Curious about Actual Dell EMC RecoverPoint Operate (D-RP-OE-A-24) Exam Questions?

Correct : C

When a Consistency Group failover is performed to a remote copy in a Dell RecoverPoint system, the point-in-time images stored in the copy Journal are deleted after the copy becomes the new production. This is because the copy Journal's role is to maintain a record of changes for recovery purposes, and once the copy is promoted to production, its Journal is reset to start recording new changes from that point forward1.

The process involves the following steps:

Failover Initiated: The administrator initiates a failover to the remote copy.

Copy Becomes Production: The remote copy is promoted to the production role.

Journal Reset: The point-in-time images in the copy Journal are deleted as part of the promotion process.

New Production Journal: A new production Journal is started to record changes from the new production copy moving forward.

This ensures that the RecoverPoint system can continue to protect the data with a fresh start for the new production environment1.

Correct : C

In Dell RecoverPoint, a Bookmark is a user-created point-in-time image that can be tied to specific application events. This feature allows users to mark a particular point in time within the continuous data protection timeline of RecoverPoint, which can be used for recovery purposes. Here's how it works:

User Command: A user issues a command to create a Bookmark, typically through the RecoverPoint management interface or via scripting.

Tied to Application Events: The Bookmark can be associated with specific application events, such as before and after a significant update or batch process.

Point-in-Time Image: The Bookmark represents a point-in-time image of the data at the moment the Bookmark was created.

Recovery: In the event of data corruption or loss, the Bookmark can be used to recover data to the exact state it was in at the time of the Bookmark.

Bookmarks are an integral part of RecoverPoint's data protection capabilities, providing flexibility and precision for data recovery operations1.

Correct : D

In a Dell RecoverPoint environment, Journal volumes are critical components used to track and manage point-in-time images for data replication and recovery. If Journal volumes are mistakenly masked to hosts, the following occurs:

Hosts Gain Access: The hosts that are zoned/masked to the Journal volumes gain the ability to write to these volumes.

Potential for Corruption: Any write access by hosts to the Journal volumes can lead to corruption of the Journal. This is because Journals are meant to be managed exclusively by RecoverPoint and should not be directly accessed or modified by hosts.

Impact on Replication: Journal corruption can disrupt the RecoverPoint replication process, potentially leading to data loss or an inability to recover to specific points in time.

Resolution: To prevent such issues, it is crucial to ensure that Journal volumes are not exposed to hosts and are only accessed by RecoverPoint Appliances (RPAs) for replication purposes12.

It is important to follow best practices for zoning and masking in a storage environment to avoid such critical configuration errors12.

Correct : C

RecoverPoint and VMAX Connectivity:

A physical RecoverPoint cluster connected to a VMAX array uses Fibre Channel connections for communication. Each RPA typically has two Fibre Channel ports.

WWPN (World Wide Port Name):

WWPNs are unique identifiers assigned to each port in a Fibre Channel network, including both RecoverPoint and VMAX ports.

Minimum Number of WWPNs:

For a single RecoverPoint appliance (RPA), the minimum number of ports includes:

2 RecoverPoint Ports (RP Ports): Each RPA usually has at least two Fibre Channel ports for redundancy.

1 Front-End Adapter (FA) Port: The VMAX array has at least one FA port connected to the RecoverPoint system.

Diagnostic Tests:

When running SAN diagnostics from the boxmgmt menu, the test will show the WWPNs of all connected ports, including both the RPA ports and the VMAX FA ports.

From the Dell RecoverPoint for Virtual Machines 6.0.1 documentation and standard SAN configuration principles:

'Each RecoverPoint appliance typically connects to the storage array using two Fibre Channel ports' (general SAN configuration best practices).

'The VMAX array will have at least one FA port connected to the RecoverPoint system for data transfer and replication purposes.'

Therefore, when running SAN diagnostics from the boxmgmt menu, the minimum number of WWPNs that can be seen in the storage ports section of the diagnostic test is 3 (2 RPA ports + 1 FA port).

Correct : D

When the ''Test a Copy'' wizard is in progress in a Dell RecoverPoint environment, it temporarily disconnects the local copy from the production and remote copies to allow testing of the data at a specific point in time without affecting the ongoing replication and production operations. The steps involved are:

Initiate Test a Copy: The administrator starts the ''Test a Copy'' wizard from the RecoverPoint management interface.

Disconnect Local Copy: The wizard disconnects the local copy from the production and remote copies to isolate it for testing.

Perform Testing: The administrator or users perform necessary tests on the local copy, which is now in an isolated state.

Reconnect Local Copy: Once testing is complete, the wizard will reconnect the local copy to resume normal replication and protection operations.

This process ensures that testing can be conducted on a consistent dataset without impacting the production environment or replication processes1.
