VCP-DCV Configure and Manage vSphere Networking Practice Question
A VM cannot connect to the network after being migrated to a different host in the cluster. The VM's network adapter is connected to a standard switch port group that exists on the source host but not on the destination host. What is the most likely cause?
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
✓
The standard switch is not configured on the destination host.
Standard switches are host-specific, so the port group must exist on each host where VMs using it are placed. If the destination host does not have the same standard switch and port group configured, the VM loses connectivity. Option B is incorrect because MAC address restrictions are not a typical cause. Option C is irrelevant because the VLAN ID is part of the port group definition, but the issue here is the port group's absence. Option D is unrelated to standard switch configuration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The standard switch is not configured on the destination host.
Why this is correct
Standard switches are local to each host; the port group must be created on the destination host.
- ✗
The VM's MAC address is not allowed on the destination port group.
Why it's wrong here
No MAC filtering is configured.
- ✗
The VLAN ID on the port group does not match.
Why it's wrong here
The issue is that the port group does not exist, not a VLAN mismatch.
- ✗
The ESXi host's firewall is blocking the VM's traffic.
Why it's wrong here
The firewall does not block VM traffic by default.
