Step-by-step explanation:

The default maximum amount of time a switch will retain LLDP information before discarding it is 120 seconds (c) .

The Link Layer Discovery Protocol (LLDP) is a vendor-neutral Layer 2 protocol used by devices on a local area network (LAN) to advertise their identity, capabilities, and neighbors. This protocol has a set of timers associated with it, and the maximum age timer determines how long a receiving device should retain the LLDP information before discarding it if no further LLDP updates are received from that sender.
