VMware vSphere 6 Beta Foundations — Question 14

Which are two characteristics of a RAID-5 storage configuration? (Choose two.)

Answer options

• A. Data remain available with the loss to two storage devices.
• B. It uses less storage capacity than mirroring with the same level of availability.
• C. Data is striped across multiple storage devices.
• D. It requires a minimum of five storage devices.

Correct answer: B, C

Explanation

The correct answers are B and C because RAID-5 is designed to use less storage than mirroring while still providing data availability through striping. Option A is incorrect as RAID-5 can only tolerate the failure of one storage device, and option D is also wrong since it requires a minimum of three storage devices, not five.
