IT Support Technical Specialist Interview Questions and Answers
1. How do you approach troubleshooting a system that is randomly rebooting?
Answer:
I begin by checking hardware diagnostics, RAM, hard disk, and temperature monitoring, to rule out physical faults. Then I examine system logs (Event Viewer on Windows or syslog on Linux/macOS) for critical error codes or unexpected shutdown messages. I also verify driver and BIOS/firmware versions, check for recent updates, and test power supply stability. If needed, I use tools like MemTest86 or PSU testers for hardware-level isolation.
2. What steps do you follow when users report that shared files on the network are no longer accessible?
Answer:
First, I verify the user’s network connectivity and try to reproduce the issue from another device. Then I check DNS resolution and ensure the file server is reachable via IP and hostname. I examine user permissions on the shared folder, inspect Active Directory group memberships if relevant, and confirm that no recent changes were made to mapped drives or GPOs. If multiple users are affected, I also check for file server outages, storage issues, or locked files.
3. What’s your process for diagnosing performance issues on a user’s workstation?
Answer:
I start by gathering system information, CPU, memory, and disk usage, using Task Manager or Resource Monitor. I look for background processes causing high resource consumption and check for malware using endpoint protection tools. I also examine Windows Updates, driver versions, and boot time using tools like Autoruns. If performance lags persist, I check for hardware wear such as SSD degradation or thermal throttling, and run stress tests if needed.
4. How do you troubleshoot DNS resolution issues?
Answer:
I start by running nslookup or dig to confirm whether the issue is with name resolution or connectivity. I then check the local DNS cache (ipconfig /displaydns) and try flushing it. If that fails, I test using an external DNS (e.g., 8.8.8.8) to rule out internal DNS server issues. I verify the correct DNS servers are assigned (via DHCP or static), and examine firewall rules that might be blocking DNS traffic. I also inspect DNS logs on the server side if internal zones are affected.
5. How do you deploy and manage software updates across a large fleet of endpoints?
Answer:
I use centralized endpoint management platforms like Microsoft Intune, WSUS, or SCCM for Windows environments, and JAMF or Munki for macOS. I create update rings or deployment groups based on criticality, and test patches in a staging environment before broad rollout. I monitor update status and compliance reports and use PowerShell or bash scripts for handling exceptions. Scheduled deployments are coordinated to minimize user disruption.
6. What is your method for identifying and resolving network latency issues?
Answer:
First, I confirm the latency using ping, tracert, or mtr tools. I check for packet loss, high hops, or unusual delays. I isolate whether the issue is internal (LAN/Wi-Fi congestion, duplex mismatch, faulty switches) or external (ISP, routing). I examine switch logs, bandwidth usage on firewalls, and QoS policies. If wireless is involved, I assess signal interference or overcrowding using tools like NetSpot or WiFi Analyzer. I also test alternate paths if SD-WAN or VPNs are in use.
7. How do you support cross-platform authentication in a mixed environment (Windows, macOS, Linux)?
Answer:
I use Active Directory with LDAP/LDAPS integration for non-Windows systems. For macOS, I configure AD binding or use enterprise mobility tools like JAMF. For Linux, I configure SSSD or Kerberos with AD support. Centralized authentication ensures consistency in user management. I also enforce consistent password policies and use identity federation tools (e.g., Azure AD or Okta) where applicable for SSO across apps and systems.
8. How do you handle disk space alerts on a critical production server?
Answer:
I quickly identify large files using command-line tools (du, TreeSize, etc.) or GUI tools. I check for log file growth, failed backups, or old snapshots. I safely clean temporary files or rotate logs if applicable. For Windows servers, I may also clear Windows Update caches and shadow copies. If space cannot be recovered, I either extend the disk volume or migrate services to a larger partition. I also set up monitoring alerts to prevent future surprises.

I confirm the user’s internet connectivity, then check service status via public dashboards (e.g., status.office.com). I verify the user’s login credentials, browser settings (cookies, cache, extensions), and network restrictions like blocked ports or proxies. I review SSO configurations if used, and inspect identity provider logs for failed login attempts. If the issue is account-specific, I reset the user’s session or permissions. I document the root cause and communicate clearly with the user.
10. How do you secure endpoints in an enterprise environment?
Answer:
I implement multiple layers of protection:
- Endpoint Detection and Response (EDR) like CrowdStrike or Defender for Endpoint
- Regular OS and application patching
- Hardening policies via GPO or device management tools
- Full disk encryption (BitLocker, FileVault)
- Restricting admin privileges and enforcing least privilege
- Security awareness training to mitigate social engineering
Monitoring, incident logging, and integrating with SIEM platforms help ensure compliance and rapid threat response.
