Q
  1. You are the network administrator for a small organization that has decided to implement Microsoft Active Directory. Your organization is worried because the budget does not allow them to purchase new hardware for the Active Directory installation. The server room has a UNIX server it uses for file and DNS access. What option can you tell them about that will allow the organization to have Active Directory?

A. Use Microsoft OneDrive to install Active Directory.
B. Install Active Directory on the UNIX system.
C. Subscribe to Azure Active Directory.
D. Tell them that without the new hardware, there is no way to install Active Directory.

A

C. Subscribe to Azure Active Directory.

  1. C. Subscribing to Azure Active Directory allows a small to midsize company to have Active Directory without the need of purchasing new hardware.

Q
  1. You are the network administrator for a midsize company that uses Windows Server 2012 R2 and Windows 10. All Windows 10 machines receive their IP address from DHCP. You have a Windows 10 machine and need to identify its IPv6 address. How can you accomplish this task? (Choose all that apply.)

A. Click Details from the network connection status.
B. Type ipconfig /all at the command prompt.
C. Type ipconfig /view at the command prompt.
D. Choose Properties of My Computer.

A

A. Click Details from the network connection status.
B. Type ipconfig /all at the command prompt.

  1. A, B. You can see what the IPv6 address is by clicking the Details button from the network connection status or by typing ipconfig /all. There is no such command as ipconfig /view, and the My Computer properties will not show IP address configuration information.

Q
  1. You are hired by friends to set up a network in their home. They have four Windows 10 devices in their home that are all connected by a router. There is currently no network in place. They want to be able to share audio and video files among their family members. How can you set up the network? (Choose two.)

A. Install a Windows Server 2012 R2 domain controller.
B. Create a HomeGroup.
C. All audio and video files should be moved to the media library and accessible through HomeGroup.
D. Move all audio and video files to a shared folder on the Windows Server 2012 R2 machine.

A

B. Create a HomeGroup.
C. All audio and video files should be moved to the media library and accessible through HomeGroup.

  1. B, C. Create a new HomeGroup and set the password. Use that password and join all computers
    to the same HomeGroup. By putting all files in the media library, they will be available to all members of the HomeGroup.

Q
  1. You are the network administrator for an organization with two sites, as shown in Figure 9.26. You need to install a new Windows 10 machine into site
  2. Which TCP/IP address can you assign to the new Windows 10 machine?
MAIN BRANCH 
Windows Server 2012 R2
192.168.2.98
255.255.225.224
Gateway 192.168.2.97

SITE_1
IP address
192.168.2.62/27

-Windows 10 system
192.168.2.33
255.255.255.224
Gateway 192.168.2.62

-New Windows 10 System

A. 192.168.2.32
B. 192.168.2.31
C. 192.168.2.41
D. 192.168.2.63

A

C. 192.168.2.41

  1. C. The company’s subnet mask is 255.255.224.0. This subnet mask uses subnet ranges of 32. So, the subnet’s layout is 32–63, 64–95, 96–127, 128–159, 160–191, and 192–223. Now when you subnet, you can’t use the first or last number of any range. The first number represents the network ID, and the last number represents the broadcast. Because the router and the one Windows 10 computer fall within the 32–63 range, your new Windows 10 machine must fall within this range. 32 is the network ID and can’t be used, and 63 is the broadcast and can’t be used. So, the only available addresses are from 33–62, and the only available unused IP address in that range is 192.168.2.41.

Q
  1. You are the network administrator for a large organization that has decided to use IPv6 and DHCP. You want to set up the network so that all Windows 10 systems using IPv6 get all of their information through DHCP including IP address and default gateway. How would you set up the network?

A. Set up a stateful network.
B. Set up a stateless network.
C. Set up DNS to use DHCP.
D. Set Active Directory static IP addresses.

A

A. Set up a stateful network.

  1. A. Stateful is what we currently do today with IPv4. Stateful means that DHCP is going to give our IPv6 clients all of their TCP/IP data (IP address, default gateway, and all DHC Poptions). Stateless configuration means that the clients address is based on the router’s advertisement messages. Clients create their own IP address and default gateway based on the router’s advertisement message and their MAC address. They can still get all of the other DHCP options, but they will not get an IP address and default gateway from DHCP.

Q
  1. You are the network administrator for a midsize company that uses both desktops and laptops. All laptops use Windows 10 and have been connected to a wireless access point. You disable the SSID, and now your laptops can no longer connect to the access point. What do you need to do to allow the laptops to connect?

A. Reboot the laptops.
B. Modify the wireless network connection settings on the laptops.
C. Reboot the access point.
D. Disconnect and reconnect the laptops to the domain.

A

B. Modify the wireless network connection settings on the laptops.

  1. B. You need to change the wireless network connection settings on the laptop to allow these laptop users to connect to the reconfigured access point.

Q
  1. You have a Windows 10 system that is having issues connecting to other machines on the network. You want to see the TCP/IP details to make sure that the user is using DHCP and that the assigned IP address is accurate. What command-line utility and switch can you use to do this?

A. Route Add
B. Ipconfig /FlushDNS
C. Ipconfig /all
D. Tracert

A

C. Ipconfig /all

  1. C. Ipconfig / all shows verbose information about your IP configuration, including your computer’s physical address, the DNS server you are using, and whether you are using DHCP.

Q
  1. You are the network administrator for a midsize company that uses both desktops and laptops. All laptops use Windows 10 and have been connected to a wireless access point that is configured to use Advanced Encryption Standard (AES) security. There is no preshared password key being used. You need to connect a new Windows 10 laptop to the access point. How would you set up the security setting on the laptop?

A. WPA2-Personal
B. WPA2-Enterprise
C. WPA-Personal
D. WAP security

A

B. WPA2-Enterprise

  1. B. When it comes to WPA, there are two versions: WPA2-Personal and WPA2-Enterprise. WPA2-Personal allows you to set up WPA2 by using a shared password key. WPA2-Enterprise allows you to set up WPA2 by using a server for verification. Because all users are using AES with no shared password key, WPA2-Enterprise is the setting that you would choose.

Q
  1. You are the network administrator for a large organization that uses Windows Server 2012 R2 and Windows 10. You have decided to set up a tunnel between two locations. You want to set the tunnel up so that it uses IPv6. What protocol can you use that allows for IPv4 and IPv6 on your network and to use IPv6 with the tunneling?

A. IPv4to6
B. 6v4
C. ISATAP
D. TUNISA

A

C. ISATAP

  1. C. ISATAP is the automatic tunnel addressing protocol providing IPv6 addresses based on the IPv4 address of the end interface (node). The IPv6 address is automatically configured on the local device, and the dual-stack machine can use either its IPv4 or IPv6 address to communicate on the local network.

Q
  1. You are the network administrator for a small organization that has decided to switch the company’s TCP/IP subnet mask. The organization has chosen to use 255.255.255.240. What is the increment for subnet ranges in a 240 subnet mask?

A. 4
B. 8
C. 16
D. 32

A

C. 16

  1. C. On a 240 subnet mask, the ranges go by 16. Because this is a Class C, the ranges would be 16–31, 32–47, 48–63, 64–79, 80–95, 96–111, 112–127, 128-143, 144–159, 160–175, 176–191, 192–207, 208–223, and 224–239. Remember that in a Class C address, these are not all usable. You have to subtract the first number (network ID) and the last number (broadcast).
