Nutanix NCS-Core image Question 53 82023 09232024013105000000

A Nutanix host is connected as shown in the exhibit with br0-up set to active/backup. Physical Switch 1 experiences a power outage causing br0-up to failover to using eth2. The CVM and host become inaccessible. User VMs restart on other hosts in the cluster, which causes a disruption to those VMs.

Which configuration issue likely caused this outage?

Bridge br0-up should be configured to use balance-tcp rather than active/backup.
