Nutanix Exam NCS-Core Topic 2 Question 81 Discussion

Actual exam question for Nutanix's NCS-Core exam

Question #: 81
Topic #: 2

A consultant creates a new cluster using ESXi as the hypervisor. After creating the cluster, the consultant begins to run Life Cycle Manager (LCM) updates. During the LCM upgrade pre-checks, an error is returned.

Which configuration is causing this issue?

AESXi cluster admission control is disabled.

BESXi cluster DRS is enabled.

CESXi cluster HA is enabled.

DESXi cluster admission control is enabled.

Show Suggested Answer

Suggested Answer: D

The error during LCM pre-checks in an ESXi-based Nutanix cluster with HA enabled is most likely due to the ESXi cluster admission control being enabled. Admission control is a feature in VMware ESXi that reserves resources for HA purposes to ensure that sufficient resources are available in the event of host failures. When admission control is enabled, it can interfere with Nutanix LCM operations, which may require resource reallocation or reconfiguration that conflicts with the reserved capacities set by admission control. Disabling admission control during LCM updates would typically resolve this issue. Reference: VMware documentation on HA and Admission Control, Nutanix LCM documentation.

Woah, this is a tricky one. I'd go with B. Enabling DRS can definitely mess with LCM updates. Although, maybe the consultant needs to consult a magic 8-ball to get the right answer.

I think it's C. Enabling HA might be causing the issue.

I think the issue might be with ESXi cluster admission control.

Hmm, I think it's gotta be option D. Enabling admission control can cause issues with LCM updates, right? You know what they say, 'Admission control, the real villain in the cluster'.
