Which statement correctly distinguishes high availability from elasticity?
Show answer and explanation
Answer: A
The two concepts answer different questions. High availability is about engineering redundancy and fault isolation so a workload keeps running through component failures and maintenance; elasticity is about growing or shrinking capacity to track demand, paying only for what is actually needed.
They reinforce each other in a good architecture, but neither implies the other.
Why the other options are wrong
- B. Neither term touches pricing negotiation, and encryption is a data-protection concept separate from both.
- C. They overlap in outcome only; one addresses uptime through failure, the other capacity through demand.
- D. Both properties exist on AWS in full — availability and elasticity are cloud-native, not platform-limited.
