Question 40
UnclassifiedWhich of the following metrics are frequently immature?
Correct answer: A
Explanation
Metrics around Infrastructure as a Service (IaaS) storage and network environments are frequently immature because cloud providers and tenants often lack standardized, transparent measurement methods for these shared resources. In practice, storage and network usage are harder to attribute and benchmark than compute, so the metrics are less developed and less consistent.
Why each option is right or wrong
A. Metrics around Infrastructure as a Service (IaaS) storage and network environments
IaaS storage and network measurements are commonly the least developed because the provider controls the underlying shared fabric, so tenants typically cannot directly observe or independently verify the raw counters used to calculate usage. In cloud billing and monitoring practice, compute metrics are usually more mature and standardized, whereas storage and network environments still vary by provider and service model, leaving attribution, benchmarking, and consistency comparatively weak.
B. Metrics around Platform as a Service (PaaS) development environments
C. Metrics around Infrastructure as a Service (IaaS) computing environments
D. Metrics around specific Software as a Service (SaaS) application services
