Question 08
A layer 3 device such as a router essentially breaks down a larger Broadcast Domain into two or more smaller broadcast domains. True False
Question 09
A layer 2 switch is connected to four computers A, B, C, and D. The switch's switching table is fully populated (i.e. no entries are missing). If A sends a frame destined for C, the switch will:
forward the frame to D but filter it to A and C
forward the frame to C but filter the frame to A, B, and D
forward the frame to C, B, and D but not A as it is the source
forward the frame to A, B, C, and D and only C will respond as the frame is destined to it.
Question 10.5 Switches send UNICAST Frames to all ports (except incoming) only when destination address is not present in their switching table. True False
Question 11 When multiple switches are present in a single network, a layer 2 switch knows only where to send an incoming frame next. It does not know the entire path the frame may eventually take. True False
Question 08 True, router helps to break broadcast domains by restricting the flow of broadcast message within a subnet.
Question 09 forward the frame to C but filter the frame to A, B, and D
Question 10.5 True. If the destination address is known then switch selectively forwards the frame to appropriate destination.
Question 11 True, layer 2 switch maintains forwarding table corresponding to the mac-address to decide the next node to forward frame based on the mac address.

2) IP and MAC addressing. True or False. One point for each correct answer, zero points for each incorrect answer. Many of the questions refer to the following network consisting of three 10Mbps Ethernet segments, one switch, and one router. Assume all ARP tables are up-to-date unless otherwise stated. a) Consider a network consisting of Ethernets, hubs, switches, and routers. Suppose one of the hubs is replaced with a switch. Then the network administrator must redefine some IP addresses. True...

3. Suppose there is exactly one packet switch (or router) between a sending host and a receiving host. The transmission rates between the sending host and the switch and between the switch and the receiving host are R1 = 1Mbps and R2 = 2Mbps, respectively. Assuming that the switch uses store-and-forward packet switching, what is the total end-to-end delay to send a packet of length 18000bits? Assume that the propagation speed is 2 * 108 meters/sec, the distance between source...

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...
