NetApp Certified Data Administrator (NCDA) – ONTAP v3 — Question 27

You observe cyclic redundancy check (CRC) errors on a network port from a node in the cluster.
Which two components would you consider reseating or replacing before you perform actions on the physical port where the errors are reported from the node?
(Choose two.)

Answer options

• A. SFP
• B. cluster interconnect switch
• C. up-stream switch
• D. cable

Correct answer: A, D

Explanation

The SFP (Small Form-factor Pluggable) and the cable are the most likely culprits for CRC errors as they are directly involved in the data transmission and can easily become faulty. The cluster interconnect switch and up-stream switch are less likely to be the immediate cause, as they are further up the network path and generally less prone to such specific errors.
