Answer options

• A. floods unknown destinations to all ports except the receiving port
• B. inspects and drops frames from unknown destinations
• C. forwards frames to a neighbor port using CDP

Correct answer: A

Explanation

The correct answer, A, accurately describes the behavior of frame switching, where frames with unknown destinations are flooded to all ports except the one that received them. Options B, C, and D do not correctly describe characteristics of frame switching; B focuses on dropping frames, C refers to CDP which is not a frame switching function, and D mentions denial of service protection, which is unrelated.
