CompTIA A+ Core 1 (220-1201)Virtualization and Cloud ComputingEasy
A company is experiencing rapid growth and needs to quickly scale its computing resources up or down based on fluctuating demand, without requiring manual intervention. Which characteristic of cloud computing directly addresses this need?
- ABroad Network Access
- BRapid Elasticity
- CResource Pooling
- DMeasured Service
Show answer & explanationAnswer & explanation
Correct answer: B. Rapid Elasticity
Rapid elasticity is a key characteristic of cloud computing that allows computing resources to be provisioned and de-provisioned quickly and automatically to scale with demand. This enables companies to handle unexpected spikes or drops in workload efficiently.
Why the other options are wrong
- A. Broad network access means resources are available over the network, not about scaling.
- C. Resource pooling means resources are shared among multiple tenants, not directly about auto-scaling.
- D. Measured service tracks resource usage for billing, not the ability to scale automatically.
Rapid Elasticity
A characteristic of cloud computing that allows computing resources to be provisioned and de-provisioned quickly and automatically, scaling rapidly commensurate with demand.
- Enables dynamic scaling up or down.
- Often automated, without human intervention.
- Key for handling fluctuating workloads.
Memory trick: On-Demand, Broad Network, Resource Pool, Rapid Elasticity, Measured Service.
