Explanation:
The risk response process is triggered when a risk exceeds the enterprise's risk tolerance level. The acceptable variation relative to the achievement of an objective is termed as risk tolerance. In other words, risk tolerance is the acceptable deviation from the level set by the risk appetite and business objectives.
Risk tolerance is defined at the enterprise level by the board and clearly communicated to all stakeholders. A process should be in place to review and approve any exceptions to such standards.
Incorrect Answers:
A, C: Risk appetite level is not relevant in triggering of risk response process. Risk appetite is the amount of risk a company or other entity is willing to accept in pursuit of its mission. This is the responsibility of the board to decide risk appetite of an enterprise. When considering the risk appetite levels for the enterprise, the following two major factors should be taken into account:
* The enterprise's objective capacity to absorb loss, e.g., financial loss, reputation damage, etc.
* The culture towards risk taking-cautious or aggressive. In other words, the amount of loss the enterprise wants to accept in pursue of its objective fulfillment.
D: Risk response process is triggered when the risk level increases the risk tolerance level of the enterprise, and not when it just equates the risk tolerance level.

The best way to protect company sensitive information from being exposed when an organization allows employee use of social media accounts for work purposes is to require employees to sign nondisclosure agreements. Nondisclosure agreements are legal contracts that prohibit the employees from disclosing or sharing the company sensitive information with unauthorized parties, such as competitors, media, or regulators. Nondisclosure agreements also specify the scope, duration, and conditions of the nondisclosure obligation, and the penalties or remedies for breaching the agreement. Requiring employees to sign nondisclosure agreements is the best way to protect company sensitive information, as it helps to prevent or deter the employees from exposing or leaking the company sensitive information on social media, and to hold the employees accountable and liable for their actions. Requiring employees to sign nondisclosure agreements also helps to comply with the legal and regulatory requirements for data protection and privacy. Educating employees on what needs to be kept confidential, implementing a data loss prevention (DLP) solution, and taking punitive action against employees who expose confidential data are also useful ways, but they are not as effective as requiring employees to sign nondisclosure agreements, as they are either dependent on the employees' awareness or behavior, or reactive or corrective measures, rather than proactive or preventive measures.

Awareness training is the most likely control that failed in this scenario, as it is designed to educate employees on the proper handling and protection of sensitive data, and the consequences of violating the organizational policy. Awareness training can help to prevent or reduce the occurrence of human errors, such as inadvertently removing a file from the premises, that may result in data loss or breach. The other options are not the most likely controls that failed, as they are either not directly related to the scenario or not sufficient to prevent the incident. Background checks are used to verify the identity, qualifications, and trustworthiness of potential or current employees, but they do not ensure that employees will always follow the policy or avoid mistakes. User access is used to restrict the access to information systems or resources based on the identity, role, or credentials of the user, but it does not prevent the user from copying or removing the data once they have access. Policy management is used to create, communicate, and enforce the organizational policy, but it does not ensure that employees will understand or comply with the policy.
