Incident Response and Troubleshooting Questions
Approach to diagnosing and resolving production incidents, outages, and critical failures under time pressure. Covers systematic triage, identifying root causes, maintaining service availability, coordinating with stakeholders, prioritizing safety and mitigation steps, postmortem practices, and learning from incidents to prevent recurrence. Interviewers expect examples showing technical troubleshooting, communication during crises, decision making under pressure, and follow through in remediation and documentation.

Case study: Executives ask whether to spend $3M to implement active-active, multi-region high-availability for a critical service versus investing $500k to build robust incident-response automation, runbooks, and an expanded on-call team. As the Systems Administrator leading the ops analysis, outline the factors you would evaluate, quantitative measures (expected downtime costs, probability of failure, MTTR improvements), and how you would present a recommendation with risk tolerances.

After a high-severity outage where multiple dependent services failed and initial logs were insufficient to identify a clear root cause, outline an investigative plan to reconstruct the incident timeline, validate competing hypotheses, gather ephemeral data that may no longer be available, and produce an actionable postmortem. Include how to involve cross-team subject matter experts and how to surface evidence gaps.

Explain how you would prioritize simultaneous incidents that affect different services (e.g., email outage vs. low-level log loss for a non-critical service). Describe the criteria you use (business impact, number of users affected, regulatory constraints, SLOs), how you document priorities, and how you allocate limited on-call resources.

A critical production database shows logical corruption limited to a subset of user records while underlying storage appears healthy. As the Systems Administrator responsible for recovery, outline in detail how you would contain the issue, perform forensic analysis, perform selective restoration to minimize data loss, verify data integrity post-restore, and communicate with legal/compliance and impacted stakeholders.

Explain how service-level objectives (SLOs) and service-level indicators (SLIs) should influence incident prioritization and escalation for a Systems Administrator. Provide examples that show when a violation requires immediate escalation and when an issue can be handled as part of routine maintenance.
