On your EX Series switch you must configure a delay buffer for the best effort queue scheduler
named BE-sch which restricts the buffer usage to only 25 percent of the available buffer size.
Which configuration statement will accomplish this task?

A.
[edit class-of-service schedulers BE-sch]
user@switch# set buffer-size buffer-size temporal 25

B.
[edit class-of-service schedulers BE-sch]
user@switch# set buffer-size buffer-size temporal 25 exact

C.
[edit class-of-service schedulers BE-sch]
user@switch# set buffer-size percent 25

D.
[edit class-of-service schedulers BE-sch]
user@switch# set buffer-size exact percent 25
