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.
