Question 34

An administrator is performing validation testing of a newly deployed cluster. During this test, the administrator disconnects each LAN interface from each of the nodes while pinging the hypervisor and guest VMs.

When the first interface is disconnected, pings continue as expected to the hypervisor, but pings stop responding from the guest. Pings continue when the interface is reconnected. When the second interface is disconnected, pings continue to both the hypervisor and guest VMs.

What could be the cause of this error?

    Correct Answer: C

    In this scenario, when the first interface is disconnected, the hypervisor continues to respond to pings, but the guest VMs do not. This behavior suggests that there might be an issue with the network configuration related to VLANs. If the switch ports to which the network interfaces are connected are configured with different VLANs, it would cause the guest VMs in one VLAN to become unreachable when the respective interface is disconnected. The hypervisor, having access to all VLANs, would remain responsive, explaining the observed behavior. Thus, the most likely cause of this issue is that the switch ports are configured with different VLANs.

. Switch ports are configured with different VLANs

JustinS1234Option: C

The behavior described in the scenario is not normal for LAN failover. In a properly configured LAN failover setup, the guest VMs should continue to respond to pings even when one interface is disconnected, as the traffic should be rerouted through the remaining active interfaces. Given the options, the most likely cause of this issue is C. Switch ports are configured with different VLANs. If the two network interfaces are connected to switch ports configured with different VLANs, then disconnecting one interface could cause the guest VMs in one VLAN to become unreachable. This would explain why pings to the hypervisor continue (as it may have access to all VLANs), but pings to the guest VMs stop when one interface is disconnected.
