A vSAN Administrator has a cluster of six vSAN nodes. The vSAN datastore was 55% utilized, and due to a power outage, one node was lost. The vSAN administrator needs to resolve the storage policy compliance for the virtual machines on RAID-5.
Which action, if any, needs to be taken to meet this goal?
When a node is lost in a vSAN cluster, the vSAN will automatically begin to rebuild objects in order to meet the storage policy compliance. However, if the storage policy includes RAID-5 with a 'Failures to Tolerate' (FTT) value of 2, it won't be possible to rebuild the objects and meet the storage policy compliance with only 5 nodes. In this case, the vSAN administrator needs to change the RAID-5 FTT from 2 to 1, this will allow the vSAN to rebuild the objects and meet the storage policy compliance with only 5 nodes. With RAID-5, the FTT value of 1 is the minimum value supported by vSAN.
A vSAN storage policy with the 'Failures lo Tolerate" rule set to "2 failures - RA1D-1 {Mirroring)" is assigned to multiple virtual machines.
The vSAN administrator is considering assigning a new vSAN storage policy with the "Failures to Tolerate' rule set lo '2 failures - RAID-6* (Erasure Coding)" to the virtual machines.
How will the capacity of the vSAN datastore be affected if this action is taken?
Used capacity will increase temporarily while the erasure coded components are built. When a vSAN storage policy with 'Failures to Tolerate' set to '2 failures - RAID-6 (Erasure Coding)' is assigned to multiple virtual machines, the components of the objects stored on the vSAN datastore will be rebuilt in an erasure coding format, which requires additional capacity. This additional capacity will be used temporarily while the erasure coded components are built, and will be reclaimed once the process is complete.

According to the VMware vSAN documentation, when a vSAN storage policy with 'Failures to Tolerate' set to '2 failures - RAID-6 (Erasure Coding)' is assigned to multiple virtual machines, the components of the objects stored on the vSAN datastore will be rebuilt in an erasure coding format, which requires additional capacity. This additional capacity will be used temporarily while the erasure coded components are built, and will be reclaimed once the process is complete.
A vSAN administrator is looking at adding a new vSAN cluster with hosts that have 512GB memory.
What is the minimum requirement for the node's flash boot device?
An administrator has discovered that space utilized by VMs does not decrease after deleting files and folders within the VMs. The administrator needs to be able to reclaim this space.
Which action could the administrator take to accomplish this task?
A vSAN administrator has been asked to increase the usable storage capacity of an existing vSAN cluster to deploy some new virtual machines containing a large amount of dat
a. The details are as follows:
* Each ESXi host in the vSAN cluster is configured with two disk groups.
* Each disk group contains three capacity devices and one cache device.
* Deduplication and compression are not enabled.
* Only the default VM storage policy is in use and had not been changed.
* Add capacity without re-creating disk groups.
The company would like to minimize the number of devices used for cost Optimization.
Which action should the vSAN administrator carry out to provide additional storage to the vSAN cluster?
In order to increase the usable storage capacity of an existing vSAN cluster without re-creating disk groups, the vSAN administrator should add new capacity devices to the existing disk groups. This will allow additional storage to be added to the vSAN cluster while minimizing the number of devices used for cost optimization.
