CompTIA Network+ (N10-008) — Question 485

A technician is investigating a SAN switch that has a high number of CRC errors. Which of the following is the MOST likely cause of the errors?

Answer options

• A. Break in the fiber
• B. Bad switch port
• C. Mismatched duplex
• D. Memory errors

Correct answer: A

Explanation

The correct answer is A, as a break in the fiber can lead to signal loss and result in CRC errors. While a bad switch port (B), mismatched duplex settings (C), and memory errors (D) can also cause issues, they are less likely to be the primary cause of high CRC errors compared to a fiber break.
