Zorluk: KolayWired and Wireless Network Issues

A technician is troubleshooting a workstation that lost access to network share folders and the internet. Running `ipconfig` on the workstation yields an IP address of 169.254.89.12169.254.89.12 and a subnet mask of 255.255.0.0255.255.0.0. Which of the following statements correctly describe this network state? (Select TWO.)

  1. The workstation has automatically assigned itself an Automatic Private IP Addressing (APIPA) address.Cevap
  2. The workstation failed to contact or receive an IP address lease from a DHCP server.Cevap
  3. C
    The local DNS server failed to resolve the workstation's domain name to an IP address.
  4. D
    The network interface card link light is off because Layer 1 physical connectivity is broken.

Cevap

The workstation has self-assigned an APIPA address because it was unable to obtain an IP address lease from a DHCP server.
An IP address starting with 169.254.x.x indicates Automatic Private IP Addressing (APIPA). This occurs automatically when a network host is configured for dynamic IP addressing but cannot reach or receive a response from a DHCP server.

Adım Adım Çözüm

1
Analyze the output of the ipconfig command.
The IP address obtained is 169.254.89.12.
Addresses within 169.254.0.0/16 belong to the APIPA block.
2
Identify the underlying cause of an APIPA address assignment.
Confirm DHCP failure.
APIPA is activated only when a system requests an IP via DHCP and receives no response within the timeout period.
