CompTIA Network+ (N10-006) — Question 38

After moving to an adjacent cubicle, a user is reporting that the VoIP phone is randomly rebooting. When the technician relocates the equipment back to the previous space, the phone functions properly. No other stations are being affected.
Which of the following is the MOST likely cause?

Answer options

• A. Attenuation
• B. Bad UPS
• C. Cable short
• D. Misconfigured DNS

Correct answer: C

Explanation

The most likely cause of the VoIP phone rebooting is a cable short, which can occur due to physical damage or interference when relocating the device. Attenuation, a bad UPS, and misconfigured DNS would not typically cause a device to reboot in this manner, especially when the phone functions correctly in its original location.
