AWS Certified Advanced Networking – Specialty (ANS-C01)Network Management and OperationsHard
A large enterprise uses AWS Transit Gateway to interconnect hundreds of VPCs. The network operations team frequently needs to troubleshoot routing issues and verify network paths between specific EC2 instances in different VPCs. Manually inspecting Transit Gateway route tables and VPC route tables for each connection path is time-consuming and error-prone. Which AWS Network Manager feature can simplify this task?
- AGlobal Network View
- BPerformance Monitoring
- CEvents and Notifications
- DRoute Analyzer
Show answer & explanationAnswer & explanation
Correct answer: D. Route Analyzer
AWS Network Manager's Route Analyzer feature is specifically designed to simplify troubleshooting network paths. It allows you to specify a source and destination (e.g., an EC2 instance in one VPC to an EC2 instance in another) and then visualizes the complete network path, including all Transit Gateway attachments, route tables, and security group rules, helping to identify routing issues or misconfigurations.
Why the other options are wrong
- A. Global Network View provides a high-level topology map of your network, but not a granular, step-by-step path analysis for troubleshooting specific routing issues.
- B. Performance Monitoring provides metrics like latency and packet loss, not a detailed path analysis for routing.
- C. Events and Notifications inform about network changes or issues but don't provide a tool for interactive path analysis.
Network Manager Route Analyzer
A feature within AWS Network Manager that helps troubleshoot network connectivity by tracing and visualizing the network path between specified source and destination endpoints.
- Analyzes paths across VPCs, Transit Gateways, and on-premises connections.
- Identifies routing issues, security group blocks, and network ACL conflicts.
- Provides a visual representation of the network flow.
Memory trick: To 'analyze' your 'route' through the network, use 'Route Analyzer'.
