💡 Hint

Common Mistakes

Confusing the Network layer with the Data Link layer.

Thinking switches operate at the Physical layer.

A network switch works at the Data Link layer (Layer 2) to forward frames based on MAC addresses.

Complete the sentence to explain how a switch learns MAC addresses.

Computer Networks

A switch learns MAC addresses by [1] the source address of incoming frames.

💡 Hint

Common Mistakes

Thinking the switch ignores source addresses.

Confusing recording with broadcasting.

Switches record the source MAC address of incoming frames to build their MAC address table.

Fix the error in the sentence about bridging.

Computer Networks

A bridge connects two [1] networks to reduce traffic by filtering frames.

💡 Hint

Common Mistakes

Thinking bridges connect identical networks without segmentation.

Confusing bridges with wireless access points.

A bridge connects two different networks or segments to reduce traffic by filtering frames between them.

4fill in blank

hard

Fill both blanks to complete the description of a switch's MAC address table.

Computer Networks

The MAC address table stores [1] addresses and their associated [2].

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Confusing IP addresses with MAC addresses in the table.

Thinking the table stores protocols instead of ports.

The MAC address table stores MAC addresses and the ports where those addresses were last seen.

5fill in blank

hard

Fill all three blanks to complete the explanation of how a switch forwards frames.

Computer Networks

When a switch receives a frame, it checks the [1] address, looks up the [2] table, and forwards the frame to the correct [3].

💡 Hint

Common Mistakes

Confusing source and destination addresses.

Thinking switches use IP addresses to forward frames.

The switch checks the destination MAC address, looks up the MAC address table, and forwards the frame to the correct port.
