A technician is configuring a static WAN address on a SOHO router. Which of the following should the technician do?
The correct answer is C. Disable DHCP on the required port.. To configure a static WAN address on a SOHO router, the technician must disable DHCP on the WAN port because DHCP automatically assigns dynamic IP addresses, which conflicts with a static configuration.

Why each option
To configure a static WAN address on a SOHO router, the technician must disable DHCP on the WAN port because DHCP automatically assigns dynamic IP addresses, which conflicts with a static configuration.
UPnP (Universal Plug and Play) is a protocol that allows devices to discover and communicate with each other on a network, and it is unrelated to configuring a static WAN IP address.
Enabling IPv6 on LAN interfaces is a separate configuration concern for internal network addressing and does not directly relate to setting a static IPv4 WAN address.
When configuring a static WAN address, the router should not attempt to obtain an IP address dynamically from an upstream DHCP server. Disabling DHCP on the WAN interface ensures that the manually entered static IP address, subnet mask, gateway, and DNS server settings are used instead of dynamic assignments.
Adjusting the LAN subnet mask to 255.255.255.0 changes the internal network's addressing scheme, which is distinct from configuring the external static WAN IP address.
