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 exact percent 25

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

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