A risk scenario is a hypothetical situation that describes how a risk event could adversely affect an organization's objectives, assets, or operations. A risk scenario can be used for risk analysis, which is the process of estimating the likelihood and impact of the risk event, and evaluating the effectiveness and efficiency of the risk response1.
One of the essential components of a risk scenario is the threat type, which is the source or cause of the risk event. The threat type can be classified into various categories, such as natural, human, technical, environmental, or legal. The threat type can help to define the characteristics, motivations, capabilities, and methods of the risk event, and to identify the potential vulnerabilities and exposures of the organization. The threat type can also help to determine the frequency and severity of the risk event, and to select the appropriate risk response strategies and controls23.
The other options are not the components of a risk scenario, but rather the outcomes or inputs of risk analysis.
Risk appetite is the amount and type of risk that an organization is willing to accept in pursuit of its objectives. Risk appetite can help to guide the risk analysis by providing a high-level statement of the desired level of risk taking and tolerance4. Risk tolerance is the acceptable variation in the outcomes related to specific objectives or risks. Risk tolerance can help to measure the risk analysis by providing quantitative or qualitative indicators of the acceptable range of risk exposure and performance4. Residual risk is the remaining risk after the risk response has been implemented. Residual risk can help to monitor the risk analysis by providing feedback on the effectiveness and efficiency of the risk response and the need for further action. References =

* A vulnerability assessment is a process of identifying and evaluating the weaknesses or gaps in an application that may expose it to potential threats or attacks.
* When vulnerability assessment results identify a weakness in an application, the first thing that a risk practitioner should do is to assess the risk to determine mitigation needed. This means that the risk practitioner should analyze the likelihood and impact of the weakness being exploited, the existing controls that are in place to prevent or reduce the exploitation, and the residual risk that remains after applying the controls.
* Assessing the risk to determine mitigation needed helps to prioritize the actions that are required to address the weakness, such as implementing new or additional controls, accepting the risk, transferring the risk, or avoiding the risk.
* The other options are not the first things that a risk practitioner should do when vulnerability assessment results identify a weakness in an application. They are either secondary or not essential for risk management.

and B are incorrect. Estimation of risk's consequence and priority for awareness is conducted by using probability and impact matrix. These matrices specify the mixture of probability and impact that directs to rating the risks as low, moderate, or high priority. Answer: C is incorrect. A risk scenario is a description of an event that can lay an impact on business, when and if it would occur. Some examples of risk scenario are of: Having a major hardware failure Failed disaster recovery planning (DRP) Major software failure
