CCNE - Cisco Certified Network Expert
CCDA - Cisco Certified Design Associate
CCDP - Cisco Certified Design Professional
CCDE - Cisco Certified Design Expert
CCNA certification is a first-level Cisco Career certification and indicates a foundation in and apprentice knowledge of networking. CCNA certification 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. To become Cisco certified, a passing score on the [640-802] exam must be achieved.
CCNA certifications are valid for three years. To recertify you must pass one of the following exams:
- the current CCNA exam
- the current ICND2 exam
- a current CCNA concentration exam (IINS, IIUC, or IUWNE)
- any professional-level exam (of the 642 category)
- any Cisco Specialist exam (excluding Sales Specialist exams)
- a current CCIE written exam
