Rooslan is a consultant who has been approached by a medium-sized organization forhis advice on the best way to optimize disk performance for three newly purchasedWindows Server 2003 systems. There are three different systems in question, all withidentical hardware. Each server has six 120 GB SCSI hard disk drives and no hardwareRAID controller. Rooslan has been presented with the following specifications from theteams that will be using each Windows Server 2003 System.The team that will use the first server has one goal. The team would like a second largevolume of approximately 600 GB that will contain all the data. The first volume of 120 GBshould contain the operating system files and the program files. Speed and fault toleranceare not important to this team.The team that will use the second server has three goals. The first goal is that the primaryvolume be 120 GB in size, fault-tolerant, and host the operating system and programfiles. The second goal is that the secondary volume be 120 GB in size, faulttolerant,and store program data. The third goal is that the tertiary volume be 240 GBin size and provide the fastest possible read/write speeds.The team that will use the third server has two goals. The first goal is that the primaryvolume must be approximately 120 GB in size, host the operating system and the programfiles, and be fault-tolerant. The second goal is that the secondary volume must beapproximately 480 GB in size and have the best read/write performance possible.Rooslan installs Windows Server 2003 on the first teams server, using a full disk partitionon which he installs the operating system and the program files. Once he is inWindows Server 2003 he converts the five other disks to dynamic and spans a singlevolume across all these disks.On the second teams server, Rooslan installs Windows Server 2003 using the entire 120 GBavailable on the disk. When he has Windows Server 2003 configured, he mirrors this120 GB disk onto the second 120 GB disk. He then installs the relevant program filesonto this volume. He then creates two more mirrored pairs with the third and fourthand the fifth and sixth 120 GB disks.On the third teams server, Rooslan installs Windows using the entire 120 GB availableon the first disk. When he has Windows configured he mirrors the 120 GB disk ontothe second 120 GB disk. He then installs the relevant program files onto this volume.Rooslan then creates a RAID-5 volume using the final four 120 GB disks.Which of the following statements accurately summarizes the number of team goalsthat Rooslan accomplished?
A. Rooslan achieved the first team’s goal, as well as all goals of the second team and all goals of the third team B. Rooslan achieved the first team’s goal, two of the second team’s goals, and all the third team’s goals. C. Rooslan achieved the first team’s goal, all the second team’s goals, and one of the third team’s goals D. Rooslan did not achieve the first team’s goal, achieved all the second team’s goals, and achieved one of the third team’s goals E. Rooslan achieved the first team’s goal, achieved two of the second team’s goals, and achieved one of the third team’s goals.
Rooslan achieved the first team’s goal, achieved two of the second team’s goals, and achieved one of the third team’s goals.-f. correct: rooslan achieved all the goals of the first team. for the second team, heachieved the first and second goals. in choosing to mirror, rather than stripe, thethird volume, he did not create a volume of 240 gb with the fastest read/writespeed. the volume would have been 120 gb and would not have performed significantlybetter than a simple volume. rooslan achieved one goal of the thirdteam. he achieved the first goal, but by using raid-5 instead of striping, he failedto achieve the second. the second volume would have been 360 gb rather than480 gb as specified, the equivalent of one drive lost in storing parity information.
