Discuss Nutanix NCP-MCI Exam Topic 2 Question 26

A two-node ROBO cluster is configured with a witness VM.

What happens when Node A goes down?

AThe- cluster becomes unavailable and goes into read-only mode.

BAll operations and services on the Node B are shut down and go into a waiting state.

CThe cluster is unaffected and no administrator intervention is required.

DNode B sends a leadership request to the Witness VM and goes into single-node mode.

Suggested Answer: A, C

According to the CPU (%) - VMware Docs web search result2, one of the possible causes of high CPU ready % is over-provisioning vCPUs for a VM or having too many VMs on a host. CPU ready % indicates the percentage of time that the VM was ready, but could not get scheduled to run on the physical CPU. High CPU ready % can lead to VM performance problems, such as slow response time or application latency. To improve VM performance, the administrator should reduce the number of vCPUs assigned to VMs or reduce the number of VMs on the hosts, so that there is less contention for CPU resources.

If Node A goes down, Node B should handle it smoothly.

Mose 11 months ago

Wait, are you sure about that? Sounds too easy.

Phung 11 months ago

Definitely D, that's how it works!

Jacob 11 months ago

I think the cluster stays up, right?

Katy 11 months ago

Node B takes over with the witness VM!

Katheryn 11 months ago

I'm leaning towards option D because it sounds familiar from our study sessions, but I could be mixing it up with another scenario.

Hannah 12 months ago

I feel like I read that Node B would send a request to the Witness VM, but I can't recall if that means it goes into single-node mode or something else.

Fallon 12 months ago

I remember a practice question where the cluster remained operational with just one node, so I think option C could be correct.

Jaime 1 year ago

I think when Node A goes down, Node B might take over, but I'm not sure if it needs to contact the Witness VM or not.

Carma 1 year ago

I think the key here is understanding how the ROBO cluster handles single-node scenarios. I'll need to carefully consider the implications of the witness VM in this setup.

Ernest 1 year ago

Based on the options, it seems like the cluster should be able to maintain operations even with Node A going down. The witness VM should help Node B take over leadership.

Tijuana 1 year ago

I'm a bit confused here. Does the cluster go into read-only mode, or does Node B take over? I'll need to review the ROBO cluster failover behavior.

Ezekiel 1 year ago

Okay, let's see. With a two-node ROBO cluster and a witness VM, I'm guessing the cluster will try to maintain availability if one node goes down.

Miss 1 year ago

Hmm, this looks like a tricky one. I'll need to think carefully about the cluster configuration and how it responds to node failures.

Nan 1 year ago

Whoa, hold up! Option B sounds like a total shutdown. That can't be right. I'm feeling confident about Option C - let the cluster keep on trucking without any intervention.

User 3: Yeah, I also think Option C is the best choice for this scenario.

User 2: I think Option C makes more sense, let the cluster keep running smoothly.

User 1: I agree with you, Option B does sound extreme.

Misty 1 year ago

Hmm, I'm leaning towards Option A. Losing a node in a two-node cluster sounds like it would bring the whole thing down. Better play it safe, right?

User1: Definitely, it's always better to plan for potential failures in a cluster setup.

User1: I think you're right, Option A seems like the safest choice.

Rolande 1 year ago

Ha! Witness VMs, I've always thought they were more trouble than they're worth. Anyway, I'm going with Option D. Gotta love that single-node mode!

Stephaine 1 year ago

↳ replying to Rolande

Definitely, having Node B switch to single-node mode automatically is a great feature.

Emilio 1 year ago

↳ replying to Rolande

I think Option D is the way to go as well. It's good to have that failover in place.

Davida 1 year ago

↳ replying to Rolande

Yeah, single-node mode is definitely convenient. No need to worry about the cluster going down.

Gwenn 1 year ago

↳ replying to Rolande

I agree, Witness VMs can be a hassle. Option D does seem like the best choice.

Carlota 1 year ago

Option C seems plausible, but I'm not entirely convinced. I'd need to double-check the specifics of ROBO cluster failover behavior to be sure.

Amie 1 year ago

User 2: I agree, Node B would send a leadership request to the Witness VM.

Jody 1 year ago

↳ replying to Carlota

User 1: I think option D is the correct answer.

Rosann 2 years ago

But if Node A goes down, Node B should take over, right?

Frankie 2 years ago

I disagree, I believe it's A.

Rosann 2 years ago

I think the answer is D.
