NEW QUESTION # 15
A RecoverPoint system has been deployed with XtremlO at production and disaster recovery sites. What is an accurate statement, if the replication mode for a Consistency Group has been set as "Continuous"?
- A. Set customized time between cycles
- B. Effective RPO can be < 60 seconds
- C. Set minimum time between cycles
- D. Effective RPO will be 0 seconds
Answer: B
Explanation:
In a Dell RecoverPoint system with XtremIO arrays at both production and disaster recovery sites, setting the replication mode for a Consistency Group as "Continuous" implies that the replication occurs continuously without predefined intervals. This mode aims to minimize the Recovery Point Objective (RPO), which is the maximum targeted period in which data might be lost due to a major incident. While an RPO of 0 seconds is ideal, it is often not practical due to network latency and system processing times.Therefore, an effective RPO of less than 60 seconds is a realistic target for a
"Continuous" replication mode, ensuring that data loss is minimized to the lowest possible timeframe in the event of a disaster1.
NEW QUESTION # 16
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 Distribution phase has completed
- B. After the splitter has received an acknowledgement from the RPAs
- 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 # 21
A RecoverPoint storage administrator needs to protect a mission critical application. The application is stored on three volumes provisioned from a new VNX. Once the Consistency Group is created for the application, how many replication sets will the group contain?
- A. Determined by the number of copies
- B. 0
- C. 1
Answer: B
Explanation:
In Dell RecoverPoint, a Consistency Group is built from one or more replication sets.Each replication set consists of a production volume plus any local or remote copy volumes to which it is replicating1. Since the mission-critical application is stored on three volumes, and each volume will be part of a replication set, the Consistency Group for the application will contain three replication sets.This ensures that all three volumes are protected and replicated as part of the RecoverPoint protection strategy1.
It's important to note that the number of replication sets in a Consistency Group is equal to the number of production volumes being replicated.Therefore, if an application spans multiple volumes, each volume will be part of its own replication set within the Consistency Group1.
NEW QUESTION # 22
A storage administrator has created a new Consistency Group with a remote copy. After enabling the new group, the administrator notices several other Consistency Groups are experiencing high load alerts.
What is possible cause for the high load conditions?
- A. Initialization is consuming all the WAN bandwidth
- B. Journal pool for the new Consistency Group is undersized
- C. Journal pool for the new Consistency Group has poor performing storage
- D. Not enough licensed replication storage is available for the new Consistency Group
Answer: A
NEW QUESTION # 23
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. Commit cluster configuration changes to the repository volume
- D. Modify or configure the RecoverPoint configuration backup interval
Answer: C
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 # 24
A company is using XtremlO for their RecoverPoint environment. They have approximately 100 GB of cumulative changes per day with the change being constant throughout the day. The company has a requirement to roll back 48 hours.
How should the Journals be sized and how should the copy policy be configured to ensure maximum protection with the least amount of storage used?
- A. 200 GB with the "Required Protection Window" set for Default
- B. 10 GB with the "Required Protection Window" set for 2 days
- C. 40 GB with the "Required Protection Window" set for 2 days
- D. 5 GB with the "Required Protection Window" set for 2 days
Answer: A
Explanation:
* Calculate Daily Changes: With 100 GB of cumulative changes per day, the total amount of changes over two days would be 200 GB.
* Determine Journal Size: The Journal size must be large enough to store all the changes for the required rollback periD.Therefore, a Journal size of 200 GB is necessary.
* Set Protection Window: The "Required Protection Window" should be set for 2 days to match the rollback requirement.
* Configure Copy Policy: The copy policy should be configured to ensure that the Journal maintains the point-in-time images for at least 48 hours.
By following these steps, the company can ensure maximum protection with the least amount of storage used, while also meeting their rollback requirements1234.

* 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 # 29
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. RecoverPoint with VNX(SE) does not support more than two copies in a single Consistency Group
- B. Delete and reconfigure the existing Consistency Group for a local and remote replication
- C. Upgrade the RecoverPoint with VNX(SE) license to RecoverPoint/EX and then reconfigure the Consistency Group
- D. Add a copy into the existing Consistency Group for a local replication
Answer: D
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 # 30
A RecoverPoint administrator wants to use the compression setting to save bandwidth in their environment.
What will be the impact of changing the link compression setting on aConsistency Group?
- A. Long resynchronization
- B. Temporary high-load
- C. Journal history will be lost
Answer: C
Explanation:
Changing the link compression setting on a RecoverPoint Consistency Group can result in a temporary high-load on the system. This is because when compression is enabled or settings are changed, the system needs to compress the existing data before it can be transmitted, which requires additional processing power and can temporarily increase the load on the RecoverPoint Appliances (RPAs).
The process involves:
* The administrator changes the link compression setting in the Consistency Group configuration.
* The RPAs begin compressing the data that needs to be replicated across the network.
* This compression process increases the CPU and memory usage on the RPAs, leading to a temporary high-load situation.
* Once the initial compression is completed, the system load returns to normal levels, and replication continues with the new compression setting in effect.
It's important to note that while the system is under high-load, there might be a temporary impact on performance, but this does not affect the integrity of the replication or the Journal history.The system is designed to handle such temporary increases in load without losing any critical data1.
NEW QUESTION # 31
Which RecoverPoint CLI command can be used to show a summarization of the errors and warnings for either one site or the entire RecoverPoint system?
- A. get_system_status
- B. get_clusters_topology
- C. get_events_log
- D. get_rpa_states
Answer: A
NEW QUESTION # 32
When attempting to protect new XtremlO LUNs, the administrator is unable to add an XtremIO source LUN to the Consistency Group. What is a possible reason for this issue?
- A. XtremlO arrays are only protected with RecoverPoint for VMs
- B. XtremIO LUN was created with a 512-byte block size
- C. RecoverPoint/EX only allows the protection of VNX arrays
- D. XtremlO array was not licensed in RecoverPoint
Answer: D
Explanation:
One possible reason for the inability to add an XtremIO source LUN to the Consistency Group in RecoverPoint could be that the XtremIO array was not licensed in RecoverPoint. Licensing is a critical step in enabling the features and functionalities of RecoverPoint for specific storagearrays.If the XtremIO array is not licensed, RecoverPoint would not recognize or allow the addition of its LUNs to a Consistency Group1.
Additionally, it's important to ensure that the RecoverPoint version supports the XtremIO array model.For instance, RecoverPoint does not support XtremIO X2 arrays until version 5.11. Therefore, if the RecoverPoint version is earlier than 5.1, it would not be able to replicate volumes from an XtremIO X2 array, which could manifest as an issue when trying to add LUNs to a Consistency Group.
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 directly.
NEW QUESTION # 33
An application protected by RecoverPoint has spanned onto a second XtremlO system. How can this application continue to be protected by RecoverPoint?
- A. Reconfigure the existing Consistency Group to be a Distributed Consistency Group
- B. Create another Consistency Group and define group sets with periodic parallel bookmarks
- C. Encapsulate the application volumes using VPLEX and use the VPLEX splitter
- D. Extend the existing Consistency Group onto the second XtremIO system
Answer: A
Explanation:
When an application protected by RecoverPoint spans onto a second XtremIO system, it is necessary to ensure that the protection extends across both systems. The appropriate action in this scenario is to reconfigure the existing Consistency Group to be a Distributed Consistency Group.This allows for the inclusion of multiple storage systems under the same protection umbrella, ensuring that all parts of the application, even those that span multiple systems, are consistently protected1.
A Distributed Consistency Group in RecoverPoint is designed to maintain synchronous or asynchronous replication across different arrays, which may be geographically dispersed.This ensures that write operations are captured and replicated in a manner that maintains the consistency of the application data, regardless of the underlying storage system1.
For detailed guidance on configuring Distributed Consistency Groups and extending protection to additional storage systems, it is recommended to refer to the official Dell RecoverPoint documentation or contact Dell EMC support for assistance tailored to the specific configuration and version of the RecoverPoint system being used1.
NEW QUESTION # 34
A RecoverPoint administrator is using the CLI to create a new Consistency Group. After beginning the process by running the command create_group, what is the next command that needs to be run?
- A. create_production_copy
- B. create_replication_volume
- C. add_replication_volume
- D. add_group_set
Answer: C
Explanation:
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.
NEW QUESTION # 35
Which RPA type(s) connect to protected storage using iSCSI?
- A. Gen-6 only
- B. vRPA only
- C. Gen-5 and Gen-6
- D. Gen-6 and vRPA
Answer: B
Explanation:
In Dell EMC RecoverPoint, virtual RPAs (vRPAs) use iSCSI protocol for connections. This is because vRPAs are designed to operate in virtual environments where iSCSI is commonly used for storage networking due to its ability to work over standard IP networks.Physical RPAs, such as Gen-5 and Gen-6, typically use Fibre Channel (FC) for direct storage connectivity1.
Here's a breakdown of the connectivity:
* vRPA: Utilizes iSCSI for connections to protected storage. This is suitable for virtualized environments where the RecoverPoint for Virtual Machines (RP4VMs) operates.
* Gen-5 and Gen-6 RPAs: These are physical appliances that generally use Fibre Channel for connectivity, which is more common in physical data center environments where dedicated storage networks are present1.
It's important to choose the correct RPA type based on the storage infrastructure and connectivity requirements of the environment1.
