• Only Partition C can be marked as active. Partition D is not a primary partition, and thus cannot be marked as active.

b. What are the file systems in use on this Windows NT Workstation?

• FAT and NTFS

• 123 MB on the FAT partition and 690 MB on the NTFS partition.

d. What is the volume label name for each partition?

e. Is Disk 0 a SCSI or an IDE hard-disk?

• This information cannot be determined with Disk Administrator.

19. What is the maximum number of primary partitions a single hard-disk can contain?

• A maximum of four

20. What is the maximum number of extended partitions a single hard-disk can contain?

• One

21. Volume sets and Stripe sets are initially created from:

1. Free space only.
2. NTFS partitions only.
3. FAT partitions only.
4. Either a boot or system partition.
5. One must convert a FAT partition to NTFS then create a volume or stripe set.

• Free space only.

22. Which of the following cannot be performed on a Windows NT Workstation:

1. Extending a NTFS volume set by combining an existing volume set with a free space.
2. Extending a NTFS stripe set partition by combining an existing stripe set with a free space.
3. Create a volume set by combining two or more free areas on a single hard-disk.
4. Create a stripe set by combining two or more free areas on a single hard-disk.
5. Create a stripe set by combining free areas on two drives, one drive being IDE, and the other SCSI.

• Extending a NTFS stripe set partition by combining an existing stripe set with a free space.
• Create a stripe set by combining two or more free areas on a single hard-disk.

23. User Racer-X has 3 hard-disks on his Windows NT Workstation. The free areas on each of the three disks are 150 MB, 200 MB, and 75 MB in size respectively. For each configuration below, what can Racer-X do?

a. Racer-X wants to create a volume set. What is the largest size volume set he can create?

• 425 MB

b. Racer-X wants to create a stripe set. What is the largest stripe he can create using any combination of the drives?

• 300 MB

24. User Trixi has a Windows NT Workstation identical to Racer-X's. She also has 150, 200, and 75 megabytes of free space on her three hard-disks.

a. What is the smallest stripe set she can create using any combination of the drives, but using all the free space from any drive she chooses to have in her combination?

• 150 MB

b. What is the largest stripe set she can create using all the drives?
