At A Glance: Cisco Certified Internetwork Expert (CCIE)
 
Cisco is arguably the most recognizable and respected name in Internet networking technology. Since two Stanford University computer scientists founded Cisco in 1984, the company has maintained its position as a pioneer in Internet protocol-based (IP) network solutions. Cisco Certified Internetwork Expert (CCIE) specialists are some of the most well-respected professionals in the networking industry. Less than 3% of Cisco employees, and less than 1% of networking professionals throughout the world reach this esteemed level of certification. CCIE certification is described by Cisco as its “premium networking certification,” and it is widely regarded as the most prestigious industry certification. In order to obtain such certification, networking engineers must pass a rigorous set of exams, including a day-long lab exam and written exam, in order to prove their merit as the highest-quality Internet networking professionals. These experts typically specialize in areas such as routing, switching, security, and voice systems and technologies. CCIE certificate-holders are highly sought after for their expertise and knowledge in areas such as designing, implementing, troubleshooting, and maintaining complex enterprise networking infrastructures.


On Upwork, you’ll find numerous Cisco Certified Internetwork Experts available for hire to assist you with your networking needs.
