Zorluk: KolayIP Addressing and Network Configuration

A network technician runs the command 'ipconfig /all' on a newly deployed workstation and receives an IPv4 address of 169.254.112.45 with a subnet mask of 255.255.0.0. Which of the following statements correctly describe the network status and capabilities of this workstation? (Select TWO.)

  1. The workstation automatically assigned itself an APIPA address because it could not reach a functional DHCP server.Cevap
  2. The workstation can still communicate with other systems on the same local subnet that are using APIPA addresses.Cevap
  3. C
    The workstation can successfully navigate the internet and access remote cloud resources using its assigned default gateway.
  4. D
    The local DNS server dynamically leased this IP address to the workstation upon network initialization.

Cevap

The workstation automatically generated an APIPA address after failing to receive a lease from a DHCP server, which allows for local subnet communications with other APIPA-configured hosts but does not provide default gateway access to external networks or the internet.
Addresses in the 169.254.0.0/16 range are automatically assigned by the operating system via APIPA when a DHCP server cannot be reached. APIPA enables link-local communication, allowing hosts on the same physical broadcast domain with APIPA addresses to communicate with each other.

Adım Adım Çözüm

1
Analyze the IP address output 169.254.112.45
Identify the IP address as belonging to the 169.254.0.0/16 address block reserved for Automatic Private IP Addressing (APIPA).
APIPA is activated by client operating systems when DHCP server discovery fails or times out.
2
Evaluate communication scope for APIPA addresses
Determine that local link-local traffic works between APIPA clients on the same switch/segment, but non-routable nature prevents external/internet communication.
APIPA configurations do not include a default gateway address.
