1. You have a new Windows 7 computer with multiple hard drives. You want to implement RAID1 on the computer. What do you need to do first?

❍ A. Enable write caching on the first disk ❍ B. Enable write caching on the second disk ❍ C. Convert the basic disk to dynamic disks ❍ D. Convert the dynamic disk to basic disks

2. You have a computer running Windows 7. Your system has a large hard drive with one volume that holds the Windows 7 volume. Out of 500 GB, you realize that you are only using approximately 100 GB. You decide you want to create a new volume on disk 0. What should you do?

❍ A. Compress volume C ❍ B. Create a virtual hard disk (VHD) ❍ C. Shrink volume C ❍ D. Configure a disk quota for volume C

3. What is the maximum number of volumes you can add to a striped volume?

❍ A. 2 ❍ B. 4 ❍ C. 8 ❍ D. 16 ❍ E. 32

Answers

1. C is correct. RAID1 (disk mirroring) needs two disks to implement. Before you can enable RAID1 using Windows 7, you need to convert basic disks to dynamic disks, which converts the partitions into volumes. Answers A and B are incorrect because write caching only improves disk perform- ance and does not help implement RAID1. Answer D is incorrect because to implement RAID1 using Windows 7, you must use dynamic disks.

2. C is correct. To make room for the new volume, you can shrink the system drive assuming the disk drive is set to dynamic. Answer A is incorrect because compressing volume C only gives you more disk space on the C drive but does not shrink the volume itself. Answer B is incorrect because

a virtual hard disk can be attached to a system, but it does not add a volume to the 500 GB drive. Answer D is incorrect because disk quotas help you manage the disk to make sure users do not use too much disk space.

3. E is correct. A striped volume can contain up to 32 volumes. Therefore, the other answers are incorrect.

You can create primary partitions, extended partitions, and logical drives only on basic disks. Partitions and logical drives can reside only on basic disks. You can create up to four primary partitions on a basic disk or up to three primary partitions and one extended partition. You can use the free space in an extend-

ed partition to create multiple logical drives. You must be a member of the local Administrators group or the backup operators group, or else the proper authority must be delegated to you (if you are working within an Active Directory environment) to create, modify, or delete basic volumes.

You must first create an extended partition before you can create a new logical drive, if no extended partition exists already. If you choose to delete a partition, all data on the deleted partition or logical drive is lost. You cannot recover deleted partitions or logical drives. You cannot delete the system partition, boot partition, or any partition that contains an active paging file. The operat- ing system uses one or more paging files on disk as virtual memory that can

be swapped into and out of the computer’s physical random access memory (RAM) as the system’s load and volume of data dictate.
