An IT specialist sets up a wireless router in a SOHO environment. Afterward, several devices cannot access the internet and are assigned IP addresses starting with 169.254. Which of the following is the best action to resolve this issue?
Answer(s): A
Addresses in the 169.254.x.x range indicate the clients were unable to contact a DHCP server and fell back to APIPA. Since the router provides DHCP in a SOHO setup, restarting it will restore the DHCP service so devices can obtain valid IP addresses again.
