CompTIA Network+ (N10-007) — Question 674

Client PCs are unable to receive addressing information from a newly configured interface on a router. Which of the following should be added to allow the clients to connect?

Answer options

• A. DHCP lease time
• B. IP helper
• C. TTL
• D. DNS record type

Correct answer: B

Explanation

The correct answer is B, IP helper, which is used to forward DHCP requests from clients to a DHCP server in a different subnet. The other options, such as DHCP lease time (A), TTL (C), and DNS record type (D), do not facilitate communication between client PCs and a DHCP server.
