CompTIA A+ Core 1 (220-1001) — Question 296

Static addressing was replaced with dynamic addressing during network maintenance. Following the maintenance, multiple users began reporting connectivity issues. A technician sees the following when checking the address assignments on a user's workstation:

IP address 169.254.1.2 -
The technician attempts to run commands that will force the PC to request a new IP address, but the technician receives the same address. Which of the following should the technician do NEXT?

Answer options

• A. Run the command ipconfig/flushdns to force the PC to use the DNS server for its next request.
• B. Switch the PC to the wireless network to get the users back to work.
• C. Replace the network cable from the PC to the wall jack.
• D. Check the DHCP server to ensure the scope is large enough for all users.

Correct answer: D

Explanation

The correct answer is D because ensuring that the DHCP server's scope is adequate is crucial for assigning IP addresses to all users. The 169.254.x.x address indicates that the workstation is using APIPA due to a failure to obtain an address from the DHCP server, which suggests that there may not be enough addresses available. Options A, B, and C do not address the underlying issue with DHCP and would not resolve the connectivity problems.
