Question
An administrator has recently configured HA on a cluster. After reviewing the summary tab on one of the hosts, the warning in Exhibit 1 is displayed:
The administrator proceeds to view the management network port group data shown in Exhibit 2:
The administrator then views the management network vSwitch as shown in Exhibit 3:
Based on the exhibits, which two steps should be taken to ensure redundancy on the management network? (Choose two.)
Exhibit
Options
- AMove vmnic1 to Standby adapters.
- BAdd an additional vmknic to the Network Adapters and move it to Active adapters.
- CSet the advanced HA configuration parameter das.ignoreRedundantNetWarning to True.
- DUncheck the Override Failover Checkbox on the management network port group.

Why each option
vSphere HA requires a redundant management network, and the correct fix is to add vmnic1 as a Standby adapter and remove the port-group-level NIC teaming override so the vSwitch policy applies.
Moving vmnic1 to Standby adapters on the management network port group provides a failover NIC so that if the active uplink fails, HA heartbeating continues, directly addressing the redundancy warning.
Adding an additional vmknic moves a VMkernel adapter, not a physical NIC uplink; management network redundancy requires physical uplink (vmnic) redundancy, not additional VMkernel interfaces.
Setting das.ignoreRedundantNetWarning to True suppresses the warning message but does not actually configure redundancy, leaving the management network still vulnerable to a single point of failure.
Unchecking the Override Failover Checkbox on the management network port group causes it to inherit the vSwitch-level NIC teaming policy, which includes both Active and Standby adapters, restoring redundancy without requiring a separate per-port-group configuration.
