Question 1

Southridge Video is changing its data lake platform as part of a migration wave planning session. Which AWS approach best enables the team to turn utilization data into an actionable cleanup and rightsizing backlog while using measurable evidence before and after remediation? The current estate includes 6 AWS accounts and active workloads in eu-west-1 and eu-central-1. Assume all unspecified components already meet their requirements.

  1. Treat service quotas as reliability dependencies: monitor headroom, request increases early, and test recovery capacity in the target environment
  2. Use Cost Explorer, Compute Optimizer, Trusted Advisor, and service inventory data to identify idle or overprovisioned resources, then remove or rightsize them safely
  3. Analyze the stable post-rightsizing usage baseline, then purchase the commitment model that matches flexibility and term requirements
  4. Use Systems Manager Patch Manager or managed-service patching and policy-based backup services with compliance reporting and restore validation

Correct answer: B

Why: Cost optimization begins by measuring utilization and identifying resources whose size or existence is not justified by workload demand. This directly addresses the primary requirement and remains appropriate while using measurable evidence before and after remediation.

Option review:

A: A redundant design is not reliable if quotas prevent it from scaling or failing over when needed. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to turn utilization data into an actionable cleanup and rightsizing backlog under the additional constraint of while using measurable evidence before and after remediation.

B: Cost optimization begins by measuring utilization and identifying resources whose size or existence is not justified by workload demand. This directly addresses the primary requirement and remains appropriate while using measurable evidence before and after remediation.

C: Commitments are most effective after rightsizing and when the organization understands which usage is predictably sustained. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to turn utilization data into an actionable cleanup and rightsizing backlog under the additional constraint of while using measurable evidence before and after remediation.

D: Patching and backups need defined schedules, scope, compliance evidence, isolation, and testing to be dependable security controls. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to turn utilization data into an actionable cleanup and rightsizing backlog under the additional constraint of while using measurable evidence before and after remediation.

Learning point: Use Cost Explorer, Compute Optimizer, Trusted Advisor, and service inventory data to identify idle or overprovisioned resources, then remove or rightsize them safely. Cost optimization begins by measuring utilization and identifying resources whose size or existence is not justified by workload demand. In this variant, the decision also has to work while using measurable evidence before and after remediation.

Question 2

An architecture board at Woodgrove Bank asks the principal solutions architect to avoid purchasing commitments for transient or interruption-tolerant workloads that do not have a stable baseline while using measurable evidence before and after remediation for a customer-facing API. Which recommendation is most appropriate? The current estate includes 13 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.

  1. Use centralized CloudWatch observability with actionable alarms and event-driven or Systems Manager automation for known remediation paths
  2. Test changes against performance and cost objectives using representative traffic, then adopt only changes that preserve required service levels
  3. Use observed growth trends to add replication, load balancing, and Auto Scaling or managed elastic features that can replace failed capacity
  4. Analyze the stable post-rightsizing usage baseline, then purchase the commitment model that matches flexibility and term requirements

Correct answer: D

Why: Commitments are most effective after rightsizing and when the organization understands which usage is predictably sustained. This directly addresses the primary requirement and remains appropriate while using measurable evidence before and after remediation.

Option review:

A: Monitoring should produce useful signals and, where safe, trigger repeatable remediation instead of relying on manual observation of every component. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to avoid purchasing commitments for transient or interruption-tolerant workloads that do not have a stable baseline under the additional constraint of while using measurable evidence before and after remediation.

B: Optimization should be validated against the workload objectives so savings or speed improvements do not create new reliability or performance problems. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to avoid purchasing commitments for transient or interruption-tolerant workloads that do not have a stable baseline under the additional constraint of while using measurable evidence before and after remediation.

C: Growth planning should combine replication and elastic scaling so the system maintains capacity and recovers automatically as demand changes. This can be valid in another AWS architecture context, but it does not most directly satisfy the primary requirement to avoid purchasing commitments for transient or interruption-tolerant workloads that do not have a stable baseline under the additional constraint of while using measurable evidence before and after remediation.

D: Commitments are most effective after rightsizing and when the organization understands which usage is predictably sustained. This directly addresses the primary requirement and remains appropriate while using measurable evidence before and after remediation.

Learning point: Analyze the stable post-rightsizing usage baseline, then purchase the commitment model that matches flexibility and term requirements.

Question 14

During a post-incident architecture review at Alpine Sports, the security architect is designing a customer-facing API. The requirement is to avoid purchasing commitments for transient or interruption-tolerant workloads that do not have a stable baseline while reducing repetitive manual operations.
