CompTIA Security+ (SY0-501) — Question 106

In a corporation where compute utilization spikes several times a year, the Chief Information Officer (CIO) has requested a cost-effective architecture to handle the variable capacity demand. Which of the following characteristics BEST describes what the CIO has requested?

Answer options

• A. Elasticity
• B. Scalability
• C. High availability
• D. Redundancy

Correct answer: A

Explanation

The correct answer is A, Elasticity, as it refers to the ability to dynamically allocate and deallocate resources based on demand, which is ideal for handling variable capacity needs. Scalability (B) implies a system can grow in size or capability but does not specifically address the dynamic aspect of resource allocation. High availability (C) focuses on system uptime and reliability, while redundancy (D) refers to duplicating components to ensure reliability, neither of which directly relates to managing fluctuating demand.
