BGP routes and routing see selected answers below for the question below are they correct? if not, please identify the correct selections

Indicate the true statements regarding BGP routes and routing. The AS-PATH attribute contains the list of ASes through which the corresponding route advertisement passed. IBGP uses UDP to disseminate BGP routes to border routers within an AS. Policy is applied first for route selection. A BGP route indicates a prefix along with its attributes. Multi-homed stub ASes are required to handle transit traffic. The AS path from source AS A to destination AS B and that from B to A must go through the same ASes. An autonomous system determines whether to use eBGP or IBGP to advertise routes to neighbor ASes. With BGP, there is exactly one unambiguous path between any source-destination pair. Tier-1 transit ASes know routes to all network prefixes. Shortest AS paths are selected as routes. Policy is used to break ties if there are multiple shortest AS paths. BGP route attributes include AS-PATH and NEXT-HOP. NEXT-HOP attribute is used to differentiate multiple AS-paths to a prefix.
