| The biggest advantage of Cluster Shared Volumes (CSVs) is? |
|
Definition
| They can be shared by multiple cluster nodes at the same time. This is usually not possible with shared storage-even volumes on the same LUN. |
|
|
Term
| What is the only disadvantage to a "Quick Migration"? |
|
Definition
| The VM must be taken offline. However, this is the fastest method of migrating to another host. |
|
|
Term
| How can Clustered Shared Volumes (CSVs) achieve simultaneous shared access? |
|
Definition
By separating the data from different nodes into virtual hard disk (VHD) files. Each shared volume has multiple VHDs used as the storage for a particular HA application(Role)The CSVs are then mapped to a common namespace on all nodes. CSVs appear as subfolders in the "ClusterStorage" folder on the system drive. eg) C:\ClusterStorage\Volume3
CSVs are NTFS but appear as CSVFS or Cluster Shared Volume File System |

Term
| Scale-Out File servers (SoFS) are designed for what use? |
|
Definition
| Storage for applications like SQL database applications that store data on file shares and keep files open for extended periods. SoFS are not designed for everyday user storage. |
|
|
Term
| One major incompatibility will cause a live migration to fail. What is it and how should you successfully migrate the vm? |
|
Definition
| Source and destination processors are from different manufacturers. To migrate, export the source VM and import it on the destination host. Live and Quick migrations are not possible. |

Term
| Cluster Shared Volumes (CSVs) are used in what type of clusters? |
|
Definition
|
|
Term
| Scale-Out File Servers use what type of storage? |
|
Definition
| Cluster Shared Volumes (CSVs) only |
|
|
Term
| This type of storage is a new type of storage used only in failover clusters... |
|
Definition
| Cluster Shared Volumes (CSV) |
|
|
Term
| Scale-Out File Servers are similar to SAN storage in what way? |
|
Definition
| Client requests are distributed among all cluster nodes creating a single logical storage unit composed of storage from multiple nodes. |
|
|
Term
| Server 2012 Cluster Shared Volumes (CSVs) can be used in what two applications? |
|
Definition
Scale-out File Server
Live Migration (recommended but not required-when used, almost 0 downtime during a migration) |
|
|
Term
| Scale-Out File Servers (SoFS) are not compatible with what features normally available in Windows Server 2012? |
|
Definition
| BranchCache, Data Deduplication, DFS Namespace servers, DFS Replication or File Server Resource Manager (FSRM) |
|
|
Term
| Dynamic Quorum does what? |
|
Definition
| Adjusts the votes to reach quorum automatically based on the # of active nodes. Cluster can remain active with only 1 active node. |
|
|
Term
| Windows Server 2012 has 2 types of file server roles for high availability. What are they? |
|
Definition
| "File server for general use" and a "Scale-Out File Server" for application data alternative |
|
|
Term
| What does the "Preferred Owner" setting do? |
|
Definition
| Determines which node,if available, should handle the client requests for a role both before and after node failure. |
|
|
Term
|
Definition
| Combines "Pause" and "Move Roles" steps from previous versions into one step. Right-click the node in cluster manager, choose "Pause" then "Drain Roles" |
|
|
Term
| Cluster-aware Updating setup to "Self Update" is managed where? |
|
Definition
| Cluster Manager, R-Click Cluster name, Select "More Actions" then Cluster-Aware Updating. Under Cluster Actions select "Configure cluster self-updating options". You will have to install "Cluster-Aware Updating(CAU) clusterd role." during the process. |
|
|
Term
| Failover Cluster Storage Pools cannot be thin provisioned, boot disks, or use RAID or parity. Based on the minimum disk requirement, what is the smallest disk capacity possible? |
|
Definition
| 12GB - a minimum of 3 physical disks with at least 4GB each is the minimum space allowed for a failover cluster storage pool. |
|
|
Term
| What do a role's "Startup Priority Settings" determine? |
|
Definition
| The order in which roles should be failed over and started after node failure. Choices are High, Medium-default, Low and No Auto Start which fails over after the other roles but does not start on the new node. |
|
|
Term
| Server 2012 enables live migration outside a clustered environment. What is required? |
|
Definition
Source and destination Hyper-V hosts are in domains that trust each other. An authentication method is required on both host servers-CredSSP or Kerberos.
DISADVANTAGE: migration takes much longer due to the copy process. |
|
|
Term
| Windows Server 2008 R2 failover clusters supported up to 16 nodes. How many can Windows Server 2012 support? |
|
Definition
|
|
Term
| By default, recovery properties for a monitored service on a Hyper-V VM automatically does what after it fails? |
|
Definition
| Restarts automatically after the first 2 failures. After the 3rd failure, the cluster service running on the Hyper-V host takes over recovery according to your monitoring configuration. |
