質問 1：
Which action does the packet remarking process perform?
A. It determines the packet's forwarding class based on classification criteria
B. It modifies the current packet's forwarding class to indicate promotion or demotion
C. It modifies the current TOS, DSCP, EXP, or Dot1p marking to indicate promotion or demotion
D. It sets the TOS, DSCP, EXP, or Dot1p field based on classification criteria
正解：D

A. All out-of-profile traffic will be dropped before any in-profile is dropped.
B. When an in-profile packet arrives and the shared buffer utilization is at 69%, the packet will have approximately a 60% likelihood of being discarded.
C. The time average factor of 0 will discard all packets arriving in the shared buffer pool.
D. The highest probability with which an out-of-profile packet can be dropped is 20%.
