What is the recommended wait period before running the Balance Load tool?
C
Explanation:
The Dell RecoverPoint documentation recommends a wait period of 7 days before running the
Balance Load tool. This period allows for the system to stabilize and for any anomalies in the load
distribution to become apparent, ensuring that the Balance Load tool can operate effectively. It’s
important to note that this information is based on the best practices outlined in the Dell
RecoverPoint documentation and may be subject to change with different versions or specific system
configurations.

Which parameter is used as the Locking ID for a RecoverPoint/EX license?
C
Explanation:
The Locking ID for a RecoverPoint/EX license is typically associated with a unique identifier of the
RecoverPoint system itself. This ID ensures that the license is applied to the correct system and is not
interchangeable with other systems or components.
The RecoverPoint System ID serves as this
unique identifier, which is used to lock the license to a specific RecoverPoint installation1
.
It’s important to note that licensing information can be complex and may vary depending on the
specific configuration and version of the RecoverPoint system.

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
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 storage arrays.
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.

RecoverPoint documentation or contact Dell EMC support directly.
What describes RecoverPoint asynchronous replication write operations to the Journal volumes?
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
.
During the Write phase of RecoverPoint replication, when does the write splitter send an
acknowledgement back to the host that initiated the write?
B
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.
Reference:
According to the Dell RecoverPoint for Virtual Machines 6.0.1 vSphere HTML5 Plugin Administrator's
Guide:
"The write splitter sends an acknowledgement to the host after it receives an acknowledgement
from the production LUN" (vrpa.pdf, p.17).
"Ensuring that the write is committed to the production LUN before sending an acknowledgement to
the host guarantees data integrity and consistency" (vrpa.pdf, p.18).
An application protected by RecoverPoint has spanned onto a second XtremlO system. How can this
application continue to be protected by RecoverPoint?
D
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
.
In a RecoverPoint environment, which EMC array supports Snap-based replication?
C
Explanation:
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
.

After creating a Consistency Group with a local copy, initialization is taking longer than expected.
What is a possible reason for this condition?
A
Explanation:
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
.
Where are incoming writes sent to during the Write phase of the RecoverPoint workflow?
D
Explanation:
1.The production host writes data to the production volumes, but is first intercepted by the splitter.
The splitter sends the write data to the RPA.
2.Immediately upon receipt of the write data, the local RPA returns an acknowledgement (ACK) to
the splitter.
3.The splitter then writes the data to the production storage volume.
4.The storage system returns an ACK to the splitter upon successfully writing the data to storage.
5.The splitter sends an ACK to the host that the write has been completed successfully
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?
B
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
.

A storage administrator wants to protect their distributed VPLEX volumes using the RecoverPoint,
MetroPoint feature. The administrator wants to know if they need to be aware
of any special considerations. What information should be provided to the administrator?
B
Explanation:
When using the MetroPoint feature of RecoverPoint to protect distributed VPLEX volumes, it is
essential that both VPLEX clusters have a connected RecoverPoint cluster.
This is necessary to create
a MetroPoint Consistency Group, which is a configuration that allows for continuous data protection
and availability across multiple sites1
.
The MetroPoint solution provides a three-site configuration that combines VPLEX Metro (which
operates within distances of 5-10ms round-trip time, application dependent) with a third site
provided by a RecoverPoint appliance.
This setup ensures that data is continuously available and
protected, and it allows for failover between two Metro sites without impacting protection1
.
It’s important to note that while MetroPoint enables protection for VPLEX devices at both sites, the
requirement for both VPLEX clusters to be connected to a RecoverPoint cluster is crucial for the
creation and proper functioning of a MetroPoint Consistency Group1
.

Which factor affects the time it takes a Consistency Group to complete the first-time initialization?
B
Explanation:
The performance of the Journal volumes at the remote copy can significantly affect the time it takes
for a Consistency Group to complete the first-time initialization. The Journal volumes are where all
the changes to the protected volumes are recorded before they are replicated to the remote site.
If
the Journal volumes are performing poorly, due to issues like high latency or low IOPS (Input/Output
Operations Per Second), it can slow down the initialization process as the system struggles to record
and replicate the data efficiently1
.
Other factors such as the distance between the production and remote copy clusters and the number
of RecoverPoint Appliances (RPAs) at both the production and remote copy clusters can also
influence the initialization time. However, these factors typically affect the ongoing replication
performance rather than the initial synchronization.
The number of RPAs can impact the system’s
ability to process and replicate data, but the most direct impact on initialization time is the
performance of the Journal volumes, as they are the bottleneck in the data recording process1
.
