A 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?
- The switch connection speed was set to 10/100 Mb/s.
- The NIC wake-on-LAN setting is misconfigured.
- Hibernation mode is causing the NIC to shutdown unexpectedly.
- The NIC is configured to use both IPv4 and IPv6 at the same time.
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.

A 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?
- Connect with a VPN.
- Change the network location profile to public.
- Change the Windows firewall settings.
- Manually configure an IP address, subnet mask, and default gateway.
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.

A small company is considering moving many of its data center functions to the cloud. What are three advantages of this plan? (Choose three.)
- The company only needs to pay for the amount of processing and storage capacity that it uses.
- Cloud services are billed at a fixed fee no matter how much processing and storage are used by the company.
- Cloud services enable the company to own and administer its own servers and storage devices.
- The company can increase processing and storage capacity as needed and then decrease capacity when it is no longer needed.
- Single-tenant data centers can easily grow to accommodate increasing data storage requirements.
- As the amount of data that the company uses increases, it becomes impractical for the data to be stored and processed in a single-tenant data center.
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.

19. Question
1 points
A 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?
- Attempt to ping the default gateway.
- Check the NIC LED lights.
- Test that DNS is operating correctly.
- Activate Network Discovery and File Sharing.
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.

A 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?
- Verify that DNS name resolution is operating properly.
- Inspect the network patch cable for wear or breaks.
- Check Network Connection Details in the Windows GUI for the appropriate network connection.
- Check the link LED on the NIC.
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.

A 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.)
- The wireless router is not broadcasting the SSID.
- The laptop has not received an IP address from the wireless router.
- The wireless router is set to mixed mode.
- The network does not support the wireless protocol in use by the laptop.
- The laptop must be configured with the office workgroup name.
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.

A 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.)
- The Windows domain or workgroup name that is configured on the computer is incorrect.
- The target web server is down.
- The computer has been assigned a static IP address.
- DNS service is unavailable on the customer network.
- The HTTP protocol is not working properly on the target server.
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.
