You plug a laptop into a network jack. When you examine the IP address, you see 169.254.23.43. What can you conclude?

A. The network jack is not working.
B. Your laptop has a static IP address configured.
C. The network is configured properly.
D. The DHCP server is down.

D. Any address in the range of 169.254.0.0/16 is a link-local address. It means that the computer has sensed that a network connection is present, but no DHCP is present. The network only allows local communications and no routing. Microsoft refers to this as an APIPA address.
