CompTIA A+ Core 1 (220-1101) — Question 457

A technician is configuring a static WAN address on a SOHO router. Which of the following should the technician do?

Answer options

• A. Configure UPnP on the WAN.
• B. Enable IPv6 on all LAN interfaces.
• C. Disable DHCP on the required port.
• D. Adjust the LAN subnet mask to 255.255.255.0.

Correct answer: C

Explanation

Disabling DHCP on the required port is essential because a static WAN address means that the router will not be receiving an IP address from a DHCP server, so DHCP needs to be turned off to avoid conflicts. The other options do not directly relate to the configuration of a static WAN address and would not be necessary for this setup.
