Answer : B

To integrate Site Recovery Manager (SRM) with RecoverPoint, the storage replication adapter is a critical component that allows SRM to manage RecoverPoint replication properly. The installation steps are as follows:

Identify SRM Servers: Determine which servers are running the VMware Site Recovery Manager service.

Install SRA: Install the RecoverPoint SRA on each of the SRM server hosts at both the recovery and protected sites.

Verify Installation: Ensure that the SRA is correctly installed and recognized by the SRM service.

Configure Replication: Use the SRA within SRM to configure and manage replication settings for disaster recovery.

It's important to use the most current version of the SRA to ensure optimal compatibility and available features. The SRA can be downloaded from the VMware website, and the SRA release notes and product documentation should be consulted to determine compatibility with SRM versions1.

Answer : C

In a Dell RecoverPoint environment, Direct Access mode allows for write access to a replica volume during testing or other scenarios. However, when using XtremIO arrays, Direct Access mode is not available because XtremIO handles replication differently compared to other array types. Instead, XtremIO uses its snapshot technology, which does not support Direct Access in the same way as traditional replication methods1.

Here's why Direct Access is limited with XtremIO:

XtremIO Snapshot Technology: XtremIO arrays use snapshot technology for replication, which is different from the replication methods used by other array types like VMAX, VNX, or VPLEX.

Direct Access Mode: This mode typically allows a replica volume to be mounted and written to directly, but due to the way XtremIO handles snapshots, this functionality is not supported.

RecoverPoint Integration: RecoverPoint integrates with XtremIO to provide replication and disaster recovery solutions, but the Direct Access feature is not compatible with XtremIO's snapshot-based replication1.

Therefore, when using XtremIO arrays in a RecoverPoint environment, administrators need to be aware of this limitation and plan their disaster recovery and testing strategies accordingly1.

Answer : C

To meet the requirement of keeping a local copy of the production data in a RecoverPoint environment with VNX(SE) clusters, the administrator can add a local copy into the existing Consistency Group. This action does not require deleting and reconfiguring the existing Consistency Group or upgrading the license. Here are the steps:

Access Unisphere for RecoverPoint: Log into the Unisphere interface for RecoverPoint management.

Navigate to the Consistency Group: Find the Consistency Group that needs the local copy.

Add a Local Copy: Use the option to add a copy into the selected Consistency Group.

Configure the Local Copy: Specify the settings for the local copy, such as the Journal volume and RPO settings.

Apply Changes: Save the changes to implement the local replication.

This process allows the administrator to enhance the data protection strategy by adding a local copy for operational recovery or other business needs without disrupting the existing remote replication setup1.

Answer : B

Changing the link compression setting on a RecoverPoint Consistency Group can result in a temporary high-load on the system. This is because when compression is enabled or settings are changed, the system needs to compress the existing data before it can be transmitted, which requires additional processing power and can temporarily increase the load on the RecoverPoint Appliances (RPAs).

The process involves:

The administrator changes the link compression setting in the Consistency Group configuration.

The RPAs begin compressing the data that needs to be replicated across the network.

This compression process increases the CPU and memory usage on the RPAs, leading to a temporary high-load situation.

Once the initial compression is completed, the system load returns to normal levels, and replication continues with the new compression setting in effect.

It's important to note that while the system is under high-load, there might be a temporary impact on performance, but this does not affect the integrity of the replication or the Journal history. The system is designed to handle such temporary increases in load without losing any critical data1.

Answer : B

The performance of the Journal volumes at the remote copy can significantly affect the time it takes for a Consistency Group to complete the first-time initialization. The Journal volumes are where all the changes to the protected volumes are recorded before they are replicated to the remote site. If the Journal volumes are performing poorly, due to issues like high latency or low IOPS (Input/Output Operations Per Second), it can slow down the initialization process as the system struggles to record and replicate the data efficiently1.

Other factors such as the distance between the production and remote copy clusters and the number of RecoverPoint Appliances (RPAs) at both the production and remote copy clusters can also influence the initialization time. However, these factors typically affect the ongoing replication performance rather than the initial synchronization. The number of RPAs can impact the system's ability to process and replicate data, but the most direct impact on initialization time is the performance of the Journal volumes, as they are the bottleneck in the data recording process1.

Answer : A

EMC AppSync is the product that integrates with RecoverPoint to provide application-driven point-in-time copies. AppSync simplifies and automates the process of generating and consuming copies of production data. Integrated with EMC storage arrays, AppSync enables application owners to satisfy copy demand for data repurposing, operational recovery, and disaster recovery1.

AppSync allows users to:

Discover application databases or file systems.

Create copies of the data (snapshots, clones, or replicas) that are application-consistent.

Use the copies for various purposes, such as development/testing, reporting, or backup and recovery operations.

Restore from the copies in case of data loss or corruption.

AppSync's integration with RecoverPoint enhances its capabilities by providing a robust data protection solution that can create point-in-time copies based on specific application events or schedules, ensuring that copies are consistent with the application's state at that moment1.
