I'm happy to share that my LinkedIn Learning course, Network Quality of Service (QoS) Foundations: Managing Network Traffic, has been selected for inclusion in the **National Association of State Boards of Accountancy Continuing Professional Education (CPE) program starting next quarter. It's an honor to have the course recognized as part of a professional continuing education program, helping learners earn CPE credit while strengthening their networking and QoS knowledge. Thank you to the LinkedIn Learning team and to everyone who has supported my training content. https://www.linkedin.com/learning/network-quality-of-service-qos-foundations-managing-network-traffic/the-need-for-qos?autoSkip=true&resume=false
