7 Windows Administrator Interview Questions and Answers

Introduction

This question is crucial for assessing your technical troubleshooting skills, which are essential for a Junior Windows Administrator role. Understanding how to diagnose performance issues is a key responsibility in maintaining server health.

How to answer

• Start by outlining the initial steps you would take, such as checking resource utilization (CPU, memory, disk I/O)
• Discuss the tools you would use, like Task Manager or Performance Monitor
• Explain how you would analyze logs for errors or warnings
• Mention any common performance bottlenecks in Windows environments
• Conclude with how you would implement a solution and monitor the server post-fix

What not to say

• Being vague about troubleshooting steps or tools
• Failing to mention any systematic approach to diagnosing issues
• Ignoring the importance of monitoring after a fix
• Overly complicating the answer without clear reasoning

Example answer

“If a Windows server is running slowly, I would first check the Task Manager to identify any processes consuming excessive CPU or memory. I would use Performance Monitor to track resource usage over time. If I notice high disk I/O, I would check for any running backups or antivirus scans. After identifying the bottleneck, I would either close unnecessary applications or adjust the resource allocations. Finally, I would monitor the performance after the fix to ensure stability.”
