正解:A
The organization's risk tolerance is the most important factor to consider when choosing a shared alternate location for computing facilities, as it determines the acceptable level of risk exposure and the required recovery time objective (RTO) for the organization. A shared alternate location is a facility that is used by multiple organizations for disaster recovery purposes, and it may have limited resources, availability, and security. Therefore, the organization must assess its risk tolerance and ensure that the shared alternate location can meet its recovery requirements and protect its information assets.
