Question 1 of 24
1. Question
1 pointsA user notices that the data transfer rate for the gigabit NIC in the user computer is much slower than expected. What is a possible cause for the problem?Correct
Incorrect
For optimum performance, both ends of the conection must be set to the fastest possible speed. If the switch end was set to 10/100 Mb/s the top speed of the connection would be 100 Mb/s.Hint

5. Question
1 pointsA technician is configuring the channel on a wireless router to either 1, 6, or 11. What is the purpose of adjusting the channel?Correct
Incorrect
Channels 1, 6, and 11 are selected because they are 5 channels apart. thus minimizing the interference with adjacent channels. A channel frequency can interfere with channels on either side of the main frequency. All wireless devices need to be used on nonadjacent channels.Hint

Question 7 of 24
7. Question
1 pointsA business traveler connects to a wireless network with open authentication. What should the traveler do to secure confidential data when connecting to the business services?Correct
Incorrect
A VPN is used to form a secure tunnel across a public network. This technology allows users to communicate over an insecure network and yet keep data confidential. Changing the network location profile will modify firewall settings on a computer but not increase the confidentiality of data crossing a network. Modifying the IP address, subnet mask, and default gateway will not change the confidentiality of data transmitting on a network.Hint

Question 11 of 24
11. Question
3 pointsA small company is considering moving many of its data center functions to the cloud. What are three advantages of this plan? (Choose three.)Correct
Incorrect
Cloud computing offers many advantages to the company. Since the cloud data storage and processing facilities are owned by third-parties, the company doesn’t need to be concerned about how it will handle increasing data storage and processing demands with its own data center equipment. The company can easily increase or decrease processing power and storage capacity based on need. Also, cloud services are billed by usage, so the company doesn’t have the costs of supporting its own expensive data center that is not always used to maximum capacity.Hint

Question 17 of 24
17. Question
1 pointsA user cannot access the network. While the technician is checking the computer, the other users on the same network report that they are having the same problem. Further investigation shows that the LED lights on each NIC are not lit. What should the technician do next?Correct
Incorrect
Unlit LED indicators on multiple computers in the same network is a possible symptom of a network problem. If the NIC is not attached to the network, pings and commands like nslookup will fail. It is best to escalate the problem to the network administrator for further investigation.Hint

Question 19 of 24
19. Question
1 pointsA technician is investigating a report that a computer is unable to access network resources. The technician discovers that the computer has an IP address of 169.254.27.168. What is a logical first step in diagnosing this problem?Correct
Incorrect
An IP address of 169.254.x.x indicates that the computer has not been able to receive an IP address from DHCP. There are many possible causes for this, but it is important to first check to see if the computer has any connection to the network at all. The LED lights on the NIC will indicate this. If the device does not have a valid network address from DHCP, pinging the default gateway or testing DNS will fail. This should already be apparent from the IP address, so this test offers no additional information. Similarly, DNS will also fail. This problem is not related to the Network Discovery and File Sharing settings.
A logical next step would be to inspect the cable if no LED lights are lit.

Question 20 of 24
20. Question
1 pointsA Windows 7 computer is unable to reach a mapped drive on a file server that is on another network within the organization. Further investigation shows that the user is able to use a printer that is connected to the same network as the computer. Which action should the technician perform next?Correct
Incorrect
Network Connection Details in the Windows GUI allows the technician to check the IP addressing information of the computer. From the symptoms described, a good theory is that the default gateway setting is incorrect. Because the computer can access the printer, it is not necessary to check the cable or link lights to gather information to solve this problem. Finally, DNS is not implicated, because drive mappings on file servers within the organization are not assigned URLs.Hint

Question 21 of 24
21. Question
2 pointsA user has taken a personal laptop to work. The laptop is unable to discover the name of the office wireless network. What are two potential causes of this problem? (Choose two.)Correct
Incorrect
The laptop could be using an older NIC that uses a protocol not supported by the network. This would be especially likely if the wireless router was not configured in mixed mode. In addition, the wireless router could have SSID broadcasting deactivated. In either case, the computer would not be able to discover the network name. An IP address or workgroup configuration is not required to see the network name.Hint

Question 22 of 24
22. Question
2 pointsA network technician attempts to ping http://www.example.net from a customer computer, but the ping fails. Access to mapped network drives and a shared printer are working correctly. What are two potential causes for this problem? (Choose two.)Correct
Incorrect
A ping would fail if the destination device was not operational. It would also fail if the DNS server was unavailable to convert the URL to an IP address. The fact that a computer had a static IP address is not a factor. Even if the target protocol (HTTP) is not functioning, the server would still respond to a ping.Hint
