[Oct-2023] 5V0-21.21 exam torrent VMware study guide [Q18-Q34]

Q18. An administrator is tasked with migrating a VMware Horizon View environment that is currently running on an NFS Datastore to VMware vSAN.
Which Horizon configuration option will not be available when configuring vSAN in Horizon View?

Q19. An administrator is setting up vSAN file services on a vSAN cluster.
Which two security policies on the distributed port groups are automatically enabled in the process? (Choose two.)

Q20. An administrator wants to enable encryption on an existing vSAN cluster that already contains virtual machines.
Which additional step should the administrator take to ensure no data is lost during the encryption process?

Q21. A company has deployed a 12-node (6-6-1) vSAN 7.0 stretched cluster for all production workloads.
The customer currently uses four different vSAN storage policies for running the workloads depending on the applications requirements:
* Policy 1 – Site Disaster Tolerance=Dual Site Mirroring, FTT=Erasure Coding
* Policy 2 – Site Disaster Tolerance=Dual Site Mirroring, FTT=Mirroring
* Policy 3 – Site Disaster Tolerance=None – Keep Data on Preferred, FTT=Mirroring
* Policy 4 – Site Disaster Tolerance=None – Keep Data on Non-Preferred, FTT=Mirroring During the setup of the vSAN stretched cluster, the following VM/Host Rules were created:
* Preferred Site – Preferred Site workloads should run on DC1 hosts.
* Secondary Site – Secondary Site workloads should run on DC2 hosts.
Which two activities should the administrator complete to ensure that there is no impact to production services during the maintenance window in the Preferred Site? (Choose two.)

Q22. A customer is planning to deploy a vSAN cluster to host their in-house distributed ERP system. The hardware specifications for their server nodes include:
* 2 x Intel Xeon CPU E5-2697 v3 @ 2.60GHz
* 1TB memory
Which boot device is supported for the vSAN ESXi nodes for this customer?

Q23. cluster for a customer who is planning to use vRealize Automation to provision 600 virtual machines into that cluster, with expected growth up to 1,000 VM. Each VM has a 40GB thick-provisioned disk.
Which flash disk size is required for the cache tier per ESXi node to meet all requirements?

Q24. An administrator is setting up vSAN file services on a vSAN cluster.
Which two security policies on the distributed port groups are automatically enabled in the process? (Choose two.)

Q25. An architect collected the below technical requirements from the customer during a vSAN cluster design workshop:
* Maximize the vSAN datastore usable capacity.
* Deduplication and compression are required to help utilize available capacity efficiency.
* Ensure the highest level of resiliency wherever possible.
Which disk group configuration should the architect include in the design?

Q26. An administrator is tasked with setting up Kerberos authentication only for the vSAN File services.
Which version of Kerberos must be selected if the NFS version is v4.1?

Q27. A customer has upgraded to vSAN 7, but there is still an existing legacy host which must be removed from the vSAN cluster.
Which three steps must an administrator take to successfully remove this host from the vSAN cluster? (Choose three.)

Q28. Due to the success of the recently deployed developer-only private cloud solution, a company has a new requirement to at least double the usable capacity in their all-flash vSAN cluster.
The vSAN cluster is deployed into a co-located datacenter that is owned by a third-party hosting company. The hosting company charges a fixed monthly cost for rack space and power consumption. The service owner has been given a limited budget for additional hardware purchases, but not for on-going co-location costs.
The current vSAN cluster has the following configuration:
* 10 vSAN Nodes with 2 CPUs (20 cores), 512 GB RAM
* 1 Disk Group per vSAN node
– 1 x 400 GB
– 4 x 1.8 TB
* De-duplication and Compression is enabled.
* vSAN Capacity is currently:
– Total: 72 TB
– Usable: ~40 TB (FTT1/RAID1) and ~60 TB (FTT1/RAID5).
As a result of any action taken, the service owner would like to ensure that overall availability of the vSAN cluster is increased.
Which two recommendations meet the requirement to increase capacity while maintaining service availability? (Choose two.)

Q29. In a vSAN stretched cluster, which value must be set in the vSAN policy if there is no requirement for data mirroring across sites?

Q30. 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?

Q31. An 8-Node vSAN Stretched Cluster (4+4+1) with a single disk group has a policy with PFTT=1 (mirrored across sites) and SFTT=1/FTM Mirroring (Local Protection) configured.
The administrator has been alerted that there is a problem with the cluster. The following has been observed:
* The vSAN Witness Host is offline.
* Two disk failures on two hosts have occurred in the preferred site.
This has resulted in a critical production virtual machine’s vmdk becoming inaccessible.
Which step needs to be performed by the administrator to resolve the issue?

Q32. 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?

Q33. Upon investigating a workload performance issue, a vSAN administrator observed a high backend IOPs on a vSAN cluster.
Which two causes explain this behavior? (Choose two.)

Q34. An administrator has been tasked with enabling encryption for existing virtual machines on a vSAN cluster.
Which three prerequisites must be satisfied before completing the task? (Choose three.)
