| Three parter today.

A)Striped set w/Parity (Raid 5)
B)Mirrored Set (Raid 1)
And part two of the question:
In Windows 2000 Server, a Mirrored Set is required to be a:
A)Basic Disk
B)Dynamic Disk
And part three:
What is the minimum number of disk required for a Raid 5 set?
A)4
B)8
C)6
D)3
Good luck! See you tomorrow! | |

| Time for the answer.
You have a server that is running out of disk space. You want to increase
the disk space with the least amount of expense, and it must be fault
tolerant. Which is your best choice?
B)Mirrored Set (Raid 1)
A fault-tolerant volume that duplicates data on two physical disk. A mirrored volume provides data redundancy by using two identical volumes, which are called mirrors, to duplicate the information contained on the
volume. A mirror is always located on a different disk. You can create volumes only on dynamic disk on computers running Windows Server 2000 or Windows Server 2003 families of operating systems. You cannot extend
mirrored volumes.
Also, a Mirrored Set has a lower cost because it requires only two disks; a RAID-5 volume requires more disks. Requires less system memory. Provides better overall performance. Does not degrade performance during a failure except when high-volume read operations are performed. If a single write error occurs, however, redundancy is lost.
And part two of the question:
In Windows 2000 Server, a Mirrored Set is required to be a:
B)Dynamic Disk
All members of a RAID 1 volume set must be on a dynamic disk.
And part three:
What is the minimum number of disk required for a Raid 5 set?
D)3
You need a minimum of three hard disk to set up fault tolerance.
I will try to post another later today. | |

| I do not believe B on the first question can be correct, as you are not increasing the disk space of the server, you are merely replicating the data onto another drive.
Edit note: darn typos

| I disagree with the answer to the first part as well.
Mirroring only replicates the data at a cost of 50% of overhead.
RAID5 on the other hand starts out with overhead of 33% (3 drives) and decreases as more drives are added.
Regardless, the question says the goal is to increase disk space...mirroring certainly does not do this.
The least cost, in terms of storage space, is accomplished with RAID5. Concidering how many physical drives need to be added implies an assumed monetary cost.
Correct me if these thoughts are flawed. | |
| ghaouf 2003-06-27, 3:24 pm |
| i agree that part 1 should be A
because RAID 1 does not increase the size of the disk, it just makes an exact copy of the first drive on another disk. | |
|
| I agree with isles1,
A mirrored set (RAID 1) does not increase your disk space at all. The answer to the first part can not be RAID 1.
I have (2)18.2GB disks, I want to increase disk space, I setup a mirror, I only have 18.2GB worth of space I can use. There is no increase in space available for usage. If anything, you've reduced your available space at the cost of fault tolerance. | |

Wish I could get away with an 18.2GB HD on any one of my servers! (Or even 2 for that matter! ) | |

| This would be more of a Microsoft question:
You are the systems admininstrator servicing a 120 user domain. You currently have a file server running Windows 2000 Server Advanced Server with a 4.3GB SCSI hard drive for the system and boot partitions and an 18.2GB SCSI hard drive used to store user data.
Your primary objective is to increase the disk space on the file server. You have a secondary objectives of implimenting it at the least amount of expense and the setup must be fault tolerant.
As a solution, you have elected to use RAID 1.
A. This meets all of the objectives.
B. This meets the primary objective but none of the secondary objectives.
C. This meets the primary objective and one of the secondary objectives.
D. This meets one secondary objective.
E. This meets both secondary objectives.
F. This does not meet any objective.
Cheers,

Yeah, that's an M$ question alright. Just meant I was getting as ambigious as M$. ( I really can't stand the way M$ words some of their questions.) | |

Okay, I give up. Poorly worded question! I will try to be more accurate from now on. (At least I got people to discuss this one.) But if you installed two larger drives, and mirrored them, you would be saving $$ and have fault tolerance, (buying 2 drives instead of 3 or more would save money). Right? | |
| karlisi 2003-06-28, 3:09 am |
| mrfixit, first part of your question was - You have a server that is running out of disk space. You want to increase the disk space with the least amount of expense, and it must be fault tolerant
Mirroring does nothing for increasing disk space (this was first part), only for fault tolerance (and this was second part). Ansver B is only partly right and, in Microsoft exam (and in real life too), it means wrong. Sorry...
Next time please read your question like another person (or show it to someone) before publishing. It helps, believe me  | |

I want to thank MrFixIt for posting these questions at all. These are questions that give people something to think about at a bargain price.

Not if the store is doing a 3 for the price of 2 deal

It's good to be appreciated!
The whole idea of the QoD is to get you folks thinking. And I will word my questions more carefully from now on. | |

As stated, a mirrored set only requires two disk, thus saving $$$. If you installed a Raid 5, which requires a minimum of three disk, you are not saving $$$. The question does not state that you are just adding a disk drive. (You could be installing two new larger HD's.)Guess I should be more clear on these questions, but kind of got into the M$ mind set. (Ambiguious)
as i was the only one who got it right, do i get a prize? | |
