13.9.1. Review Questions

Question 1

How many simultaneous connections can a RAS server on a Windows NT Server support?

A.  1

B.  256

C.  254

D.  128

Question 2

What remote access protocols are supported by RAS?

A.  SLIP

B.  PPP

C.  PPTP

D.  IPX/SPX

E.  RAS Protocol

Question 3

What networking protocols are supported by RAS?

A.  NetBEUI

B.  RAS Protocol

C.  IPX

D.  AppleTalk

Question 4

You have decided to use TCP/IP as the protocol for direct dial-up access. Your company uses a DHCP server, but you want to assign static IP addresses to your remote users. How would you implement this?

A.  Exclude the range of IP addresses you wish to assign to remote clients from the scope on the DHCP server.

B.  fff.

C.  Enter the values for the IP addresses you wish to assign with RAS Server.

Question 5

Which of the following methods can you use to increase security when you allow dial-in access:

A.  Use Dial-Up Networking Monitor to log calls into your RAS Server.

B.  Set your RAS Server to call back remote clients who attempt access.

C.  Enable auditing of the guest account.

D.  Enable auditing of the remote users’ accounts.

Question 6

What should you do to allow remote users to connect to your company’s main network securely over the Internet?

A.  Configure the RAS Server and client to use PPTP.

B.  Enable encrypted logon authentication to Windows NT.

C.  Set the RAS Server so that it calls back remote users attempting to connect.

D.  You cannot configure a secure connection over the Internet.

Question 7

You suspect that remote users are logging on to your network and leaving their machines connected for long periods of idle time so that they will not be bothered to reconnect when they must use this system. You are worried that this might be consuming valuable server resources. What utility would you use to determine whether your supposition is true and how bad the problem actually is?

A.  Dial-Up Networking Monitor.

B.  Remote Access Administrator.

C.  Performance Monitor.

D.  Server Manager.

Question 8

One of your users reports that he cannot connect to the company network. Upon further questioning, you determine that his modem does dial and physically connect to the RAS Server, but when he tries to log on to Windows NT, he is unsuccessful. What two things should you check first?

A.  Whether the proper protocol is installed on the client machine.

B.  Whether the user has been granted dial-in access.

C.  Whether the user is attempting to log on with a valid user account.

D.  Whether the RAS Server is set to call back remote users.

13.9.2. Exercises

The following exercises are each based on the scenario that is presented below. Each exercise presents a problem and asks you to determine what the proper course of action should be. There are many possible solutions to each problem, so don’t worry about any particular “right” answer. The real purpose of these exercises is to get you to think about the information you have read in this chapter and how it might apply in a real-world situation.

Scenario

You are the administrator of your company’s main network. Your network consists of multiple servers and workstations configured with Windows NT 4.0. Your network is Ethernet and uses the TCP/IP protocol. One of your Windows NT Servers is configured with the RAS service and has a dial-up connection to the Internet (see Figure 13.19).

Figure 13.19.  Your company’s main network.

Your company has just acquired a smaller company, which also is networked. The new network consists of multiple servers and workstations configured with Windows NT 4.0, as well as a server and several clients configured with Novell’s NetWare. This network is token-ring–based and uses an IPX/SPX-compatible protocol (see Figure 13.20).

Figure 13.20.  The new company’s network.

Exercise 13.1

Your company wants to install a Windows NT Server on the new company’s network and configure it as a RAS Server. This server and the RAS Server on your main network will be configured so that the two networks can communicate. Sketch out a map of the proposed new network. Determine how you would configure networking protocols between the two RAS Servers.

Exercise 13.2

Your company also wants to configure the RAS Server on the main network to allow remote users to dial directly into the network. These remote users all will be using Windows 95 or Windows NT Workstation. How would you implement this? What protocols would the client machines need to be running? What steps would you take to ensure security? How would you determine the load that this is placing on your RAS Server?

Exercise 13.3

Additionally, your company has several employees that travel regularly and must be able to connect to the main network. It has been decided to do this over the Internet, if it can be done securely. Can this be done securely? How would you implement this? How would these remote users differ from the users in the previous exercise?
