Dell EMC Associate – Cloud Infrastructure and Services v4 — Question 25

Which two are key requirements for fault tolerance?

Answer options

• A. Document SPOF and Fault Elimination
• B. Fault Isolation and Eliminate SPOF
• C. Network Isolation and Eliminate SPOF
• D. RAID Storage and Fault Isolation

Correct answer: B

Explanation

The correct answer is B because fault isolation helps contain failures to specific areas, preventing them from affecting the entire system, while eliminating Single Points of Failure (SPOF) is crucial for maintaining overall system reliability. The other options either focus on documentation or include elements that do not directly contribute to fault tolerance in the same way.
