VCP-DCV Configure and Manage vSphere Networking Practice Question
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 E are correct. For LACP on a vSphere Distributed Switch, the vDS must be configured with enhanced LACP support (option A). The physical switch ports must be configured for LACP, either in active or passive mode (option C). Additionally, the physical network switch must support LACP (IEEE 802.3ad) (option E). Option B is incorrect because each uplink does not need to be in a separate VLAN; LACP works across VLANs and VLAN configuration is independent. Option D is incorrect because the uplinks must be connected to the same physical switch to form a LAG; using different switches requires Multi-chassis LACP (e.g., MLAG).
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.
Why this is correct
The vDS version must support LACP; enhanced LACP is available in vSphere 6.0+.
- ✗
Each uplink must be in a separate VLAN to avoid loops.
Why it's wrong here
LACP aggregates links in the same VLAN; separate VLANs are not a prerequisite.
- ✓
The physical switch ports must be configured as LACP active or passive.
Why this is correct
To form a LAG, both ends must agree on the LACP mode; the physical switch must be configured accordingly.
- ✗
The uplinks must be connected to different physical switches for redundancy.
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).
Why this is correct
Without LACP support on the physical switch, LACP negotiation fails.
