1. (56pts) Do the Wireshark exercise attached below (7 questions, 8pts each). 2. (14pts) Do some investigation on Management Information Base (MIBs) that are used in SNMP protocol and explain them briefly 3. (20pts) Suppose Host A sends two TCP segments back to back to Host B over a TCP connection. The first segment has sequence number 90; the second has sequence number 110 (a) How much data is in the first segment? (b) Suppose that the first segment is lost but the second segment arrives at B. In the acknowledgment that Host B sends to Host A, what will be the acknowledgment number? 4. (10pts) Suppose the IEEE 802.11 RTS and CTS frames were as long as the standard DATA and ACK frames. Would there be any advantage to using the CTS and RTS frames? Why or why not? 1. (56pts) Do the Wireshark exercise attached below (7 questions, 8pts each). 2.
