Nutanix Certified Professional – Multicloud Infrastructure v6.5 (NCP-MCI) — Question 64

An administrator has created a Nutanix managed network, and assigned it a VLAN ID of 512.
Several VMs have been created, and the administrator notices that the VMs can successfully communicate with other VMs on that VLAN, provided they are on the same host, but cannot communicate with VMs that reside on different hosts in the cluster.
What is most likely the cause of this issue?

Answer options

• A. There is a firewall rule blocking VLAN512 traffic.
• B. The VLAN was not created on the upstream switches.
• C. The administrator did not create the VLAN on all hosts.
• D. VLAN512 is a reserved VLAN ID, and not usable for guest VMs.

Correct answer: B

Explanation

The correct answer is B because if the VLAN is not configured on the upstream switches, the VMs will not be able to communicate across different hosts. Option A is incorrect as there is no indication of a firewall rule. Option C is not the issue since VLANs typically need to be created on the switches rather than on each host. Option D is incorrect because VLAN512 can be used if properly configured.
