ISC2 Certified Cloud Security Professional (CCSP) Practice Question

A SOC 2 Type II report evaluates the design and operating effectiveness of a service provider's controls over a defined review period that must span a minimum of six months. ISO/IEC 27017 certification and ISO/IEC 27001 Statements of Applicability validate control design (and the fact that controls are implemented) but do not require evidence of continuous effectiveness across a defined multi-month window. A PCI DSS Level 1 Attestation of Compliance demonstrates that cardholder-data controls met the standard at the time of the annual assessment and that the organization is required to maintain ongoing compliance, but it does not, by itself, document control operation across a specific six-month interval. Therefore, the SOC 2 Type II report provides the strongest evidence that controls have functioned effectively over the desired period.
