Correct Answer: C

This option provides the smallest drive configuration possible for both the 3000T and 9000T models, and allows for single drive upgrades, which is more flexible for the customer.

Correct Answer: A

The minimum RPO (Recovery Point Objective) that can be configured on a Dell Unity XT block-asynchronous replication session is 5 minutes. RPO is a measure of how much data can be lost in the event of a disaster, and it's typically measured in minutes. The lower the RPO, the less data can be lost. Block-asynchronous replication is a replication method that copies data blocks, rather than files, between the source and the target. The data is copied at regular intervals, and if a disaster occurs at any point in time, the data on the target will be no more than 5 minutes old. The shorter the RPO, the more frequently data is copied and the less data is at risk of being lost in case of a disaster. It's important to note that this is the minimum RPO for block-asynchronous replication, it can be set to a higher value if needed.

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: B

"As a standard, tier 3 drives should encompass a minimum of 20% system IOPS potential."

Correct Answer: C

"Removing a replication session is initiated on the source system by removing the protection policy from the Volume or Volume Group on the source system. Removing the protection policy from a storage resource results in the following: * The destination storage resource stays in read-only mode."

Correct Answer: D

The System Designer path of the size tool for Dell Unity XT uses predefined configurations that are based on array model capacity points, random workloads RAID type and drive type. This path is designed to make the sizing process quick and easy, providing recommended configurations that are optimized for specific array models and workloads. It allows the user to select an array model, and then it will provide a set of predefined configurations that meet the desired capacity, performance, and availability requirements.

Correct Answer: A

An administrator can use a user quota to limit the amount of storage that the user consumes on a Dell PowerStore system. A user quota is a limit that is set on the quota tree, which is a hierarchical structure that organizes storage resources and sets limits on how much storage can be used at each level. The user quota is applied to a specific user or group of users and limits the amount of storage that can be consumed by that user or group of users.

Correct Answer: B

In this scenario, the customer wants to test their disaster recovery plan and wants all applications to failover to the disaster recovery site. To accomplish this, the technical architect should use the planned failover option from the source site, the primary site. This will allow the customer to test their disaster recovery plan and ensure that all applications can be successfully failed over to the disaster recovery site. It's important to note that if the customer wants to failover to the disaster recovery site for maintenance and after that fail back to the primary site, the planned failover should be run from the target site.
