Answer options:

High Availability
B.
Elasticity
C.
Disaster Recovery
D.
Predictability
How to approach this question
Identify the cloud characteristic that deals with dynamic, unpredictable workloads.
Full Answer
B.Elasticity✓ Correct
Elasticity
Elasticity allows cloud systems to automatically scale out (add resources) during traffic spikes and scale in (remove resources) when traffic drops, ensuring performance without overpaying.
Common mistakes
Confusing elasticity with scalability. Scalability is the general ability to grow; elasticity implies automatic, dynamic scaling based on unpredictable demand.
