In your production database, you have multiple resource plan directives that refer to the customer group DB_GRP. Which two statements are correct? ()
A

The parallel degree limit for DB_GRP will be the minimum of all the incoming values.

B

The parallel degree limit for DB_GRP will be the maximum of all the incoming values.

C

The maximum estimated execution time for DB_GRP would be the most nonrestrictive of all incoming values.

D

If a session switched from the DB_GRP consumer group to another consumer group because it exceeded the prescribed switch time, then that session would not execute if the active session pool for the new consumer group was full.

E

Is a session switched from the DB_GRP consumer group to another consumer group because it exceeded the prescribed switch time, then that session would execute even if the active session pool for the new consumer group was full.
