Your network contains an Active Directory domain named contoso.com. The domain contains two
member servers named Server1 and Server2. All servers run Windows Server 2012 R2.
Server1 and Server2 have the Failover Clustering feature installed. The servers are configured as
nodes in a failover cluster named Cluster1. Cluster1 has access to four physical disks. The disks are
configured as shown in the following table.
You need to ensure that all of the disks can be added to a Cluster Shared Volume (CSV).
Which two actions should you perform? (Each correct answer presents part of the solution. Choose
two.)
A.
Enable BitLocker on Disk4
B.
Disable BitLocker on Disk1
C.
Format Disk2 to use NTFS
D.
Format Disk3 to use NTFS
If you need to format the disk with ReFS on it, why does Windows 2012 R2 support the ReFS feature for CSV? See https://technet.microsoft.com/en-us/library/dn265972.aspx ?
Is the question still valid or am I missing something?
2012 R2 supports BitLocker. But from what I see out there it says BitLocker is supported on volumes. https://technet.microsoft.com/en-us/library/dn383585.aspx
My question is, would you not have to disable BitLocker on the disk prior to adding it to the CSV. then if you wish to use BitLocker, you would then BitLocker the volume, not individual disks,
2012 R2 supports refs in CSV. Answer is outdated
Windows Server 2012 R2, CSV functionality has been enhanced to include support for the following features:
Resilient File System (ReFS)
Deduplication
Parity storage spaces
Tiered storage spaces
Storage Spaces write-back caching
As taken from microsoft site https://technet.microsoft.com/en-us/library/dn265972.aspx
Bitlocker is also supported too but wouldnt all nodes in the cluster have to have bitlocker enabled?
C for sure & B. disks have to be fully decrypted first. Once CSV is created, then put the bitlocker on to encrypted the disk.

Answers are B & C.

“To use CSV, your storage and disks must meet the following requirements:
File system format. In Windows Server 2012 R2, a disk or storage space for a CSV volume must be a basic disk that is partitioned with NTFS or ReFS. In Windows Server 2012, a disk or storage space for a CSV volume must be a basic disk that is partitioned with NTFS.
A CSV has the following additional requirements:
In Windows Server 2012 R2, you cannot use a disk for a CSV that is formatted with FAT or FAT32.
In Windows Server 2012, you cannot use a disk for a CSV that is formatted with FAT, FAT32, or ReFS.
If you want to use a storage space for a CSV, you can configure a simple space or a mirror space. In Windows Server 2012 R2, you can also configure a parity space. (In Windows Server 2012, CSV does not support parity spaces.)
A CSV cannot be used as a quorum witness disk. For more information about the cluster quorum, see Configure and Manage the Quorum in a Windows Server 2012 Failover Cluster.
After you add a disk as a CSV, it is designated in the CSVFS format (for CSV File System). This allows the cluster and other software to differentiate the CSV storage from other NTFS or ReFS storage. Generally, CSVFS supports the same functionality as NTFS or ReFS. However, certain features are not supported. For example, in Windows Server 2012 R2, you cannot enable compression on CSV. In Windows Server 2012, you cannot enable data deduplication or compression on CSV.”
Agreed. Concerning choice B, check this:
https://blogs.msdn.microsoft.com/clustering/2012/07/20/how-to-configure-bitlocker-encrypted-clustered-disks-in-windows-server-2012/
The CSV has to be created prior enabling bitlocker, so disabling bitlocker on disk1 is mandatory.
Here are a number of the websites we advise for our visitors.
usually posts some extremely interesting stuff like this. If you are new to this site
although websites we backlink to below are considerably not connected to ours, we feel they are really really worth a go by, so have a look
Windows server 2012 R2 support REFS,
https://technet.microsoft.com/en-us/library/jj612868.aspx therefore it should be Format Disk2 to use NTFS and
Disable BitLocker on Disk1
https://technet.microsoft.com/en-ca/video/microsoft-virtual-academy-bitlocker-on-cluster-share-volumes.aspx
you don’t need to disable bitlocker on drive1 , you can add drive with enabled bitlocker to csv, in my opinion correct answers: C,D

Answers
-Enable BitLocker on Disk4
-Format disk2 to use NTFS
-Enable BitLocker on Disk4
quoting from
https://technet.microsoft.com/en-us/library/dn383585(v=ws.11).aspx
“Windows Server 2012 has expanded the CSV architecture, now known as CSV2.0, to enable support for BitLocker. When using BitLocker with volumes designated for a cluster, the volume will need to turn on BitLocker before its addition to the storage pool within cluster or put the resource into maintenance mode before BitLocker operations will complete.”
(…)
“BitLocker encryption is available for disks before or after addition to a cluster storage pool. The advantage of encrypting volumes prior to adding them to a cluster is that the disk resource does not require suspending the resource to complete the operation.”
In summary. BitLocker is available either before or after the addition to the cluster storage pool but adding the BitLocker BEFORE, is recommended.
-Format disk2 to use NTFS
quoting from
https://technet.microsoft.com/en-us/library/jj612868.aspx
(…)
In Windows Server 2012 R2, you cannot use a disk for a CSV that is formatted with FAT or FAT32.
In Windows Server 2012, you cannot use a disk for a CSV that is formatted with FAT, FAT32, or ReFS.
(…)
also on the same link referring something regarding the first choice.
(…)
Support was added (…) for integration with general storage features such as BitLocker-encrypted volumes and Storage Spaces.
so IMHO answers A,C
In my opinion it is: A & D:
Windows Server 2012 (R2) does not support FAT or FAT32 for CSV >> A
And Windows Server 2012 (R2) does support BitLocker on VOLUMES, but not for DISKS. >>D
So you can Enable BitLocker on a volume, before or after you add it to a CSV.
