NEW QUESTION # 14
Why is Image Access instantaneous when testing a copy with XtremlO arrays?
- A. No rolling forward or backward of the Journal is required
- B. RecoverPoint uses XtremIO synchronous Snap-based replication
- C. XtremlO completes the copy "roll back" as a background task
- D. RecoverPoint performs initialization based on the DIFF result
Answer: A
Explanation:
When using XtremIO arrays with RecoverPoint, Image Access is instantaneous because there is no need to roll the Journal forward or backward. This is due to the way XtremIO handles snapshots, which are used by RecoverPoint during the Image Access process:
* Snapshot Creation: XtremIO creates snapshots very efficiently, without the need for a full copy of the data. These snapshots are pointer-based, meaning they reference the original data without duplicating it.
* Instant Access: When Image Access is initiated, RecoverPoint can immediately present a snapshot to the host because it's simply a matter of accessing the pointers to the existing data, rather than having to roll data forward or backward in the Journal.
* Continuous Replication: Even while Image Access is in use, replication and distribution continue unaffected, ensuring that protection of the production data is maintained1.
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 purposes1.
NEW QUESTION # 15
Which attributes can affect the Distribution phase of Consistency Groups?
- A. Compression and deduplication settings of the Consistency Group
- B. Journal volume performance, storage array performance, and copy volume performance
- C. Copy location, WAN bandwidth, and replication type
- D. Change rate of the applications and number of replication sets
Answer: D
Explanation:
The Distribution phase of Consistency Groups in a Dell RecoverPoint environment is influenced by several factors:
* Change Rate of Applications: The amount of data change occurring in the applications being protected can affect how quickly the data needs to be distributed.
* Number of Replication Sets: More replication sets can increase the complexity and load on the system during the Distribution phase.
* Copy Location: The geographical location of the copy in relation to the production site can impact latency and distribution times.
* WAN Bandwidth: Available bandwidth of the WAN connection between sites is crucial for timely data distribution.
* Replication Type: Whether the replication is synchronous or asynchronous can affect the Distribution phase.
* Compression and Deduplication Settings: These settings can optimize data transfer but also require processing that can impact distribution.
* Journal Volume Performance: The speed at which the Journal can record and distribute data is vital for the Distribution phase.
* Storage Array Performance: The overall performance of the storage array will influence how quickly data can be distributed.
* Copy Volume Performance: The performance of the copy volume can affect how quickly it can receive and integrate the distributed data.
Understanding and optimizing these attributes can help ensure efficient operation of the RecoverPoint system during the Distribution phase1.
NEW QUESTION # 16
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 # 17

What should be done to allow testing to continue without disruption to their testing?
- A. Navigate to Protection > Manage Protection > Select the CG from the list and select the copy.
Click Edit Journal, and add one or more additional Journal volumes. - B. Navigate to Protection > Manage Protection > Select the CG from the list and select the copy.
Click Edit, and then increase the reserved image access percentage from 20% - C. Use the config_copy_group= copy= policy image_access_log_size= CLI command
- D. Expand the Journal volume using native array tools.
Navigate to Protection > Manage Protection > Select the CG from the list and select the copy.
Click Edit Journal, and then select "Expand Journal".
Answer: A
Explanation:
When the database team's write activity is expected to exceed the space allocated for Image Access mode in RecoverPoint, additional Journal volumes need to be added to accommodate the increased write activity. This can be done through the Unisphere for RecoverPoint interface:
* Navigate to Protection: Access the Protection menu in the Unisphere for RecoverPoint.
* Manage Protection: Go to the Manage Protection section.
* Select the Consistency Group (CG): Choose the appropriate CG from the list.
* Select the Copy: Click on the copy that is being used for the Point-in-Time (PIT) testing.
* Edit Journal: Click on the Edit Journal option.
* Add Journal Volumes: Add one or more additional Journal volumes to ensure there is enough space for the write activity during the testing periD.
By adding additional Journal volumes, the database team can continue their testing without disruption due to space limitations in the Image Access mode1.

NEW QUESTION # 20
In order to balance the workload of a RecoverPoint system, an administrator decided to change the primary RPA for specific Consistency Groups. Where is this setting configured?
- A. Copy Policy tab for the remote copy
- B. Group Policy tab for the Consistency Groups
- C. Copy Policy tab for the production copy
- D. Link Policy tab for the Consistency Groups
Answer: B
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.
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. 0
- B. 1
- C. Determined by the number of copies
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 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. Upgrade the RecoverPoint with VNX(SE) license to RecoverPoint/EX and then reconfigure the Consistency Group
- B. Add a copy into the existing Consistency Group for a local replication
- 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: B
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.

NEW QUESTION # 26
When using a Distributed Consistency Group, additional traffic is generated between the primary RPA and secondary RPAs. Where is this increase in traffic observed?
- A. Additional traffic is seen on the management network between the RPAs
- B. Additional traffic is seen on the FC links between the RPAs
- C. Additional traffic is seen on the WAN network between the RPAs
- D. No additional traffic will be observed because host writes are multicast to all appliances in a cluster
Answer: C
Explanation:
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.
NEW QUESTION # 27
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

Answer: A
NEW QUESTION # 28
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. RecoverPoint system needs to be converted to a RP/EX system to support the extra volumes
- B. Addition of the local volumes will exceed the 16K volume limit per cluster
- C. Consistency Group copy cannot have 1024 volumes within the copy
- D. Cluster has the maximum number of RPAs and cannot be expanded
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.
