Question 1

While conducting a production readiness review, the cloud financial management lead at Trey Research needs to replace manual incident discovery with actionable metrics, logs, alarms, and automatic remediation for known failure modes while using measurable evidence before and after remediation. Which architecture decision best matches the stated constraints? The current estate includes 33 AWS accounts and active workloads in eu-west-1 and eu-central-1. The team wants the most direct architecture decision for this requirement.

  1. Perform a structured Well-Architected-style review using operational telemetry, security findings, and reliability evidence, then prioritize risks by business impact
  2. Use Systems Manager or service-native configuration automation, and run controlled failure scenarios to validate recovery procedures
  3. Use event-driven monitoring and approved automation runbooks for repeatable remediations, with logging, guardrails, and human approval where risk requires it
  4. Use centralized CloudWatch observability with actionable alarms and event-driven or Systems Manager automation for known remediation paths

Correct answer: D

Why: Monitoring should produce useful signals and, where safe, trigger repeatable remediation instead of relying on manual observation of every component. This directly addresses the primary requirement and remains appropriate while using measurable evidence before and after remediation.

Option review:

A: Continuous improvement is most effective when recommendations are grounded in measurable risk and workload evidence across multiple architectural dimensions. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to replace manual incident discovery with actionable metrics, logs, alarms, and automatic remediation for known failure modes under the additional constraint of while using measurable evidence before and after remediation.

B: Configuration automation reduces drift, while failure exercises reveal gaps in monitoring, dependencies, and operational recovery knowledge. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to replace manual incident discovery with actionable metrics, logs, alarms, and automatic remediation for known failure modes under the additional constraint of while using measurable evidence before and after remediation.

C: Automation is most valuable for well-understood recurring actions when it remains observable, controlled, and reversible. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to replace manual incident discovery with actionable metrics, logs, alarms, and automatic remediation for known failure modes under the additional constraint of while using measurable evidence before and after remediation.

D: Monitoring should produce useful signals and, where safe, trigger repeatable remediation instead of relying on manual observation of every component. This directly addresses the primary requirement and remains appropriate while using measurable evidence before and after remediation.

Learning point: Use centralized CloudWatch observability with actionable alarms and event-driven or Systems Manager automation for known remediation paths.

The requirement is to choose blue/green or rolling deployment based on rollback speed and capacity constraints while using measurable evidence before and after remediation. Which architecture is the best fit? The current estate includes 40 AWS accounts and active workloads in us-east-1 and us-west-2. The design must preserve security and auditability while meeting the stated objective.

  1. Define measurable KPIs/SLOs, instrument the relevant components, and use CloudWatch or service metrics to isolate the actual bottleneck before changing architecture
  2. Analyze the stable post-rightsizing usage baseline, then purchase the commitment model that matches flexibility and term requirements
  3. Adopt a deployment strategy with health checks, progressive exposure, and automated rollback that matches the application and capacity constraints
  4. Use observed growth trends to add replication, load balancing, and Auto Scaling or managed elastic features that can replace failed capacity

Correct answer: C

Why: Deployment improvements should reduce blast radius and make unhealthy releases detectable and reversible. This directly addresses the primary requirement and remains appropriate while using measurable evidence before and after remediation.

Option review:
