The Cisco is partnering with educational institutions around the world. This partnership is known as the Cisco Networking Academy (CNA) program. FCI @ Zagazig University is an accredited Cisco Networking Academy providing training to students who wish to become a network professional. FCI & Cisco Networking Academy What is CCNA Certification Cisco Certified Network Associate (CCNA®) validates the ability to install, configure, operate, and troubleshoot medium-size routed and switched networks, including implementation and verification of connections to remote sites in a WAN.
