During a disaster recovery test, an IS auditor observes that the performance of the disaster recovery site`s server is slow. To find the root cause of this, the IS auditor should FIRST review the: 

Answer options:

A. event error log generated at the disaster recovery site.
B. disaster recovery test plan.
C. disaster recovery plan (DRP).
D. configurations and alignment of the primary and disaster recovery sites.

D

Since the configuration of the system is the most probable cause, the IS auditor should review that first. If the issue cannot be clarified, the IS auditor should then review the event error log. The disaster recovery test plan and the disaster recovery plan (DRP) would not contain information about the system configuration.
