- D.

Attempted by 1266 students.
Show answer & explanation
Correct answer: D
Answer: The statement "Bridge reduces broadcast domain" is false.
Why this is false: Bridges operate at Layer 2 and will forward broadcast frames to all segments they connect, so they do not reduce the broadcast domain.
Bridges operate at the Data Link layer (Layer 2) and forward frames based on MAC addresses.
Bridges reduce collision domains by segmenting a LAN and sending frames only to the segment containing the destination MAC address.
Bridges forward broadcast frames across connected segments, so the broadcast domain remains the same across those segments.
Routers (Layer 3) are used to separate broadcast domains.
Therefore the false statement is: Bridge reduces broadcast domain.
