Nutanix Exam NCS-Core Topic 2 Question 81 Discussion

Actual exam question for Nutanix's NCS-Core exam
Question #: 81
Topic #: 2
[All NCS-Core Questions]

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?

Show Suggested Answer Hide 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.

It's possible, but admission control being disabled is a common cause of LCM update errors.

But what about DRS and HA being enabled? Could that also be causing the issue?

Option D, all the way! Admission control is the culprit here, no doubt. Though, I can't help but wonder if the consultant is secretly a magician, trying to make the cluster disappear with this LCM update.

B: Yeah, that could definitely be causing the error during the LCM update pre-checks.

Ah, the classic 'ESXi cluster admission control is enabled' problem. Gotta be option D, my friend. Though, I'm still trying to figure out why they call it 'Life Cycle Manager' when it feels more like 'Life Destroyer Manager' half the time.

Yeah, it's frustrating when things don't go smoothly. But at least we know what the issue is now.

Option D is definitely the culprit here. That admission control can be a real pain sometimes.

I agree with Jerlene, if admission control is disabled, it could cause errors during LCM updates.

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.

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'.

Maybe we should disable admission control and see if that resolves the LCM update error.
