Which entity contains one or more route groups?

• A. Line Group
• B. Route Pattern
• C. Translation Pattern
• D. Route List

Answer: (D)

Route List is the container used for outbound dial routing in CUCM. It holds one or more Route Groups, and each Route Group contains one or more Routes that point to gateways or trunks. This structure lets you define multiple potential paths for a call and control failover or fallback options. Line Groups, Route Patterns, and Translation Patterns serve other parts of the dialing logic: Line Groups organize lines for selection, Route Patterns map digit strings to Route Lists, and Translation Patterns modify digits before routing. So the entity that contains one or more route groups is Route List, because it is the top-level object that aggregates Route Groups to form the complete outbound routing path.
