A technician installed a new router at a small office. After the installation, the technician notices that all devices have a 169.254.X.X IP address. Printers and fileshares are still working, but PCs cannot access the internet. Which of the following should the technician configure on the router to enable devices to connect to the internet?

APIPA, or Automatic Private IP Addressing, is a feature that allows devices to assign themselves an IP address in the absence of a DHCP server. While it enables local communication within the same subnet, it does not provide internet connectivity since APIPA addresses are not routable beyond the local network. Therefore, configuring APIPA will not resolve the issue of accessing the internet.

DNS, or Domain Name System, is responsible for translating human-readable domain names into IP addresses. While vital for accessing websites, DNS alone cannot resolve the issue of devices being unable to connect to the internet if they lack valid, routable IP addresses. Without proper IP assignment, DNS settings will not function, rendering the internet inaccessible.

SMB, or Server Message Block, is a network protocol used for sharing files and printers within a local network. While useful for local resource sharing, it does not address the fundamental issue of IP address assignment or internet connectivity. Thus, configuring SMB will not assist in resolving the internet access problem.
