TS: Windows Server 2008 Network Infrastructure, Configuring

Question No: 21 – (Topic 1)

You have a DHCP server that runs Windows Server 2008 R2. The DHCP server has two network connections named LAN1 and LAN2.

You need to prevent the DHCP server from responding to DHCP client requests on LAN2. The server must continue to respond to non-DHCP client requests on LAN2.

What should you do?

  1. From the DHCP snap-in, modify the bindings to associate only LAN1 with the DHCP service.

  2. From the DHCP snap-in, create a new multicast scope.

  3. From the properties of the LAN1 network connection, set the metric value to 1.

  4. From the properties of the LAN2 network connection, set the metric value to 1.

Answer: A Explanation: Correct answer(s): A

By default, the service bindings depend on whether the network connection is configured dynamically or statically for TCP/IP. Based on the method of configuration it uses, reflected by its current settings in Internet Protocol (TCP/IP) properties, the DHCP Server service performs default service bindings as follows:

If the first network connection uses a manually specified IP address, the connection is enabled in server bindings. For this to occur, a value for IP address must be configured and the Use the following IP address option selected in Internet Protocol (TCP/IP) properties. In this mode, the DHCP server listens for and provides service to DHCP clients.

If the first network connection uses an IP address configured dynamically, the connection is disabled in server bindings. This occurs when the Obtain an IP address automatically option is selected in Internet Protocol (TCP/ IP) properties. For computers running Windows Server 2008 R2 operating systems, this is the default setting.

In this mode, the DHCP server does not listen for and provide service to DHCP clients until a static IP address is configured.

The DHCP server will bind to the first static IP address configured on each adapter. Note

By design, DHCP server bindings are enabled and disabled on a per-connection, not per- address basis. All bindings are based on the first configured IP address for each

connection appearing in the Network Connections folder. If additional static IP addresses (for example, as set in Advanced TCP/IP properties) are configured for the applicable connection, these addresses are never used by DHCP servers running Windows Server 2008 R2 and are inconsequential for server bindings.

DHCP servers running Windows Server 2008 R2 never bind to any of the NDISWAN or DHCP-enabled interfaces used on the server. These interfaces are not displayed in the DHCP console under the current server bindings list because they are never used for DHCP service. Only additional network connections that have a primary static IP address configured can appear in the server bindings list (or be selectively enabled or disabled there).

Question No: 22 – (Topic 1)

Your network contains an Active Directory domain named contoso.com. The domain contains a server named Server1 that runs Windows Server 2008 R2 Service Pack 1 (SP1). Server1 has the Windows Server Update Services (WSUS) server role installed.

Server1 downloads updates from Microsoft Update every day.

You have an isolated test network that is not connected to the production network.

On the test network, you implement a WSUS server named Server2. Server2 has the same WSUS configuration as Server1.

You need to ensure that Server2 can distribute the same updates as Server1.

Which actions should you perform? (Each correct answer present part of the solution. Choose three.)

  1. On Server2, run wsusutil.exe and specify the import parameter.

  2. On Server1, run wsusutil.exe and specify the export parameter.

  3. On Server2, restore the system state.

  4. On Server1, back up the system state.

  5. Copy the WSUSContent folder from Server1 to Server2.

  1. Configure the IPv6 address as fd00::2b0:d0ff:fee9:4143/8.

  2. Configure the IPv6 address as fe80::2b0:d0ff:fee9:4143/64.

  3. Configure the IPv6 address as ff80::2b0:d0ff:fee9:4143/64.

  4. Configure the IPv6 address as 0000::2b0:d0ff:fee9:4143/64.

Answer: A

Question No: 26 – (Topic 1)

Your network contains an Active Directory domain. The domain contains a DHCP server named Server1. You create a scope named Scope1 on Server1.

You need to prevent unauthorized DHCP clients from receiving addresses from Server1. What should you do?

  1. From the DHCP console, configure filters.

  2. From the Local Security Policy console, modify the network settings.

  3. From the Local Users and Groups console, modify the membership of the DHCP Users group.

  4. From the Netsh tool, change to the DHCP Server context, and then run the initiate auth command.

Question No: 27 – (Topic 1)

Your company has a single Active Directory forest that has six domains. All DNS servers in the forest run Windows Server 2008 R2.

You need to ensure that all public DNS queries are channeled through a single-caching- only DNS server.

Question No: 30 – (Topic 1)

Contoso Ltd. has a single Active Directory forest that has five domains. Each domain has two DNS servers.

Each DNS server hosts Active Directory-integrated zones for all five domains. All domain controllers run Windows Server 2008 R2.

Contoso acquires a company named Tailspin Toys. Tailspin Toys has a single Active Directory forest that contains a single domain.

You need to configure the DNS system in the Contoso forest to provide name resolution for resources in both forests.

What should you do?

  1. Configure client computers in the Contoso forest to use the Tailspin Toys DNS server as the alternate DNS server.

  2. Create a new conditional forwarder and store it in Active Directory. Replicate the new conditional forwarder to all DNS servers in the Contoso forest.

  3. Create a new application directory partition in the Contoso forest. Enlist the directory partition for all DNS servers.

  4. Create a new host (A) record in the GlobalNames folder on one of the DNS servers in the Contoso forest. Configure the host (A) record by using the Tailspin Toys domain name and the IP address of the DNS server in the Tailspin Toys forest.
