A. VMware Cloud on AWS
B. VMware Horizon
C. VMware Aria Automation
D. Tanzu Kubernetes Grid Integrated Edition
Q32. An administrator has deployed a new vSAN OSA cluster that contains eight hosts and needs to configure a storage policy for the currently deployed database virtual machines. The requirements state that if two hosts in the vSAN OSA cluster fail, all virtual machines are unaffected. Which RAID configuration must the administrator use in this storage policy to achieve the best performance for the database virtual machines?
Q33. Which vSAN maintenance mode option should be used to avoid storage policy non-compliance?
A. Ensure accessibility
B. Partial maintenance mode
C. Full data migration
D. No data migration
Q34. A vSAN administrator needs to enable vSAN ESA. Which two requirements need to be met? (Choose two.)
A. vSAN Build Your Own configuration
B. vSAN Standard license
C. vSAN Witness Appliance
D. vSAN Advanced license
E. vSAN ReadyNodes configuration
Q35. A three-node vSAN OSA cluster with business critical intensive I/O workload is running out of capacity. Each host consists of five disk groups with four capacity disks. The administrator needs to expand the capacity of the vSAN datastore as soon as possible. What should the administrator do?
A. Enable Deduplication and Compression on the cluster level
B. Add additional capacity by adding a disk on one host and creating a storage pool
C. Add additional capacity by adding a vSAN ReadyNode to the cluster
D. Add additional capacity disks to each disk group
Q36. An administrator is responsible for managing a five-node vSAN cluster. The vSAN Cluster is configured with both vSphere High Availability (HA) and vSphere Distributed Resource Scheduler (DRS). The vSAN Cluster is currently hosting 150 virtual machines that have consumed 60% of the usable capacity. Each virtual machine belongs to one of the following vSAN Storage Policies: vSANPolicy1:
Site Disaster Tolerance: None –
Failures to Tolerate: 1 failure – RAID-5 (Erasure Coding)
Site Disaster Tolerance: None –
Failures to Tolerate: No data redundancy
Following an unplanned power event within the data center, the administrator has been alerted to the fact that one host has permanently failed.
What will be the impact to any virtual machine that was running on the failed host using vSANPolicy1?
A. Each virtual machine will be restarted on another vSAN host using vSphere HA.
B. Each virtual machine will be unavailable for up to 90 minutes while the automatic recovery process completes.
C. vSAN will defer the start of the recovery process for 60 minutes, and the virtual machines will not power on until the recovery process has been completed.
D. Each virtual machine must be restored from backup.
Q37. What are two characteristics of a durability component in vSAN? (Choose two.)
A. Better Performance
B. Faster resynchronization
C. Faster snapshot creation
D. Better Storage utilization
E. Better Availability
Q38. A vSAN administrator is responsible for managing a customer’s production vSAN cluster that is going to be used to provide SMB file shares to a number of host clients. The vSAN administrator must take action so the performance of all services in the production vSAN cluster can be monitored. Which two services must be enabled for this monitoring to occur? (Choose two.)
A. vSAN Performance Diagnostic Service
B. iSCSI Target Service
C. vSAN File Services
D. vSAN Health Service
E. vSAN Performance Service
Q39. During yesterday’s business hours, a cache drive failed on one of the vSAN OSA nodes. The administrator reached out to the manufacturer and received a replacement drive the following day. When the drive failed, vSAN started a resync to ensure the health of the data, and all objects are showing a healthy and compliant state. The vSAN administrator needs to replace the failed cache drive. Which set of steps should the vSAN administrator take?
A. Physically replace the failed cache device, and vSAN will automatically create a new disk group. Then, remove the disk group with the failed device.
B. Place the disk group into maintenance mode, and select Full Data Migration. Then, physically replace the failed cache device. Afterwards, vSAN will rebuild the disk group automatically.
C. Remove the existing vSAN disk group, and physically replace the device. Then, check to verify that the ESXi host automatically detects the new device. Afterwards, manually recreate the Disk Group.
D. Physically replace the failed cache device, and vSAN will automatically allocate the storage. Then, rebalance the cache layer.
Q40. What are two prerequisites for using the TRIM and UNMAP capability of vSAN? (Choose two.)
A. Deduplication and compression are enabled.
B. The vSAN cluster is an all-flash architecture.
C. The VM guest operating system supports ATA TRIM or SCSI UNMAP capability.
D. TRIM and UNMAP is enabled.
E. Change the Object Space Reservation to 100.
Q41. An administrator is upgrading multiple vSAN Witness nodes with vLCM (single image management) that are used for vSAN Stretched and two-node Clusters. What two witness node types can the administrator upgrade? (Choose two.)
A. Appliance witness node
B. Shared witness node
C. Nested witness node
D. Dedicated witness node
E. Physical witness node
Q42. An administrator is troubleshooting a vSAN performance issue. In the vSAN performance monitor there is a high latency on the vSAN cluster. What is a possible cause of this?
A. The Virtual Machines are using PVSCSI controllers.
B. Erasure Coding is disabled in the storage policy.
C. There is congestion in one or more disk groups.
D. Jumbo frames are not enabled on the VMkernel adapters.
Q43. Refer to the exhibit. An administrator uses SSH to log into a vSAN ESA host and runs the esxcli vsan debug object overview command.
The administrator notices the Healthy Components column, the last column, is reporting some components are not in a fully healthy state. What could cause this behavior?
A. New physical disks have been claimed and a rebalance operation is underway.
B. The applied Storage policy has been updated.
C. New VMDKs have been added to multiple VMs, but the storage policy has not finished applying.
D. One host is in maintenance mode with ensure accessibility.
Q44. A vSAN administrator is using the vSAN ReadyNode Sizer to build a new environment. While entering the cluster configurations, a fellow colleague inquires about the Operations Reserve option. What is the purpose of using this option?
A. Provides space for internal operations
B. Configures space for external operations
C. Reserves space for tolerating failures
D. Allocates space for vSAN upgrades
Q45. Which two actions are recommended when adding a host to a vSAN cluster? (Choose two.)
A. Create uniformly-configured hosts
B. Disable vSAN performance service
C. Disable vSphere Cluster Services (vCLS)
D. Disable vSphere High Availability (HA)
E. Reference the VMware Compatibility Guide
