After architects create network designs, Cisco Engineers implement changes to their arrangement taking into account issues, such as traffic logjams, upgrading of essential infrastructure, troubleshooting issues inconveniencing customers, undertaking precautionary maintenance, etc. Engineers must be able to understand how complex networks work and identify problems, besides advising on how to improve them. They should be well versed with security, virtualization, containers, storage engineering, and wide area networking (WAN). They must create a dependable optimally functioning network, which integrates the Internet, Intranet, LAN, and WAN sections, involving network designing and analysis.
Engineers should have knowledge of computers, routers, firewall, and switches, among others, for performing maintenance of the network and upgrading the system, including patches, service packs, security configurations, and hot fixes. They must be capable of acquiring more knowledge by continuing education or through other avenues.
Engineers develop device drivers, design network applications, and use script and web languages to write new programs. They test hardware and develop new hardware and design. They design and test routers, flash drives, modems, and power converters. https://www.fieldengineer.com/skills/cisco-engineer
