  I make sure to double-check my work and use tools such as syntax checkers and debugging environments to identify any potential errors. I also regularly review my work with team members for feedback and incorporate their suggestions.
• 15. How do you handle a situation where a task or project is taking longer than anticipated?
  I keep stakeholders informed about delays and the reason behind them, and work with them to determine a new timeline and prioritize tasks accordingly. I also reflect on the delay and identify any areas where I could improve my time management or processes for future projects.

Situational Questions

• 16. What would you do if an AIX server became unresponsive during peak hours with critical applications running on it?
  I would first check for any obvious hardware or software issues and attempt to restart the server if feasible. If the server remains unresponsive, I would escalate the issue to the relevant team and inform stakeholders about the potential impact and progress of the resolution.
• 17. Imagine you need to upgrade an application on an AIX server, but the developers insist on using a specific version that is known to have compatibility issues. How would you handle this situation?
  I would first communicate the potential risks and impact of using the specific application version to the developers. If they still insist on using it, I would test and isolate the application to minimize any potential issues and collaborate with the developers to resolve any issues that may arise.
• 18. How would you handle a security breach or unauthorized access to an AIX server?
  I would follow the established security protocols and isolate the compromised server to prevent further damage. I would then review access logs and investigate the source of the breach and take necessary actions, such as resetting passwords and implementing additional security measures, to prevent future breaches.
• 19. Imagine a situation where you need to make a critical change on an AIX server, but there is no time for thorough testing. How do you handle this?
  I would communicate the potential risks and impact of the change to stakeholders and get their approval to proceed with the change in a controlled environment. I would also document the change and closely monitor the server for any potential issues, and have a rollback plan in case of any major problems.
• 20. How do you handle a situation where an AIX server crashes or goes down during a critical system update?
  If the server crash occurred due to the update, I would first roll back the update and isolate the server to prevent further issues. I would then work with my team to identify the cause of the crash and determine the best course of action to bring up the server and minimize the impact on the system.
