Today Question:
Which property guarantees long-term data persistence in the cloud?
A) Durability
B) Availability
C) Scalability
D) Elasticity
Correct Answer: A
Explanation
Durability in the cloud refers to the system’s ability to preserve data without loss even in the event of hardware failures, network outages, or other incidents. Cloud providers achieve high durability by replicating data across multiple geographically separated data centers and applying integrity-checking mechanisms. Unlike availability, which measures how accessible a service is at a given moment, durability ensures that stored data will not be lost and remains consistent over the long term. Choosing services with high durability is essential for sensitive or critical data.
