When unable to get an IP address from a server, which of the following represents an APIPA address that a PC might receive?
The correct answer is C. 169.254.1.111. When a PC cannot obtain an IP address from a DHCP server, it self-assigns an Automatic Private IP Addressing (APIPA) address in the 169.254.0.0/16 range.

Why each option
When a PC cannot obtain an IP address from a DHCP server, it self-assigns an Automatic Private IP Addressing (APIPA) address in the 169.254.0.0/16 range.
10.0.1.111 falls in the 10.0.0.0/8 private address range, which is a valid DHCP-assigned or manually configured address - not an APIPA address.
65.71.1.111 is a public routable IP address, not a self-assigned APIPA address.
APIPA is defined by RFC 3927 and assigns addresses exclusively from the 169.254.0.0 to 169.254.255.255 range. When DHCP fails, Windows automatically assigns an address in this range so the host can still communicate locally, but it cannot reach external networks.
192.168.1.111 is in the 192.168.0.0/16 private range, commonly assigned by DHCP or set statically - it is not an APIPA address.
