Which of the following descriptions about the reset ip ip-prefix command is correct?

Question

Options

• AThis command enables the router interface to recall the prefix list during traffic filtering (Traffic-Filter)
• BThis command can clear the statistical data of IPv4 address prefix list
• CThis command can pre-match routing entries
• DThis command enables the router to recall the prefix list during routing protocol injection

• A
  11% (2)
• B
  79% (15)
• C
  5% (1)
• D
  5% (1)

Explanation

Option B is correct because the reset ip ip-prefix command is an operational/maintenance command on Huawei VRP devices that clears the match-count statistics accumulated by IPv4 prefix list rules - it resets the hit counters back to zero without affecting the prefix list configuration itself.

Option A is wrong because "recalling" a prefix list for Traffic-Filter (interface-level traffic filtering) is handled by configuration commands that apply the prefix list to an interface, not by a reset operation. Option C is wrong because pre-matching or testing routing entries against a prefix list is a separate verification concept; the reset command does not evaluate or match any routes. Option D is wrong because applying a prefix list during route injection or redistribution is controlled by routing protocol configuration commands, and again, a reset operation does not trigger or re-apply any policy.

Memory tip: In Huawei VRP, "reset" commands always clear runtime state or counters - they never activate, apply, or recall policies. If you see "reset" in a command name, the answer will always be about clearing statistical or operational data, not about enabling a feature.
