The correct answer is:
A. Lead a simulated failover.
Explanation:
A simulated failover is the best way to validate the integrity and availability of a disaster recovery (DR) site. This involves performing a controlled test where the operations of the primary site are intentionally interrupted (e.g., simulating a failure), and the DR site is activated to take over the workload. This ensures that the DR site is capable of handling operations as expected, providing both availability (ensuring services can continue in the event of a failure) and integrity (confirming the site has the correct, intact data and configurations).
A simulated failover involves testing the disaster recovery (DR) site by simulating an actual disaster scenario, where the primary site goes down, and the systems are brought up at the DR site. This test validates both the integrity (ensuring data is intact and correctly recovered) and availability (ensuring the DR site can take over operations smoothly) of the DR site. It’s the most effective way to ensure that the DR site will function properly during an actual disaster.
NOT B. Conduct a tabletop exercise: A tabletop exercise is a discussion-based activity where team members go over the steps they would take in the event of a disaster. While valuable for training and planning, it doesn't validate the actual functionality of the DR site or systems. It's more focused on procedural readiness.
I guess it is B: A tabletop exercise is a valuable tool for testing your disaster recovery plan in a controlled setting. During this exercise, key stakeholders gather around a table to discuss and strategize how they would respond to a hypothetical disaster scenario. This exercise allows participants to identify gaps in their plan, refine communication channels, and assess decision-making processes. This exercise is the easiest to set up as it takes the least administrator effort as it is a paper-based exercise.
A simulated failover is the best way to validate the integrity and availability of a disaster recovery site. It involves simulating a real-world disaster and switching over to the backup site. This allows organizations to test their disaster recovery plan and identify any potential issues or weaknesses
