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.

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

Question 18

During a cost optimization workshop at Blue Yonder Airlines, the security architect is designing a global web application. The requirement is to exercise recovery actions before an actual outage exposes missing dependencies while retaining AWS-native traceability for the change. Which architecture is the best fit? The current estate includes 11 AWS accounts and active workloads in us-east-1 and us-west-2. Prefer an AWS-managed capability when it meets the requirements with less operational overhead.

Use Systems Manager or service-native configuration automation, and run controlled failure scenarios to validate recovery procedures
Analyze the stable post-rightsizing usage baseline, then purchase the commitment model that matches flexibility and term requirements
Benchmark candidate instance families or scaling designs under representative load, then rightsize using observed CPU, memory, network, and storage characteristics
Use Systems Manager Patch Manager or managed-service patching and policy-based backup services with compliance reporting and restore validation

Correct answer: A

Option review:
