AWS Certified Cloud Practitioner — Question 594

Which AWS service or feature is used to troubleshoot network connectivity issues between Amazon EC2 instances?

Answer options

• A. AWS Certificate Manager (ACM)
• B. Internet gateway
• C. VPC Flow Logs
• D. AWS CloudHSM

Correct answer: C

Explanation

VPC Flow Logs captures detailed information about IP traffic entering and leaving network interfaces within your VPC, which is essential for diagnosing network connectivity issues between Amazon EC2 instances. AWS Certificate Manager (ACM) is used for managing SSL/TLS certificates, an Internet gateway provides a path for internet traffic, and AWS CloudHSM offers secure cryptographic key storage, making them incorrect for network troubleshooting.
