What is your approach to UNIX administration?

There are a few reasons an interviewer might ask this question:

1. To gauge the candidate's depth of knowledge - a good administrator will have a solid understanding of the underlying system, not just be able to follow a recipe.

2. To see if the candidate is proactive or reactive - a proactive administrator will be constantly looking for ways to improve the system, while a reactive one will only make changes when something breaks.

3. To find out if the candidate is familiar with best practices - a good administrator will be up-to-date on the latest best practices and be able to explain why they are important.

4. To determine if the candidate is a team player - a good administrator will be able to work well with others, sharing knowledge and ideas.

Example: “My approach to UNIX administration is to always keep the system up to date with the latest security patches and updates. I also regularly check the system logs for any unusual activity. In addition, I have a good backup plan in place in case of any system failure.”

What are some of the challenges you have faced in administering UNIX systems?

Some of the challenges that an interviewer might ask about administering UNIX systems include:

-How to effectively manage user accounts and permissions

-How to deploy updates and patches across a fleet of servers

-How to monitor system performance and identify potential bottlenecks

-How to troubleshoot common issues that can occur on UNIX systems

Asking about these challenges helps the interviewer to gauge the candidate's level of experience and knowledge in administering UNIX systems. It also allows the interviewer to get a better understanding of the candidate's problem-solving abilities.

Example: “There are a number of challenges that can arise when administering UNIX systems. One common challenge is managing user accounts and permissions. It is important to ensure that only authorized users have access to the system, and that they have the appropriate level of access for their needs. Another challenge is keeping the system up to date with security patches and software updates. This can be a time-consuming process, but it is essential to keeping the system secure. Additionally, troubleshooting issues that arise can be challenging, as there may be a number of potential causes. However, with experience and knowledge, these challenges can be overcome.”

What are some of the best practices you have adopted in administering UNIX systems?

The interviewer is asking the administrator about the best practices they have adopted in administering UNIX systems in order to gauge their level of experience and expertise. It is important for the interviewer to know what best practices the administrator has adopted in order to determine if they are qualified for the position.

Example: “There are many best practices that can be adopted when administering UNIX systems, but some of the most important ones include:

1. Keep the system up to date: Make sure to keep the system software and all user-installed software up to date. This can be done by regularly running package managers such as yum or apt-get, or by manually checking for and installing updates.

2. Harden the system: Take steps to secure the system against potential attacks, such as setting up a firewall, configuring security settings in applications, and using strong passwords.

3. Monitor system activity: Use tools like top, ps, and netstat to monitor system activity and identify potential issues early on.

4. Keep good backups: Regularly backing up data is essential in case of data loss or corruption. Be sure to use a reliable backup solution and test restores periodically to ensure that the backups are working as expected.”

What is your experience in managing user accounts and permissions in UNIX?

The interviewer is asking about the candidate's experience in managing user accounts and permissions in UNIX because it is an important part of the administrator's job.
