Which of the following is the BEST method for determining the criticality of each application system in the production environment? 

Answer options:

A. interview the application programmers.
B. Perform a gap analysis.
C. Review the most recent application audits.
D. Perform a business impact analysis.

D

A business impact analysis will give the impact of the loss of each application. Interviews with the application programmers will provide limited information related to the criticality of the systems. A gap analysis is only relevant to systems development and project management. The audits may not contain the required information or may not have been done recently.
