This question is an opportunity to show your knowledge of encryption and how you apply it in your work. You can describe a specific situation where you used encryption algorithms or protocols, the steps you took to implement them and the results you achieved. Troubleshooting is a major part of being an engineer, and employers ask linux network engineer this question to see if you have experience with it. Wireless networks are a common way to connect devices, and the interviewer may want to know how you would secure them. Give examples of your methods for securing wireless connections and what steps you take to ensure they’re safe from outside interference or hacking attempts.

Knowing how you approach debugging and resolving problems will also help the interviewer gauge your problem-solving skills. Many Linux engineering roles require working in the command line environment, so interviewers want to be sure that you’re comfortable with this type of work. Knowing how to navigate the command line is a critical skill for Linux engineers, and your answer to this question will determine whether or not you’re the right fit for the job.

The pkill command sends a signal (by default, SIGTERM) to the matched processes, causing them to terminate. To compress files in Linux, you can use the tar command along with gzip compression. The /etc/resolv.conf is the config file used for the DNS server resolution process. This config file is used to specify the DNS server, set up the search directive for domains, and configure the resolver options. The full form of LVM is Logical Volume Manager, which provides an advanced disk management approach in Linux.
