Exam 22 Question 23 - Wrong Answer

[alireza-dashchi]

Original Answer:
D. Scalability

Proposed Correct Answer:
A. Elasticity

Reasoning:
Elasticity is the AWS benefit that specifically refers to the automatic scaling of resources (both up and down) to meet fluctuating workloads. This is a core feature of services like Auto Scaling, Elastic Load Balancing, and AWS Lambda. While scalability is related, it refers to the ability to increase capacity in response to growth rather than the dynamic adjustment to variable demand.

Supporting Evidence:
• The AWS Well-Architected Framework defines elasticity as the capability of adjusting resources dynamically based on demand.
• AWS documentation frequently uses elasticity in the context of scaling up and down automatically to optimise resource use and cost.
