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?
A is correct
should be C https://cloud.google.com/network-connectivity/docs/router/support/troubleshoot-bgp-routes#check-quotas-and-limits
You need to use metric dynamic_routes/learned_routes/unique_destinations_limit, since that indicates what the limit is.
C any_dropped_unique_destinations Indicates whether this VPC network has any destinations dropped due to exceeding one or both of the route quotas.
