VCP-DCV Configure and Manage vSphere Networking Practice Question
A company has a single ESXi host with a standard switch. The administrator creates a new port group for a DMZ network and assigns a VM to it. The VM cannot ping the default gateway. The physical switch port is configured as a trunk with VLAN 100 allowed. The port group VLAN ID is set to 100. The physical NIC is connected to the switch port and shows link up. What should the administrator do to resolve the issue?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Verify the VM's IP configuration
The physical and virtual networking configurations appear correct (VLAN 100 on both sides, link up), so the issue is likely an IP misconfiguration on the VM itself. Option A (enable VLAN tagging on the physical switch port) is unnecessary as the port group already tags VLAN 100. Option B (change VLAN ID to 0) would break connectivity. Option D (add a second physical NIC to the standard switch) does not address the connectivity problem.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable VLAN tagging on the physical switch port
Why it's wrong here
The physical switch port is already configured as a trunk, so VLAN tagging is already enabled.
- ✗
Change the VLAN ID to 0
Why it's wrong here
Setting VLAN ID to 0 would remove VLAN tagging, causing mismatch with the physical switch trunk.
- ✓
Verify the VM's IP configuration
Why this is correct
If the gateway IP, subnet mask, or default gateway is misconfigured, the VM cannot ping the gateway despite correct VLAN settings.
- ✗
Add a second physical NIC to the standard switch
Why it's wrong here
Adding a NIC does not fix the existing connectivity issue; it would only provide redundancy.
