Explanation

Common mistakes.
- A. The 'exceed high' keyword is not a valid Cisco policer command - 'exceed' must be followed by an action such as 'drop' or 'remark', not a priority level.
- C. The 'exceed drop' command causes out-of-rate packets to be dropped entirely, which does not set a Packet Loss Priority marking on the traffic.
- D. The 'exceed remark' command triggers a remarking action on exceeding traffic but does not configure the Packet Loss Priority to high.
