Objective 5.2

220-1201

Given a scenario, troubleshoot drive and RAID issues.

Objective 5.2 sits in Hardware and Network Troubleshooting, which carries 28% of the A+ Core 1 exam. The questions below are original, written from the official objective title above, and each explanation cites the CompTIA page it rests on.

5-2Hardware and Network Troubleshooting

A storage pool administrator creates a virtual disk with simple resiliency across four physical drives. One drive in the pool fails. What is the most likely outcome for the virtual disk?

Data on the virtual disk is lost and cannot be recovered.Correct · your answerCorrect: simple spaces have no redundancy, so failure means data loss.
Data remains accessible from a mirrored copy on another drive.This describes mirror resiliency, which duplicates data across drives.
Data is reconstructed automatically from parity information.This describes parity resiliency, which reconstructs data from parity.
Data is cached on a faster drive until the failure is resolved.This describes a caching feature, not a resiliency type, and does not apply to simple spaces.

Correct.

Concept

Simple resiliency stripes data across drives for maximum performance and capacity but provides no redundancy.

Why A

Striping spreads one logical extent over every member, so the surviving drives each hold fragments with gaps where the failed member's share used to sit. Nothing is stored anywhere from which those gaps can be filled back in, and a partial stripe is not a usable file.

Source

Simple spaces provide no resiliency or redundancy. Data is striped across multiple drives, maximizing performance and storage capacity utilization. However, because there's no redundancy, the failure of a single drive results in data loss.
