CompTIA A+ Core 2 (220-1102) — Question 101

A user who is unable to connect to the network submits a help desk ticket. The assigned help desk technician inquires about whether any recent changes have been made. The user reports there is construction activity in the surrounding offices. The help desk technician proceeds to ping the user's desktop, which does not respond. Which of the following is the MOST likely cause of this issue?

Answer options

• A. A duplicate IP address has been issued to the user's desktop.
• B. The HDD of the OS is failing.
• C. The network cable has become disconnected.
• D. Malware has infected the system.

Correct answer: C

Explanation

The most likely cause of the issue is that the network cable has become disconnected due to the ongoing construction, which would prevent the desktop from responding to pings. A duplicate IP address could cause connectivity issues, but it's less likely given the construction context. A failing HDD would affect the operating system but would not typically prevent network responses. Malware could cause problems, but is less likely than a physical disconnection in this scenario.
