June 2026 Professor Messer N10-009 Network+ Study Group Session Overview

The video is a June 2026 Professor Messer N10-009 Network+ study group live session focused on CompTIA Network+ exam preparation, covering interactive questions directly from the exam objectives. The session includes a rewind question about troubleshooting a workstation-switch connection issue, where a speed mismatch (1 Gbit vs. 100 Mbit) was identified as the cause of an unlit physical link light. A performance-based question demonstrated firewall rule interpretation, requiring participants to determine whether traffic flows (e.g., TCP 443, TCP 22) would be allowed or denied based on a stateful firewall rule set with an implicit deny. The session also addressed an OSI model question, confirming that a switch’s port determination occurs at Layer 2 (Data Link Layer). Additional details included exam logistics: 90 minutes, up to 90 questions, passing score of 720/900, with performance-based questions potentially offering partial credit. The Network+ exam version discussed (N10-009) was released on June 20, 2024, and is expected to remain valid until Q4 2027.
