Dell EMC D-MSS-DS-23 Dell Midrange Storage Solutions Design 2023 Exam Practice Test

Answer : B

In the PowerStore sizing tool, the default Data Reduction Ratio (DRR) values for block and file workloads are Block = 4:1 and File = 2:1. These values represent the expected reduction in data size due to compression and deduplication, which helps in planning the storage capacity and performance requirements effectively.

Answer : B

The tool that a Solution Architect must use to check the compatibility of a new storage solution with an existing infrastructure is E-Lab Navigator. E-Lab Navigator is a comprehensive online database provided by Dell that includes compatibility information for various hardware and software configurations. It helps ensure that new storage solutions are compatible with existing infrastructure, reducing the risk of integration issues. Reference: Dell E-Lab Navigator Overview

Answer : D

When connecting Disk Array Enclosures (DAEs) to SAS ports on a Dell Unity XT DPE (Disk Processor Enclosure) with only two ports available on each SP (Storage Processor), the recommended order is DAE 1 to SAS Bus 0, DAE 2 to SAS Bus 1, and DAE 3 to SAS Bus 0. This configuration helps in balancing the load across the available SAS ports, ensuring optimal data flow and performance. Reference: Dell Unity XT Configuration Guide

Answer : C

When planning and sizing a Midrange storage solution, two key guidelines for optimal performance are to consolidate workloads and design for resilience. Consolidating workloads helps in maximizing the utilization of storage resources, reducing overhead, and improving performance. Designing for resilience ensures that the storage solution can handle failures and continue to operate effectively, maintaining data availability and performance. These practices are critical for achieving reliable and efficient storage solutions. Reference: Dell Midrange Storage Planning Guide
