Example: “I understand the importance of backing up cloud servers and ensure that I do it on a regular basis. As a Cloud Administrator, I make sure to back up my cloud servers at least once a week. This ensures that if anything were to happen to the server, I would have recent data available for recovery.

In addition to weekly backups, I also perform monthly full system backups. These full system backups are stored in an offsite location so that they can be recovered in case of any major disaster or issue with the primary server. I also use version control software to track changes made to the server over time. This allows me to easily roll back to a previous version should something go wrong.”

17. There is a bug in the code you wrote. How do you handle it?

This question is a great way to test your problem-solving skills. It also shows the interviewer how you handle mistakes and learn from them. Your answer should show that you are willing to take responsibility for your actions, even if they lead to errors in coding.

Example: “When I encounter a bug in the code I wrote, my first step is to assess the severity of the issue. If it’s a minor bug that doesn’t affect system performance or user experience, I’ll document the issue and prioritize it for later resolution. However, if the bug is more serious and has an immediate impact on system performance or user experience, I will take steps to quickly identify and fix the problem.

To do this, I will review the source code and debug logs to determine what caused the bug and how best to address it. Then, I will create a plan to resolve the issue, which may include updating existing code, writing new code, or making changes to the environment. Finally, I will test the solution to ensure that the bug is resolved and no other issues have been introduced.”

18. How would you go about testing a new cloud application?

This question can help the interviewer assess your technical skills and how you apply them to a job. Use examples from past experience in which you used testing tools or methods to ensure applications functioned properly before deploying them to clients.

Example: “Testing a new cloud application is an important step in ensuring that the application will function properly and securely. My approach to testing a new cloud application would involve several steps.

The first step I would take is to review the application’s architecture and design, making sure that it meets all security requirements and best practices for cloud applications. This includes reviewing access control policies, authentication methods, encryption protocols, and other security measures. Once I am satisfied with the security of the application, I would move on to performance testing.

Performance testing involves running tests to measure the application’s responsiveness and scalability. During this process, I would use tools such as load testing software to simulate user traffic and see how the application responds under different conditions. I would also monitor resource usage during these tests to ensure that the application does not exceed its allocated resources.

Once I have completed performance testing, I would then move on to functional testing. This involves testing the application’s features and functionality to make sure they are working correctly. Finally, once all tests have been successfully completed, I would deploy the application into production.”
