CompTIA Network Plus N10-009 Certification Exam Study Session - September 2026

This is a September 2026 live stream study session for the CompTIA Network Plus N10-009 certification exam, hosted by Professor Messer from Orlando, Florida. The N10-009 exam consists of 90 questions over 90 minutes with a passing score of 720 on a scale of 100 to 900, and the certification is expected to remain current until the end of 2027. The session covers multiple-choice and performance-based questions directly from the official CompTIA exam objectives, including topics on routing behavior when packets lack destination routes, DNS zone file records, and firewall configuration for various network services. Key technical content includes explanations that routers drop packets when no route exists and send ICMP host unreachable messages to the source address, the Start of Authority (SOA) record contains serial numbers and retry intervals for DNS zone updates, and specific port numbers for services like SSH (port 22), RDP (port 3389), SIP (ports 5060 and 5061), DNS (port 53), SNMP (ports 161 and 162), and SMB (port 445). The instructor emphasizes understanding not just port numbers but the actual function and use cases of network services, as exam questions require applied knowledge rather than simple memorization.
