• Question 21:

  An online retail company has seasonal sales spikes several times a year, primarily around holidays Demand is lower at other times. The company finds it difficult to predict the increasing infrastructure demand for each season. Which advantages of moving to the AWS Cloud would MOST benefit the company? (Select TWO )

  A. Global footprint

  B. Elasticity

  C. AWS service quotas

  D. AWS shared responsibility model

  E. Pay-as-you-go pricing

  Correct Answer: BE

  The advantages of moving to the AWS Cloud that would MOST benefit the company in this scenario are:

  B. Elasticity: The company can take advantage of the elasticity of the AWS Cloud to easily scale its infrastructure up or down as demand fluctuates during the seasonal sales spikes. This can help avoid overprovisioning during low demand periods, which can result in unnecessary costs.

  E. Pay-as-you-go pricing: The company can benefit from the pay-as-you-go pricing model of the AWS Cloud, which allows it to only pay for the resources it uses. This can help reduce costs during low demand periods and avoid the need to make large upfront investments in infrastructure that may not be fully utilized.
