CCNA: Cisco Certified Network Associate — Question 948

What is used to identify spurious DHCP servers?

Answer options

• A. DHCPACK
• B. DHCPREQUEST
• C. DHCPOFFER
• D. DHCPDISCOVER

Correct answer: D

Explanation

The correct answer is D, DHCPDISCOVER, as it is the initial message sent by a client to locate DHCP servers on the network. The other options (DHCPACK, DHCPREQUEST, DHCPOFFER) are part of the DHCP process that occurs after a server is identified and are not used for discovering unauthorized servers.
