300-070 Question #399: Real Exam Question with Answer & Explanation

The correct answer is A: Route group are members within a route list, and a route list is assigned to a route pattern.. In Cisco CUCM, route groups contain gateways, route lists contain route groups in priority order, and route patterns point to route lists to determine call egress paths.

Question

Which statement best describes the relationship between a route pattern, route group, and route list?

Options

ARoute group are members within a route list, and a route list is assigned to a route pattern.
BRoute list contain a range of route patterns, and route groups contain route lists.
CRoute patterns are assigned to either route lists or route groups.
DRoute lists are members within a route list, and a route group is assigned to a route pattern.

Explanation

In Cisco CUCM, route groups contain gateways, route lists contain route groups in priority order, and route patterns point to route lists to determine call egress paths.

Common mistakes.

B. Route lists contain route groups, not route patterns; route patterns are the entry point that reference route lists, not an element contained within them.
C. Route patterns cannot be assigned directly to route groups; they are assigned to route lists or directly to individual gateways, so this option misstates the valid assignment targets.
D. This reverses the correct relationship - route groups are members within route lists, and a route list is assigned to a route pattern, not a route group assigned directly to a route pattern.
