[All NCP-MCI Questions]

A node with Erasure Coding fails.

What is the impact?

AThe node stops utilizing Erasure Coding.

BPotentially increased amount of data stored in the SSD tier.

CIncreased Controller VM CPU Load.

DAQS unable to do deduplication during the Erasure Coding failure.

Show Suggested Answer

Suggested Answer: A, C

The issue described pertains to the inability to ping the IPMI IPs after moving the IPMI network links to the actual switches with specific VLAN configurations. The two changes that the administrator needs to make are:

A . SSH to AHV and set the VLAN ID using IPMI Tool: Since all VLANs are tagged in the new network configuration, the IPMI network interface needs to be aware of the VLAN it's supposed to communicate on. This can be achieved by setting the VLAN ID using the IPMI Tool on the AHV.

C . SSH to AHV and change the IP address using IPMI tool: If the IPMI IP addresses were initially set in a different subnet that is not routable in the new network configuration, the administrator would need to change the IPMI IP addresses to match the new network configuration. This can be done by SSHing to the AHV and using the IPMI Tool to change the IP address.

Not sure about that, seems like a big issue if true.

Wait, does that mean deduplication is off during the failure?

The node just stops using Erasure Coding, right?

I feel like the AQS deduplication issue could be a factor during an Erasure Coding failure, but I need to double-check that.

Increased Controller VM CPU Load sounds familiar, but I can't remember if that's directly related to the node failure.

I remember something about increased data storage in the SSD tier when there's a failure, but I can't recall the details.

I think if a node fails, it might stop utilizing Erasure Coding, but I'm not entirely sure.

Based on my understanding, the correct answer is that the Erasure Coding failure would increase the Controller VM CPU load. That's option C, I believe.

I'm a bit confused here. Does the node stop utilizing Erasure Coding entirely, or is there some other impact? I'll need to review the options carefully.

Okay, let's see. If a node with Erasure Coding fails, that could potentially increase the amount of data stored in the SSD tier. I think that's option B.

Hmm, maybe the node with Erasure Coding failed because it was too busy coding and erasing all day. Gotta take a break sometimes, you know?

I'm going with A. The node would simply stop utilizing Erasure Coding, which seems like the most straightforward impact.

I think the answer is B. If a node with Erasure Coding fails, the data stored in the SSD tier could potentially increase as the system compensates for the failure.
