Link Layer Discovery Protocol (LLDP)is a Layer 2 discovery protocol that allows network devices to advertise identity and capabilities to directly connected neighbors. While LLDP is useful for basic topology discovery, it has two key limitations inWired Assurance client identification:
"LLDP operates at Layer 2 between directly connected devices and must be explicitly enabled on all participating network elements to provide neighbor information. It cannot discover devices beyond the first physical hop." Option A:Correct- LLDP must beconfigured and enabledon each network device to function.
Option B:Incorrect - LLDP itself is scalable but limited to direct adjacency.
Option C:Correct- LLDP only worksbetween directly connected devices.
Option D:Incorrect - not all clients support LLDP; however, the question asks forlimitations of using LLDP, not lack of support.
