Cisco certification ensures high standards of technical expertise. You will develop a complete understanding of Wide Area Networking and how different network topologies work together to form a network. This is beneficial to every networking job and is the reason Cisco certification is in such high demand, even at companies with few Cisco devices. Achieving Cisco certification—at any level—means joining the ranks of skilled network professionals who have earned recognition and respect in the industry. The CCNA certification is the first in the new line of Cisco certifications and is a precursor to all current Cisco certifications.
