# CCNA Prep CML Resources
The CCNA Prep Program is a study resource put together by the Learning and Certifications team within Cisco to help engineers working towards earning their CCNA certification.  Each session dives into a topic from the CCNA blueprint, exploring it through a hands on/labs driven approach. These hands on labs are run on Cisco Modeling Labs and include full lab guides that can be used after the session for anyone to practice and hone their skills as they prepare for their CCNA Exam.  We are sharing the CML topology files with the CML Community for fun, learning and inspiration.

**Hank Preston:** I'm a Principal Engineer at Cisco Systems, and my journey in network engineering began with the CCNA. Over the years, I've earned multiple certifications, including CCNP, CCIE, and DevNet Expert. My passion for networking and teaching has led me to help engineers worldwide through Cisco's learning and certification programs.

**Patrick Gargano:** As a Lead Content Advocate and Instructor at Cisco Learning & Certifications, I am responsible for developing and delivering official Cisco course content. I started my CCNA journey in 2000 when I became a  Cisco Networking Academy instructor. Since then, I've authored Cisco Press books and achieved multiple Cisco certifications. The CCNA was a pivotal point in my career, and I'm excited to share my experiences and insights with you.
