Each question shows the correct answer and an explanation of why it is right
A customer is planning to migrate their physical Microsoft SQL Server clustered workloads to vSAN enabled vSphere clusters.
The following requirements must be met:
* Each MSSQL cluster is made up of 3 nodes
* Highest possible availability against node failures
* Some of the vSAN clusters will only consume storage
What should the architect recommend?
vSAN 6.7 expands the functionality of the vSAN iSCSI Target service to provide the SCSI-3 persistent reservations support for shared disks for windows failover cluster if using the SQL Server FCI, high availability mode is a requirement. The vSAN iSCSI Target service at the vSAN cluster level should be enabled for this purpose. VSAN streched cluster may be used to increase the data availability across data centres. https://blogs.vmware.com/virtualblocks/2019/03/26/considerations-for-running-microsoft-sql-server-workloads-on-vmware-vsan/
A 30-minute power maintenance window has been approved on Sunday. Due to a delay, the maintenance took 20 minutes longer to finish.
During this time, the vSAN administrator noticed that one of the clusters nodes was affected by a power shortage, as it was connected to an affected power source. The default vSAN storage policy has been applied.
What will be the status of the vSAN objects on the affected host immediately after it is recovered?
Default Storage Policy is FTT=1. https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.virtualsan.doc/GUID-C228168F-6807-4C2A-9D74-E584CAF49A2A.html
An architect is designing a vSAN cluster.
Which storage controller option will yield optimal performance?
Storage Controller Queue Depth There are two important items displayed by the VCG for storage I/O controllers that should be noted. The first of these is ''features'' and the second is queue depth. Queue depth is extremely important, as issues have been observed with controllers that have very small queue depths. In particular, controllers with small queue depths (less than 256) can impact virtual machine I/O performance when vSAN is rebuilding components, either due to a failure or when requested to do so when entering maintenance mode. Design Decision : Choose storage I/O controllers that have as large a queue depth as possible. While 256 are the minimum, the recommendation would be to choose a controller with a much larger queue depth where possible. https://core.vmware.com/resource/vmware-vsan-design-guide#sec6843-sub14
An administrator is setting up vSAN file services on a vSAN cluster but is unable to join the vSAN File Services to the domain.
Which two possible reasons could explain this failure? (Choose two.)

An architect is working with an All-Flash vSAN configuration and will be using the Flash Caching Devices in vSAN.
Which requirement is specifically needed for these devices?
In all-flash configurations, vSAN uses the cache layer for write caching only. The write cache must be able to handle high write activities. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan-planning.doc/GUID-1D6AD25A-459A-43D6-8FF5-52475499D6A2.html
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?
Os independent is the requirements and High Availability. So vSAN 7 enable NFS and SMB on s SPBM cluster in wich Windows, Linux and MAC could have user profile with business continuity. Ref: https://core.vmware.com/blog/redirecting-user-profiles-and-data-using-fslogix-and-vsan-file-services
7 domains from the VMware 5V0-21.21 exam outline, with approximate weightings. Every sample question above is tagged with the domain it comes from
There are no testable objectives for this
Identify the VMware products and solutions that will interact with and consume a vSAN solution in a given scenario. Understand how vSAN integrates with the broader VMware ecosystem.
Design appropriate vSAN clusters and services for specific scenarios. Use vSAN design and sizing tools including sizing cache tier for workload, node count, VM sizing, Live Optics, and HCI Bench.
There are no testable objectives for this
Identify appropriate vSAN upgrade methodology and maintenance mode options. Manage disks and disk groups effectively in a vSAN deployment.
Sample question from this domain above: Q2
Recover from vSAN and infrastructure failures. Troubleshoot performance issues and stretched vSAN cluster problems. Evaluate performance information using the UI and vsantop.
Manage vSAN data placement changes including stretched clusters and fault domains. Manage encrypted vSAN deployments and storage policy changes. Manage stretched vSAN clusters operationally.
