By default, the next-hop value for these routes is changed by R3 before being sent to R1.

By default, the BGP local-preference value that is assigned on R3 is advertised to R1.

By default, all BGP attributes values must be removed before advertising the routes to R1.

Correct Answer: A, C

By default, BGP does not change the next-hop attribute for iBGP (Internal BGP) routes when advertising them to other iBGP peers. Therefore, the next-hop value is not changed by R3 before being sent to R1. Additionally, BGP local-preference values are used to influence the routing decision within an AS and are shared with iBGP peers. Therefore, the BGP local-preference value assigned on R3 is advertised to R1. BGP attributes, such as local-preference, are not removed when advertising routes within the same AS.
