QuestionQ1

Dell EMC RecoverPoint and RecoverPoint for Virtual Machines (VMs) Solutions Design

Why must the Write Splitter be installed on ESXi servers that host Dell EMC RecoverPoint for VMs vRPAs and Production VMs?

  • A All ESXi servers, managed by the vCenter Server with the RecoverPoint for VMs Plug-in, contain the Write Splitter
  • B Writes to the Production VMs must be copied and sent to the assigned vRPA
  • C vRPAs use the Write Splitter to communicate with the vCenter Server Plug-in
  • D Writes to the Production VMs must be copied and sent to the Production Journal
Explanation

The RecoverPoint for VMs write splitter intercepts each write issued by a protected production VM, copies it, and sends the copy to the assigned vRPA for replication processing. The vRPA subsequently manages replication and journal handling.

QuestionQ2

Dell EMC RecoverPoint and RecoverPoint for Virtual Machines (VMs) Solutions Design

Which factor determines the required Journal size for each Dell EMC RecoverPoint for VMs Consistency Group?

  • A It failover is required for each copy in the Consistency Group
  • B How far back in time Production can be recovered
  • C Size of each VMDK in the Consistency Group’s Replication set
  • D If synchronous replication is being used
Explanation

Journal capacity is determined by the recovery retention window: the farther back in time the production image must be recoverable, the more recovery points the journal must retain. Dell documents that the retention policy defines how far back the copy image can be rolled back.

QuestionQ3

Dell EMC NetWorker Solutions Design

A customer has completed an evaluation of multiple Dell EMC NetWorker servers and now wants to activate the software. They also want to centralize the NetWorker licenses. Which information is required?

  • A Sales order number and hostname of the NetWorker server
  • B LAC number, IP address, and hostname of the NetWorker server
  • C Sales order number and hostname of the license server
  • D LAC number, IP address, and hostname of the license server
Explanation

A centralized NetWorker deployment uses a served license. Dell activation requires a Sales Order number or LAC number and, for a served license, the IP address and hostname of the license server. A LAC number together with the license server IP address and hostname meets these requirements.

QuestionQ5

Dell EMC RecoverPoint and RecoverPoint for Virtual Machines (VMs) Solutions Design

Which Dell EMC array uses snap-based replication when it is protected by RecoverPoint?

  • A VNX
  • B XtremIO
  • C Unity
  • D VPLEX
Explanation

XtremIO uses RecoverPoint’s splitterless snap-based replication option, which replicates array snapshots rather than relying on the standard write-splitter approach. Dell documentation identifies XtremIO as an exception that uses snap-based replication; Unity does not support it.
