Google Cloud Professional Cloud Network Engineer — Question 178

Your company's cloud network has hybrid connectivity to an on-premises environment through Cloud Interconnect in two regions (us-east4 and us-west1). You received complaints that some on-premises destinations are no longer reachable from us-east4, after changes were made to advertise additional routes to us-west1. You need to troubleshoot to see if any routes were dropped. What should you do?

Answer options

• A. Query the dynamic_routes/learned_routes/dropped_unique_destinations metric and review the global routing_mode metric attribute.
• B. Query the dynamic_routes/learned_routes/unique_destinations_limit metric and review the global routing_mode metric attribute.
• C. Query the dynamic_routes/learned_routes/any_dropped_unique_destinations metric and review the regional routing_mode metric attribute.
• D. Query the dynamic_routes/learned_routes/dropped_unique_destinations metric and review the regional routing_mode metric attribute.

Correct answer: C

Explanation

The correct answer is C because it specifically focuses on any dropped unique destinations while considering the regional routing_mode, which is relevant to the troubleshooting context. Options A and B reference global routing_mode, which is not applicable for the issue at hand, and option D does not address the need to check for any dropped unique destinations.
