Dell EMC D-RP-OE-A-24 Dell RecoverPoint Operate Achievement Exam Practice Test

Answer : B

The get_system_status command in the RecoverPoint CLI is used to provide a summary of the system's health, including any errors and warnings. This command can be executed to check the status of one site or the entire RecoverPoint system. The output includes information about the RecoverPoint Appliances (RPAs), Consistency Groups, and any issues that may need attention.

The process for using this command is as follows:

Access the CLI: Log into the RecoverPoint CLI using appropriate credentials.

Run the Command: Execute the get_system_status command to retrieve the system status.

Review the Summary: The command output will display a summarization of the system's health, including errors and warnings.

Take Action: Based on the summary, the administrator can take necessary actions to address any reported issues.

This command is a useful tool for administrators to quickly assess the state of the RecoverPoint environment and ensure that it is functioning correctly1.

Answer : C

The Journal lag in a Dell RecoverPoint system refers to the amount of data that has been written to the production volumes but has not yet been replicated to the remote site or copy volumes. The maximum Journal lag setting affects the RPO because it determines the maximum allowable time or data volume that can pass before the data must be replicated to the remote site to meet the recovery objectives.

Here's how the Journal lag impacts the RPO:

Journal Lag Definition: Journal lag is the measure of the difference between the most recent write to the production volume and what has been replicated to the copy volume.

RPO Impact: The RPO is the maximum targeted period in which data might be lost from an IT service due to a major incident. If the Journal lag exceeds the maximum setting, it means that the RPO could be breached, as there would be more data at risk of being lost than what is acceptable per the RPO policy.

Management Actions: Administrators can monitor and manage the Journal lag to ensure that the RPO is maintained. If the lag approaches the maximum setting, actions may be taken to increase replication throughput or address any issues causing replication delays.

In summary, the maximum Journal lag setting is crucial for ensuring that the RPO is met, as it directly influences the amount of data that could be lost in the event of a failure or disaster1.

Answer : C

When setting up replication for a Consistency Group between clusters using XtremIO storage arrays at each site connected through Fibre Channel, the maximum throughput that can be expected per RecoverPoint Appliance (RPA) is 300 MB/s. This throughput is a measure of how much data can be transferred from one site to another per second by each RPA involved in the replication process.

The throughput capacity is important for planning and ensuring that the RecoverPoint system can handle the expected data load during replication activities. It affects the Recovery Point Objective (RPO) and the overall efficiency of the disaster recovery setup. The 300 MB/s figure provides a benchmark for administrators to gauge the performance capabilities of their RecoverPoint system when used in conjunction with XtremIO storage arrays1.

It's important to note that actual throughput can vary based on several factors, including network conditions, the amount of data being replicated, and the specific configuration of the RecoverPoint and XtremIO systems1.

Answer : C

When using the automatic journal provisioning feature in RecoverPoint, the system requires dedicated resource pools to be set up. These resource pools are predefined storage resources that RecoverPoint can utilize to automatically create and allocate Journal volumes as needed when adding a Consistency Group1.

The process for setting up automatic journal provisioning typically involves:

Creating Resource Pools: The administrator defines resource pools within the storage array, dedicating specific storage resources for RecoverPoint's use.

Configuring RecoverPoint: Within the RecoverPoint configuration, the administrator specifies that these resource pools are to be used for automatic journal provisioning.

Adding a Consistency Group: When a new Consistency Group is added, RecoverPoint automatically provisions Journal volumes from the dedicated resource pools without manual intervention by the administrator.

Monitoring and Managing Journals: The administrator can monitor the automatically provisioned Journals and manage them as necessary through the RecoverPoint management interface.

This feature streamlines the process of setting up and managing Journal volumes, making it more efficient and less prone to human error1.

Answer : A

To reduce the impact of the initial volume synchronization on production applications in a Dell RecoverPoint system, the config_link_policy command can be used with the regulate_application=yes parameter. This command configures the link policy for a Consistency Group and allows for the regulation of I/O to minimize the impact on production applications during synchronization1.

The process involves:

Identifying the Consistency Group: Determine the name of the Consistency Group that contains the production volume you wish to regulate.

Running the command: Execute the config_link_policy command with the appropriate parameters, including the Consistency Group name and the copies involved.

Setting regulate_application=yes: This parameter tells the system to regulate the application I/O, which helps to manage the load on production applications during the initial synchronization.

Monitoring the impact: After applying the command, monitor the production applications to ensure that the impact of the synchronization is minimized as intended.

This command is part of the RecoverPoint CLI and is used to manage the performance impact of replication activities on production environments1.

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.
