41 practice questions · Last updated on Aug 25, 2026

Q&A guide Share:

IT operations interviews test process discipline as much as technical knowledge. Expect questions on the difference between an incident, a problem and a change, RTO and RPO and how they drive backup design, RAID levels and why RAID is not backup, troubleshooting a slow server or network, Active Directory and Group Policy, patch management and hardening, and monitoring and alerting practice. Incident communication and blameless postmortems feature prominently. The questions below cover both sides.
