• Chose B1

  The correct answer is: B. frame filtering 🧠 Explanation: Frame filtering is the process by which a switch examines the destination MAC address of an incoming frame and forwards it only to the port where that MAC address is known to reside. This is a key function of Layer 2 switching, helping to optimize traffic flow and reduce unnecessary transmissions.

• Chose D1

  The correct answer is D. frame switching because it refers to a switch forwarding frames only to the port that matches the destination MAC address, using its MAC address table to direct traffic efficiently. In contrast, frame flooding (A) sends frames out all ports when the destination MAC is unknown, frame filtering (B) involves blocking or dropping frames rather than forwarding, and frame pushing (C) is not a standard term related to Ethernet frame forwarding. Thus, frame switching is the precise function that selectively forwards frames based on MAC address.

• Chose B1

  Frame filtering is the process used by network switches to forward Ethernet frames only to the port that matches the destination MAC address. This improves efficiency by ensuring that frames are sent only where needed, rather than broadcasting them to all ports. ❌ D. Frame Switching – While "switching" is a general term for moving frames between ports, the correct term for forwarding frames based on MAC addresses is frame filtering.
