An IT infrastructure consultant is evaluating cloud operational requirements for an enterprise client. Match each operational infrastructure scenario on the left with the essential cloud characteristic on the right that directly enables it.
- A corporate analytics system automatically expands and contracts compute instances based on real-time memory usage thresholds during unannounced data bursts.Rapid Elasticity
- A multi-tenant database platform dynamically reallocates physical RAM and storage IOPS across different business clients based on shifting daily workload demands while keeping tenant data isolated.Resource Pooling
- A developer configures, provisions, and spins up temporary virtual machine test environments instantly via an automated portal without requiring administrator approval or intervention.On-Demand Self-Service
- A department manager receives an itemized monthly billing statement showing exact gigabytes of storage consumed per hour and total network egress bandwidth used.Measured Service
Cevap
Rapid Elasticity matches automatic dynamic resource scaling; Resource Pooling matches multi-tenant physical hardware abstraction and reallocation; On-Demand Self-Service matches automated provisioning via web portal without administrator intervention; Measured Service matches itemized, granular usage tracking and billing.
Each scenario maps directly to essential cloud characteristics defined by CompTIA: automatic dynamic scaling maps to Rapid Elasticity, multi-tenant dynamic physical resource sharing maps to Resource Pooling, unilateral portal provisioning maps to On-Demand Self-Service, and granular consumption metering maps to Measured Service.
