Nutanix Certified Professional – Multicloud Infrastructure v6.5 (NCP-MCI) — Question 14

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?

Answer options

• A. One of the network interfaces has a bad patch cable
• B. Portfast is not enabled on the switch ports
• C. Switch ports are configured with different VLANs
• D. This is normal behavior for LAN Failover

Correct answer: C

Explanation

The correct answer is C because if the switch ports are configured with different VLANs, it would prevent communication between the guest VMs and the hypervisor when one interface is disconnected. Option A suggests a bad cable, which would not explain the differing behavior between interfaces. Option B's mention of Portfast is irrelevant to the issue at hand, and Option D incorrectly states that this is expected behavior when it is not.
