Which of the following is an advantage of cloud computing?

• A. Rapid elasticity
• B. Unpredictable cost
• C. Security concerns
• D. Policy concerns

Answer: (A)

Rapid elasticity lets you scale resources up or down quickly as demand changes, which is a key advantage of cloud computing. This flexibility means you can absorb traffic spikes by provisioning extra compute, storage, or services on the fly, and then release them when demand falls, without long lead times or wasted capacity. That agility speeds up deployment and enables experimentation, while keeping operations responsive to business needs. The other options describe potential downsides or challenges rather than benefits: costs can be unpredictable if not managed, security concerns are issues to address, and policy concerns relate to governance requirements rather than a direct advantage of the cloud.
