An administrator is unable to remove an ESXi 6.x host from a vSphere Distributed Switch. What are two likely reasons for this issue? (Choose two.)
The correct answer is A. Vmkernel interfaces on the switch are still in use. D. VM Network adapters are connected to this switch. A host cannot be removed from a vSphere Distributed Switch if VMkernel interfaces or VM network adapters are still actively connected to that switch.

Why each option
A host cannot be removed from a vSphere Distributed Switch if VMkernel interfaces or VM network adapters are still actively connected to that switch.
VMkernel interfaces (management, vMotion, iSCSI, etc.) bound to VDS port groups create active dependencies that block removal; they must be migrated to a vSphere Standard Switch or deleted before the host can leave the VDS.
Adapters connected to a different switch have no association with this VDS and cannot block its removal.
Physical NICs that have already been migrated away from this VDS are no longer bound to it and therefore do not prevent host removal.
Virtual machine network adapters still connected to VDS port groups create active port bindings on that switch; each VM NIC must be migrated or disconnected before the host can be removed from the distributed switch.
