Question 2: What does 'elasticity' mean in the context of AWS cloud computing?
- The ability to automatically scale resources up or down based on demand (Correct answer)
- The ability to move workloads between regions
- The ability to back up data automatically
- The ability to encrypt data in transit
Correct answer: The ability to automatically scale resources up or down based on demand

Question 4: In cloud computing, what is meant by 'high availability'?
- A system that never requires maintenance
- A system designed to minimize downtime and remain operational despite failures (Correct answer)
- A system that can process unlimited requests simultaneously
- A system that automatically reduces costs during peak hours
Correct answer: A system designed to minimize downtime and remain operational despite failures
High availability describes architectures designed to reduce downtime by eliminating single points of failure and enabling rapid recovery.
Question 5: Which of the following best describes the AWS 'Pay-as-you-go' pricing model?
- Pay a fixed monthly fee regardless of usage
- Pay only for the resources you consume with no upfront commitment (Correct answer)

Correct answer: A geographic area containing multiple, isolated Availability Zones
An AWS Region is a physical location in the world that contains two or more Availability Zones, providing geographic distribution of resources.
Question 7: Which cloud computing characteristic allows resources to be provisioned without requiring human interaction with each service provider?
- Broad network access
- Resource pooling
- On-demand self-service (Correct answer)
- Measured service
Correct answer: On-demand self-service
On-demand self-service is the NIST characteristic that lets users provision resources automatically via a portal or API without needing to call or email the provider.
