AWS Certified Advanced Networking – Specialty (ANS-C01)Network Management and OperationsHard
A global company uses AWS Transit Gateway to connect multiple VPCs across several AWS Regions. They need to analyze network performance and identify potential bottlenecks for cross-region traffic. The solution must provide detailed visibility into latency, packet loss, and throughput between attachments. Which AWS service or feature provides this functionality?
- AAWS Global Accelerator
- BVPC Flow Logs for Transit Gateway
- CAmazon CloudWatch Metrics for Transit Gateway
- DAWS Network Manager's Performance Monitoring
Show answer & explanationAnswer & explanation
Correct answer: D. AWS Network Manager's Performance Monitoring
AWS Network Manager, specifically its Performance Monitoring feature, is designed to provide detailed insights into the performance of Transit Gateway connections, including latency, packet loss, and throughput, across global networks. While Flow Logs provide traffic details and CloudWatch provides basic metrics, Network Manager offers a comprehensive view of global network performance.
Why the other options are wrong
- A. AWS Global Accelerator improves application availability and performance by routing traffic through the AWS global network, but it's not a monitoring service for existing Transit Gateway performance.
- B. VPC Flow Logs for Transit Gateway provide traffic flow records, but not direct performance metrics like latency or packet loss across regions.
- C. CloudWatch Metrics for Transit Gateway offer basic metrics (e.g., bytes in/out) but lack the deep performance analysis capabilities for cross-region latency and packet loss that Network Manager provides.
AWS Network Manager Performance Monitoring
A feature within AWS Network Manager that provides visibility into the performance of your global network hosted on AWS, including Transit Gateways.
- Measures latency, jitter, packet loss, and throughput between network attachments.
- Helps identify performance bottlenecks and optimize network design.
- Visualizes network performance data on a global map.
Memory trick: To 'manage' global network 'performance,' use 'Network Manager.'
