CompTIA A+ Core 1 (220-1001) — Question 78

A user logs on a PC and receives a message stating there is a duplicate IP address on the network. After a system restart, the user notices the same error.
Which of the following is the MOST probable cause of the error?

Answer options

• A. The user is still logged into another device.
• B. The user has set a static IP address.
• C. The user has moved to a different office.
• D. The user has wireless and wired connections.

Correct answer: B

Explanation

The correct answer is B because a static IP address can lead to a conflict if another device on the network is using the same address. The other options are less likely causes; for instance, being logged into another device (A) does not usually cause an IP conflict, moving offices (C) would not affect IP assignment, and having both connection types (D) does not inherently create a duplicate IP issue.
