Dell EMC Associate – PowerEdge Server Specialist — Question 11

A RAID 5 configuration with 20 hard drives loses one hard drive. How many additional hard drive failures can this configuration tolerate before experiencing data loss?

Answer options

• A. 0
• B. 1
• C. 2
• D. 3

Correct answer: A

Explanation

RAID 5 can tolerate a single drive failure due to its use of parity data for redundancy. Once one drive fails, the array is in a degraded state, meaning it cannot sustain any further drive failures without risking data loss. Therefore, the correct answer is A, while B, C, and D are incorrect as they imply the system could withstand additional failures.
