1.	Which RLC mode adds the least amount of delay to user traffic?(a) Unacknowledged mode (UM)(b) Acknowledged mode (AM)(c) Low latency mode (LM)(d) Transparent mode (TM)I got this question in a national level competition.This intriguing question comes from Long Term Evolution (LTE) in division 4G of Wireless/Mobile
Answer» The correct choice is (d) TRANSPARENT mode (TM) To EXPLAIN: The transparent mode ENTITY in RLC does not add any overhead to the upper LAYER SDUs. The entity just TRANSMITS the SDUs coming from upper layer to MAC.
