CompTIA A+ Core 1 (220-1001) — Question 221

A technician has been informed that multiple users are receiving duplicate IP address warnings on their workstations, and they are unable to browse the Internet.
Which of the following server types should the technician log in to in order to resolve the problem?

Answer options

• A. DNS server
• B. DHCP server.
• C. Proxy server
• D. RADIUS server

Correct answer: B

Explanation

The correct answer is B, the DHCP server, because it is responsible for assigning IP addresses to devices on the network. Duplicate IP address warnings typically indicate a conflict in the DHCP assignments. The other options, such as the DNS server, Proxy server, and RADIUS server, do not manage IP address allocation and would not directly resolve this issue.
