CCSK · Question #103

What are the NIST defined essential characteristics of cloud computing?

The correct answer is D. Broad network access, rapid elasticity, measured service, on-demand self-service, and resource. NIST SP 800-145 defines exactly five essential characteristics of cloud computing: on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service.

Why each option

NIST SP 800-145 defines exactly five essential characteristics of cloud computing: on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service.

ARapid elasticity, compliance readiness, and resource pooling

Compliance readiness is not one of the NIST-defined essential characteristics; it replaces measured service incorrectly.

BBroad network access, measured service, multifactor configurability, and resource pooling

Multifactor configurability is not a NIST-defined characteristic and this option omits on-demand self-service.

CBroad network access, automatic patching, compliance readiness, and resource pooling

Automatic patching is not one of the five NIST characteristics, and compliance readiness is also not included in the official definition.

DBroad network access, rapid elasticity, measured service, on-demand self-service, and resourceCorrect

According to NIST SP 800-145, the five essential characteristics are on-demand self-service (users provision resources without human interaction), broad network access (resources available over the network via standard mechanisms), resource pooling (multi-tenant model with dynamic resource assignment), rapid elasticity (capabilities scale quickly to demand), and measured service (resource usage is monitored and reported). Only option D captures all five of these official characteristics without introducing incorrect additions.

EBroad network access, rapid elasticity, automatic patching, and resource pooling

Automatic patching is not a NIST-defined essential characteristic, and this option omits both on-demand self-service and measured service.
