QUESTION 16
You have a DHCP server that runs Windows Server 2008 R2. You need to reduce the size of the DHCP
database.
What should you do?
A. From the DHCP snap-in, reconcile the database.
B. From the folder that contains the DHCP database, run jetpack.exe dhcp.mdb temp.mdb. C. From the properties of the dhcp.mdb file, enable the File is ready for archiving attribute.
D. From the properties of the dhcp.mdb file, enable the Compress contents to save disk space attribute.
Correct Answer: B
Explanation/Reference:
Correct answer(s): B
To compact the DHCP database:
CD %SYSTEMROOT%SYSTEM32DHCP NET STOP DHCPSERVER
JETPACK DHCP.MDB TMP.MDB NET START DHCPSERVER
In the examples above, Tmp.mdb is a temporary database that is used by Jetpack.exe. Wins.mdb is the
WINS database. Dhcp.mdb is the DHCP database.
Jetpack.exe compacts the WINS or DHCP database by doing the following:
-Copies database information to a temporary database file called Tmp.mdb.
-Deletes the original database file, Wins.mdb or Dhcp.mdb.
-Renames the temporary database files to the original filename.

QUESTION 17
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?
A. From the DHCP snap-in, modify the bindings to associate only LAN1 with the DHCP service. B. From the DHCP snap-in, create a new multicast scope.
C. From the properties of the LAN1 network connection, set the metric value to 1. D. From the properties of the LAN2 network connection, set the metric value to 1.
Correct Answer: A
Explanation/Reference:
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 18
Your network contains a server named Server1 that runs Windows Server 2008 R2. Server1 is configured as a DNS server.

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

QUESTION 19
Your network uses IPv4.
You install a server that runs Windows Server 2008 R2 at a branch office. The server is configured with two network interfaces.
You need to configure routing on the server at the branch office.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.) A. Install the Routing and Remote Access Services role service.
B. Run the netsh ras ip set access ALL command.
C. Run the netsh interface ipv4 enable command.
D. Enable the IPv4 Router Routing and Remote Access option.
Correct Answer: AD
Explanation/Reference:
Correct answer(s): A, D

QUESTION 20
Your company has an IPv4 Ethernet network.
A router named R1 connects your segment to the Internet. A router named R2 joins your subnet with a segment named Private1. The Private1 segment has a network address of 10.128.4.0/26. Your computer named WKS1 requires access to servers on the Private1 network. The WKS1 computer configuration is as shown in the following table.
WKS1 is unable to connect to the Private1 network by using the current configuration. You need to add a persistent route for the Private1 network to the routing table on WKS1.
Which command should you run on WKS1? A. Route add -p 10.128.4.0/22 10.128.4.1
B. Route add -p 10.128.4.0/26 10.128.64.10
C. Route add -p 10.128.4.0 mask 255.255.255.192 10.128.64.1
D. Route add -p 10.128.64.10 mask 255.255.255.192 10.128.4.0
Correct Answer: C
Explanation/Reference:
Correct answer(s): C
For example, to add a static route to the 10.0.0.0 network that uses a subnet mask of 255.0.0.0, a gateway of 192.168.0.1, you type the following at a command prompt:
route add 10.0.0.0 mask 255.0.0.0 192.168.0.1
