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

Answer : A

Answer : A

When using the CLI to create a new Consistency Group in RecoverPoint, after initiating the process with the create_group command, the next step involves adding volumes to the group. The add_replication_volume command is used to add a volume to a Consistency Group as a replication volume. This command specifies the volume to be replicated and associates it with the newly created group1.

The sequence of commands would typically follow this pattern:

Run create_group to initiate the creation of a new Consistency Group.

Run add_replication_volume to add each production volume that needs to be replicated within the Consistency Group.

Additional commands would follow to configure the properties of the Consistency Group and its replication sets1.

It's important to note that the add_group_set command is used for different purposes, such as grouping multiple Consistency Groups together, and the create_replication_volume and create_production_copy commands are not standard commands in the RecoverPoint CLI for this context1.

Answer : B

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.

Answer : C

Answer : B

When creating a Consistency Group using Unisphere on RecoverPoint/EX, the wizard displays volumes for selection as copy volumes based on specific criteria. The volumes displayed must be masked to the selected cluster and must be the same size or larger than the production volume. This ensures that the copy volume has sufficient capacity to hold all the data from the production volume and any additional data that may be replicated in the future.

The process for selecting the copy volume involves:

Identifying all volumes visible to the selected cluster.

Filtering out volumes that are smaller than the production volume to prevent potential space issues.

Presenting the remaining volumes as options for the administrator to choose as the copy volume.

This approach prevents the accidental selection of a volume that is too small to serve as a copy volume, which could lead to replication issues or data loss. It also allows for flexibility in choosing a larger volume if desired, which can be beneficial in scenarios where future growth is anticipated1.

Answer : C

The setting to change the primary RecoverPoint Appliance (RPA) for specific Consistency Groups is configured under the Group Policy tab for the Consistency Groups. This tab allows administrators to manage and adjust policies that affect the entire Consistency Group, including the assignment of the primary RPA, which is responsible for managing the replication for the group1.

The process for changing the primary RPA typically involves:

Accessing the Unisphere for RecoverPoint interface.

Navigating to the Consistency Groups section.

Selecting the specific Consistency Group to be modified.

Going to the Group Policy tab.

Adjusting the settings to designate a new primary RPA for the group.

This change can help balance the workload across the RPAs in the RecoverPoint system, ensuring that no single RPA becomes a performance bottleneck and that the replication process remains efficient and effective1.

Answer : A

The save_settings command in Dell RecoverPoint is used to commit cluster configuration changes to the repository volume. When changes are made to the RecoverPoint cluster configuration, they need to be saved to ensure that they persist across system reboots and are recognized by all nodes in the cluster. The repository volume serves as a centralized storage location for these configurations1.

The process of using the save_settings command is as follows:

After making configuration changes to the RecoverPoint cluster, the administrator issues the save_settings command.

The command commits the changes to the repository volume, which is a dedicated space on the storage array for storing system settings.

This ensures that the configuration changes are preserved and can be accessed by the RecoverPoint Appliances (RPAs) when needed1.

It's important to note that the save_settings command does not create a script file for later use, nor does it modify the configuration backup interval. Its primary function is to ensure that any changes made to the cluster configuration are saved and applied correctly1.
