NEW QUESTION 8
What is a benefit of cross-platform replication between Dell EMC SC Series and Dell PS Series arrays?

• A. Leverages existing interfaces
• B. Enables replication of volume collections
• C. Supports cascade mode for the PS Group
• D. Provides active snapshot replication

Answer: A

NEW QUESTION 9
What are characteristics of D@RE on a Dell EMC Unity array?

• A. Impacts array only during implementation Has minimal impact on performance
• B. Does not impact array during implementation Has some impact on performance for a moment
• C. Impacts array for a moment after implementation Has no impact on performance
• D. Does not impact array during implementation Has minimal impact on performance

Answer: D

Explanation:
controller-based D@RE has minimal performance impact for typical mixed workloads, and no impact to other Dell EMC Unity data services due to the level at which the encryption is performed, which is after all data services have been applied.

NEW QUESTION 10
What provides data analytics for Dell EMC Midrange storage?

• A. eLab Advisor
• B. Unisphere Central
• C. DSM
• D. CloudIQ

Answer: D

NEW QUESTION 11
What are the two biggest factors that determine IOPS when using SSDs in a Dell EMC SC Series array?

• A. Current latency and queue depth
• B. Application block size and overall throughput
• C. Multi-tenant arrays and tier configuration
• D. Read/write percentage and peak workload

Answer: B

Explanation:
The reason there is such a large range in the number of IOPS delivered by SSDs is the IOPS are truly dependent on the type of traffic the SC Series was designed to handle. The two biggest factors that will determine IOPS in an SSD environment are block size of the application and overall throughput.

NEW QUESTION 12
How many PCI-E lanes are provided for Slot 0 and Slot 1 in Dell EMC Unity XT arrays?

• A. 8 for Slot 0; 8 for Slot 1
• B. 16 for Slot 0; 16 for Slot 1
• C. 8 for Slot 0; 16 for Slot 1
• D. 16 for Slot 0; 8 for Slot 1

Answer: D

NEW QUESTION 13
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.

NEW QUESTION 14
