Cisco 400-051 Exam

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

  • A. LAN speed discovery
  • B. network policy discovery
  • C. location identification discovery
  • D. power discovery
  • E. trust extension
Answer: Option A.
Explanation: 

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.
