A network technician is troubleshooting a client computer on a office network. Upon executing the ipconfig command, the technician sees that the network interface has an IPv4 address of 169.254.42.88 with a subnet mask of 255.255.0.0. Which of the following best explains why the client received this IP address?
- The computer was unable to contact a DHCP server and automatically assigned itself an APIPA address.Answer
- BThe primary DNS server assigned an APIPA address because it failed to resolve the host local computer name.
- CAn unmanaged switch blocked network traffic because IP address assignment requires a Layer 3 router.
- DThe network card failed to establish an encrypted connection using HTTPS port 443 instead of HTTP port 80.
Answer
The computer was unable to contact a DHCP server and automatically assigned itself an APIPA address.
An IP address within the 169.254.0.0/16 scope indicates that the computer's operating system assigned an APIPA address because it could not communicate with a DHCP server to obtain an IP lease.
