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 : A

When initializing a Consistency Group with a local copy in a RecoverPoint environment, several factors can affect the duration of the process. One possible reason for a longer than expected initialization time is slow performing storage on the production array. If the production storage is not able to handle the I/O operations efficiently, it can lead to delays in the initialization process1.

Another factor to consider is the available bandwidth to the RecoverPoint Appliances (RPAs). Limited WAN bandwidth can also cause delays, but since the scenario mentions a local copy, WAN bandwidth is less likely to be the issue unless the RPAs are also handling remote replication1.

Size mismatch between the production and copy volumes or the copy not being attached to the same splitter as production could also be potential issues, but these would typically prevent initialization from proceeding rather than causing a delay1.

For a detailed diagnosis and resolution, it is recommended to review the system's performance metrics and logs, and consult the official Dell RecoverPoint documentation or contact Dell EMC support directly1.

Answer : C

In a Dell EMC RecoverPoint environment, Snap-based replication is supported by the Unity array. This feature leverages the intelligent array-based snapshot capability available in Dell EMC Unity platforms. It enhances asynchronous replication by allowing a user-defined interval for replication, which is particularly useful for environments where minimizing the replication window is critical1.

The Snap and Replicate feature is enabled by leveraging the intelligent array-based snapshot capability available in Dell EMC VNX, XtremIO, and VMAX3/AF platforms as well1. However, for the specific context of the question, which focuses on the EMC array that supports Snap-based replication in a RecoverPoint environment, the correct answer is Unity2.

For the most accurate and up-to-date information, it is always best to consult the latest official Dell RecoverPoint documentation or contact Dell EMC support directly3.
