Which two differences should be considered when deciding whether to implement to implement routing policies...

Sequences are added after implementing a route map, but routing policies must be reconfigured when change is needed.

Route maps are implemented using hierarchical policies, but routing policies must be implemented sequentially.

Route maps require an explicit deny at the end of the sequence, but routing policies have an implicit deny at the end of the program.

Route policies require sequence numbers, but route maps are implemented without sequencing.

Route maps are supported in Cisco 10S Software and routing policies are supported in Cisco IOS XR Software.
