In a network switch, what happens to an entry in the address table when the associated device is inactive for a duration exceeding the aging time?
The switch keeps the entry permanently as a static entry.
The entry's aging timer is automatically extended.
The entry is removed from the address table.
The switch sends a query to the device to verify connectivity.
When an entry in a switch's address table is not refreshed within the configured aging time due to inactivity from the associated device, the switch deletes that entry from the table. This aging mechanism ensures the address table reflects current network topology, conserving memory and enhancing forwarding efficiency by removing stale entries.
