CompTIA Network+ (N10-009) — Question 129

Cloud computing has the capability to meet increased and decreased demands for computing infrastructure for a short period of time. Which of the following best describes this characteristic?

Answer options

• A. Efficiency
• B. Elasticity
• C. Multitenancy
• D. Scalability

Correct answer: B

Explanation

The correct answer is B, Elasticity, as it specifically refers to the ability to quickly scale resources up or down based on demand. Options A (Efficiency) and C (Multitenancy) do not directly address the ability to adjust resource levels, while D (Scalability) generally refers to the ability to increase capacity but does not emphasize the rapid adjustment aspect.
