Walk me through how you’d troubleshoot a laptop that suddenly can’t connect to Wi‑Fi while others in the office are fine.
Employers ask this question to see your troubleshooting methodology and ability to quickly isolate variables. In your answer, show a logical flow from basic checks to deeper diagnostics, and mention both OS tools and network concepts you’d use.
Answer Example: "I start by confirming the scope: is it just this device and just Wi‑Fi? I check the adapter status, toggle Wi‑Fi, and forget/rejoin the SSID, then verify IP/DHCP and DNS via ipconfig/ifconfig and nslookup. Next I look at drivers and recent updates, check event logs, and test another network to rule out AP or RADIUS issues. If needed, I reassociate the device in the MDM, reset network settings, and coordinate with the network team if I see MAC filtering or 802.1X auth failures."

Tell me about a time you handled a high‑priority outage that impacted multiple users. How did you communicate and resolve it?
Employers ask this to gauge your incident management skills under pressure and your customer communication style. In your answer, highlight quick triage, clear updates, collaboration, and post‑incident follow‑through.
Answer Example: "At my last company, a VPN cert issue prevented logins for the entire sales team. I immediately posted a status update with an ETA, created a bridge with network/security, and offered a temporary split‑tunnel workaround. We rolled back a faulty cert, restored access within 35 minutes, and I published a brief post‑mortem with action items to prevent recurrence."

Can you explain DNS in plain terms and how you’d troubleshoot name resolution issues?
Employers ask this to see your understanding of core networking and your ability to explain it to non‑technical users. In your answer, cover the basics and concrete troubleshooting steps.
Answer Example: "DNS is the phonebook of the internet, translating names to IP addresses. I’d test with nslookup/dig, check local hosts file, verify DHCP DNS settings, and try an alternate resolver like 8.8.8.8 to isolate the issue. If it’s internal, I’d check split DNS, VPN settings, and whether the domain is resolving on the internal DNS servers."
