| Question 1 | You are designing a simple network for a small publishing company. The company has a single two-story building that houses all 44 employees. The company wishes to be connected to the Internet and an ISDN BRI link will be installed in the coming weeks. The company is using an off-site hosting company to host the corporate Web site. There are five servers located on site, two of which are used for sharing files and printers to the employees, one is used for email, one runs a database server, and the other authenticates logins. All employees have workstations or laptops. The company expects to have 10% more employees within the next two years . Which of the following design decisions would you recommend given this information? (Select two answers, each forms a part of the solution.) -
A. Purchase four 12-port hubs. Uplink three of the hubs to the fourth. Connect the workstations, laptops, and servers to the hubs. -
B. Purchase two 24-port Cisco switches with two uplink ports. Uplink the first switch to the second. Connect the workstations, laptops, and servers to the switches. -
C. Purchase a single 48-port Cisco switch. Connect the ISDN line to the switch's uplink port. Connect the workstations, laptops, and servers to the switch. -
D. Purchase a single 48-port Cisco switch and a 12-port switch. Use the uplink ports on the switches to connect them together. Connect the workstations, laptops, and servers to the switch. -

| Question 39 | Your network consists of four switches, two repeaters, a single router, two subnets, and 160 hosts. Switches one and two are on subnet 192.168.10.0 /25, and switches three and four are on subnet 192.168.10.128 /25. Hosts 192.168.10.5 through 192.168.10.45 are connected to switch one. Hosts 192.168.10.46 through 192.168.10.86 are connected to switch two. Two segments of UTP, connected via a repeater, connect switch one to switch two. Hosts 192.168.10.130 through hosts 192.168.10.170 are connected to switch three. Hosts 192.168.10.171 through hosts 192.168.10.211 are connected to switch four. Switch three is connected to switch four via two segments of UTP cable connected together via a repeater. Switch four is connected via UTP to the router. Switch one is connected to the router. Host 192.168.10.50 cannot ping host 192.168.10.165. Host 192.168.10.70 can ping host 192.168.10.200. Assuming all of the hosts work, which of the following devices could be faulty? (Select all that apply.) |
| Question 40 | You have six switches, 120 hosts, three networks, and one router. Your network configuration can be summarized as follows : Switches Alpha and Beta service hosts on Network 10.10.10.0 /24. This network is connected to interface e0 on the router. The hosts on switch Alpha have IP addresses between 10.10.10.10 and 10.10.10.30. The hosts on switch Beta have IP addresses between 10.10.10.50 and 10.10.10.70. Switch Alpha is connected to switch Beta. Switch Beta is connected to the router. Switches Gamma and Delta service hosts on Network 10.10.20.0 /24. This network is connected to interface s1 on the router. The hosts on switch Gamma have IP addresses between 10.10.20.10 and 10.10.20.30. The hosts on switch Delta have IP addresses between 10.10.20.50 and 10.10.20.70. Switch Gamma is connected to switch Delta. Switch Delta is connected to the router. Switches Epsilon and Omega service hosts on network 10.10.30.0 /24. This network is connected to interface s2 on the router. The hosts on switch Epsilon have IP addresses between 10.10.30.10 and 10.10.30.30. The hosts on switch Omega have IP addresses between 10.10.30.50 and 10.10.30.70. Switch Epsilon is connected to switch Omega. Switch Omega is connected to the router. See Figure 15.1 for a diagram.
