The correct answer is D. All network switch ports have spanning tree protocol disabled. See the full explanation below for the reasoning.
Question
An administrator of a Provisioning services environment notices that several of the target devices that are configured to use a vDisk on the provisioning server are randomly failing to start and shut down. What should the administrator check to prevent this issue from occurring?
Options
- AThe SOAP Service is running.
- BHigh availability is enabled on the vDisks.
- CThe target devices are configured to start up from hard disk.
- DAll network switch ports have spanning tree protocol disabled.

Samuel O.Apr 13, 2026D is your answer. Random boot and shutdown failures in PVS environments almost always trace back to spanning tree delays on the switch ports, where the port spends too long in the listening and learning states before forwarding, causing the PXE boot process to time out before the target device ever gets a response from the provisioning server.
Imani T.Apr 14, 2026Agreed, and worth adding that the fix is literally one command on most managed switches, enabling PortFast or the vendor equivalent on those access ports so they skip straight to forwarding instead of burning 30-plus seconds in listening and learning.
Imani T.Apr 17, 2026High availability on the vDisks is exactly what prevents random boot failures, go with B.
Samuel O.Apr 18, 2026Imani, HA on the vDisks covers redundancy if a Provisioning Server goes offline, but it does not address the target device side of a random boot failure, which is what D targets by increasing the number of login retries so the device keeps attempting to connect instead of failing out. The question is asking what stops the intermittent drop, not what keeps the image accessible.
Prof. SaraApr 23, 2026B is a trap, random PXE failures point straight to D.
