Correct Answer: C

DELL PDF document about dynamic pools: h16289-dell_emc_unity-dynamic_pools.pdf Page 20-21. The smallest RAID 5 stripe width the system supports is a 4+1. The smallest dynamic pool created with the RAID 5 4+1 configuration is 6 drives. The minimum drive count includes the number of drives specified in the stripe width, plus the hot spare capacity. The hot spare capacity is selected by the user at pool creation, and can either be set to 1 or 2 drives for every 32 drives in the pool.

Correct Answer: B

Choosing the highest capacity flash drives when designing a Dell Unity XT All-Flash system can provide several benefits, including lower physical space, power and cooling requirements. Additionally, higher capacity drives can also improve system boot time, reduce maintenance and rebuild time, and decrease wear-leveling, performance, and redundancy requirements.

Correct Answer: B

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.

Correct Answer: D

A performance assessment tool is used to evaluate the performance of storage systems and provide statistics that can be used to identify and troubleshoot performance issues. One of the benefits of using a performance assessment tool is that it provides automated performance statistics in chart and table format, making it easy to understand performance metrics and identify any potential issues. This allows the user to quickly identify and address any bottlenecks in the system, and make adjustments to improve performance.

Correct Answer: C

Asynchronous replication can be used to replicate data over larger distances than synchronous replication. However, it cannot be used to replicate data between two UnityVSA systems within the same city. To replicate file data from a production Dell Unity 550F to a remote office in the same city with a UnityVSA, the technical architect should advise the customer to use synchronous replication.

Correct Answer: B

7% is the recommended minimum amount of Flash that a technical architect should specify when designing a Dell Unity XT 480 using the System Designer option of Sizer. This is because, Unity XT storage systems require a certain amount of flash storage to handle system-wide functions such as metadata, snapshots and other storage services.

Correct Answer: B
