D-XTR-MN-A-24 practice question 1 of 15

What is the impact of a serial cable failure in a multi X-Brick XtremIO X1 cluster?

Full set: 55 questions

Answer options

A: Failure of more than half of the COM cables forces the cluster into a degraded mode Correct answer

B: Failure of one serial cable makes the BBU not visible to the cluster's environment monitoring

C: Failure of one COM cable results in a loss of service

D: Failure of more than half of the BBU COM cables results in a loss of service

Correct Answer:

A. Failure of more than half of the COM cables forces the cluster into a degraded mode

Explanation

In a multi X-Brick XtremIO X1 cluster, the failure of more than half of the COM (communication) cables forces the cluster into a degraded mode. This degraded mode is a protective measure to ensure that the cluster can continue operating with reduced performance and redundancy until the issues with the COM cables are resolved.
