Professor Messer CompTIA Network Plus N10-009 Study Group - October 2026 Session
This is the October 2026 Professor Messer CompTIA Network Plus N10-009 study group session, a monthly live stream where participants answer practice exam questions. The N10-009 exam was released in June 2024 and is estimated to retire around the end of 2027, requiring a passing score of 720 on a scale of 100 to 900 with a maximum of 90 questions in 90 minutes. The session covers both multiple-choice and performance-based questions, with the performance-based question of the month focusing on identifying network troubleshooting commands including ipconfig, arp -a, traceroute, nslookup, tcpdump, and netstat based on their output. Questions covered DNS zone file records including the SOA (Start of Authority) record which contains serial numbers and retry interval information, quality of service (QoS) for prioritizing VoIP traffic over database backups, and identifying access points using BSSID among other network identifiers. The instructor streams at 1080p resolution with approximately 10-15 seconds of latency to YouTube, sending data at approximately 5.95-5.96 Mbps, and mentions having a 2 gigabit up and down connection with a 5G cellular backup providing 50-100 Mbps.
