Question

A network technician is deploying a new machine in a small branch office that does not have a DHCP server. The new machine automatically receives the IP address of 169.254.0.2 and is unable to communicate with the rest of the network. Which of the following would restore communication?

Options

  • AStatic entry
  • BARP table
  • CAPIPA address
  • DNTP specification

Why each option

A new machine automatically receiving a 169.254.x.x IP address indicates an APIPA address due to the absence of a DHCP server, and to restore network communication, a static IP address must be manually configured.

AStatic entryCorrect

Since there is no DHCP server, the machine received an APIPA address (169.254.x.x), which prevents communication outside its local subnet. Configuring a static IP address, subnet mask, gateway, and DNS server manually will allow the machine to communicate with the rest of the network.

BARP table

An ARP table maps IP addresses to MAC addresses and is a consequence of network communication, not a method to restore it when IP addressing is incorrect.

CAPIPA address

APIPA address (Automatic Private IP Addressing) is the *result* of the problem, not a solution; it's the automatically assigned address when a DHCP server isn't found.

DNTP specification

NTP (Network Time Protocol) specification deals with time synchronization and has no direct bearing on resolving IP address assignment issues or restoring basic network communication.
