What does a weight represent in the Enhanced Location Call Admission Control mechanism on Cisco Unified Communications Manager? 

Answer options:

A. It defines the bandwidth that is available between locations.
B. It defines the bandwidth that is available on a link.
C. It is the amount of bandwidth allocation for different types of traffic.
D. It is used to provide the relative priority of a link between locations.
E. It is used to provide the relative priority of a location.

D

A weight provides the relative priority of a link in forming the effective path between any pair of locations. The effective path is the path used by Unified CM for the bandwidth calculations, and it has the least cumulative weight of all possible paths. Weights are used on links to provide a "cost" for the "effective path" and are pertinent only when there is more than one path between any two locations.
