Time management techniques
Communication with team members

Good Answer Example:

I prioritize issues based on severity and impact on business operations. I use a ticketing system to categorize tickets by urgency and set up daily check-ins with my team to discuss high-priority cases. This way, I can quickly pivot and allocate resources efficiently based on current demands. I ensure that I communicate progress with both customers and stakeholders to set clear expectations.

Bad Answer Example:

I just deal with the tickets as they come in. I do my best to keep up.

Follow-up Questions:

Testing and confirming resolution

Good Answer Example:

Whenever I'm faced with a technical issue, the first step I take is actively listening to the user's description. I ask clarifying questions to pinpoint the issue precisely. Next, I check for common solutions in our knowledge base before applying any fixes. After implementing a solution, I perform testing to ensure the issue is fully resolved, and finally, I update our documentation to reflect the new information learned from the case.

Bad Answer Example:

I just try a few things until something works. If not, I ask someone else.

Follow-up Questions:

What tools do you reference for troubleshooting?
How do you ensure customer satisfaction during the process?

The OSI model is a seven-layer framework that standardizes communications in a network. The layers are: 1) Physical, 2) Data Link, 3) Network, 4) Transport, 5) Session, 6) Presentation, and 7) Application. Each layer serves its own purpose, and they work together to enable network connectivity. For example, the Transport layer is crucial for ensuring complete data transfer, notably using protocols like TCP and UDP.

Resolving hardware/software conflicts

Good Answer Example:

To troubleshoot a non-connecting printer, I would start by ensuring that the printer is powered on and properly connected to the network. Next, I would check the printer's display for error messages. I’d also verify that the computer is connected to the same network as the printer. If needed, I would attempt to ping the printer’s IP address. Lastly, I’d reinstall the printer drivers and check the print spooler service to ensure it’s running.

Tools to Mention:

Ping commands Printer configuration interface Driver installation programs Network settings

Advanced Technical Questions

Q: Can you explain how to secure a network?

Expected Knowledge:

Good Answer Example:

Network security can be secured through a combination of strategies: using firewalls to block unauthorized access, implementing VPNs to encrypt sensitive communications, and ensuring robust antivirus software is in place. I also advocate for strong password policies, regular software updates, and educating users about phishing attacks. Access controls like role-based permissions further safeguard sensitive areas and limit exposure to threats.
