You have a server named Server1. Server1 runs Windows Server 2012 and has the File and Storage Services
server role installed.
You attach four 500-GB disks to Server1.
You need to configure the storage to meet the following requirements:
Storage for an Application named Application1 must be provided. Application1 requires 20 GB and will require a
maximum of 800 GB in three years. Storage for an Application named Application2 must be provided.
Application2 requires 20 GB and will require a maximum of 900 GB in three years. The solution must provide
the ability to dynamically add storage without requiring configuration changes to the Applications.
The storage must be available if a single disk fails.
Which two actions should you perform? (Each correctanswer presents part of the solution.
Choose two.)
A.
From File and Storage Services, create virtual disks by using fixed provisioning.
B.
From File and Storage Services, create a storage pool that uses all four disks.
C.
From Disk Management, create two new mirror volumes that use two disks each.
D.
From Disk Management, create a new RAID-5 volume that uses all four disks.
E.
From File and Storage Services, create virtual disks by using thin provisioning.
Explanation:
A: 2 VHD’s set to fixed size of 800 & 900GB
B: Allows Fault Tolerance
C: No Fault Tolerance MAX when mirroring 2 500GB drives D: 1500GB MAX App’s require 1700GB MAX
E: No Fault Tolerance

That is imposible beacuse the solution must provided that the space continue run if a one disk fail.

I see some other dump mention B and E

The correct answer is B and E. it can’t be A, because a fixed disk can’t get expanding.

You can add physical disks to storage pool without reconfiguring the applications, so you don’t need to have thin provisioning, the storage pool do it itself. Dont you think?

no you need thin provisioning bc u need to have redundancy. 4×500 = 2000.
800 + 900 = 1700. If 1 disk fails you have nothing left.
With thin provisioning the disk size is sufficient until it reaches 1500. You should add another disk by then.

But the question asks, “The storage must be available if a single disk fails”..

One disk is reserved for fault tolerance. That leaves three 500GB disks for a total of 1500GB. Have one fixed 800GB and one thin provisioned 900GB. When the 900 GB reaches 700GB, physically, add more disks to the storage pool. Therefore, the answer is B and E. I don’t like E’s answer: it implies both disks should be thin provisioned.

After seeing this video https://www.youtube.com/watch?v=oF1VoIftDMs it is BE

If the answer is AB then where is the redundancy? If we create fixed storage volumes then we must allocate 1700gb. The maximum storage we can provide with redundancy is 1500gb. The answer provided does not offer redundancy.
If we create a storage pool from all 4 disks using parity storage layout we have 1500gb available. We can then create thin provisioned volumes for each application.

Why not RAID 5 instead storage pool??

B and E. 4 Disks in Raid-5 would give you 1.5TB of storage. The apps will eventually require 800GB + 900GB = 1.7TB, so thin provisioning is needed.

You all count with RAID 5, but that´s not the question. There´s no RAID 5 in storage space. You can only select Parity with four sidks to provide fault tolerance. This gives you the sam resiliency, but with big MS mojo 🙂
And if like someone mentioned you use two mirrored drives… youre stuck with only 500 GB each… as it´s still mirror.

beanxyz is correct.

No he isn’t, there wouldn’t be enough disk space for that.

JR is right. If you use Mirrored, you would have 2 1TB drives which would not support the 1.7TB that they will need down the road. It’s B & E.

it is possible “B. From File and Storage Services, create a storage pool that uses all four disks.” then “E. From File and Storage Services, create virtual disks by using thin provisioning.” with selecting parity under “Storage Layout”

B.create a storage pool (with Parity Layout)
because we need:
1. “the ability to dynamically add storage without requiring configuration
changes to the applications”
2. “The storage must be available if a single disk fails”
E.thin provisioning.
because we need:
1. “will require a maximum of 800 GB in three years”
2. “will require a maximum of 900 GB in three years”

B and E (sort of)…
B definitely as a storage pool provides the option of fault tolerance through mirrored or parity disks
E as creating a storage pool with parity to provide the fault tolerance will not allow enough storage for the apps to grow into (1.5TB of storage available when the apps will eventually require 1.7TB), so thin provisioning is needed.

B and E. Otherwise you don’t have enough space for fault tolorance (or expansion in future)
