Cisco 300-540 Exam - Topic 1 Question 7 Discussion

Actual exam question for Cisco's 300-540 exam

Question #: 7
Topic #: 1

Refer to the exhibit.

Refer to the exhibit. An engineer is troubleshooting a physical configuration issue in Cisco NFVI. Which two observations should be made? (Choose two.)

A. The node allows two disks to fail. B. One RAID 1 disk failed. C. The node is still functional. D. The node is no longer functional. E. Two RAID 1 disks failed.

BOne RAID 1 disk failed -- correct.

CThe node is still functional -- correct; RAID1 can tolerate a single disk failure.
The other options are incorrect:
A and E suggest two disk failures, which is not indicated.
D would be true only if both disks failed; with one disk still online, the node continues to function, though in a degraded state.

Show Suggested Answer

Suggested Answer: B, C

From the RAID controller output:

The RAID1 virtual drive is shown as ''Dgrd'' (degraded) with a note: ''RAID 1 in degraded state.''

In the PD LIST, one disk (slot 2) is marked ''UGood -- active disk in slot 2 disconnected from drive group 0'', while the other (slot 3) is ''Onln 0'' (online and part of drive group 0).

This means:

In a RAID 1 mirror, only one disk may fail while the array remains available.

Here, one disk has failed/disconnected, the other is still online the array is degraded but operational.

Therefore:

I practiced a similar question where we had to identify node functionality after disk failures. I think B and C are definitely the right choices here.

I'm a bit unsure about option A; I thought RAID 1 only allows one disk to fail, but I guess it’s not clear from the question.

I remember studying RAID configurations, and I think RAID 1 can handle one disk failure, so C makes sense.
