C. 10
D. 32
Correct Answer: B
Explanation/Reference:
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, it defaults 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.
