Disaster Recovery

Correct Answer: Uninterruptible Power Supply (UPS)

In the context of power disruptions, the most effective disaster recovery solution would be to install an Uninterruptible Power Supply (UPS). A UPS guarantees that power is uninterrupted during outages by providing immediate, short-term power to all devices connected to it. This is important because it allows the systems to remain operational until a more permanent power solution is restored. On the other hand, the other options are less viable. Redundant internet connections can provide backup in case of internet failure, but it doesn't solve power outage problems. Installing additional network switches can improve network performance and provide redundancy, but it also doesn't solve the issue of a power outage. Lastly, moving servers to a safer location addresses threats like natural disasters or physical harm, not power disruptions.

Correct Answer: Implement a High Availability Cluster

The best solution to minimize downtime during a disaster recovery situation is to 'Implement a High Availability Cluster'. High availability clustering is a method of distributing an application's data across a cluster of redundant nodes. The goal is to ensure that services remain available in the event of a nightmare scenario and increase system reliability. Now, let's look at why the other answers are incorrect: 'Schedule Mandatory Employee Training' can indeed improve overall system use and reduce human error, but it won't necessarily reduce downtime during a disaster. 'Install Video Surveillance Systems' can improve security but again, has little effect on downtime during a disaster recovery situation. 'Decrease Backup Frequency' is not advisable because it actually risks increasing downtime. It would lead to more data loss because backups would not be as current, making recovery after a disaster even more lengthy and challenging.

Correct Answer: Simulate a Disaster and Test the Recovery Procedures

The best method to validate a company's disaster recovery plan is to 'Simulate a Disaster and Test the Recovery Procedures'. This will provide the most realistic scenario and will test both the technical aspects of the recovery plan and the team's ability to execute the plan under stress. Hiring an external consultant only provides an outside perspective but does not test the plan in action. Increasing the frequency of backups might be part of a disaster recovery plan, but it doesn't test the effectiveness of the full plan. Conducting a security audit is more related to preventative measures, not responding to a disaster.
