Use the following scenario to answer the 10 questions below. You have 3 networks (A, B, and C) and 2 routers (Y and Z). Network A has an address space of 10.1.1.0/24 and is connected to router Y using the interface 10.1.1.1. Network B has an address space of 192.168.1.0/24 and is connected to router Y using the interface 192.168.1.254. Network C has an address space of 172.16.1.0/24 and is connected to router Z using the interface 172.16.1.1. The diagram below represents these connections and interfaces. Router Y Network A Interface: 10.1.1.1 Network B interface: 192.168.1.254 Router Z Network B interface: 192.168.1.1 Network C interface: 172.16.1.1 1. Computer 1 on network B with IP address 192.168.1.233 wants to send a packet to Computer 2 with IP address 10.1.1.205. On which network is computer 2? Network C Network A Network B Not present

Consider the network shown below. The IP and MAC addresses are shown for hosts A, B, C, and D, as well as for the router's interfaces. Consider an IP datagram being sent from node B to node D. What is the source MAC address on the frame at point (3)? What is the destination MAC address on the frame at point (3)? What is the source IP address of the datagram at point (3)? What is the destination IP address of the datagram at point (3)? What is the source MAC address on the frame at point (4)? What is the destination MAC address on the frame at point (4)? What is the source IP address of the datagram at point (4)? What is the destination IP address of the datagram at point (4)?
Choose the correct answer from the list below: Question 1: Reserved addresses include all addresses except: - 196.128.12.253 - 192.168.1.100 - 10.1.255.254 - 172.16.100.1 Question 2: A /24 subnet has how many IP addresses? - 64 - 512 - 256 - 128 Question 3: A class B network can include addresses from 127.0.0.1 to 192.255.255.255. - True - False Question 4: A broadcast address is the last address in a subnet. - False - True Question 5: In an IP address, the host bits are the leftmost bits, whereas the rightmost bits are the network bits. - False - True Question 6: How many hosts can a /23 network have if you exclude the gateway address and the broadcast address? - 511 - 512 - 510 Question 7: A netmask of 255.255.248.0 in CIDR notation is: - /22 - /21 - /20 - /23 Question 8: The broadcast address of 128.0.1.65/28 is: - 128.0.1.64 - 128.0.1.87 - 128.0.1.79 - 128.0.1.77 Question 9: The layer that deals with packets in the OSI model is: - 1 - 2 - 3 - 7 Question 10: The layer that deals with reliability of the connection in the OSI model is: - 1 - 5 - 3 - 6 - 4 - 2
