Which of the following is a drawback in the use of quantitative risk analysis?

The drawback in the use of quantitative risk analysis is that it requires more resources than other methods. Quantitative risk analysis is a method of risk analysis that assigns numeric values to the exposures of assets, the impact and likelihood of risk events, and the cost and benefit of risk responses. Quantitative risk analysis can provide more precise and objective results, and support the risk-based decision making process. However, quantitative risk analysis also requires more resources than other methods, such as data, time, expertise, and tools, to collect, validate, and analyze the quantitative information, and to perform the complex calculations and simulations. Quantitative risk analysis may also be limited by the availability, reliability, and accuracy of thedata, and the assumptions and models used. Assigning numeric values to exposures of assets, producing the results in numeric form, and being based on impact analysis of information assets are not drawbacks, but characteristics of quantitative risk analysis. References = CRISC Review Manual, 6th Edition, ISACA, 2015, page 49.
