Question #22
What result is obtained by multiplying the VM count by the Capacity per VM in a PowerStore system?
- A . Usable Capacity
- B . Raw Capacity
- C . Effective Capacity
Correct Answer: A
A
Explanation:
In a PowerStore system, multiplying the VM count by the Capacity per VM gives the Usable Capacity. Usable Capacity represents the actual storage capacity available for use by the virtual machines, taking into account any overheads, data protection mechanisms, and efficiency features such as deduplication and compression.

Question #25
How are vVol datastores mounted in Dell EMC PowerStore storage during the creation of vVol datastores in the vSphere environment shared by ESXi hosts?
- A . Volume Groups
- B . Storage containers
- C . Storage Groups
- D . VMFS datastores
Correct Answer: B
B
Explanation:
A storage container is used to present vVol storage from a PowerStore cluster to vSphere. vSphere mounts the storage container as a vVol datastore and makes it available for VM storage. When a PowerStore cluster is used to provide VM storage, user VMs should be provisioned on the vVol datastores. The default storage container is mounted automatically on the nodes of the cluster.

Question #27
What is a Dell recommendation when connecting ESXi hosts to PowerStore?
- A . Use the default 8K host I/O size when using NFS
- B . Configure a minimum of two NAS server when using vVol Datastores
- C . Enable Delayed ACK when configured using iSCSI
- D . Configure Round Robin Multipathing with an IOPS limit of 1024
Correct Answer: B
Question #28
What is one key difference between deduplication on Dell PowerStore and Dell Unity?
- A . Unity has no deduplication function
- B . Unity data reduction cannot be disabled
- C . Deduplication block size is smaller on PowerStore than on Unity
- D . Deduplication block size is larger on PowerStore than on Unity
Correct Answer: C
C
Explanation:
Deduplication is a feature that reduces storage capacity usage by eliminating duplicate data. PowerStore and Unity both have deduplication function, but one key difference is the size of the deduplication block. PowerStore uses a smaller block size which allows for a higher level of granularity and more efficient deduplication. On the other hand, Unity uses a larger block size which is less granular, but it is still efficient for large sequential data workloads.
