Question
What is a limitation of TP line repeaters compared with segment couplers?
Answer
B — They are unaware which device address is in which subsegment and have no filter table, so they forward all traffic.
Correct: repeaters cannot tell where an address lives and have no filter table, so every telegram reaches every segment.
