An H.323 gatekeeper maintains a separate gateway list, ordered by priority, for each of its zone
prefixes. Suppose that a gateway does not have an assigned priority for a zone prefix. Please
choose the default priority of this gateway.

A.
0

B.
5

C.
10

D.
32

Explanation:
The gatekeeper maintains a separate gateway list, ordered by priority, for each of its zone
prefixes. If a gateway does not have an assigned priority for a zone prefix, itdefaults to priority 5
, which is the median. To explicitly bar the use of a gateway for a zone prefix, the gateway must be
defined as having a priority 0 for that zone prefix. When selecting gateways, the gatekeeper
identifies a target pool of gateways by performing a longest zone prefix match; then it selects from

the target pool according to priorities and resource availability. If all high-priority gateways are
busy, a low-priority gateway might be selected.
