Which function forwards frames to ports that have a matching destination MAC address?
The function that forwards frames to ports that have a matching destination MAC address is frame filtering. Frame filtering refers to the process where a switch determines the correct port to send the frame based on the destination MAC address. In contrast, frame flooding sends frames to all ports, except the one it was received from, when the destination MAC address is unknown. Frame switching is a broader term describing the overall operation of a switch, but it doesn't specifically address the forwarding based on a matching MAC address.
The function that forwards frames to ports that have a matching destination MAC address is D. frame switching. As per the search results, a switch has four functions: learning, flooding, filtering, and switching. Specifically, switching is the function that allows a switch to forward frames to the proper Layer 2 port based on the destination MAC address . This is achieved by using a MAC address table to keep track of which MAC addresses are connected to which switch ports, and then forwarding frames only to the appropriate port based on the destination MAC address .
Answer is D Flooding means that the switch sends the incoming frame to all occupied and active ports (except for the one from which it was received In forwarding , it first looks up the destination address in the MAC Address Table. It then forwards the frame to that specific port.
Please rethink about the answer: In the context of the provided question, the term "frame switching" refers to the general process by which network switches operate. While "frame switching" describes the overall process of how a switch handles and forwards frames, "frame filtering" specifically refers to the step where the switch determines the correct port to send the frame based on the destination MAC address. Given the options, "frame filtering" (Option B) is the most accurate answer for the function that forwards frames to ports with a matching destination MAC address.
D. Frame switching In a switched network, when a frame arrives at a switch, it examines the destination MAC address in the frame header. The switch then uses its MAC address table (also known as a content addressable memory or CAM table) to determine the appropriate port to forward the frame to, based on the matching destination MAC address. This process is referred to as frame switching.
it's B
Frame Filtering: The switch examines the destination MAC address in the frame and checks its MAC address table. If the MAC address is found in the table, the switch identifies the port associated with that MAC address. If the MAC address is not found, the switch may flood the frame to all ports (except the one it came from). Frame Switching: After filtering, the switch forwards (or "switches") the frame to the port corresponding to the destination MAC address. This step ensures the frame reaches its intended recipient. Summary: Filtering determines where the frame should go (decision-making process). Switching performs the actual forwarding of the frame to the correct port. So, in practice: Filtering happens first. Switching follows to forward the frame.
Here's a breakdown: Frame Filtering: Switches use frame filtering to determine the destination port for each incoming frame. They examine the destination MAC address in the frame header and forward the frame only to the port connected to the device with that MAC address. This targeted forwarding prevents unnecessary traffic from being broadcast across the entire network. Frame Switching: While related, "frame switching" is a broader term that encompasses the entire process of how switches handle data frames, including: Receiving frames Processing frames (examining headers) Forwarding frames Therefore, frame filtering is a specific type of frame switching that focuses on determining the correct destination port based on the destination MAC address.
D is correct since its unicasting the known mac address
I see some pick B. The reason I wouldn't pick that is because filtering drops packets, not forward. The function that forward frames is switching. If you want a function that filters/drops frames, go with filtering.
B. frame filtering Explanation: Frame filtering refers to the process in which a switch examines the destination MAC address of an incoming frame and forwards it only to the port where the matching MAC address is located. This is how a switch ensures that frames are only sent to the intended recipient, reducing unnecessary traffic on the network.
The switch always check the MACs, the frame Filtering occurs when they don't match ; if they do the frame is forwarded and it's a frame Switching.
Frame filtering is a part of the overall frame switching process. Filtering involves determining where to send a frame based on its destination MAC address, while switching encompasses the entire process of receiving, filtering, and forwarding frames from one port to another. So response B
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.
D is the correct answer.
