Which two statements about the bgp deterministic-med and bgp always-compare-med commands are true？（）

A、The bgp deterministic-med command is used to influence the BGP route selection process to cause the MED attribute to have higher precedence over the AS path length

B、The bgp always-compare command is used to influence the BGP route selection process to cause the MED attribute to have higher precedence over the AS path system

C、Enabling the bgp deterministic-med command ensures the comparison of the MED variable when choosing routes advertised by different peers in the same autonomous system.

D、Enabling the bgp always-compare-med command ensures the comparison of the MED variable for paths from neighbors in different autonomous systems.

E、The bgp deterministic-med and bgp always-compare-med commands are enabled by defult.
