Which end hosts are in the same subnet as the host 154.246.37.104/21?  Select all that apply.

Which of the following network is susceptible to a broadcast storm of the entire network if A sends huge amount of broadcast frames onto the network?  Select all that apply.

Match each of the network diagram to the correct number of collision and broadcast domains. Network 1 Network 2 Network 3 Network 4

Case Study: Use the network diagram below and Appendix A to help you answer the question. IMPORTANT• Assume that all the switches already learn about all the nodes in the network and that the CAM table entries do not expire during the time that the communications took place.• The ARP table of each node and the routers will reflect the cumulative changes from previous events as each node communicates with one another and does not expire during the time that the communications took place.• Starting ARP tables for each node can be found in the Appendix A.  You need to use the Appendix to keep track of any changes to the ARP tables yourself, as each event occurs.   Bigger view of network diagram and starting ARP tables. Overview: Questions in the case study can be generic questions or questions related to one of the events. Event 1: A talks to B Event 2: E talks to D Event 3: D talks to C Event 4: F talks to A Event 5: B talks to C Event 3: D talks to C, based on the state of the ARP tables after events 1 and 2, which type of frames will R3 eventually receive from R2, and what would be populated in each slot X?

Which of the following network is susceptible to sniffing attack by other end hosts on the network when A sends a unicast frame to D and vice versa?  Select all that apply. Assume that all the CAM table are populated with all the hosts on the local network.

Event 1: A talks to B Event 2: E talks to D Event 3: D talks to C Event 4: F talks to A Event 5: B talks to C Event 1: A talks to B, based on the starting ARP tables in Appendix A, what would be the first frame that A sends out, and what would be populated in each slot X?

Host A’s TCP connection has the following parameters for congestion control: MSS Size = 1500 bytes cwnd = 10,000 bytes ssthresh = 8000 bytes   Suppose the latest RcvWin received = 40,000 bytes, then after a period of time, a timeout event occurs, what would be the sending Window Size for Host A at this point?
