The correct answer is A. The LACP support settings do not exist in the Host Profile.. Hosts provisioned by Auto Deploy are stateless and derive all configuration - including network settings - from a Host Profile. If the Host Profile does not contain LACP settings, deployed hosts will have no LACP configuration and will not send LACP packets.
Question
An administrator is deploying vSphere 5.5. The administrator creates a vSphere Distributed Switch, then uses Auto Deploy to deploy several ESXi hosts. After the hosts are deployed, the administrator notices that LACP packets are not being sent between them. Which condition would cause this issue to occur?
Options
- AThe LACP support settings do not exist in the Host Profile.
- BThe LACP installation bundle is not included in the Image Profile.
- CThe LACP setting is not enabled on vCenter Server.
- DLACP has not been configured on the Auto Deploy server.

Why each option
Hosts provisioned by Auto Deploy are stateless and derive all configuration - including network settings - from a Host Profile. If the Host Profile does not contain LACP settings, deployed hosts will have no LACP configuration and will not send LACP packets.
Auto Deploy provisions stateless ESXi hosts whose entire configuration is applied from a Host Profile at boot time. If LACP support settings are absent from that Host Profile, the deployed hosts receive no LACP configuration for their distributed switch uplinks and therefore never initiate or respond to LACP negotiation, explaining the missing LACP packets.
LACP is a built-in feature of the vSphere Distributed Switch and does not require a separate bundle to be added to an Auto Deploy Image Profile.
LACP is configured at the distributed switch level within vCenter Server and does not have a standalone enable toggle on vCenter Server itself.
The Auto Deploy server handles only PXE booting and image delivery; it has no role in storing or applying LACP or other network configurations.
Concept tested: LACP configuration via Host Profiles with Auto Deploy
