Cisco has greatly influenced the IT networking field, urging professionals to acquire a Cisco certification, in order to stay competitive in the industry. Organizations are also demanding the certification, in order to ensure that an IT professional has the relevant expertise in a particular field. It provides the competitive edge in an ever-growing marketplace.

Networking provides an excellent platform for career advancement, while learning other business aspects and ways to enhance human interaction. The CCNA (Cisco Certified Network Associate) certification is a Cisco certification that is becoming a benchmark for many IT companies. A person who has a career experience with Cisco systems can undergo an online training program to prepare for the exam. However, a classroom instruction is important for a person who has not directly worked with Cisco systems. With more and more networking programs launched by Cisco, IT experts need the relevant education to troubleshoot and set up systems. The CCENT (Cisco Certified Entry Networking Technician) is the entry level certification. The subsequent levels in the order of hierarchy are ‘associate’, ‘professional’ and the highest level called ‘expert.’ CCIE (Cisco Certified Internetwork) pertains to the ‘expert’ level. 

As far as networking is considered, Cisco is the industry leader, which implies that a Cisco certification is vital for IT professionals and network designers, in order to gain the appropriate skills. Higher-end certifications ensure assured placements and higher pays for IT professionals.
