CompTIA Network+ (N10-007) — Question 243

A technician attempts to replace a switch with a new one of similar model from the same vendor. When the technician moves the fiber and SFP plug, the switch does not completely boot up. Considering that the config files are the same, which of the following is the MOST likely cause of the failure?

Answer options

• A. Damaged fiber
• B. Corrupted operating system
• C. VLAN mismatch
• D. Bad port

Correct answer: B

Explanation

The most likely cause of the failure is a corrupted operating system (B), as this can prevent the switch from completing its boot process. Damaged fiber (A) and bad port (D) would typically result in connectivity issues rather than a complete failure to boot. VLAN mismatch (C) wouldn't affect the booting process either, as it pertains to network configuration after the device is operational.
