Question #: 69
Topic #: 4

[All Nutanix Certified Services Core Infrastructure Professional Questions]

A consultant is unable to ping the CVM from the hypervisor using the external interface. The customer's network is configured with the 10.3.12.0/24 subnet without VLAN tagging. The CVM and hypervisor are using the same address space.

What is causing this issue?

AThe 1GbE and 10GbE NICs have not been separated.

BThe default gateway is incorrect.

CThe switch is trunked without a native VLAN.

DThe CVM/hypervisor only communicates over 192.168.5.0/24.

Show Suggested Answer

Suggested Answer: B

If a consultant is unable to ping the CVM from the hypervisor using the external interface in a network without VLAN tagging, and both are using the same subnet, the issue might be related to an incorrect default gateway configuration. The default gateway must be correctly set to ensure proper routing of packets between the CVM and the hypervisor. An incorrect gateway can prevent successful communication even if both devices are on the same subnet. Reference:

Ooh, I bet the 1GbE and 10GbE NICs haven't been separated. That's like trying to fit a square peg in a round hole, am I right?

Hold on, did someone forget to pay the internet bill? The CVM and hypervisor only communicating over 192.168.5.0/24 sounds like a classic case of network isolation.

Hmm, the switch being trunked without a native VLAN sounds like the culprit to me. No VLAN tagging means the packets might be getting dropped.

User 1: I think the switch being trunked without a native VLAN is causing the issue.

Actually, I believe the switch being trunked without a native VLAN could also be causing the issue.

I agree with Felicidad, the default gateway could be the problem.

I'm not sure about that. The question clearly states that the CVM and hypervisor are using the same address space, so the default gateway shouldn't be the problem.
