Amazon Amazon Certifications CLF-C01 Questions & Answers

• Question 1741:

  Which AWS Cloud best practice uses the elasticity and agility of cloud computing?

  A. Provision capacity based on past usage and theoretical peaks

  B. Dynamically and predictively scale to meet usage demands

  C. Build the application and infrastructure in a data center that grants physical access

  D. Break apart the application into loosely coupled components

  Correct Answer: B

  In a traditional computing environment, you provision capacity based on an estimate of a theoretical maximum peak. This can result in periods where expensive resources are sitting idle or occasions of insufficient capacity. With cloud computing, you can access as much or as little capacity as you need and dynamically scale to meet actual demand, while only paying for what you use.
