5.3.11 Practice Questions

Angela is the network administrator for a rapidly growing company with a 100BaseT network. Users have recently complained about slow file transfers. While checking network traffic, Angela discovers a high number of collisions. Which connectivity device would BEST reduce the number of collisions and allow future growth?

Switch

You have a network that's connected using a physical star topology. One of the drop cables connecting a workstation has been removed. Which of the following BEST describes the effect that this will have on network communications?

All devices except the device connected with the drop cable will be able to communicate.

During a network infrastructure upgrade, you replaced two 10 Mbps hubs with switches and upgraded from a Category 3 UTP cable to a Category 5e. During the process, you accidentally cut the Cat 5e patch cable that stretches from the network printer to the upgraded switch. What is the impact on your network?

All network nodes except the printer will be available.

You are implementing a SOHO network for a local business. The ISP has already installed and connected a cable modem for the business. The business has four computers that need to communicate with each other and the internet. The ISP's cable modem has only one RJ45 port. You need to set up the network within the following parameters: -You must spend as little money as possible. -You must not purchase unnecessary equipment. -Computers need to have a gigabit connection to the network. -New devices should not require management or configuration. You examine each computer and notice that only one of the four computers has a wireless NIC. They all have Ethernet NICs. What should you purchase?

An unmanaged switch and CAT 5e cabling.

You have a network that's connected using a full physical mesh topology. The link between Device A and Device B is broken. Which of the following BEST describes the effect that this will have on network communications?

Device A will be able to communicate with all other devices.

You have just connected four new computer systems to an Ethernet switch using spare patch cables. After the installation, only three systems are able to access the network. You verify all client network settings and replace the network card in the failed system. The client is still unable to access the network. Which of the following might you suspect is the real cause of the problem?

Failed patch cable

You are moving a client to a new location within an Ethernet network. Previous to the move, the client system did not have difficulty accessing the network. During the relocation, you attach patch cables from the client system to the wall jack and from the patch panel to the switch. Once connected, you do not get a link light on the network card or the switch. You swap out the cable running between the patch panel and the switch with a known good one, but you still cannot connect. Which of the following might you suspect is the problem?

Failed patch cable between the client system and the wall jack

Upon conducting a visual inspection of the server room, you see that a switch displays LED collision lights that are continually lit. You check the LED on the corresponding workstation and see that it is flashing rapidly even though it is not sending or receiving network traffic at that time. What is the cause of the network collisions?

Faulty network card

You have a network that's connected using a physical bus topology. One of the cables that connects a workstation to the bus breaks. Which of the following BEST describes the effect that this will have on network communications?

No devices will be able to communicate.

A user from the sales department calls to report that he is experiencing problems connecting to the sales file server. All users in the sales department connect to this server through a single Ethernet switch. No other users have reported problems connecting to the sales server. Which of the following troubleshooting actions are you MOST likely to perform first?

Replace the network card in the user's computer.
