What is the greatest concern an IS auditor should have during a review of a disaster recovery hot site?

The greatest concern during a review of a disaster recovery hot site is related to how well the disk space utilization data is kept current. Accurate and up-to-date disk space utilization data is crucial for maintaining proper functionality and ensuring that the systems can effectively handle the recovery process when needed. If this data is not current, it can lead to several issues such as inefficient resource allocation, difficulty in managing workloads, or even critical system failures during an actual disaster recovery scenario.

Maintaining current disk space utilization data ensures that there is enough capacity to restore operations smoothly without interruptions. It also aids in the planning for additional resources if needed, allowing for timely decisions regarding the acquisition of further storage or adjustments to the disaster recovery plan.

In the context of disaster recovery, timely and accurate data is essential for the success of recovery efforts. Therefore, an IS auditor should prioritize this aspect as it directly impacts the effectiveness of the disaster recovery site. The other options, while they might pose concerns, do not directly impact the immediate operational readiness and resource management as significantly as outdated disk space utilization data does.
