question

You administer a network with Windows and Linux servers, and Windows 7 clients. A user calls and indicates that he is unable to access resources on the network. You type ipconfig on the user's computer and receive the following output: Ethernet adapter Local Area Connection : IPv4 address . Subnet Mask . Default Gateway 169 . 254 .1.17 255 . 255 . 0 . 0

answer

Unavailable DHCP server.

question

You have just connected a new computer to your network. The network uses static IP addressing. You find that the computer can communicate with hosts on the same subnet, but not with hosts on a different subnet. No other computers are having a problem. Which of the configuration values would you most likely need to change?

answer

Default gateway Check the default gateway setting on the computer. The default gateway value is used for sending packets to other subnets. If the value is incorrect, then the packets will not be sent to the correct router. In this scenario, the host can communicate with other hosts on the same subnet, meaning that the IP address and subnet mask are correctly configured. The DNS server address is likely not the problem as name resolution is not mentioned in the scenario. In addition, if name resolution were a problem, it could affect access to both local and remote hosts.

question

question

Given that your Windows workstation has Automatic Private IP Addressing (APIPA) implemented using default settings, which of the following TCP/IP addresses could be automatically assigned to the system should your DHCP server go down or become inaccessible?

answer

169.254.1.26 In the event that a DCHP server is not available, Windows workstations can use APIPA to automatically provide themselves with an IP address. The default address range used by APIPA is 169.254.0.1 to 169.254.255.254. Of the options presented, only 169.254.1.26 falls within this range.

question

You manage a network that has multiple internal subnets. You connect a workstation to the 192.168.1.0 subnet which uses the default subnet mask. This workstation can communicate with some hosts on the private network, but not with other hosts. You run ipconfig /all and see the following: Ethernet adapter Local Area Connection : Connection- specific DNS Suffix . : mydomain . local Description . . . Broadcom network adapter Physical Address . : 00 - AA-BB-CC-74-EF DHCP Enabled . . . . . . . No Autoconfiguration Enabled .

answer

Incorrect subnet mask In this example, the network is using a mask of 255.255.255.0 (24-bits), but the workstation is configured to use a mask of 255.255.0.0.

question

You are designing an update to your client's wireless network. The existing wireless network uses 802.11b equipment, which your client complains runs too slowly. She wants to upgrade the network to run at 150 Mbps. Due to budget constraints, your client wants to upgrade only the wireless access points in the network this year. Next year, she will upgrade the wireless network boards in her users' workstations. She has also indicated that the system must continue to function during the transition period. Which 802.11 standard will work best in this situation?

answer

802.11 n is the best choice for this client. Both 802.11 a and 802.11 g each operate at a maximum speed of 54 Mbps. 802.11a isn't compatible with 802.11 b network boards.

question

While troubleshooting a network issue, you successful ping the 127 .0.0.1 IP address. Which of the following is true?

answer

The TCP/IP protocol suite is working correctly on the local computer. The 127.0.0.1 IP address is reserved as the loopback address of the local computer. A successful ping to 127.0.0.1 indicates the TCP/IP protocol suite is working correctly on the local computer.

question

A user reports that he can't browse to a specific Web site on the Internet. From his computer, you find that a ping test to the Web server succeeds. A trace route test shows 17 hops to the destination Web server. What is the most likely cause of the problem?

answer

Incorrect DNS server address In this scenario, a ping test to the Web site succeeds, while accessing the Web site through the browser does not work. Users type host names in the browser to go to Web sites, and host names must be translated to IP addresses by a DNS server. Either the workstation is using the wrong address for the DNS server, the DNS server is not available, or the DNS server does not have an entry for the Web site. Because the ping and trace route tests work, you know that the IP address, subnet mask, and default gateway values are correct.

question

You are designing a wireless network for a client. Your client needs the network to support a data rate of at least 54 Mbps. In addition, the client already has a wireless telephone system installed that operates 2.4 GHz. Which 802.11 standards will work best in this situation? (Select two.)

answer

802.11a 802.11n (good luck find a NEW 802.11a router... )

question

Your home network is connected to the Internet through a 512 Mbps DSL line. Your ISP provided you with a small office/home office (SOHO) router that provides four 100 Mbps Ethernet ports for your home office and one DSL port for connecting the network to the Internet. The SOHO router has a built-in DHCP server that is used to automatically configure workstations with an IP address, default gateway address, and DNS server address. However, today you are unable to access the Internet. The browser reports that it can't find the URLs you are requesting. Using the ipconfig command, you've verified that the workstation is receiving correct IP address parameters. You tried entering tracert 137 .65.1.2 at a command prompt and found that you're able to reach this server on the Internet without any issues. What is causing this problem?

answer

Your ISP's DNS server is down. Because your workstation is able to receive correct IP parameters from the built-in DHCP server, you know that the home office side of the SOHO router is working correctly. The fact that you're able to trace the route from your workstation to a server on the Internet using its IP address indicates that routing is working properly. This, coupled with the browser error message, would indicate that the most likely problem is a down or malfunctioning DNS server. You could test this hypothesis by trying to access a Web site using an IP address in the URL instead of a domain name.

question

You have a small wireless network with less than 50 client computers. You upgraded the hardware on two wireless devices so you can use a better security standard than WEP. Now you need to implement the new security standard. You need the greatest amount of security with the least amount of effort, and without replacing any of the wireless infrastructure. What should you do? (Select two.)

answer

Implement WPA2-AES Configure each client with the same key In this case, implementing WPA2 with AES and using the same pre-shared key on each client provides the greatest amount of security with the least amount of effort, and does not require the replacement of any of the wireless infrastructure. WPA2- Enterprise uses 802.1x for authentication and requires the configuration of an authentication server. WPA2 is more secure than WPA-PSK.

question

Which wireless standard has the highest data transfer rates?

answer

802.11a 802.11n Answer 802.11b 802.11g 802.11 n has the highest data transfer rates, up to (theoretically) 600 Mbps.802.11 a and g have speeds up to 54 Mbps or 108 Mbps when using channel bonding. 802.11 b has speeds up to 11 Mbps.

question

You are troubleshooting connectivity between your computer and the www.widgets.com server whose IP address is 192.168.1.1. Which of the following commands tests connectivity to the device as well as name resolution?

answer

ping www.widgets.com To test both name resolution and communication with the server, use the ping command with the host name. The first step in the ping test is to find the IP address of the specified host. Using ping with just the IP address will not test name resolution. Using nslookup only tests name resolution, it does not test communication with the end device.
