- A
Enable detailed billing reports and analyze costs.
Why wrong: Shows costs but does not identify which snapshots are unused.
- B
Use the AWS CLI to list all snapshots and manually check each one.
Why wrong: Time-consuming and error-prone for hundreds.
- C
Use AWS Backup to manage snapshots and set retention rules.
AWS Backup can automate snapshot lifecycle and identify old snapshots.
- D

SAP-C02 Continuous Improvement for Existing Solutions Practice Question
This SAP-C02 practice question tests your understanding of continuous improvement for existing solutions. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company receives a Trusted Advisor recommendation to reduce costs by deleting unused Amazon EBS snapshots. The company has hundreds of snapshots. Which approach should the company use to identify and delete snapshots that are no longer needed?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use AWS Backup to manage snapshots and set retention rules.
Option C is correct because AWS Backup provides lifecycle policies and centralized snapshot management, making it easy to identify and automatically delete unused snapshots. Option A is incorrect because detailed billing reports show cost data but do not help identify which specific snapshots are unused. Option B is incorrect because manually checking each snapshot with the AWS CLI is not scalable for hundreds of snapshots. Option D is incorrect because Amazon S3 Lifecycle policies manage S3 objects, not EBS snapshots.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
