QUESTION 17 We assume that a LAN network includes 7 hosts (A, B, C, D, E. Fand G) which are connected by a switch. The contents of the switch's CAM table is as follows: (Port 1. Host A) - (Port 2. Host B) - (Port 3. Host - Port 4, Host D) - Port S. Hosta-Port 6, Host F) - (Port 7. HostG), Also, we assume that there is/are one or many host(s) that has/have sent fake...
