I would validate DNS resolution with the appropriate tools, compare results to expected records, then test network connectivity to the resolved IP and relevant port. I would document each result and escalate with packet captures or logs if the evidence points to a broader DNS, firewall, or application issue. Explain the TCP three-way handshake and why it matters in support troubleshooting. A client begins with SYN, the server responds with SYN-ACK, and the client completes the connection with ACK. Failures at any stage can indicate routing, firewall, load balancer, service availability, or packet-loss issues. Understanding the handshake helps isolate whether a problem occurs before application-layer communication begins. Describe how you would handle a complex issue that is outside your current expertise. I would acknowledge the issue, gather the required environment details, logs, timestamps, and reproduction steps, and follow established troubleshooting documentation. I would communicate clear expectations to the customer, engage the appropriate senior engineer or cross-functional team, and remain accountable for updates. After resolution, I would record the learning and contribute useful details to the knowledge base. What information should a high-quality support ticket update include? It should state the customer impact, actions taken, observed results, relevant logs or error messages, current hypothesis, next steps, ownership, and expected update time. The update should be technically accurate while remaining understandable to the customer and internal stakeholders. Clear documentation prevents duplicated work and supports efficient escalation. How would you explain a TLS certificate error to a non-technical customer? I would explain that TLS is the security check used to confirm the service is legitimate and protect data in transit. A certificate error means the browser or system cannot fully verify that security check, often because the certificate is expired, does not match the service name, or is missing a trusted chain. I would then give concise, safe next steps while collecting the certificate details needed for investigation. At ExtraHop, we’re on a mission to protect and empower the connected enterprise.
