Interview Questions

These are some interview questions (the ones I could remember), which I received while interviewing for DevOps roles.

  • What’s a PTR in DNS?
  • What’s a MX record in DNS?
  • Difference between RAID 1 and 5?
  • What’s the advantage of one RAID over another?
  • Alternative to init.d in Linux?
  • How to view running processes in Linux?
  • Difference between authorization and authentication?

Common sense: any question that could be answer by Google in 5 seconds should not be used to test any one.
