Technical Knowledge
A user called in reporting that their desktop would not power on after a recent power outage.
Identify the root cause and restore the workstation to operational status.
First, verified the power cable was securely connected, then tested the outlet with a known‑good device. Checked the power supply unit for signs of failure, listened for beep codes, and inspected internal components for loose connections. If hardware was intact, I attempted to boot into safe mode and ran hardware diagnostics.
Discovered a faulty power supply, replaced it, and the PC booted normally within 30 minutes, minimizing downtime.
- What would you do if the PC still wouldn't start after checking the power supply?
- How do you document the troubleshooting steps?
- Which tools do you use for hardware diagnostics?
- Systematic approach
- Safety precautions
- Clear communication with user
- Timely resolution
- Skipping basic power checks
- Ignoring beep codes
- Failing to document actions
- Check power cable and outlet
- Listen for beep codes or POST messages
- Test power supply unit
- Inspect internal connections
- Attempt safe‑mode boot and run diagnostics
- Replace faulty component and verify functionality
An employee reported suspicious pop‑ups and sluggish performance on their Windows 10 laptop.
Contain the infection, remove malicious software, and prevent future incidents.
Isolated the laptop from the network, ran a full offline scan with the corporate antivirus, identified and quarantined the malicious files, applied the latest OS patches, and reset the user’s passwords. Documented the incident in the ticketing system and updated the security awareness log.
The workstation was clean and restored within two hours, and the employee received a brief security refresher, reducing repeat incidents.
- What steps would you take if the malware persisted after the initial scan?
- How do you ensure the user’s data is not lost?
- Which logs do you review for forensic evidence?
- Prompt containment
- Effective removal of malware
- User communication
- Accurate documentation
- Delaying isolation
- Using unapproved removal tools
- Neglecting to reset passwords
- Isolate the device from network
- Run full offline antivirus scan
- Quarantine/remove malicious files
- Apply OS and software patches
- Reset compromised credentials
- Document incident and actions
Customer Service
A user was frustrated because their email client kept crashing during a critical client presentation.
Calm the user, resolve the email issue quickly, and ensure the presentation could proceed without interruption.
Listened actively to the user’s concerns, apologized for the inconvenience, and offered an immediate workaround by switching to the web client. Simultaneously, I investigated the desktop logs, identified a corrupted Outlook profile, and recreated it while the user continued with the web client. Kept the user updated throughout the process.
The user completed the presentation without further issues, and the Outlook client was fully functional afterward. The user expressed appreciation for the swift resolution and clear communication.
- How do you handle repeated complaints from the same user?
- What if the temporary workaround isn’t viable?
- Empathy and active listening
- Speed of resolution
- Clear communication
- Effective technical fix
- Blaming the user
- Taking too long to provide a workaround
- Acknowledge user frustration and apologize
- Provide immediate temporary solution
- Diagnose root cause (corrupted profile)
- Implement fix while user works on workaround
- Communicate progress and confirm resolution
At the start of a shift, I received a backlog of ten tickets ranging from password resets to network outages.
Determine the order of work to address the most critical issues first while maintaining service level agreements.
Applied a triage matrix: classified tickets by impact (number of users affected) and urgency (business-critical deadlines). Resolved high‑impact network outage first, then handled password resets for VIP users, followed by lower‑priority software install requests. Communicated expected wait times to all requestors and updated ticket statuses regularly.
The network outage was resolved within 45 minutes, minimizing downtime for 200 users. All tickets were closed within the SLA, and user satisfaction scores improved by 12% that week.
- What criteria would you adjust if a ticket from a senior executive arrives?
- How do you handle tickets that have the same impact and urgency?
- Logical prioritization
- Adherence to SLA
- Transparent communication
- Efficient ticket closure
- Ignoring impact/urgency
- Lack of communication
- Assess impact and urgency of each ticket
- Use a triage matrix or SLA guidelines
- Address high‑impact/urgent tickets first
- Communicate timelines to users
- Monitor and adjust as new tickets arrive
Problem Solving
Our company expanded to three new remote offices, and employees needed secure access to internal Windows servers.
Design and deploy a scalable remote desktop solution that meets security and performance requirements.
Evaluated options (VPN + RDP, RD Gateway, and third‑party SaaS). Chose an RD Gateway with multi‑factor authentication for secure tunneling. Configured server farms, set up group policies for access rights, and created user training documentation. Conducted pilot testing with a small group before full rollout.
All remote users gained reliable, secure desktop access within two weeks, with zero security incidents reported during the first month and a 15% increase in remote productivity metrics.

- Pilot test and gather feedback
- Roll out company‑wide with documentation
All employees reported that the floor‑2 network printer was showing 'offline' in their print queues.
Diagnose the cause and restore printing services for the entire floor.
Checked the printer’s status panel—found a blinking error light indicating a paper jam. Cleared the jam, performed a hard reset, and verified the printer’s IP address was unchanged. Confirmed connectivity by pinging the printer from a workstation. Updated the printer driver on the print server and communicated the resolution to users via a broadcast message.
Printing resumed within 15 minutes, and no further complaints were received. Updated the maintenance log to prevent future jams.
