1. You are troubleshooting a computer that is having connectivity issues. You use ipconfig and determine that it has an address of 169.254.4.7. What is the problem? A. DNS is not working. B. DHCP is not working. C. The network location is set to private. D. The network location is set to public. |
B. An address starting with 169.254 is an APIPA address, and a DHCP client assigns itself an APIPA address when it doesn’t receive a response from a DHCP server. DNS is used for name resolution and does not assign APIPA addresses. The network location is unrelated to how IP addresses are assigned.

2. Your organization is planning on implementing DirectAccess so that users can access the organization’s network when working from home. Of the following choices, what must be included in the plan?
A. IPv6 B. WINS C. HomeGroups D. Preferred wireless settings |
A. DirectAccess requires IPv6, so IPv6 must be implemented to support it. WINS is used for NetBIOS name resolution but is not needed for DirectAccess. HomeGroups are used to share information among users within small workgroup but are not related to DirectAccess. Preferred wireless settings are not needed for DirectAccess.

3. Your network uses IPv6 addresses. Of the following choices, what is a valid IPv6 address?
A. 2000:0021:4137:0000:006C:0000:01E5 B. 2000:0021:0:4137:0:6C:0:0:1E5 C. 2000:21:4137:0:6C::1E5 D. 2000:21:4137::6C::1E5 |
C. An IPv6 address includes eight groups of four hexadecimal characters but can be shortened by eliminating leading zeroes and using zero compression with a single set of double colons. Only seven sets of hexadecimal characters without double colons are not valid. Nine sets of characters are not valid. An IPv6 address cannot use two double colons. |

4. You are troubleshooting a Windows 8.1 computer. It needs an IPv6 address to connect to an Internet resource, but you’re getting an error indicating that it doesn’t have an IPv6 address. Using ipconfig, you’ve verified it has an IPv6 of FE8 : 21 : 137 :: 6C : 1E5. What is the most likely problem?
A. The computer isn’t assigned an anycast address. B. The computer isn’t assigned a global unicast address. C. The computer isn’t assigned a link local address. D. The computer isn’t assigned a unique local address. |
B. The most likely problem is that the computer isn’t assigned a global unicast IPv6 address. The assigned address starts with FE80, indicating it is a link local unicast address. An any- cast address is not used for Internet access. Link local and unique local addresses are not used for Internet access.

5. You are troubleshooting a Windows 8.1 client that is unable to connect to most resources on the network. After troubleshooting it you realize you can successfully ping the IP address of some resources but it fails when you try to ping the name. What is the most likely problem?
A. DHCP B. DNS C. Default gateway D. An APIPA address is assigned. |
B. The most likely problem is DNS because the symptoms indicate that name resolution is not working when the name is pinged and DNS is the only one of the options provided that performs name resolution. DHCP provides an IP address and other TCP/IP configuration information. The default gateway provides a path to other networks through a router. An APIPA address is used when DHCP cannot be reached.

6. Your organization includes over 100 computers configured in a domain. What would these computers use for name resolution? A. DHCP B. DNS C. Domain controller D. WINS |
B. DNS is used for hostname resolution in a domain. DHCP is used to assign IP addresses. Domain controllers are needed in a domain and DNS is required within a domain, but domain controllers do not provide name resolution. WINS is used for NetBIOS name resolution, but NetBIOS names are used less and less, so a WINS server might not be needed. |
|
|
7. Which one of the following commands can you use to see whether a DNS server can resolve a hostname to an IP address?
A. ipconfig B. nslookup C. ping D. tracert |
B. The nslookup command is used to check DNS issues, and it can verify a host record exists on a DNS server. ipconfig is used to check TCP/IP configuration on the local computer. ping is used to verify connectivity. tracert is used to show routers in the path between two systems.
|
|
|
8. You suspect that the DNS resolver cache has incorrect entries. What can you use to remove the entries?
A. ipconfig B. nslookup C. ping D. Disable DHCP |
A. The ipconfig /flushdns command can be used to remove entries from the DNS resolver cache. NSlookup can be used to verify if DNS has the correct entries, but it doesn’t affect the DNS resolver cache on the local computer. Ping is used to check connectivity. Dis- abling DHCP won’t affect the DNS resolver cache.

9. A Windows 8.1 computer has a DHCP lease. The DHCP was recently modified with new information and you want the computer to get a new lease. What should you use?
A. APIPA B. nslookup C. ping D. ipconfig |
D. The ipconfig /release and ipconfig /renew commands can be used to release and renew a lease from a DHCP server. An APIPA address is assigned when a DHCP client doesn’t receive an IP address from DHCP. nslookup and ping are not used to get DHCP leases.

10. A user is connecting her home computer directly to the Internet through her ISP. She doesn’t have a home network and her computer is assigned an IP address from the ISP. What type of network location profile should she use?
A. Private B. Public C. Domain D. IPv6 |
B. The computer is connected directly to the Internet with a public IP address, so it should use the public network location for the best security. The private network location is used for a home or work network when the computer is not connected directly to the Internet. A domain network location is used when the computer is connected to the domain. IPv6 is not a network location.

11. Of the following choices, what is the easiest way to disable Network Discovery on a Windows 8.1 system so that other users cannot see it? A. Disable the firewall. B. Create a rule in the firewall. C. Select the private network location. D. Select the public network location. |
D. Selecting the public network location disables Network Discover and is the easiest way to do so. Disabling the firewall will not disable Network Discovery and is not recommended. It is not necessary to create a rule in the firewall because rules already exist. Network Discovery is enabled by default in the private network location. |
|
|
12. A user has configured a home network with a wireless router and three internal computers. Which network location should he choose when setting up networking for a Windows 8.1 computer?
A. Domain B. Internal C. Public D. Private |
D. The private network location is used for a home or work network and is appropriate here. A domain network location is used when the computer is connected to the domain. Internal is not a network location choice. Public should be selected if the computer is in a public place such as coffee shop or connected directly to the Internet with a public IP address.

13. You are running Windows 8.1 on a public network and want to share some files with a friend running Windows 7. You try to create a HomeGroup but can’t get it to work. What is the most likely reason why this is not working?
A. HomeGroups are not available for Windows 7. B. HomeGroups can only be created in a public network. C. HomeGroups can only be created in a domain network. D. HomeGroups can only be created in a private network. |
D. HomeGroups can only be created when the private network location is used. They are available in for both Windows 7 and Windows 8.1 systems. You cannot create them when a public network or domain network is selected.

14. A user has recently joined a HomeGroup and realizes that documents are being shared that she doesn’t want shared. What can the user do to stop sharing these documents but access HomeGroup resources from other computers?
A. Leave the HomeGroup. B. Change the Media Device section to Off. C. Change the Documents section to Not Shared. D. Change the Files section to Not Shared. |
C. By changing the Documents section to Not Shared, the user ensures that document files in the Documents library will no longer be shared. If the user leaves the HomeGroup, she will not be able to access HomeGroup resources on other computers. Changing the Media Devices section affects streaming media but not document files. HomeGroups do not have a Files section.
