Question 2
Domain 1: Cloud ConceptsWhich AWS Cloud benefit eliminates the need for users to try estimating future infrastructure usage?
Correct answer: C
Explanation
Elasticity is “the ability to add or remove resources based on demand,” so users do not need to guess future infrastructure needs. The source also says AWS offers “Elastic Capacity” and that “There’s no need to guess your capacity requirements in advance.”
Why each option is right or wrong
A. Easy and fast deployment of applications in multiple Regions around the world.
B. Security of the AWS Cloud.
C. Elasticity of the AWS Cloud.
AWS defines elasticity as the ability to add or remove resources based on demand, so the service can match capacity to actual usage instead of requiring advance forecasting. The AWS Cloud value statement explicitly says there is “no need to guess your capacity requirements in advance,” which is the exact problem described in the question.
D. Lower variable costs due to massive economies of scale.
