Cisco Certified Technician (CCT)
Each certification focuses on the on-site maintenance and support of Cisco equipment in each specific area.
You might be wondering what is the difference between the CCT and the CCENT? Cisco explains that and several more questions in their FAQ, but for those not interested in reading through all of that, here's the basics...
The CCT is focused on on-site maintenance of equipment rather than the configuration and installation of equipment. The CCENT is more focused on installation and configuration of a branch office or small business network. The CCENT is also one half of the required material to become a CCNA, which is geared toward entry level Network Engineers who configure anything from WAN protocols and OSPF to spanning-tree and port channels. In other words, the CCT is the first stepping stone toward a broader career in networking.
So, if you are looking for a way to switch careers from system administration or dentistry to networking and are interested in getting your foot in the door somewhere, the CCT may help get you into an entry level position quicker than the time it takes to study for and achieve a CCNA.
