How to approach this question
Look for examples of increasing resources either vertically (size) or horizontally (quantity).
Full Answer
Scalability refers to the ability to adjust resources to meet demand. This can be done vertically (scaling up by adding more CPU/RAM to a single resource) or horizontally (scaling out by adding more instances of a resource).
Common mistakes
Confusing scalability with elasticity. Scalability is the *ability* to scale; elasticity is the *automated* scaling based on real-time demand.
