A computer on a local network displays network status errors. A technician executes the `ipconfig` command on the machine and observes an IPv4 address of with a subnet mask of and a blank default gateway. Which of the following statements accurately describe this network status and its cause? (Select TWO.)
- The computer auto-configured its network interface using Automatic Private IP Addressing (APIPA).Answer
- The workstation was unable to contact or reach a active DHCP server on the local network.Answer
- CThe primary DNS server failed to assign a valid dynamic IPv4 address lease to the client adapter.
- DThe workstation successfully established a routable connection to the public internet using a link-local gateway.
Answer
The workstation self-assigned an Automatic Private IP Addressing (APIPA) address because it failed to reach a functional DHCP server.
An IPv4 address beginning with indicates that the operating system engaged Automatic Private IP Addressing (APIPA) after failing to obtain a valid IP lease from a local DHCP server. APIPA enables local link communication among hosts on the same physical segment but cannot route traffic across gateways or to the internet.
