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
✓
Amazon CloudWatch
CloudWatch provides metrics for EBS volumes including read/write throughput and IOPS, which can be used to analyze disk I/O performance. Option A (AWS Trusted Advisor) is wrong because it provides best-practice checks but not real-time performance analysis. Option B (AWS Config) is wrong because it tracks configuration changes, not performance. Option C is correct. Option D is a duplicate of Option B and is also wrong for the same reason.
