Your network contains an Active Directory domain. The domain contains 10 file servers. The
file servers connect to a Fibre Channel SAN. You plan to implement 20 Hyper-V hosts in a
failover cluster.
The Hyper-V hosts will not have host bus adapters (HBAs).
You need to recommend a solution for the planned implementation that meets the following
requirements:
The virtual machines must support live migration.
The virtual hard disks (VHDs) must be stored on the file servers.
Which two technologies achieve the goal? Each correct answer presents a complete
solution.
A.
Cluster Shared Volume (CSV)
B.
An NFS share
C.
Storage pools
D.
SMB 3.0 shares
I can imagine NFS fail-over file sharing on W2012R2.
The simplest and recommended by MS is SMB 3.0 share in fail-over cluster. See here:
https://technet.microsoft.com/en-us/library/jj134187.aspx
So, the answer should be CSV and SMB 3.0.

Agreed it’s A & D

The Hyper-V host will not have HBAs -> not A -> C and D -> OK!

It is A and D. You can use iSCSI to setup CSV without HBA.

In the description are 10 File Server mentioned, no clusters. Is this the reason why the CSV is not a valid answer?

I leaned towards A&D, but after seeing C&D listed, I feel that may be the correct answer.
A) Key word is SAN. Without HBAs, it’s not an option. I know someone mentioned you can use iSCSI and would like to see an example of this.
B) Clearly not correct
C) Pretty basic and meets requirements
D) Recommended by MS and supports requirements.

Okay People, I spent an extraordinary amount of time on this, and now you won’t have to 🙂
C + D = Correct!
Windows Server 2012 SOFS (Scale-Out File Server) dramatically simplifies managing the spiderweb of Hyper-V server-to-storage connections. When combined with the performance and scalability enhancements now in SMB 3.0, it takes much of the interconnecting out of your hands.
With SOFS in place, accessing a Hyper-V VM requires little more than a UNC path: \\server\share\folder\vm.vhdx (This means there is no need for HBA.) SMB 3.0 automatically handles everything else—redundancy, load balancing, failover and the gamut of fault tolerance networking goals. Even the SOFS cluster itself is active-active in nature, which means no server purchase goes unused in driving the storage needs of your Hyper-V VMs.
Also:The storage requirement of a SOFS is cluster supported storage. That includes:
SAS SAN
iSCSI SAN
FIBRE CHANNEL SAN!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
FCoE SAN
PCI RAID (like the Dell VRTX)
… and SAS attached shared JBOD + Storage Spaces

Not A:
If you are using a Fibre Channel storage area network (SAN), each host that will access the storage array must have a host bus adapter (HBA) installed. Additionally, make sure that the v hosts are zoned accordingly so that they can access the storage array.
Not B:

Storage Spaces with a storage pool in a cluster only supports SAS disks.
What’s wrong with adding disks to the fileservers using FC and create a SMB 3.0 share.
The HV servers can connect to it and stor the VHD’s in the remote share.
A,D looks good

A & D. Why?
You guys are not talking about live migration.
You must have a CSV to do live migration. (https://technet.microsoft.com/en-us/library/hh831435.aspx)
Must use SMB 3.0 to store the VHD’s on the file servers

Matt, You only need a CSV for live migration in a Cluster.

Which now that I look again “You plan to implement 20 Hyper-V hosts in a
failover cluster.”
So CSV is definitely needed.
The link does list the requirements for live migration.

I think that everything posted made a great deal of sense. But, what about this? suppose you were to write a killer title? I am not suggesting your content isn’t solid., however what if you added a headline to maybe grab a person’s attention? I mean %BLOG_TITLE% is a little vanilla. You could look at Yahoo’s front page and see how they create article titles to get viewers interested. You might try adding a video or a related picture or two to get readers interested about everything’ve written. In my opinion, it would make your website a little bit more interesting.|
