High Availability Flashcards
What values must you specify for the -PhysicalDiskRedundancy parameter and the -ProvisioningType parameter when using the New-VirtualDisk cmdlet to create a dual-parity space?
2 for the-PhysicalDiskRedundancy parameter and Fixed provisioning for the -ProvisioningType parameter
What four storage options are available for a failover cluster in Windows Server 2012 R2?
Serial attached SCSI
iSCSI
Fibre Channel
Shared VHDX
Which parameter would you use with the DFSRDIAG utility to force sysvol replication between two domain controllers?
SyncNow
When configuring guest clustering, what property must be configured the same on each virtual machine role that is part of the same guest cluster?
The AntiAffinityClassNames property
In a Windows Server 2012 R2 cluster, what cmdlet can you run to predetermine which node has its vote removed?
(Get-Cluster).LowerQuorumPriorityNodeID
What cmdlet should you run to view the vote status of a witness in a Windows Server 2012 R2 cluster?
(Get-Cluster).WitnessDynamicWeight
Why does Windows Server 2012 R2 increase the default threshold value for node health detection within a cluster from five seconds to 10 seconds if nodes are in the same subnet, and to 20 seconds if nodes are in different subnets?
To increase the resiliency for temporary network failures for virtual machines that are running on a Hyper-V cluster, and to delay cluster recovery actions in cases of short network interruptions.
How do live migrations of virtual machines differ between Windows Server 2008 R2 and Windows Server 2012?
With Server 2012, you can perform simultaneous live migrations of multiple virtual machines within a cluster
What values must you specify for the -NumberofDataCopies parameter and the -PhysicalDiskRedundancy parameter when using the New-VirtualDisk cmdlet to create a three-way mirror space?
specify 3 for the NumberofDataCopies parameter and 2 for the PhysicalDiskRedundancy parameter
Which heartbeat setting should you configure on a failover cluster to define the frequency at which cluster heartbeats are sent between nodes on the same subnet?
The SameSubnetDelay parameter
Why should you enable the CSV cache on a Scale-Out File Server?
CSV cache can boost the performance of read requests without caching writ requests
Which cmdlet can you run to configure high availability for a service that was not originally designed to run in a failover cluster?
Add-ClusterGenericServiceRole
Which heartbeat settings should you configure on a failover cluster to define the number of heartbeats that can be missed before the cluster takes recovery action?
The SameSubnetThreshold parameter and CrossSubnetThreshold parameter
Which feature of Windows Server 2012 R2 can adjust the cluster’s running node’s vote status automatically to keep the total number of votes in the cluster at an odd number?
Tie breaker for 50 percent node split
What feature introduced in Windows Server 2012 Hyper-V allows you import a virtual machine to a new host with different hardware without exporting the virtual machine?
the Import Wizard in Hyper-V Manager
When performing a rolling upgrade to Windows Server 2012 R2 on a Windows Server 2008 R2 SP1 NLB cluster, how many server nodes should you upgrade first?
You should upgrade a number of nodes that is between 1 and (N-1), where N is the number of nodes in the cluster
What are the three requirements of network adapters of hosts in an NLB cluster?
All network adapters must be on the same subnet
All network adapters must be configured with static IP addresses
All network adapters must be configured as either unicast or multicast
What should you do to each node in a Windows Server 2008 NLB cluster before performing a rolling upgrade to Windows Server 2012 R2?
Nothing. This upgrade is not supported.
When performing a rolling upgrade to Windows Server 2012 R2 on a Windows Server 2008 NLB cluster, how many server nodes should you upgrade first?
You cannot directly upgrade a Windows Server 2008 NLB cluster to Windows Server 2012 R2, only to Windows Server 2012
Which quorum configuration is recommended for failover clusters with an even number of nodes?
Node and Disk Majority
What steps would you need to perform an in-place upgrade of a failover cluster to Windows Server 2012 R2 from Windows Server 2008 R2 SP1?
Install Windows Server 2012 R2 and the cluster feature on one server
Create a new one-node failover cluster
Migrate settings from the old cluster to the new cluster
Install Windows Server 2012 R2 and the cluster feature on remaining server
Migrate resource groups and test failover
What are two ways to migrate failover cluster roles from one server to another?
Migrate cluster roles to a new cluster with new servers
Perform an in-place migration with only two nodes
In what circumstance should you NOT schedule password changes for cluster name objects and virtual computer objects during scheduled maintenance windows of a failover cluster?
To avoid interfering with a Cluster-Aware Updating (CAU) Updating Run that may be scheduled at the same time
Which cmdlet would you use to configure a file server as a scale-out file server?
Add-ClusterScaleOutFileServerRole
Which cmdlet can you run to configure high availability for an application that was not originally designed to run in a failover cluster?
Add-ClusterGenericApplicationRole
Which cmdlet allows you to pause a node to apply software updates to that node?
Suspend-ClusterNode
Which cmdlet turns on maintenance for a disk resource or Cluster Shared Volume so that you can run a disk maintenance tool without triggering failover?
Suspend-ClusterResource
What must you do to modify the write-back cache size of a virtual drive?
Delete the virtual hard drive and recreate the virtual drive the with the appropriate write-back cache size because you cannot modify the write-back cache size.
