An administrator is troubleshooting an issue where workloads connected to a Tier-1 Gateway named T1-App can no longer reach external North/South destinations. The Tier-1 is connected to an Active/Standby Tier-0 Gateway named T0-Prod. Symptoms observed:VMs on segments attached to T1-App can ping each other.VMs on T1-App cannot reach any external IP outside T0-Prod. From a VM on the segment, ping to the T1-App Distributed Router (DR) IP succeeds. Ping from the VM to the T1-App Service Router (SR) fails. The Edge cluster hosting the T1-App SR shows both Edge nodes Up and Healthy. No failover has occurred - the same Edge node is still shown as Active for T1-App. What is the most likely cause of this issue?

1. A. The overlay network between DR and SR has an MTU mismatch. — đáp án hiện tại
2. B. Localized control plane is enabled on the Tier-1 causing the SR to remain admin-down.
3. C. Route advertisement from T1-App to T0-Prod for 100.64.x.x/31 is disabled.
4. D. Static default route is missing on the Tier-1 DR component.
