Which term describes the sharing of computing resources among multiple tenants with isolation?

• A. On-demand self service
• B. Pooled resources
• C. Rapid elasticity
• D. Measured service

Answer: (B)

The concept being tested is sharing computing resources among multiple tenants with isolation, which is described by pooled resources. In cloud environments, a single pool of compute, storage, and network resources is shared among many tenants, but virtualization and strict access controls provide logical isolation so each tenant’s data and operations stay separate. This combination—shared infrastructure plus isolation—defines pooled resources. The other terms describe different capabilities: on-demand self-service is about provisioning resources automatically, rapid elasticity is about scaling quickly, and measured service is about metering usage for billing.
