VCP-DCV Configure and Manage vSphere Networking Practice Question
A vSphere administrator needs to provide network connectivity to a set of VMs that must be isolated from all other traffic on the physical network. The VMs are on the same ESXi host and require maximum throughput between them. Which vSphere networking solution should the administrator use?
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
✓
Create a standard switch with an internal-only port group (no uplinks)
A standard switch with no uplinks creates an internal-only network that provides isolation and maximum throughput as traffic stays within the ESXi host memory. Option A requires uplinks and VLAN configuration, allowing potential traffic exposure. Option B requires physical switch support for private VLANs and still uses uplinks. Option C incorrectly uses a VMkernel NIC, which is for management traffic, not VM data.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create a distributed switch with a private VLAN
Why it's wrong here
Requires physical switch support for private VLANs and uses uplinks, not optimal for same-host isolation.
- ✗
Create a standard switch with a VLAN-backed port group
Why it's wrong here
Requires uplinks and VLAN, which does not provide isolation from physical network and may introduce overhead.
- ✗
Create a standard switch with a VMkernel NIC for inter-VM communication
Why it's wrong here
VMkernel NICs are for management, vMotion, etc., not for VM data traffic.
- ✓
Create a standard switch with an internal-only port group (no uplinks)
Why this is correct
Provides full isolation and maximum throughput since traffic never leaves the host.
