What protocol is a vendor-neutral Layer 2 protocol that advertises the identity and capabilities of the host device to other connected network devices?
- LLDP
- NTP
- TFTP
- SNMP
Explanation: Link Layer Discovery Protocol (LLDP) is a vendor-neutral Layer 2 neighbor discovery protocol similar to CDP. It is designed to work with network devices from different manufacturers, allowing them to advertise their identity and capabilities (such as device name, type, and management address) to other physically connected Layer 2 devices. This makes LLDP an essential tool for mapping network topologies in multi-vendor environments.
