CompTIA Network+ (N10-007) — Question 531

A switch is being configured for installation into a new building. The network design is such that the only DHCP server resides in the datacenter. A traditional three-layer network hierarchy is being used, and all buildings have a Layer 3 connection back to the core. Which of the following should the technician configure to get DHCP working properly in the new building?

Answer options

• A. The SMTP relays in the datacenter
• B. The MAC address reservations
• C. The IP helper address on the switch
• D. The ARP forwarding on the switch

Correct answer: C

Explanation

The correct answer is C, as configuring the IP helper address on the switch allows DHCP requests from clients in the new building to be forwarded to the DHCP server in the datacenter. Options A and B are unrelated to DHCP functionality, and option D, ARP forwarding, does not pertain to DHCP configuration either.
