Dell EMC Associate – Cloud Infrastructure and Services v3 — Question 45

An organization deployed a storage system that is configured with erasure coding. The erasure coding technique divides data into five data segments and two coding segments.
What is the maximum number of drive failures supported in the storage system?

Answer options

• A. 2
• B. 5
• C. 7
• D. 10

Correct answer: A

Explanation

The correct answer is A, as the system can sustain failures equal to the number of coding segments, which is two in this case. The data segments alone do not provide redundancy; rather, it is the coding segments that allow for recovery from drive failures. Therefore, options B, C, and D are incorrect as they exceed the supported failure count.
