- A
Use the vSphere Web Client to add the host as an exception before the outage.
Why wrong: The web client is unavailable during the outage, and it does not configure DCUI access.
- B
Configure the DCUI access list with specific users or groups before enabling Lockdown Mode.
This allows designated users to access DCUI even when Lockdown Mode is active.
- C
Enable Strict Lockdown Mode to allow vCenter access exclusively.
Why wrong: Strict Lockdown Mode prevents all local access including DCUI.
- D
Disable Lockdown Mode only during the maintenance window.
Why wrong: Cannot disable Lockdown Mode without vCenter or DCUI access.
Question 94 of 521
Configuring DCUI Access List for Lockdown Mode
This VCP-DCV practice question tests your understanding of vsphere security. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. A key principle to apply: lockdown Mode (Normal). 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.
A vSphere administrator is implementing Lockdown Mode on an ESXi host that hosts critical VMs for a healthcare application. After enabling Normal Lockdown Mode, the administrator tests that vCenter can still manage the host, but the local DCUI root account is disabled. Later, a network outage occurs, causing vCenter to become unreachable. The administrator needs to access the host directly via DCUI to perform emergency troubleshooting. The host's DCUI is still running, but the local root account is disabled due to Lockdown Mode. What should the administrator have configured to ensure DCUI access during such an outage?
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
✓
Configure the DCUI access list with specific users or groups before enabling Lockdown Mode.
Option B is correct. Normal Lockdown Mode disables the local root account for DCUI access, but it allows you to pre-configure a DCUI access list with specific users or groups (local or AD) who can still log in via DCUI. By adding a user to this list before enabling Lockdown Mode, the administrator could have gained DCUI access during the outage. Option A is incorrect because the vSphere Web Client does not have an option to add host exceptions for DCUI; the DCUI access list must be configured directly on the host or via host profile. Option C is incorrect because Strict Lockdown Mode disables all local accounts, including the DCUI access list, making DCUI entirely unavailable. Option D is incorrect because disabling Lockdown Mode requires vCenter Server access, which is unavailable during the outage.
Key principle: Lockdown Mode (Normal)

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap is confusing Normal Lockdown Mode with Strict Lockdown Mode. Normal Lockdown Mode only disables the root account and allows a preconfigured DCUI access list. Strict Lockdown Mode disables all local accounts, including the DCUI access list, preventing any direct DCUI login.

Real-world example
How this comes up in practice
A practitioner preparing for the VCP-DCV exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Lockdown Mode (Normal) Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
