D-RP-OE-A-24 practice question 6 of 15

If a VPLEX distributed device is selected during the RecoverPoint Consistency Group Creation wizard, which option will appear?

Full set: 62 questions
Answer options
A: Section to define production and replica Journals on unregistered storage arrays
B: Radio button to select which cluster will be the winning cluster upon the initialization of the Consistency Group
C: List of LUNs which are less than 10 TBs in size; the size limit for distributed devices
D: Ability to create a MetroPoint Consistency Group Correct answer
Correct Answer:
D. Ability to create a MetroPoint Consistency Group
Explanation

A MetroPoint topology is a three-site configuration that combines VPLEX Metro for high availability with RecoverPoint for continuous data protection (CDP) and continuous remote replication (CRR). The foundation of this topology is a VPLEX distributed device, which serves as the production volume. When the RecoverPoint Consistency Group (CG) creation wizard detects that a selected production LUN is a VPLEX distributed device, it recognizes the potential for a MetroPoint configuration. Consequently, the wizard presents the specific options required to create a MetroPoint Consistency Group, which involves configuring the two local copies (one at each VPLEX cluster) and a third remote copy for disaster recovery.

Why Incorrect

A. RecoverPoint requires storage arrays to be registered and managed by the splitter to intercept I/O for replication. It cannot use unregistered storage for journals or replicas.
B. The "winning cluster" is a fundamental property of the VPLEX distributed device, configured within VPLEX to handle split-brain scenarios. RecoverPoint does not set this property during CG creation.
C. While LUNs have size limits, the wizard does not present a filtered list based on a specific 10 TB limit as the primary option when a distributed device is selected.

Page 5, Section "MetroPoint overview": "MetroPoint is a three-site configuration that combines Dell EMC VPLEX Metro continuous availability with Dell EMC RecoverPoint continuous data protection (CDP) and continuous remote replication (CRR)... The production application data resides on a VPLEX Metro distributed volume..." This document establishes that selecting a distributed volume is the prerequisite for a MetroPoint configuration.

Page 121, Section "Protecting virtual machines in a VPLEX Metro environment": "When protecting VMs that reside on a VPLEX Metro distributed datastore, you can create a MetroPoint consistency group..." The guide then details the wizard steps, which are unique to this topology, confirming that the option appears upon selecting the distributed device.
