The routed IP network has seven subnets with a mixture of WINS and non-WINS clients. Three of the seven subnets contain WINS servers.

Several users report that they are unable to browse hosts on other subnets. On investigating the reports, you discover that the problem is affecting only non-WINS clients. All clients need to be able to resolve NetBIOS names.

	B.	Enable a WINS proxy on subnets without WINS servers.
	C.	Enable replication between the existing WINS servers.
	D.	Add a DHCP relay agent on each subnet.

You need to ensure that all computers in the Member Servers OU stay up-to-date with the latest software updates. You want updates automatically installed on the member servers. You want to accomplish this with the least amount of administrative effort.

You are troubleshooting a connectivity issue with three users in a small remote office. Clients in the office connect to an RRAS server through a local switch running in Full Duplex mode. The 16-port switch has numbered cable runs that go to each open wire jack at a workstation location. For example, port one on the switch is labeled as going to jack 1A, port two on the switch is labeled as going to jack 1B, and so on.

All three users have a desktop system, a laptop, and a developmental test workstation at their desk. Users one and two have all their systems connected to individual ports; user three has one system connected directly to a wall jack and the other two connected through a hub to the wall jack.

All these clients (except for the Windows 2000 servers and Windows Server 2003 systems) use DHCP. The Windows Server 2003 systems and Windows 2000 servers have manually assigned static IP addresses, but you need to configure these systems to use DHCP and keep their current IP addresses.

You have been asked to configure a DHCP server solution for your environment that allows all clients to obtain an IP address from a server hosting DHCP and that does not allow a single point of failure for addressing. Your configuration must also address your current business model needs, which require you to choose the least expensive option after ensuring no single point of failure. Which of the following is the best solution?

	A.	Deploy two DHCP servers at each location and use a 50/50 address rule for each scope between the two servers. Create one scope for each location. Create the necessary IP address exclusions for the scope on both DHCP servers at each location.
	B.	Deploy three DHCP servers total and use a 33/33/34 address rule for each scope so that each DHCP server has addresses for its local scope and the two remote scopes. Create one scope for each location. Create the necessary client reservations for the scope on each DHCP server.
	C.	Deploy two DHCP servers at each location and use a 50/50 address rule for each scope between the two servers. Create one scope for each location. Create the necessary client reservations for the scope on both DHCP servers at each location.

You decide to test connectivity between the systems at branch one and the default gateway to the company headquarters. You log in at WORKSTATION1, enter PING LOCALHOST, and receive the expected replies. You then ping WORKSTATION2, which is the next client system you’re using for your testing, and receive the expected replies. You attempt to ping 157.199.23.1, which is the near side of the router that leads to the company headquarters, and you receive the following response:

Request timed out.

You then ping WORKSTATION1, which is the next client system you’re using for your testing, and receive the expected replies. You attempt to ping 157.199.23.1, which is the near side of the router that leads to the company headquarters, and you receive the following response:

Request timed out.

You then call your counterpart at company headquarters and ask him if he can ping 157.199.24.1, which is the near side of the router that leads to branch office one. He receives the expected replies.

You ask him to ping 157.199.23.1, which is the near side of the router from your location but the far side from his location. He receives the expected replies.

You ask him to ping 157.199.25.1, which is the near side of the router from his location to the RRAS server. He receives the expected replies.

You ask him to ping RRAS1, which is the name of the RRAS server on the far side of the router. He receives the expected replies.

At this point, what appears to be the most likely cause of this problem?

	A.	Routing.
	B.	Name resolution.
	C.	Default gateway configuration from company headquarters to branch one.
	D.	IP address assignment.
	E.	Not enough troubleshooting has taken place to determine the most likely cause of this problem.

Branch one has client systems running Windows XP Professional, Windows 2000 Professional, and Windows 98 and has two Windows Server 2003 systems. There is one DHCP server on this site, DHCP1. All systems on this site interconnect by hubs and connect to the company headquarters via a router.

The company headquarters has client systems running Windows XP Professional, Windows 2000 Professional, and Windows 98 and has a few Windows Server 2003 systems.

All systems at branch one can successfully connect to one another, but they cannot reach the company headquarters systems or the Internet.

You decide to test connectivity between the systems at branch one and the default gateway to the company headquarters.

You log in at WORKSTATION1, which is a Windows 2000 client, enter PING LOCALHOST, and receive the expected replies. You then decide to enter PING WORKSTATION2, which is the next client system you’re testing, and receive the expected replies. You attempt to ping 157.199.23.1, which is the near side of the router that leads to the company headquarters, and you receive the following response:

You ask him to ping 157.199.23.1, which is the near side of the router from your location but the far side from his. He receives the expected replies.

You ask him to ping 157.199.25.1, which is the near side of the router from his location to the RRAS server. He receives the expected replies.

You ask him to ping RRAS1, which is the name of the RRAS server on the far side of the router. He receives the expected replies.

You then decide to renew your IP address on WORKSTATION1 and WORKSTATION2.

How can you accomplish this task with the least amount of administrative effort?

	A.	Run Winipcfg on each client.
	B.	Run Ipconfig /new /all on each client.
	C.	Run Ipconfig /release and then Ipconfig /renew on each client.
	D.	Run Winipcfg /release and then Winipcfg /renew on each client.

You ask him to ping RRAS1, which is the name of the RRAS server on the far side of the router. He receives the expected replies.

You then decide to renew your IP address on WORKSTATION1 and WORKSTATION2.

You have checked that the renewal of IP addressing was successful by using IPCONFIG /all and have received the following information on WORKSTATION1:

Host name: WORKSTATION1

Node type: Hybrid

IP routing enabled: No

WINS proxy enabled: No

Description: D-Link DFE-550TX Fast Ethernet 10/100 adapter

Physical address: 00-50-BA-F8-B5-93

DHCP enabled: Yes

IP address: 169.254.15.6

Subnet mask: 255.255.0.0

You attempt to ping the default gateway IP address of the router that leads to the company headquarters, but you are still receiving Request timed out responses. You can ping WORKSTATION2 with success.

From the following choices, what is the most likely reason you still cannot hit the default gateway by pinging the IP address? (Please choose the single best answer.)

	A.	WINS proxy is not enabled.
	B.	IP routing is not enabled.
	C.	Ipconfig /release and Ipconfig /renew were not successful.
	D.	You are not receiving an IP address from the DHCP server.
