Question

which of the following best describes \scalability\ in cloud computing?
a the ability to reduce costs quickly
b the fixed amount of resources in the cloud
c the ability to physically expand hardware
d the ability to dynamically adjust resources based on demand

Explanation:

Scalability in cloud computing refers to the ability to dynamically adjust resources (such as computing power, storage) based on demand. This allows businesses to efficiently manage resources, neither over - provisioning (which would waste costs) nor under - provisioning (which could lead to poor performance). Option A is about cost reduction which is related but not the core of scalability. Option B is about a fixed amount which is contrary to scalability. Option C is about physical expansion of hardware which is not the cloud - based, virtualized concept of scalability.

Answer:

D. The ability to dynamically adjust resources based on demand
