VCP-DCV Configure and Manage vSphere Networking Practice Question

This VCP-DCV practice question tests your understanding of configure and manage vsphere networking. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

An administrator is configuring a distributed switch for a cluster of ESXi hosts. The requirements are: VLAN 100 for production, VLAN 200 for management, and a separate VLAN 300 for vMotion. The management network should be isolated from production traffic. What is the best practice for configuring these networks on the distributed switch?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.

Question 1mediummultiple choice

Open the full VLAN trunking answer →

A
Create three separate distributed port groups, each with the appropriate VLAN ID, and assign each VM kernel adapter or VM to the correct port group.
This provides isolation and follows best practices.
B
Create one distributed port group with VLAN 100, and use VLAN tagging on the VMs for management and vMotion.
Why wrong: VLAN tagging on VMs is not used for kernel adapters.
C
Use standard switches for management and vMotion to avoid complexity.
Why wrong: Distributed switches offer centralized management and advanced features.
D
Create one distributed port group with VLAN trunk (4095) and use port-based VLAN filtering on the VMs.
Why wrong: VLAN trunk is for guest-level tagging, not for kernel traffic.
E
Create two port groups: one for production (VLAN 100) and one for management+vMotion (VLAN 200) because vMotion can share VLAN with management.
Why wrong: vMotion should be on a separate VLAN for performance and security.

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 three separate distributed port groups, each with the appropriate VLAN ID, and assign each VM kernel adapter or VM to the correct port group.

Option B is correct because best practice is to create separate port groups for each traffic type with specific VLAN IDs. Option A is wrong because VLAN tagging on VMs is not intended for management/vMotion kernel adapters. Option C is wrong because VLAN trunk (4095) is for guest-level tagging. Option D is wrong because vMotion should have its own VLAN. Option E is wrong because distributed switch can handle all.

Key principle: A trunk being up does not mean the VLAN is allowed across it. Always verify the allowed VLAN list and whether the VLAN exists on both switches.

Common exam traps

Common exam trap: an active trunk can still block the VLAN you need

A trunk being up does not prove every VLAN is crossing it. Check allowed VLAN lists, native VLAN mismatch, VLAN existence and access-port assignment.

Detailed technical explanation

How to think about this question

VLAN questions usually combine access-port and trunking clues. The key is to identify whether the issue is local to one switchport, caused by the trunk, or caused by the VLAN not existing where it needs to exist.

KKey Concepts to Remember

Access ports place end devices into a single VLAN.
Trunk ports carry multiple VLANs between switches.
Allowed VLAN lists decide which VLANs can cross a trunk.
Native VLAN mismatch can create confusing symptoms.

TExam Day Tips

Use show vlan brief to verify access VLANs.
Use show interfaces trunk to verify trunk state and allowed VLANs.
Do not treat every same-VLAN issue as a routing problem.

Key takeaway

A trunk being up does not mean the VLAN is allowed across it. Always verify the allowed VLAN list and whether the VLAN exists on both switches.

Real-world example

How this comes up in practice

A help-desk technician troubleshoots why a newly connected PC cannot reach shared printers on the same floor. The cable is good, the switch port is active, but the PC is in VLAN 20 and the printers are in VLAN 10. The uplink trunk only allows VLAN 10. A trunk being up does not mean every VLAN crosses it.

What to study next

Got this wrong? Here's your next step.

Review VLAN allowed lists, native VLAN mismatch detection, and how to verify VLAN membership with show vlan brief and show interfaces trunk. Then practise related VCP-DCV questions on switching, trunking, and access-port configuration.
