D-PWF-DY-A-00 EMC Dell PowerFlex Implementation Achievement Free Practice Exam Questions (2025 Updated)

To create aproduction-ready PowerFlex Management Platform (PFMP) cluster, a minimum ofthree nodesis required. This requirement is verified by theDell PowerFlex Deployment Guideand other official Dell documentation. The three-node configuration ensures high availability and fault tolerance for the management platform, which is critical for managing and monitoring the PowerFlex environment.

High Availability:A three-node cluster allows for redundancy and failover capabilities. If one node fails, the remaining two nodes can continue to manage the cluster without interruption.

Quorum Maintenance:In distributed systems like PowerFlex, maintaining quorum (a majority of nodes agreeing on the state of the system) is essential for consistency and reliability. A three-node cluster ensures that quorum can be maintained even if one node goes offline.

Best Practices:Dell recommends a minimum of three nodes for production environments to align with industry standards for high availability and scalability.

A. 9:While nine nodes can be used for larger-scale deployments, it is not the minimum requirement for a production cluster.

B. 1:A single-node configuration is only suitable for non-production or lab environments where high availability is not a concern. It is not supported for production use.

C. 5:Five nodes provide additional redundancy but are not the minimum requirement for a production cluster.

Dell PowerFlex Deployment Guide (Version 4.x):Specifies the minimum number of nodes required for a production PowerFlex Management Platform cluster.

PowerFlex Best Practices Guide:Recommends a three-node configuration for production environments to ensure high availability and fault tolerance.

Why three nodes are required:Why the other options are incorrect:Key References:

After deploying three MDMs (Metadata Managers) in a PowerFlex cluster, the next critical step is to convert the cluster to a multi-node configuration. This ensures the cluster leverages the redundancy and fault tolerance provided by the three MDMs (one active primary, one standby, andone Tie-Breaker).

Key References from Dell PowerFlex Documentation:

PowerFlex 4.x Administrator Guide:

A multi-node cluster requires at least three MDMs (two primary MDMs in active/standby roles and one Tie-Breaker). After adding these MDMs, the cluster must be explicitly converted to a multi-node configuration using the command:
