What property of ARP allows MAC addresses of frequently used servers to be fixed in the ARP table?

  • A static IP-to-MAC address entry can be entered manually into an ARP table.
  • Entries in an ARP table are time-stamped and are purged after the timeout expires.
  • The type field 0x806 appears in the header of the Ethernet frame.
  • The port-to-MAC address table on a switch has the same entries as the ARP table on the switch.
Explanation & Hint:

The property of ARP (Address Resolution Protocol) that allows MAC addresses of frequently used servers to be fixed in the ARP table is:

“A static IP-to-MAC address entry can be entered manually into an ARP table.”
By manually configuring static entries in the ARP table, you can ensure that the MAC addresses of frequently used servers remain fixed in the table and do not get purged due to the normal dynamic entry timeout. This is a common practice in network management to maintain stability for specific devices.
