Topic 1 Question 177
2 つ選択You have provisioned a Cloud Interconnect connection with a VLAN attachment. You configured Border Gateway Protocol (BGP) between your on-premises router and your Cloud Router. After deploying and testing the connection, you discover that the BGP session is not established between your on-premises router and the Cloud Router. Which two actions should you take to resolve this issue?
From the Google Cloud console, run gcloud compute routers get-status
to verify the Address Resolution Protocol (ARP) learned. Verify that you have configured the on-premises router's subinterface with a subnet mask of /31.
Verify that you have configured the on-premises router's eBGP multihop with a minimum hop length of 4.
Verify that you have configured the on-premises router's BGP security parameters to use MD5 authentication.
From the Google Cloud console, run gcloud compute interconnects get-diagnostics
to verify the Address Resolution Protocol (ARP) learned.

- 正解だと思う選択肢: AB
(A) gcloud compute routers get-status → This command helps troubleshoot BGP session issues by showing ARP information, learned prefixes, and BGP status. If ARP isn't learned correctly, BGP won't establish.
(B) Subnet mask of /31 → Google Cloud uses a /30 or /31 subnet for VLAN attachments. If your on-premises router isn't configured correctly with one of these subnet masks, BGP won't work.
