A cloud security engineer is designing a disaster recovery strategy for a critical application deployed in a public cloud. The strategy includes replicating application data and infrastructure to a geographically distant region. This approach ensures that if one region experiences a complete outage, the application can quickly resume operations in another. Which cloud computing characteristic is being leveraged here?
- AOn-demand self-service
- BElasticity
- CBroad network access
- DResilience
Show answer & explanationAnswer & explanation
Correct answer: D. Resilience
Resilience in cloud computing refers to the ability of a system to recover from failures and continue to function, often achieved through redundancy, fault tolerance, and disaster recovery strategies like replicating resources across different regions.
Why the other options are wrong
- A. On-demand self-service refers to users provisioning resources without human interaction from the provider.
- B. Elasticity is the ability to scale resources up or down rapidly, not directly related to recovery from outages.
- C. Broad network access means services are available over the network, not a disaster recovery characteristic.
Cloud Resilience
The ability of a cloud system to withstand failures, adapt to changing conditions, and recover quickly from disruptions while maintaining acceptable levels of service.
- Achieved through redundancy, fault tolerance, and disaster recovery
- Often involves multi-region deployments
- Ensures business continuity
