General exam question G8C06

What action results from a failure to exchange information due to excessive transmission attempts when using an ARQ mode?
- A.The checksum overflows
- B.The connection is dropped (correct answer)
- C.Packets will be routed incorrectly
- D.Encoding reverts to the default character set
WhyExcessive transmission attempts that fail to exchange information in an ARQ mode result in the connection being dropped. When repeated retransmission attempts in an ARQ session keep failing to successfully exchange a packet, the protocol gives up and the connection is dropped rather than retrying forever, answer B. Excessive retries don't cause a checksum to overflow, don't misroute other packets, and don't force a fallback to a different character set, so A, C, and D describe unrelated failure modes.
