• A. Is deleted
• B. Stays in read/write mode
• C. Stays in read-only mode
• D. Taken offline

Answer: C

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

Answer: 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.

What is a consequence of using an 800 GB drive and five 400 GB drives in a Dell EMC Unity XT dynamic pool?

• A. Extents 9 – 14 are used to create a RAID Group
• B. Unisphere short strokes the 800 GB drive to 8 extents
• C. Extents 9 – 14 are marked unavailable until more 800 GB drives are added
• D. Extents 9 – 14 are marked unavailable and can never be recovered

Answer: C

Explanation:
The entire capacity of a particular drive size is only available when the drive count within the drive partnership group for the drive in question matches or exceeds the stripe width plus one drive. It is not recommended to mix different size drives of the same type for this reason, unless an adequate number of drives are available to meet or exceed the stripe width plus one drive requirement
