Avoidance is a risk response strategy that involves eliminating the threat or uncertainty associated with a risk by removing the cause or the source of the risk. Avoidance can help to prevent the occurrence or the impact of a negative risk, but it may also result in the loss of potential opportunities or benefits. Avoidance is usually applied when the risk is too high or too costly to mitigate, transfer, or accept12
The business analyst is using the avoidance strategy by decommissioning the server that has a vulnerability. By doing so, the analyst is eliminating the possibility of the vulnerability being exploited or causing harm to the system or the data. However, the analyst is also losing the functionality or the value that the server provides, and may need to find an alternative solution or resource.
Mitigation is not the correct answer, because mitigation is a risk response strategy that involves reducing the probability or the impact of a negative risk by implementing actions or controls that can minimize or counteract the risk. Mitigation can help to lower the exposure or the severity of a risk, but it does not eliminate the risk completely. Mitigation is usually applied when the risk is moderate or manageable, and the cost of mitigation is justified by the potential benefit12
Transference is not the correct answer, because transference is a risk response strategy that involves shifting the responsibility or the impact of a negative risk to a third party, such as a vendor, a partner, or an insurer. Transference can help to share or distribute the risk, but it does not reduce or remove the risk. Transference is usually applied when the risk is beyond the control or the expertise of the organization, and the cost of transference is acceptable or affordable12
Acceptance is not the correct answer, because acceptance is a risk response strategy that involves acknowledging the existence or the possibility of a negative risk, and being prepared to deal with the consequences if the risk occurs. Acceptance can be passive, which means no action is taken to address the risk, or active, which means a contingency plan or a reserve is established to handle the risk. Acceptance is usually applied when the risk is low or inevitable, and the cost of avoidance, mitigation, or transference is higher than the cost of acceptance12
