AWS Certified Advanced Networking – Specialty (ANS-C01)Network Management and OperationsMedium
A company is using AWS Transit Gateway to connect over 100 VPCs across multiple AWS Regions. The network operations team frequently needs to troubleshoot routing issues and ensure that traffic between specific source and destination VPCs traverses the expected path. Manually inspecting route tables for each VPC and Transit Gateway attachment is becoming unmanageable and error-prone. Which AWS Network Manager feature can automate the validation of network paths across this complex environment?
- ANetwork Manager Global Network Dashboard.
- BNetwork Manager Events and Alarms.
- CNetwork Manager Route Analyzer.
- DNetwork Manager Insights.
Show answer & explanationAnswer & explanation
Correct answer: C. Network Manager Route Analyzer.
AWS Network Manager's Route Analyzer is specifically designed to simulate and analyze network paths between a source and a destination within a global network, including Transit Gateway attachments and VPCs. It verifies that traffic follows the expected routes and helps identify misconfigurations or unexpected routing behavior, making it ideal for large-scale Transit Gateway environments.
Why the other options are wrong
- A. The Global Network Dashboard provides a high-level overview of the global network but does not offer detailed path analysis.
- B. Events and Alarms notify about changes or issues but don't perform proactive route validation or analysis.
- D. Network Manager Insights provides aggregated operational data and trends but not granular, hop-by-hop path validation.
Network Manager Route Analyzer
An AWS Network Manager feature that simulates and analyzes network paths within a global network, including Transit Gateway, to validate routing and identify misconfigurations.
- Simulates network paths.
- Verifies expected routing.
- Crucial for complex TGW environments.
Memory trick: For TGW routes, the Route Analyzer shows the true path.
