A network engineer is troubleshooting high latency between two EC2 instances in the same VPC but different Availability Zones. Which AWS service can provide detailed network performance metrics to identify the source of latency?
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
✓
AWS X-Ray
Correct answer: C. AWS X-Ray provides end-to-end tracing and can capture network latency between services, including EC2 instances. It can help identify where delays occur. Option A (AWS Config) is incorrect because it monitors configuration changes, not performance. Option B (AWS CloudTrail) is incorrect because it records API calls for auditing, not network metrics. Option D (VPC Flow Logs) is incorrect because it captures IP traffic metadata (packet-level) but does not provide latency or performance metrics.
