The Cisco CCNP® curriculum includes four modules, which align with the four exams required for CCNP certification. The CCNP curriculum builds on Cisco CCNA® courses with more complex network configurations, diagnosis, and troubleshooting. The curriculum is intended for those interested in continuing their post-CCNA preparation to become network administrators, Level 2 support engineers, Level 2 systems engineers, network technicians, or deployment engineers. Students interested in this course should have completed CCNA 1-4, or the equivalents. CCNA certification is also desirable; however, it is not a prerequisite. The new CCNP courses can be taken in any order. However it is recommended that students take Building Multilayer Switched Networks before taking Optimizing Converged Networks. The four courses include: Building Scalable Internetworks, Implementing Secured Converged Wide-area Networks, Building Multilayer Switched Networks, and Optimizing Converged Networks.
