CompTIA Security+ (SY0-501) — Question 906

Which of the following is a resiliency strategy that allows a system to automatically adapt to workload changes?

Answer options

• A. Fault tolerance
• B. Redundancy
• C. Elasticity
• D. High availability

Correct answer: C

Explanation

The correct answer is C, Elasticity, as it refers to the ability of a system to scale resources up or down automatically based on demand. Fault tolerance (A) focuses on maintaining service availability despite failures, Redundancy (B) involves duplicating components to ensure reliability, and High availability (D) aims to ensure systems are operational with minimal downtime, but none directly address automatic adaptation to workload changes like Elasticity does.
