Network Technology Associate · IP Addressing
A user reports being unable to access any websites. A technician runs
ipconfigon the user's machine and sees the IP address is 169.254.10.25. What is the most likely cause of the problem?Show answer & explanation
Correct answer: B
An IP address in the 169.254.x.x range is an Automatic Private IP Addressing (APIPA) address. Windows assigns an APIPA address to a device when it is configured for DHCP but is unable to contact a DHCP server to obtain a valid IP address. This allows for communication on the local subnet but not for routing to the internet.
