CompTIA Network+ (N10-008) — Question 160

A security administrator is trying to prevent incorrect IP addresses from being assigned to clients on the network. Which of the following would MOST likely prevent this and allow the network to continue to operate?

Answer options

• A. Configuring DHCP snooping on the switch
• B. Preventing broadcast messages leaving the client network
• C. Blocking ports 67/68 on the client network
• D. Enabling port security on access ports

Correct answer: A

Explanation

Configuring DHCP snooping on the switch is effective because it allows the switch to monitor DHCP messages and prevent rogue DHCP servers from assigning incorrect IP addresses. The other options do not directly address the issue of controlling DHCP assignments and could hinder normal network operations.
