Final answer:
BIA serves as the foundation for a site risk assessment, contingency reaction plan, resumption assessment plan, and functional recovery plan within business continuity planning. Thus all the options are correct.
Step-by-step explanation:
A Business Impact Analysis (BIA) is critical in developing a comprehensive contingency and recovery plan for organizations. A BIA can be the foundation for several components within business continuity planning:
Site risk assessment: The BIA helps assess risks to business operations, which is essential in identifying and mitigating potential threats at a specific location.
Contingency reaction plan: It uses the data from a BIA to prepare for immediate actions in the event of an incident to ensure that critical business functions continue with minimal interruption.
Resumption assessment plan: The BIA informs this plan by identifying the time-critical functions that need to be resumed to maintain business viability.
Functional recovery plan: It outlines the steps to restore business operations to normal levels after an incident; BIA guides the recovery priorities and strategies.
Therefore, the correct answers are: Site risk assessment, Contingency reaction plan, Resumption assessment plan and Functional recovery plan.
