  Answer: I would immediately report the incident to the relevant authorities and initiate containment measures to prevent any further damage. I would also work with our company's IT security team to identify the root cause of the breach, implement necessary security updates, and conduct a thorough review of our protocols and procedures to prevent future incidents.
• 4. Imagine you are working on a large-scale database migration project. How would you ensure a smooth and successful transition?
  Answer: I would first analyze the current database structure and data to determine the most efficient and secure method for migration. Next, I would work closely with the development team to ensure proper testing and validation before the launch.
