CCNA is Cisco's entry-level certification that validates skills to install, configure, operate, and troubleshoot medium-sized routed and switched networks. Candidates must pass either exam 640-802 or exams 640-822 and 640-816 to earn CCNA certification. These exams test knowledge of networking fundamentals, security, routing, switching, and WAN technologies through multiple choice, drag and drop, testlets, and simulation questions.

passing scores on both theICND1 #640-822 and ICND2 #640-816 exams. Passing the ICND1 grants one
the Cisco Certified Entry Networking Technician (CCENT) certification. Passing scores are set by using
statistical analysis and are subject to change. At the completion of the exam, candidates receive a score
report along with a score breakout by exam section and the passing score for the given exam. Cisco does
not publish exam passing scores because exam questions and passing scores are subject to change
without notice.
