Instead of taking both the ICND1 and ICND2 classes and exams, learners have the option of taking one accelerated class and exam instead. The CCNA course covers all the material necessary to earn your CCNA certification, the prerequisite for many higher-level Cisco certifications. CCNA training teaches you the skills you need to install, configure, and troubleshoot Cisco routing and switching products, as well as introductory security and wireless technologies used by small and medium sized businesses.
