D-RP-OE-A-24 Exam Dumps : Dell RecoverPoint Operate Achievement

In a Distributed Consistency Group (DCG) configuration, the primary RPA and secondary RPAs work together to manage a larger data throughput than a single RPA can handle. This is achieved by dividing the workload among multiple RPAs. As a result, there is an increase in traffic observed on the WAN network between the RPAs.This is because the data that is being replicated needs to be transferred over the WAN to ensure that all RPAs have the necessary information to maintain consistency and data protection1.

The process involves:

The primary RPA receives write I/Os from the production environment.

The primary RPA then distributes the data to the secondary RPAs over the WAN.

The secondary RPAs process the data and replicate it to their respective Journal volumes.

This distribution of workload allows the DCG to handle higher throughput and IOPS rates than a single RPA could manage1.

It’s important to note that while there is additional traffic on the WAN, this does not necessarily mean that the FC (Fibre Channel) links or management network are unaffected.However, the most significant increase in traffic is observed on the WAN network, which is the communication link between the RPAs in a DCG configuration1.

In a Dell RecoverPoint system with XtremIO arrays at both production and disaster recovery sites, setting the replication mode for a Consistency Group as “Continuous” implies that the replication occurs continuously without predefined intervals. This mode aims to minimize the Recovery Point Objective (RPO), which is the maximum targeted period in which data might be lost due to a major incident. While an RPO of 0 seconds is ideal, it is often not practical due to network latency and system processing times.Therefore, an effective RPO of less than 60 seconds is a realistic target for a “Continuous” replication mode, ensuring that data loss is minimized to the lowest possible timeframe in the event of a disaster1.

Questions no:What will be the replication state between the new production and former production when the administrator selects “Set Copy as Production”?

Verified Answer:When “Set Copy as Production” is selected, the failover replica copy is confirmed as the new Production and initiates replication to additional replicas other than the original Production copy which is already receiving writes after the failover1. This means that the replication state between the new production and former production would involve initiating replication to the additional replicas.

Step by Step Comprehensive Detailed Explanation with References:

Failover Occurs: The administrator initiates a failover, which involves switching the roles of the production and non-production copies.

Set Copy as Production: The administrator selects the “Set Copy as Production” option, which confirms the failover replica copy as the new Production.

Replication Initiated: Replication is initiated to additional replicas, excluding the original Production copy, which continues to receive writes after the failover.

State of Former Production: The former production copy, now a replica, will be in a state where it is receiving the replicated data from the new production copy.

This process ensures that the data protection and replication continue seamlessly after the failover, with the new production copy taking over the role of the source for replication1.
