medium📝 Analysis Q5 of 15
Step-by-Step Solution
Solution:
Step 1: Understand bridge behavior with unknown MAC
If the destination MAC is unknown, the bridge floods the frame to other segments to find the destination.Step 2: Eliminate other options
Bridges do not drop, send errors, or store frames waiting for destination.Final Answer:
Forwards the frame to all other segments except the source. -> Option AQuick Check:
Unknown MAC frame handling = Forwards the frame to all other segments except the source. [OK]
Quick Trick: Bridge floods unknown destination frames to other segments [OK]
Common Mistakes:
MISTAKES- Thinking bridge drops unknown frames
- Assuming error messages are sent
- Believing frames are stored indefinitely
