An architect is tasked to design a VMware Horizon Solution with vSAN. The architect needs to use a solution to host the user's profile shares in a highly available manner, and it must be guest OS independent.
Which solution will match these requirements?
An administrator managing a vSAN cluster of six-nodes with policy FTT-2/RAID-6 decided to put one of the nodes in maintenance mode using the ''Full-data migration'' option.
What will happen after this action is taken?
https://blogs.vmware.com/virtualblocks/2020/02/06/what-happens-vsan-host-in-maintenance-mode/ Let's take a look at a few unique scenarios with regard to maintenance mode. First, let's see what will happen if you have 6 hosts within your cluster, you have applied a policy containing FTT=2/RAID-6, and you want to place a host in maintenance mode using the 'Full data migration' option. This means all the data residing on the host will be evacuated to another host within the cluster. With this type of data configuration, the system will prompt you to add an additional host to the cluster in order to preserve the policy compliance. The policy will always require there must be two failures that can be tolerated, even during cluster reduction due to maintenance mode removing a host. Note that a minimum of six hosts is required to support a storage policy with RAID-6(FTT=2) erasure coding
A company hosts a vSAN 7 stretched cluster for all development workloads. The original sizing of a maximum of 250 concurrent workloads in the vSAN cluster is no longer sufficient and needs to increase to at least 500 concurrent workloads within the next six months.
To meet this demand, the original 8-node (4-4-1) cluster has recently been expanded to 16 nodes (8-8-1).
Which three additional steps should the administrator take to support the current growth plans while minimizing the amount of resources required at the witness site? (Choose three.)
An administrator is planning to deploy workloads on a six node vSAN cluster, and all nodes are distributed equally across three racks.
Which action is required to ensure that the workload VMs remain compliant with the default vSAN policy after a complete rack failure?
Adding an additional rack with two hosts and configuring vSAN with four fault domains and FTT=1 (mirroring) will ensure that the workload VMs remain compliant with the default vSAN policy after a complete rack failure. This is because FTT=1 (mirroring) will provide the highest level of redundancy and ensure that if one rack fails, the other racks can still provide the necessary data to remain compliant.
An administrator is tasked to create a custom storage policy for workloads and is including additional disk stripes while defining the storage policy.
What is the main purpose of this practice?
