B,C.YoushouldalwayschangetheSSIDandtheadministratorpasswordonawirelessrouter.

On Monday, you log into your computer at work, but you are not able to access any network resources. You run ipconfig and see that your IP address is 169.254.18.53. What is the most likely cause of the problem? A. The DNS server is down. B. The DHCP server is down. C. The NAT server is down. D. Your default gateway is set incorrectly.

B. The DHCP server automatically configures clients with TCP/IP information. If the server is not able to provide information, your computer will automatically configure itself with an APIPA address, which starts with 169.254.

This question refers to the scenario at the end of the chapter, in "Configuring a Small Office Network." When connecting client computers to the network, what password do they need to enter? A. tpg$2015 B. 7ygH$2p* C. Tx$pr4y2 D. No password is required.

C. The network password for clients to use is Tx$pr4y2

Your friend Michael is setting up a wireless network and asks you which security option he should choose to make the network the most secure. What do you suggest? A. WEP B. WPA C. WPA2 D. NAT

C. WPA2 is the most secure wireless security protocol in use today.

Your friend Maria asks you which of the following are the most secure. What do you tell her? A. 802.11n B. Infrared C. Cellular D. UTP

D. Wired connections are more secure than wireless ones, and the only wired connection listed is UTP.

Your friend Barbara needs to set up an Internet connection. In this scenario, which of the following options will give her the best speed? (Choose two.) A. Cable Internet B. DSL C. Satellite D. Cellular

A, B. Cable Internet and DSL are the two fastest broadband options listed. Both satellite and cellular are slower.

You are configuring a computer to participate on a network. Which of the following are mandatory? (Choose two.) A. IP address B. Default gateway C. DHCP server D. Subnet mask

A, D. For network communications on a TCP/IP network, an IP address and a subnet mask are required. If you want to communicate outside your network, a default gateway is also required. DHCP servers automatically assign clients IP configuration information.

Which one of the following addresses is considered a private IP address? A. 192.168.100.101 B. 168.192.100.101 C. 19.21.68.100 D. 172.15.100.101

A. Addresses that are in the 192.168.x.x range are private IP addresses, as are those in the 10.x.x.x range and the 172.16.x.x-172.31.x.x range.

Which of the following connectivity options gives you the best mobility? A. Cellular B. Wireless C. Wired D. Broadband

A. Cellular networks give you the best mobility, with a range of up to several miles. Even then, unless you go out of the range of a tower completely, you will be handed over to the next cell tower.

What command would you use on a Mac to determine your TCP/IP configuration information?

A. The ifconfig command is used on Macs and in Linux and UNIX to show your IP address and other TCP/IP configuration information.

You are configuring a wireless router to let clients get on the Internet while using private IP addresses. In this scenario, which of the following services do you need to make sure is enabled on the router? A. DHCP B. DNS C. NAT D. APIPA

C. Network Address Translation (NAT) is a service run on a router that translates private IP addresses into a public IP address, so you can get on the Internet.

You configured a wireless network for your neighbor, and he wants to implement additional security measures beyond the standard wireless encryption. What options does he have? (Choose two.)

B, D. Two additional security options are disabling SSID broadcasts and using MAC filtering. Neither is a true security method that will keep determined hackers off your network, but they will keep casual attackers at bay.

You need to set up a wireless network. Which standard will give you the highest speed? A. 802.11a B. 802.11ac C. 802.11g D. 802.11n

B. The 802.11ac standard is the fastest one available on the market today. In this list, 802.11n is the next fastest, followed by 802.11g and then 802.11a.

This question refers to the scenario at the end of the chapter. Your friend wants the tax prep agents to be able to let their clients connect their wireless devices to the network. Which password should she tell the agents to give to clients? A. 7ygH$2p* B. tpg$2015 C. Tx$pr4y2 D. No password is required.

B. The guest network password for clients to use is tpg$2015.

Of your internal network connection options, which one can provide the fastest speeds? A. UTP B. Fiber C. Infrared D. 802.11n

B. Wired connections in general are faster than wireless ones, and fiber-optic cable can provide much faster speeds than copper cable can.

Which one of these connection types has the longest delay? A. Wireless B. Infrared C. Wired D. Cellular

D. Cellular has the longest delay, because the signal needs to travel the farthest distance

You have decided to retire to a remote mountain cabin and write books. You need an Internet connection to send material to your publisher. What is the option most likely to work for you?

D. If you are in a remote location, it's very possible that satellite is the only option that will work for you.

You have a scenario where you need to disable the guest network on your wireless router. You try to log in, but your password does not work. After several attempts you realize you forgot your password. What can you do? A. Use the password reset option in your router configuration utility. B. Unplug the router and plug it back in. C. Use the default password of admin. D. Hold the reset button down for 30 seconds to reset the router.

D. Wireless routers will have a reset button on their bottom or back. Press and hold the button for about 30 seconds and the router will reset to factory specifications. If you never changed the password, then using admin would work, but I am hoping you changed the password!
