Question 1

An application is running on XtremlO replicating to another XtremlO using RecoverPoint with the
following:
Journal size= 1.05 * (write traffic) * (rollback time in seconds) / (1 - image access log percentage) +
(reserved for marking)
. Average write traffic = 5 Mb/s
. Required rollback time = 24 hours
What is the minimum required size for the Journal volume using the default parameters?

Accepted Answer

C

Explanation: To calculate the minimum required size for the Journal volume, we can use the provided formula and input the given parameters: Average Write Traffic: 5 Mb/s Required Rollback Time: 24 hours (which is 24 * 60 * 60 = 86,400 seconds) Default Parameters: Assuming the image access log percentage is 20% (which is a common default), and the reserved for marking is negligible. Using the formula: 	ext{Journal size} = 1.05 	imes (	ext{write traffic}) 	imes (	ext{rollback time in seconds}) / (1 - 	ext{image access log percentage})Journal​size=1.05×(write​traffic)×(rollback​time​in​seconds)/(1−image​access​log​percent age) We plug in the values: 	ext{Journal size} = 1.05 	imes (5 	ext{ Mb/s}) 	imes (86,400 	ext{ seconds}) / (1 - 0.2)Journal​size=1.05×(5​Mb/s)×(86,400​seconds)/(1−0.2) Converting Mb to GB (1 Mb = 1/8,000 GB): 	ext{Journal size} = 1.05 	imes (5/8,000 	ext{ GB/s}) 	imes 86,400 / 0.8Journal​size=1.05×(5/8,000​GB/s)×86,400/0.8 	ext{Journal size} = 1.05 	imes 0.000625 	ext{ GB/s} 	imes 86,400 / 0.8Journal​size=1.05×0.000625​GB/s×86,400/0.8 	ext{Journal size} = 1.05 	imes 54 	ext{ GB} / 0.8Journal​size=1.05×54​GB/0.8 	ext{Journal size} = 70.875 	ext{ GB}Journal​size=70.875​GB Since we need to round up to ensure we have enough space, the minimum required size for the Journal volume is approximately 72.4 GB. This calculation ensures that the Journal volume is adequately sized to handle the write traffic and maintain the required rollback time, providing a buffer for the image access log1.

Question 2

Accepted Answer

A

Explanation: Configure the zone including Unity ports and RP ports. Perform the Unity cluster conversion (SE to EX). Update the licenses to EX. Confirm whether the RP cluster is added to Unity1. The Conversion wizard will convert both clusters on the RP system. Note that the conversion will convert the RP/SE system with the VNX arrays to a full RP system. RP/EX applies to licensing only. There are no additional configurations changes required on the VNX arrays1. For more detailed steps and scenarios, you may refer to the “Using RP for Mid-Range Array Refresh” document available on Dell EMC Online Support, which is laid out in several scenarios1.

Question 4

DRAG DROP What is the correct sequence of steps for Snap-based replication on XtremIO? https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/Dell_D-RP-DY-A-24/page_13_img_1.jpg

Accepted Answer

Explanation: The correct sequence of steps for Snap-based replication on XtremIO is: Create the snapshot Get the DIFF between the snapshot and the root volume Create a second snap, and then retrieve the DIFF between the first and second snapshot Transfer the DIFF Create and promote the snapshot Snap-based replication on XtremIO involves the following steps: Create the snapshot: This step involves taking a snapshot of the source volume that will be used as the baseline for replication. Get the DIFF between the snapshot and the root volume: Here, the differences between the snapshot and the root volume are calculated. This is necessary to understand what changes have been made since the last snapshot. Create a second snap, and then retrieve the DIFF between the first and second snapshot: A second snapshot is created to capture the latest state of the volume. The differences (DIFF) between the first snapshot and the second snapshot are then calculated. Transfer the DIFF: The differences identified between the snapshots are transferred to the target volume. This ensures that only the changes are replicated, optimizing the replication process. Create and promote the snapshot: Finally, the snapshot is created and promoted to ensure the target volume is updated with the latest changes. This sequence ensures efficient and accurate replication by focusing on the changes between snapshots, rather than replicating the entire volume each time.

zoning between the RPAs and the VNX ports is completed and the RPA
ports are available in the connectivity status on the VNX.
What is the next step to complete?

Accepted Answer

D

Explanation: After completing the zoning between the RPAs and the VNX ports and ensuring the RPA ports are available in the connectivity status on the VNX, the next step is to create a storage group on the VNX for RecoverPoint. This step is crucial to logically group the LUNs that will be managed and replicated by the RecoverPoint system. Reference: Dell RecoverPoint for Virtual Machines 6.0.1 vSphere HTML5 Plugin Administrator's Guide, Chapter on implementing RecoverPoint/EX clusters using VNX splitters.

Question 8

During the write phase of RecoverPoint replication, when does the RPA send an acknowledgement back to the write splitter?

Accepted Answer

A

Explanation: In the write phase of RecoverPoint replication, the write splitter intercepts write data from the production host and sends it to the RecoverPoint Appliance (RPA). The RPA then immediately acknowledges receipt of the write data to the write splitter1. This acknowledgement occurs as soon as the RPA receives the write, which is before the distribution phase or any acknowledgements from other copies involved in the replication process1. The prompt acknowledgement allows the write splitter to continue processing other writes, ensuring efficient replication and system performance1. For detailed information on the write phase and the role of the RPA and write splitter in RecoverPoint replication, it is advisable to consult the official Dell RecoverPoint documentation or contact Dell EMC support.

Question 9

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?

Accepted Answer

C

Explanation: Failover Execution: When a Consistency Group failover is performed to a remote copy, the remote copy becomes the new production copy. Journal Content Handling: The point-in-time images that were stored in the copy Journal, which was associated with the remote copy, are deleted as part of the failover process1. Post-Failover State: After the failover, the system will start fresh journaling for the new production copy, and the previous point-in-time images are no longer required1. This process ensures that the Journal is used efficiently and only contains relevant point-in-time images for the current production copy1.

Question 13

A system administrator wants to configure a RecoverPoint cluster and the required Repository
volume created on a VNX accessible by all RPAs. However, the Repository
volume is not visible in Deployment Manager to continue the RecoverPoint cluster configuration.
What is a possible reason for this situation?

Accepted Answer

D

Explanation: Check LUN Configuration: The Repository volume must be accessible by all RPAs. If it is configured as a private LUN, it would only be accessible by a single host or a limited set of hosts, which could be why it is not visible in the Deployment Manager1. Modify LUN Settings: To resolve this, the LUN should be reconfigured to be accessible by all RPAs. This may involve changing the LUN from private to public or shared within the storage array settings. Verify Visibility: After reconfiguring the LUN, verify that it is now visible in the Deployment Manager to continue with the RecoverPoint cluster configuration. It is essential that the Repository volume is not set as a private LUN to ensure that all RPAs within the cluster can access it for proper configuration and operation of the RecoverPoint system1.
