You have a Windows Server 2008 computer at the corporate office and a Windows Server 2008 computer at a remote site. You want to configure the routing on the server at the branch office. What should you do?

	A.	Install the Routing and Remote Access role and enable the IPv4 LAN routing.

You have a Windows Server 2008 server. You need to add a new static route to the routing table on the server. The new route is to the network ID 192.168.126.0 with a subnet mask of 255.255.255.0, using the default gateway of 192.168.125.1. What command do you need to execute?

	A.	`route -p 192.168.126.0 mask 255.255.255.0 192.168.125.1 metric 2`
	B.	`route add 192.168.126.0 mask 255.255.255.0 192.168.125.1 metric 2`
	C.	`route add 192.168.126.0 255.255.255.0 192.168.125.1 metric 2`
	D.	`route add 192.168.126.0 mask 255.255.255.0 gateway 192.168.125.1 metric 2`

You have a network with several subnets. Windows Server 2008 routers are used to connect the subnets. You need to configure a static route. The static router must not be deleted from the routing table if the computer is restarted. Which of the following parameters should you use with the route command?

	A.	`/f`
	B.	`/s`
	C.	`/r`
	D.	`/p`

You have a server that runs Windows Server 2008. You need to prevent the server from establishing communication sessions to other computers by using TCP port 21. What should you do?

	A.	From Windows Firewall, add an exception.
	B.	From Windows Firewall, enable the Block All Incoming Connections option.
	C.	From the Windows Firewall with Advanced Security snap-in, create an inbound rule.

You have a Windows Server 2008 computer. You want to disable all incoming connections to the server. What should you do?

	A.	From the Services snap-in, disable the Server service.
	B.	From the Services snap-in, disable the Net Logon service.
	C.	Disable the Windows Firewall with Advanced Security.
	D.	From the Windows Firewall, enable the Block All Connections option on the Domain Profile.

Your internetwork consists of seven subnets. All subnets are connected by Windows Server 2008 computers with RRAS. Nonpersistent demand-dial connections have been configured. You do not want to be burdened with updating the routing tables, and you want any changes to the network topology to be propagated immediately. Which of the following routing options should you implement?

	A.	Static routes
	B.	ICMP
	C.	OSPF

The network consists of three different subnets. Dynamic routing is being implemented on three multihomed computers running Windows Server 2008 on which Routing and Remote Access has been enabled. You open the Routing and Remote Access console on the first server and configure the computer for LAN routing. You select New Routing Protocol from the General node of the IP Routing node, and you choose RIP version 2 for Internet Protocol from the New Routing Protocol dialog box. What should you do next?

	A.	Add the IP address of the DHCP server to the properties dialog box for the DHCP Relay Agent.
	B.	Add the interface that RIP will run, using the RIP node.
	C.	Use the `route` command to configure the routes to the remote subnets.
	D.	Use the `route` command to delete all static routers from the routing tables.

You are the network administrator for your company. All servers are running Microsoft Windows Server 2008. Several of the servers are configured as routers with RIP enabled. You want to eliminate any routing loops from occurring. You open the properties window for the interface assigned to the RIP protocol and select the Advanced tab. Which of the following options meets these requirements?

	A.	Enable split-horizon processing.
	B.	Enable triggered updates.
	C.	Process host routes in received announcements.

You have a network with several Windows Server 2008 computers. Your company has opened a new remote office. You are in charge of configuring a two-way demand-dial connection between your corporate office and the new remote office. You configure the demand-dial routers with the following settings:

Corporate Office Router Settings:
- Interface: SRV02_Public
- User Account: SRV02
- Calling Number: 555-3434
Site Router Settings:
- Interface: SRV01_Public
- User Account: SRV01
- Calling Number: 555-1212

When you go to test your configuration, neither of the routers can establish a connection. What should you do?

	A.	Change the interface name on the router in the head office to SRV01_Public.
	B.	Change the demand-dial interface name on each router to match the name of the user account on the remote answering router.
	C.	Change the interface name on the router in the branch office to SRV02_Public.
	D.	Change the names assigned to the user accounts on each router so they are identical.
