NEW QUESTION # 34
During the Write phase of RecoverPoint replication, when does the write splitter send an acknowledgement back to the host that initiated the write?
- A. After the splitter has received an acknowledgement from the RPAs
- B. After the Distribution phase has completed
- C. After the splitter has received an acknowledgement from the production LUN
- D. As soon as the splitter receives the write
Answer: C
Explanation:
* RecoverPoint Write Phase:
* In the RecoverPoint replication process, the write splitter plays a crucial role in intercepting writes from the host and forwarding them to both the production storage and the RecoverPoint appliances (RPAs).
* Write Splitter Functionality:
* The write splitter intercepts write I/O requests from the host and splits the I/O to both the production LUN and the RPAs. This ensures that the data is written to both the primary storage and replicated copies.
* Acknowledgement Process:
* During the write phase, the write splitter must ensure that the data is successfully written to the production LUN before acknowledging the write request back to the host.
* This is because the primary concern is ensuring data integrity and confirming that the data is safely stored in the production environment before any replication considerations.
* Detailed Workflow:
* Step 1: Host issues a write request.
* Step 2: The write splitter intercepts the write request.
* Step 3: The write splitter forwards the write to the production LUN and the RPAs.
* Step 4: The production LUN processes the write and sends an acknowledgement back to the write splitter.
* Step 5: Upon receiving the acknowledgement from the production LUN, the write splitter then sends an acknowledgement back to the host.
NEW QUESTION # 35
A storage administrator has one production site and one remote site. The administrator configured the RecoverPoint with VNX(SE) cluster at both sites. The current environment has two Consistency Groups configured with two copies each; one production copy and one remote copy.
Based on the company's growing business requirements, the
administrator has been asked to keep a local copy of the production data.
Which action should occur in order to meet this requirement?
- A. Add a copy into the existing Consistency Group for a local replication
- B. Upgrade the RecoverPoint with VNX(SE) license to RecoverPoint/EX and then reconfigure the Consistency Group
- C. RecoverPoint with VNX(SE) does not support more than two copies in a single Consistency Group
- D. Delete and reconfigure the existing Consistency Group for a local and remote replication
Answer: A
Explanation:
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.
NEW QUESTION # 36

- B. Click on Admin > System Analysis Tools > RPAs
- C. Click on Protection > Cluster name > RPA details
- D. Click on Dashboard > RPAs > RPA type
Answer: A
Explanation:
To identify whether physical or virtual RPAs are in use on a specific cluster using Unisphere for RecoverPoint, follow these steps:
* Navigate to RPA Clusters: In Unisphere, locate and click on the 'RPA clusters' section.
* Select Cluster Name: Find and select the specific cluster you want to investigate.
* View RPA Details: Click on the 'RPAs' option to view detailed information about the RPAs associated with the selected cluster.
This process will provide you with the necessary information to determine the type of RPAs (physical or virtual) that are being used within the specified cluster1.
NEW QUESTION # 38
A RecoverPoint administrator needs to add a local copy to three existing Consistency Groups. The RecoverPoint system currently contains 100 Consistency Groups. Each group has one remote copy with 80 replication sets. Each cluster contains eight physical RPAs.
However, the administrator is unable to add all the local copies. What is a cause for this issue?
- A. Consistency Group copy cannot have 1024 volumes within the copy
- B. Addition of the local volumes will exceed the 16K volume limit per cluster
- C. Cluster has the maximum number of RPAs and cannot be expanded
- D. RecoverPoint system needs to be converted to a RP/EX system to support the extra volumes
Answer: B
Explanation:
In a Dell RecoverPoint system, there is a limit to the number of volumes that can be managed within a cluster.If an administrator attempts to add local copies to existing Consistency Groups and the system already contains a significant number of Consistency Groups and replication sets, it is possible that adding more local volumes would exceed the system's volume limit, which is 16,000 volumes per cluster1.
Here's how the volume count could exceed the limit:
* Each of the 100 Consistency Groups has 80 replication sets.
* Assuming each replication set consists of at least one volume, this would already account for 8,000 volumes (100 CGs x 80 volumes each).
* Adding a local copy for each Consistency Group would double the number of volumes, potentially exceeding the 16K volume limit per cluster.
This limitation is in place to ensure system stability and performance.If the limit is exceeded, the administrator will not be able to add additional local copies until the volume count is reduced or the system is reconfigured to stay within the limit1.
NEW QUESTION # 39
A storage administrator is unable to perform Direct Access to a copy in their RecoverPoint environment.
Which array type has this limitation with regards to RecoverPoint copies?
- A. VNX
- B. VMAX
- C. XtremIO
- D. VPLEX
Answer: C
Explanation:
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.
NEW QUESTION # 40
After a logical corruption, data on a production volume is inaccessible. As the volume is replicated using RecoverPoint, the administrator decides to use the "Test a Copy and Recover Production" wizard to restore this volume to its state prior to the logical corruption.
What is the correct sequence of steps to complete the recovery activity?
Answer:
Explanation:
Explanation:
A screenshot of a recovery program Description automatically generated with medium confidence
To recover a production volume that has become inaccessible due to logical corruption using RecoverPoint's
"Test a Copy and Recover Production" wizard, follow these steps:
* Select a snapshot prior to the corruption: Identify and choose the appropriate point-in-time image from the Journal that was taken before the corruption occurred.
* Mount the snapshot to a verification host and verify its integrity: Attach the selected snapshot to a non-production host where you can perform checks to ensure the data is consistent and free from corruption.
* Unmount the production volume as the Recovery wizard will overwrite it with the recovery data:
Ensure that the current production volume is not in use because the recovery process will overwrite the existing data with the data from the snapshot.
* Monitor the progress of recovery from the Unisphere 'Manage Recovery' wizard: Use Dell EMC's Unisphere interface to track the recovery process and ensure that the data is being restored correctly.
These steps are based on the standard procedures outlined in Dell RecoverPoint documentation for using the "Test a Copy and Recover Production" wizard to restore volumes to a previous state1.
NEW QUESTION # 41
If a VPLEX distributed device is selected during the RecoverPoint Consistency Group Creation wizard, which option will appear?
- A. Section to define production and replica Journals on unregistered storage arrays
- B. Ability to create a MetroPoint Consistency Group
- C. Radio button to select which cluster will be the winning cluster upon the initialization of the Consistency Group
- D. List of LUNs which are less than 10 TBs in size; the size limit for distributed devices
Answer: B
Explanation:
When a VPLEX distributed device is selected during the RecoverPoint Consistency Group Creation wizard, the option to create a MetroPoint Consistency Group becomes available. This is because MetroPoint is a feature that leverages VPLEX distributed devices for enhanced data protection and disaster recovery capabilities. The steps involved in this process typically include:
* Selecting the VPLEX distributed device: During the creation of a Consistency Group, you choose the VPLEX distributed device as the source of replication.
* MetroPoint option appears: Once a VPLEX distributed device is selected, the wizard presents the option to create a MetroPoint Consistency Group.
* Configuring the MetroPoint Consistency Group: If you choose to create a MetroPoint Consistency Group, you will then configure the necessary settings, such as replication mode and RPO (Recovery Point Objective).
* Finalizing the setup: After configuring the settings, you finalize the creation of the Consistency Group, which now has the enhanced capabilities provided by the MetroPoint feature1.
MetroPoint Consistency Groups are designed to provide continuous data protection and availability across multiple sites, combining the benefits of VPLEX Metro with the third-site replication provided by RecoverPoint1.

NEW QUESTION # 43
A RecoverPoint administrator wants to add volumes from an unlicensed array to a RecoverPoint/EX cluster.
Which supported RecoverPoint volume type(s) addresses the
administrator's requirement?
- A. Repository only
- B. Journal only
- C. Repository and Journal
Answer: C
Explanation:
In a RecoverPoint/EX cluster, the administrator can add volumes from an unlicensed array as a repository volume.The repository volume is used for internal RecoverPoint operations, such as storing metadata and system information necessary for the RecoverPoint cluster to function1.
The repository volume does not require a license as it is not part of the data replication path and does not store user data. This allows the administrator to utilize storage from an unlicensed array for this purpose.However, for journal and copy volumes, which are directly involved in data protection and replication, a licensed array is required to ensure proper functionality and support1.
It is important to note that while the repository can be on an unlicensed array, all other volumes involved in replication (such as journal and copy volumes) must be on licensed arrays.This ensures compliance with licensing agreements and enables full support and functionality of the RecoverPoint system1.
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 directly1.
NEW QUESTION # 44
A RecoverPoint administrator performs a Consistency Group failover to a remote copy. What happens to the point-in-time images stored in the copy Journal after the copy becomes production?
- A. Images are replicated to the new copy Journal
- B. Images are deleted
- C. Images are consolidated
- D. Images are replicated to the new production Journal
Answer: B
Explanation:
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.
NEW QUESTION # 45
What describes RecoverPoint asynchronous replication write operations to the Journal volumes?
- A. Volumes of the same capacities will be concatenated and not striped
- B. Writes to the Journal volume are typically large sequential writes
- C. Writes to the Journal volume are typically small sequential writes
- D. Journal is written to at three times the rate of the production volumes
Answer: B
Explanation:
In Dell RecoverPoint, the Journal volumes play a crucial role in asynchronous replication. They store a history of write operations that have occurred on the production volumes, allowing for point-in-time recovery and data rollback. The write operations to the Journal volumes are typically large sequential writes.This is because the Journal is designed to efficiently record and consolidate changes made to the production data, which often involves large blocks of data being written in sequence1.
The Journal's sequential write pattern is optimized for the replication process, ensuring that data is recorded with minimal impact on the production environment.This design choice reflects the need for the Journal to quickly and reliably capture data changes, which can then be replicated to the remote site asynchronously, without requiring immediate acknowledgment from the remote site1.
For detailed information on the configuration and operation of the Journal in a RecoverPoint system, it is recommended to refer to the official Dell RecoverPoint documentation or contact Dell EMC support for guidance specific to your system's configuration and version1.
NEW QUESTION # 46
What is the purpose of the save_settings command?
- A. Preserve the configuration of a RecoverPoint Appliance prior to replacement
- B. Create a script file that can later be used to recreate the system configuration
- C. Modify or configure the RecoverPoint configuration backup interval
- D. Commit cluster configuration changes to the repository volume
Answer: D
Explanation:
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.
NEW QUESTION # 47
When replicating a Consistency Group between clusters using XtremlO at each site that are connected through Fibre Channel, what is the maximum throughput per RPA?
- A. 240 MB/s
- B. 450 MB/s
- C. 300 MB/s
- D. 150 MB/s
Answer: C
Explanation:
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.
NEW QUESTION # 48
A storage administrator is selecting Test a Copy to enable an Image Access for an XtremIO-to-XtremIO Consistency Group. Why is Logged Access the only allowable access mode with this type of replication?
- A. XtremlO snapshots are not host accessible when using RecoverPoint
- B. Direct Access is not possible because the copy cannot be mounted on XtremIO
- C. XtremlO uses snapshots which are instantly promoted as the SCSI personality of the copy
- D. XtremlO cannot process the changes to the Journal required for Virtual Access
Answer: C
Explanation:
* Snapshot Technology: XtremIO arrays use snapshot technology that allows for quick access to data at a specific point in time.
* Logged Access Mode: When using RecoverPoint with XtremIO arrays, Logged Access mode is used because it leverages the snapshot capabilities of XtremIO.
* Instant Promotion: The snapshots created by XtremIO are instantly promoted as the SCSI personality of the copy, making them immediately accessible to the host.
* Efficiency: This process is efficient because it does not require the Journal to roll forward or backward, which would be necessary for other access modes like Virtual Access.
This capability is part of what makes XtremIO an effective storage solution for environments requiring rapid access to multiple data points for testing, development, or recovery purposes12.
NEW QUESTION # 49

- A. detect_bottlenecks
- B. balance_load
- C. get_rpa_statistics
Answer: B
Explanation:
To review the performance data for the past week in a RecoverPoint environment and save the raw data for further analysis, the export_statistics CLI command should be used. This command allows the administrator to export the performance statistics data, which can then be saved to a spreadsheet and used to create graphs or conduct detailed analysis of system performance over time. The steps to use this command are:
* Access the CLI: Log into the RecoverPoint CLI using the appropriate credentials.
* Execute the Command: Run the export_statistics command to gather the performance data.
* Save the Data: The command will generate the performance data, which can be saved to a file.
* Analyze the Data: Open the saved file in a spreadsheet application to review the data and create graphs as needed.
This command is particularly useful for administrators who need to monitor and analyze the performance of their RecoverPoint environment over a specific period1.

- A. Copy Policy tab for the production copy
- B. Copy Policy tab for the remote copy
- C. Group Policy tab for the Consistency Groups
- D. Link Policy tab for the Consistency Groups
Answer: C
Explanation:
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.
