Answer Set #12

Featuring the challenges faced by FBI Agents Fox Mulder and Dana Scully

Problem Set questions appear in this color, and the Answers appear in this color.

1. Just before finishing up their work on the Peacock case in Home, Pennsylvania and heading back to D.C., Agents Mulder and Scully (each using their own laptop) write separate reports and prepare to connect to a NT-based server at FBI Headquarters via RAS to send the finalized reports. From her hotel room, Scully makes a RAS connection to the NT server and begins uploading her set of files -- many megabytes, of course. At the same time, Mulder attempts to connect to the same RAS server and cannot even connect. What might be the potential problems here?

1. * The RAS server might actually be a NT Workstation
2. * The RAS server is not set up with a NTFS partition
3. * Only Scully has been granted dialin permissions on the RAS server
4. * Mulder is not a member of the Administrators Group, however Scully is

• * The RAS server might actually be a NT Workstation
• * Only Scully has been granted dialin permissions on the RAS server 

2. If a NT Server at FBI Headquarters is a Windows NT 3.51 Server, up to how many simultaneous connections can be handled via RAS?

• * 256 connections

3. There are two protocols through which RAS connections can be made. One was designed to be an enhancement to the original protocol specification. What are those two protocols?

• * SLIP
• * PPP (the enhancement to SLIP)

4. If Agent Mulder needs to connect to a UNIX-based SLIP server in Washington D.C., what networking protocol needs to be installed and configured on his RAS client?

• * TCP/IP

5. On his laptop, Agent Mulder has many games and pictures (we'll assume from the Internet). He hasn't installed RAS on his NT Workstation, but he needs to in order to get his work done. When he tries to install RAS, he is informed that there is not enough disk space for the RAS software. What is the minimum free disk space he needs to install RAS?

• * 2 MB

6. Meanwhile, Scully has made it back to FBI Headquarters and configures her NT server for RAS access. If the NetBIOS Gateway is disabled on the server, which of the following is true for Agent Mulder if he attempts to connect over RAS from his laptop:

• * He will see the shared directories on the NT server
• * He will see the shared printers on the NT server
• * He will see all the computers on the network and their shared directories
• * He will see all the computers on the network and their shared printers

• * He will see the shared directories on the NT server
• * He will see the shared printers on the NT server

7. The FBI local-area network uses the TCP/IP protocol, and Agent Mulder (again, he's still out in the field using his laptop to connect to the FBI office via RAS) only has the NetBEUI protocol configured for RAS. Assuming he has access to the network through the NetBIOS Gateway, will his computer be able to see the TCP/IP network even though he only is using NetBEUI for a networking protocol?

• * Yes, because the NetBIOS Gateway receives the NetBEUI requests from the RAS clients and passes them to the NetBIOS compatible protocols (in this case TCP/IP) installed on the RAS server.

8. If Scully wants to grant users dialin access to the NT RAS server, which interface allows her to grant the necessary dialin permissions?

• * User Manager
• * User Manager for Domains
• * Remote Access tool
• * Remote Access Admin tool
• * DHCP Manager

• * Remote Access Admin tool

9. Which Callback Security option below is the most secure? What is one potential drawback of the most secure method?

• * Set By Caller (Call the user back at a user-specified number)
• * Preset To (Call the user back at a preset number)
• * No Call Back (Not call the user back)

• * Preset To. Using this method, a phone number is hard-coded into the RAS server by an administrator. This number cannot be changed, except from the RAS server, and thus if the RAS client has the need to use different phone numbers (for instance, while out on the road or during traveling), this option would not work.

10. In which directory are RAS log files maintained?

• * <winnt_root>\SYSTEM
• * <winnt_root>\SYSTEM32
• * <winnt_root>\SYSTEM32\RAS
• * <winnt_root>\SYSTEM32\RAS\LOGS

• * <winnt_root>\SYSTEM32\RAS
