220-1102 Question #151: Real Exam Question with Answer & Explanation

Question

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?

Options

• AA duplicate IP address has been issued to the user's desktop.
• BThe HDD of the OS is failing.
• CThe network cable has become disconnected.
• DMalware has infected the system.

Explanation

Construction activity and an unresponsive ping when a user is unable to connect to the network strongly suggest a physical network layer issue.

Common mistakes.

• A. A duplicate IP address would cause network issues, but the ping might still partially work, or the system might show an IP conflict warning, and it's less directly linked to construction activity.
• B. A failing HDD for the OS would likely prevent the system from booting or cause general system instability, but it wouldn't specifically manifest as an unresponsive ping if the system is otherwise running.
• D. While malware can cause network issues, it is less likely to result in a completely unresponsive ping in conjunction with recent construction activity as a primary cause.

Concept tested. Network troubleshooting, physical layer issues, network outages
