kubernetes orchestrator was chosen despite strict Kubernetes extension compatibility requirements. The specific problem here is that developers assume SQS has identical JMS or broker feature semantics to the source stack.

Question 246

For the enterprise requirement "A proprietary virtual appliance cannot run on AWS-supported instance drivers without vendor modifications", the team implemented this change: Validate platform, hypervisor and kernel compatibility before committing to a target deployment. Which evidence confirms the intended behavior under test?

  1. A fresh environment can be recreated from code with predictable parameters and drift checks
  2. The proposed target design has documented permitted license use and tracked license utilization
  3. Vendor-certified testing proves that the appliance runs on the selected target or requires retain/replace decision
  4. A conversion report identifies unsupported objects and a pilot executes critical queries correctly

Explanation

Correct Answer

C:

This measures the behavior required by the specific solution, rather than simply checking that it was configured. Platform migration viability depends on software support and hardware or driver compatibility. The acceptance condition is linked directly to the scenario: A proprietary virtual appliance cannot run on AWS-supported instance drivers without vendor modifications.

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: vendor-certified testing proves that the appliance runs on the selected target or requires retain/replace decision.

B:

The proposed target design has documented permitted license use and tracked license utilization. However, this does not establish the required outcome: vendor-certified testing proves that the appliance runs on the selected target or requires retain/replace decision.

D:

A conversion report identifies unsupported objects and a pilot executes critical queries correctly. However, this does not establish the required outcome: vendor-certified testing proves that the appliance runs on the selected target or requires retain/replace decision.

Question 247

A professional architect is reviewing two independent workstreams. Requirement A: An Application Load Balancer intermittently forwards traffic to unhealthy containers after their readiness endpoint fails. Requirement B: Finance collects optimizer suggestions from Compute Optimizer, Trusted Advisor and cost dashboards but counts the same recommendation more than once. Choose TWO remedies that meet A and B respectively.

  1. Correct target group health checks and deployment deregistration timing based on actual readiness semantics
  2. Use Cost Optimization Hub for supported consolidated recommendations and track deduplicated savings
  3. Review RI utilization, supported reservation sharing and regional family coverage before buying more
  4. Introduce a blue-green deployment strategy with health alarms and traffic rollback
  5. Enable AWS WAF logging to an appropriate destination with sensitive-data handling and analyze matched rules

Explanation

Correct Answers

A:

This action meets the independently stated requirement A: An Application Load Balancer intermittently forwards traffic to unhealthy containers after their readiness endpoint fails. Load balancer health checks must match actual application readiness rather than superficial liveness. A direct acceptance check is: Unhealthy containers leave active target selection promptly while healthy targets continue receiving requests.

B:

This action meets the independently stated requirement B: Finance collects optimizer suggestions from Compute Optimizer, Trusted Advisor and cost dashboards but counts the same recommendation more than once. Consolidated savings recommendations should not be summed blindly across sources. A direct acceptance check is: Finance reports one adjusted opportunity per overlapping recommendation source.

Incorrect Answers

C:

This action targets a different technical need: Several member accounts buy overlapping Reserved Instances, yet unused reservations remain in the organization. It does not replace either required solution in A or B. RI coverage should be evaluated at consolidated billing scope where sharing is enabled; verify the two stated requirements independently rather than accepting an unrelated change.

D:

This action targets a different technical need: A production deployment causes an outage because all old tasks were removed before new code passed tests. It does not replace either required solution in A or B. Blue-green promotion protects a known-good environment until replacement quality is established; verify the two stated requirements independently rather than accepting an unrelated change.

E:

This action targets a different technical need: Attackers continuously probe application URLs and security needs request-level evidence for rule tuning. It does not replace either required solution in A or B. WAF logs provide request and rule evaluation evidence for security tuning; verify the two stated requirements independently rather than accepting an unrelated change.

Question 248

A deployed environment still does not meet the original requirement: A public application must divert DNS traffic away from an endpoint when health checks show it has failed. Which underlying cause should be investigated first?

  1. DNS simple routing cannot automatically reflect the application's health
  2. Unbounded request bursts overload backends because no gateway rate protection is configured
  3. Independent release scripts lack enforceable promotion ordering and approval evidence
  4. Imperative glue retries all upstream steps and creates duplicate side effects

Explanation

Correct Answer

A:

This is the technical design error aligned with the unmet requirement. DNS failover requires health-aware routing and realistic expectations for cached answers. The appropriate correction is: Configure Route 53 failover routing with suitable health checks and a tested secondary target. The control should then be tested by verifying that New DNS lookups return the secondary endpoint after a primary health check changes to unhealthy.

Incorrect Answers

B:

Unbounded request bursts overload backends because no gateway rate protection is configured. The stated evidence instead indicates: DNS simple routing cannot automatically reflect the application's health.

C:

Independent release scripts lack enforceable promotion ordering and approval evidence. The stated evidence instead indicates: DNS simple routing cannot automatically reflect the application's health.

D:

Imperative glue retries all upstream steps and creates duplicate side effects. The stated evidence instead indicates: DNS simple routing cannot automatically reflect the application's health.

Question 249

A deployed environment still does not meet the original requirement: A shared EFS file system slows a data-processing batch even though compute workers are mostly idle. Which underlying cause should be investigated first?

  1. The service relies solely on application code with no rate-based edge filtering
  2. Read-only analytical traffic saturates the production database's single writable instance
  3. The shared file system's throughput mode or credit availability constrains parallel clients
  4. Stream shard limits or skewed partition keys cannot handle incoming record throughput

Explanation

Correct Answer

C:

This is the technical design error aligned with the unmet requirement. EFS throughput characteristics must match concurrent IO patterns and required sustained rate. The appropriate correction is: Evaluate EFS throughput and performance modes and provision an appropriate supported throughput setting. The control should then be tested by verifying that File-system throughput reaches target under representative concurrent processing without exhausted credits.

Incorrect Answers

A:

The service relies solely on application code with no rate-based edge filtering. The stated evidence instead indicates: The shared file system's throughput mode or credit availability constrains parallel clients.

B:

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.

D:

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.

Question 250

An enterprise architecture team faces this design requirement: A global enterprise wants a portfolio-level view of application migrations, owners, blockers and cutover states. What should the solutions architect recommend?

  1. Perform application dependency discovery and group connected workloads into migration waves
  2. Modernize to an appropriately configured Amazon Aurora cluster with multi-AZ storage and tested failover
  3. Track AWS Transform migration wave and server states, and maintain centrally owned application milestones, blockers and cutover decisions
  4. Assess schema, procedural conversion complexity and application query compatibility using suitable database migration assessment tools

Explanation

Correct Answer

C:

A centralized migration tracking layer supports coordination across application teams. The required architecture outcome is: A global enterprise wants a portfolio-level view of application migrations, owners, blockers and cutover states. Validate this choice by checking that Owners can trace migration milestones and blockers for each workload without conflicting local spreadsheets.

Incorrect Answers

A:

Application lists omit runtime call dependencies and produce broken split-wave migrations. The specific problem here is that migration tasks are tracked in separate team documents with no common portfolio state.

B:

Application reliability still depends on one unmanaged database host and manual restores. The specific problem here is that migration tasks are tracked in separate team documents with no common portfolio state.

D:

Database engine migration was assumed to be a simple homogeneous replication job. The specific problem here is that migration tasks are tracked in separate team documents with no common portfolio state.
