The BEST answer is A because adding emerging technology to an existing process changes the operating environment and can introduce new threats, vulnerabilities, dependencies, and uncertainty. Those changes can increase either the likelihood of a risk event, the impact of the event, or both. The uploaded CRISC notes support this by stating that business risk changes frequently, the current and future environment must be gathered when identifying and assessing IT risk, and emerging threats should be recognized and managed.
ISACA’s CRISC outline states that Domain 2: Risk Assessment covers threats and vulnerabilities to people, processes, and technology, including likelihood and impact of threats, vulnerabilities, and risk scenarios. ISACA also explains that risk scenarios should be created based on business context, system environment, and pertinent threats, and that impact can affect confidentiality, integrity, or availability of assets.
B is incorrect because changing the analysis method does not itself change the actual likelihood or impact of the risk. C is incorrect because introducing controls should normally reduce likelihood or impact. D may increase residual exposure if risk is accepted inappropriately, but acceptance does not itself change the inherent likelihood or impact of the risk scenario.
