- A
The vSphere Distributed Switch must be configured with enhanced LACP support.
The vDS version must support LACP; enhanced LACP is available in vSphere 6.0+.
- B
Each uplink must be in a separate VLAN to avoid loops.
Why wrong: LACP aggregates links in the same VLAN; separate VLANs are not a prerequisite.
- C
The physical switch ports must be configured as LACP active or passive.
To form a LAG, both ends must agree on the LACP mode; the physical switch must be configured accordingly.
- D
The uplinks must be connected to different physical switches for redundancy.
Why wrong: For standard LACP, all links must terminate on the same physical switch. Cross-switch LACP requires special configurations like vPC.
- E
The physical network switch must support LACP (IEEE 802.3ad).
Without LACP support on the physical switch, LACP negotiation fails.
VCP-DCV Configure and Manage vSphere Networking Practice Question
This VCP-DCV practice question tests your understanding of configure and manage vsphere networking. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Which THREE of the following are prerequisites for configuring LACP on a vSphere Distributed Switch? (Select exactly three.)
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 vSphere Distributed Switch must be configured with enhanced LACP support.
Options A, C, and D are correct. LACP requires compatible physical switches, the vDS must be in enhanced LACP mode, and the physical switch ports must be configured as LACP trunks. Option B is incorrect because the uplinks must be connected to the same physical switch to form a LAG; using different switches requires Multi-chassis LACP. Option E is incorrect because LACP does not require separate VLANs; it aggregates links regardless of VLAN config.
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.
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 vSphere Distributed Switch must be configured with enhanced LACP support.
- ✗
Each uplink must be in a separate VLAN to avoid loops.
- ✓
The physical switch ports must be configured as LACP active or passive.
- ✗

Why it's wrong here
For standard LACP, all links must terminate on the same physical switch. Cross-switch LACP requires special configurations like vPC.
- ✓
The physical network switch must support LACP (IEEE 802.3ad).
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.

FAQ
Questions learners often ask
What does this VCP-DCV question test?
Configure and Manage vSphere Networking — This question tests Configure and Manage vSphere Networking — Access ports place end devices into a single VLAN..
What is the correct answer to this question?
The correct answer is: The vSphere Distributed Switch must be configured with enhanced LACP support. — Options A, C, and D are correct. LACP requires compatible physical switches, the vDS must be in enhanced LACP mode, and the physical switch ports must be configured as LACP trunks. Option B is incorrect because the uplinks must be connected to the same physical switch to form a LAG; using different switches requires Multi-chassis LACP. Option E is incorrect because LACP does not require separate VLANs; it aggregates links regardless of VLAN config.
What should I do if I get this VCP-DCV question wrong?
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.
What is the key concept behind this question?
