Question 1
Which benefit of the AWS Cloud allows a company to increase or decrease computing resources as demand changes?
- Elasticity
- Compliance auditing
- Data encryption
- Hardware ownership
Correct Answer: 1
Explanation
Elasticity is the ability to automatically or manually increase and decrease cloud resources according to workload requirements. For example, an application can use additional compute capacity during a period of high traffic and reduce capacity when demand falls. This helps organizations avoid maintaining excessive infrastructure for occasional peaks. AWS provides multiple services and features that support elastic resource management. Elasticity is different from scalability, although the concepts are closely related. Elasticity specifically emphasizes matching resource capacity to changing demand, which can improve efficiency and reduce unnecessary infrastructure costs.
Question 2
A company wants to deploy applications in multiple geographic locations to reduce latency for users around the world. Which AWS infrastructure component should the company primarily consider?
