Answers to Exam Prep Questions
- Answer C is correct. RAID 1 (disk mirroring) needs two disks to be implemented. Before you can enable RAID 1 using Windows Server 2008, you need to convert basic disks to dynamic disks, which converts the partitions into volumes. Answers A and B are incorrect because write catching improves disk performance but does not help implement RAID 1. Answer D is incorrect because to implement RAID 1 using Windows Server 2008, you must use dynamic disks.
- Answer B is correct. RAID 1, disk mirroring, uses two disks to provide fault tolerance. In RAID 1, whatever is written to one disk is written to the other. Answer A is incorrect because RAID 0, disk striping, does enhance performance, but does not provide fault tolerance. Answers C and D are incorrect because RAID 5 (disk striping with parity) needs three disks to be implemented.
- Answers A, C, and D are correct. Windows Server 2003 supports disk striping (RAID 0), disk striping with parity (RAID 5), and disk mirroring (RAID 1). Answer B is incorrect because Windows Server 2008 does not natively support hammering code error-correcting code (ECC) disk configurations (RAID 2). Answer E is incorrect because Windows Server 2008 does not natively support striped volumes that are part of a mirrored set (RAID 0+1). Answer F is incorrect because Windows Server 2008 does not natively support mirrored volumes that are part of a striped array set (RAID 10).
- Answers A and C are correct. You can install a fresh copy of Windows Server 2008 onto a basic partition and onto a dynamic volume if the volume was originally a basic partition that was upgraded to dynamic because Windows Server 2008 can be installed only on a disk that contains a partition table. Answer B is incorrect because a dynamic volume that was created from unallocated space does not contain a partition table. Answer D is incorrect because Windows Server 2008 Setup does not support installation onto removable media such as USB disks or IEEE 1394 (FireWire) disks. Answer E is incorrect because you can install only one operating system per dynamic disk.
- Answer D is correct. Of these four options, only striped volume with parity is fault tolerant. If one hard drive fails, the data will still be accessible. Answers A, B, and C are incorrect because although striped volumes do provide better performance, they do not provide fault tolerance. If one disk fails, you loose all data.
- Answer E is correct. To use RAID provided by Windows Server 2008, you must use dynamic disks. To provide fault tolerance, you create a mirrored set using disk 0 and 1. Answers A, B, and C are incorrect because a basic disk cannot be used for mirror or RAID 5 disks. Answer D is incorrect because the striped set is not fault tolerant.
- Answer B is correct. You can create up to four primary partitions on a basic disk without an extended partition. Answer A is incorrect because you are limited to three primary partitions only if there is an extended partition on the disk. Answer C is incorrect because you can have more than one primary partition on a basic disk. Answer D is incorrect because you are limited to a maximum of four primary partitions on a basic MBR disk; a basic GPT disk can host up to 128 partitions.
- Answers D and E are correct. To convert dynamic disks back to basic disks, you must remove all volumes on the disk, which means that all data must be removed as well. IEEE 1394 (or FireWire) disks cannot be converted to dynamic; therefore, they can only be basic disks. Answer A is incorrect because basic disks are supported under Windows Server 2008. Answer B is incorrect because basic disk sets that were created under previous versions of Microsoft server products are not mounted by the operating system; you must use the ftonline.exe tool on the setup CD-ROM. Answer C is incorrect because basic disks (and dynamic disks) can be formatted as FAT, FAT32, or NTFS.
- Answer B is correct. The command to use to convert a basic disk to a dynamic disk is diskpart convert dynamic. Answer A is incorrect because the command is diskpart convert dynamic. Answers C and D are incorrect because the format and convert commands cannot be used to convert basic to dynamic disks.
- Answer B is correct. The iscsicli AddPersistentDevices command makes an iSCSI device persistent so that it connects every time the system boots. Answer A is incorrect because iscsicli AddTarget only creates a connection to a volume or device. If you reboot your system, it does not automatically connect. Answers C and D are incorrect because the iscsicli RemovePersistentDevices command prevents the reconnection to a specified volume, and the iscsicli ClearPersistentDevices command removes all volumes and devices from the list of persistent devices.
- Answer D is correct. The iscsicli RemovePersistentDevices command prevents reconnection to a specified volume. Answer A is incorrect because iscsicli AddTarget only creates a connection to a volume or device. If you reboot your system, it does not automatically connect. Answer B is incorrect because the iscsicli AddPersistentDevices command makes an iSCSI device persistent so that it connects every time the system boots. Answer C is incorrect because the iscsicli RemovePersistentDevices command prevents the reconnection to a specified volume, not all volumes.
- Answer C is correct. The diskpart command is a powerful disk management tool that can convert an MBR disk to a GUID partition table disk. Answer A is incorrect because fdisk is a partitioning tool used in older operating systems. Answer B is incorrect because the format command is used to format a disk, which would define FAT32 or NTFS. Answer D is incorrect because the convert command could be used to convert a FAT32 volume to a NTFS volume.
- Answer D is correct. The default port for iSCSI is 3260. Answer A is incorrect because TCP port 389 is used by Lightweight Directory Access Protocol (LDAP). Answer B is incorrect because TCP port 443 is used by SSL. Answer C is incorrect because TCP port 1433 is used by SQL servers.
- Answer C is correct. The address is an example of the iSCSI Qualified Name, which is the most commonly used iSCSI address. Answer A is incorrect because the MAC addresses used to identify network cards are 48-bits/12 hexadecimal numbers. Answer B is incorrect because an IPv4 address is a 32-bit address consisting of four 8-bit octets, each octet ranging from 0-255. Answer D is incorrect because the Extended Unique Identifier is another addressing scheme used by iSCSI, which is provided by the IEEE Registration authority in accordance with EUI-64 standard (EUI is short for extended unique identifier).
