B. %Usage Peak

C. %Processor Utilization

D. %Processor Queue length

8. There is a client/server application on a Netware server which you would like to access using Windows NT Workstation. What will you need to enable connectivity?

9. What connectivity feature of Windows NT enables secure access to your network over a public network?

A. SLIP

B. PPP

C. PPTP

D. NetBIOS Scope ID

10. How many simultaneous inbound connections are supported by Windows NT Server?

A. 1

B. 32

C. 256

D. There is no limit to the number of connections.

11. What service must be running in order to have Autodial functionality?

B. Remote Access Service

C. Remote Access Autodial Manager

D. Dial-Up Networking Service

12. What does the Multilink protocol allow you to do with RAS?

A. Use ISDN to make a connection.

B. Use multiple protocols when making a RAS connection.

C. Allow more than one client to use the RAS server at once.

D. Allow one client to use multiple phone lines

13. What needs to be installed to configure AppleTalk?

A. TCP/IP

B. LocalTalk

C. Services for Macintosh

D. NT Client for Macintosh

14. You want to be able to monitor the performance of physical disk counters. What step do you take first?

A. Run the Diskperf utility with the -on option.

B. Run the Diskperf utility with the -y option.

C. Enable physical disk counters under Administrative Tools-->Disk Administrator.

D. Physical disk counters are enabled by default.

1. (C)

The command is diskperf -y

2. (A)

An object represents a mechanism for identifying system resources such as processor, memory, etc.

3. (D)

Up to 32 physical disks can be part of a RAID 5 array.

4. (C)

By placing the emphasis on the background tasks, NT reserves more processor time for programs that are running in the background, such as database and application servers.

5. (D)

A low number of available bytes and increasing disk time usually indicates that the swap file is being accessed frequently. This problem is usually caused by a lack of physical RAM in the server.

6. (A)

Disk Mirroring is the only scheme listed that will allow a system partition.

The %Processor Queue Length refers to how many jobs are lined up waiting for processor time. The %Processor Utilization tells you how much the processor itself is being used, and the %Queue Length tells you the number of jobs.

8. (B)

If you are connecting to a client/server application, all that is required is NWLink.

9. (C)

PPTP enables secure tunnels to be established over a public network.

10. (C)

Windows NT can support 256 inbound RAS connections.

11. (C)

The Remote Access Autodial Manager must be running in order for Autodial to be available.

12. (D)

Multilink enables multiple phone lines and modems to be used. This provides more bandwidth for the user.

13. (C)

Services for Macintosh must be installed.

14. (B)

Because monitoring disk performance has a slight degradation on server performance, it is disabled by default. You need to run the DISKPERF -y command at the command prompt and restart the server in order for it to take effect.
