(iii) Which of the statements about protocol architecture are CORRECT? Check all that apply: [2 pts] a. Packet network protocols are structured into layers such as ISO 7-layer or IP 4-layer. b. Protocol syntax refers to structure and information fields in control and data packets. c. Protocol semantics refers to actions to be performed on each packet. d. Algorithms for functions such as routing are not a part of the core protocol specification e. Routing algorithms used in the IP spec include Djikstra and Bellman-Ford. (iv) Given an IP CIDR prefix 10.0.0.0/18, which of the following statements is TRUE? [2 pts] 18 a. The prefix length is 14 and the remaining 18 bits can be used to represent 2¹8 IP addresses within the prefix. 14 b. The prefix length is 14 and the remaining 14 bits can be used to represent 2¹4 IP addresses within the prefix. c. IP addresses inside the prefix share the bottom 14 bits. 14 d. The prefix length is 18 and the remaining 14 bits can be used to represent 2¹4 IP addresses within the prefix. (v) Which of the following are CORRECT for BGP. Check all that apply: [2pts] a. A BGP router sometimes picks the path with the least number of router hops. b. A BGP router always picks the path with the least number of AS hops. c. An AS will announce routes learned from its customers to its peers. d. If an AS learns of 5 different routes to a destination prefix, it will announce all 5 routes to its neighbors. e. BGP requires strictly hierarchical address allocation using CIDR. (iii) Which of the statements about protocol architecture are CORRECT? Check all that apply: [2 pts] a.
