Which capability is support by LLDP-MED but not by Cisco Discovery Protocol?

A. B. C. D. E.A.
LLDP-MED supports both LAN speed and duplex discovery.
Cisco Discovery Protocol supports duplex discovery only, but this limited support is not seen as a problem because if there is a speed mismatch, LLDP-MED and Cisco Discovery Protocol cannot be exchanged and thus cannot be used to detect the mismatch.
LLDP-MED (Link Layer Discovery Protocol-Media Endpoint Discovery) and Cisco Discovery Protocol (CDP) are both protocols used for network discovery and management. However, LLDP-MED has some capabilities that are not supported by CDP.
Out of the options provided, the capability supported by LLDP-MED but not by CDP is network policy discovery, which is option B.
LLDP-MED is an extension of LLDP that allows for the exchange of additional information between network devices. LLDP-MED can discover and exchange information about network policies, such as VLAN assignment, Quality of Service (QoS) policies, and power management policies, which can be used to provide better network optimization and security.
On the other hand, CDP is a Cisco proprietary protocol that is used to discover and manage Cisco network devices. CDP can discover information such as the device type, IP address, and port ID, but it does not support network policy discovery.
To summarize, LLDP-MED supports network policy discovery, which is not supported by CDP. This capability allows network devices to exchange information about network policies, which can be used to optimize network performance and security.
