Which two options can a route pattern be assigned? (Choose two.)

Route patterns are not assigned to a gateway-within-route-group relationship; a gateway inside a route group is reached via a route list, not as a direct assignment target for a route pattern.

A route pattern can be assigned to a route list object in CUCM regardless of whether that route list has any route groups configured; the system allows the assignment even if calls through that list would fail at runtime due to the absence of route groups.

A route pattern can be assigned directly to a gateway device in CUCM, bypassing the route list and route group hierarchy entirely and sending matched calls straight to that gateway.

A layer 3 switch is a network device and is not a valid assignment target for a CUCM route pattern; only gateway devices and route lists are valid targets.

A route list with route groups is functionally correct but is not a distinct assignment category from option B - both B and E describe a route list, and the distinguishing valid pair the exam tests is gateway vs. route list (even an empty one).
