AWS Certified Advanced Networking – Specialty (ANS-C01) — Question 256

A company runs an application across multiple AWS Regions and multiple Availability Zones. The company needs to expand to a new AWS Region. Low latency is critical to the functionality of the application.

A network engineer needs to gather metrics for the latency between the existing. Regions and the new Region. The network engineer must gather metrics for at least the previous 30 days.

Which solution will meet these requirements?

Answer options

• A. Configure an AWS Network Access Analyzer Network Access Scope, and use the analysis to review the latency.
• B. Set up AWS Network Manager Infrastructure Performance. Publish network performance metrics to Amazon CloudWatch.
• C. Use an Amazon VPC Reachability Analyzer path to review the latency.
• D. Set up VPC Flow Logs. Publish log metrics to Amazon CloudWatch.

Correct answer: B

Explanation

The correct answer is B because AWS Network Manager Infrastructure Performance provides detailed insights into network performance, including latency, and can track metrics over time for more than 30 days. Options A, C, and D do not provide the necessary long-term metrics specifically focused on latency across Regions.
