  Explanation/Reference:

  A migration import allows data to be transferred from an existing storage platform to a Dell PowerStore cluster. The platforms that support migration import to a Dell PowerStore cluster include Unity, VNX2, Dell EqualLogic PS series and Dell Compellent SC Series. These platforms are EMC storage systems, which are now owned by Dell Technologies.

• Question 104:

  What is the minimum RPO that can be configured on a Dell Unity XT block-asynchronous replication session?

  A. 5 minutes
  B. 60 minutes
  C. 1 minute
  D. 20 minutes
  A. 5 minutes

  ---

  Explanation/Reference:

  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.

• Question 105:

• Question 107:

  A technical architect is helping a customer prepare for a data center maintenance window All applications must failover to the disaster recovery site The customer also wants to test their disaster recovery plan

  What PowerStore Manager replication option should be used to address the customer's need: and from which site should the option be run?

  A. Planned failover from target site
  B. Planned failover from source site
  C. Failover from target site
  D. Failover from source site
  B. Planned failover from source site

  ---

  Explanation/Reference:

  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.

• Question 108:

• Question 109:

  What is a benefit of using a performance assessment tool?

  A. Retrieves workload metrics from all storage systems
  B. Provides performance statistics in a structured postgres database
  C. Retrieves the performance archives using the Unity Data Collection
  D. Provides automated performance statistics in chart and table format
  D. Provides automated performance statistics in chart and table format

  ---

  Explanation/Reference:

  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.

• Question 110:

  A storage administrator plans to complete a technology refresh from a Dell EqualLogic PS6100 to a Dell EMC PowerStore array. The affected hosts are running native MPIO. What is the recommended method to support an import to PowerStore?

  B. Install EQL Hit Kit on the hosts
  C. Use Dell Storage Manager and select Online Import
  D. Install PowerStore ImportKit on the hosts
  D. Install PowerStore ImportKit on the hosts

  ---

  Explanation/Reference:
