Review of Chapter 11: Layer 3 Protocols

Rules 1.Members are divided into teams. 2.Each team takes turns answering the questions. 3.Only one person may speak for the team. 4.The team may elect to answer the question WITHOUT seeing the multiple choice answers. If they are right, they receive 5 points. If they are wrong, 5 points are deducted. 5.If the team WANTS to see the multiple choice answers, they are awarded 3 for a correct answer and if they are wrong, 3 points are deducted.
