Which of the following is MOST important in determining whether a disaster recovery test is successful?
A. Only business data files from offsite storage are used
B. IT staff fully recovers the processing infrastructure
C. Critical business processes are duplicated
D. All systems are restored within recovery time objectives (RTOs)
Correct Answer: C
Explanation/Reference:
To ensure that a disaster recovery test is successful, it is most important to determine whether all critical business functions were successfully recovered and duplicated. Although ensuring that only materials taken from offsite storage are used in the test is important, this is not as critical in determining a test’s success.
While full recovery of the processing infrastructure is a key recovery milestone, it does not ensure the success of a test. Achieving the RTOs is another important milestone, but does not necessarily prove that the critical business functions can be conducted, due to interdependencies with other applications and keyelements such as data, staff, manual processes, materials and accessories, etc.
