This certification is to be a Cisco Certified Technician (CCT) to perform on site installation on maintenance of the products that they offer. There are three tracks that you can choose from when going for this certification: Routing & Switching, Data Center, and TelePresence, and there is a separate exam (priced at $125) for each track which you must pass to gain the certification. Apparently, you must have the Routing & Switching certification before you can apply for either of the others, which means that if you want either of the other two, you will have to throw down at least $250. This certification lasts for a total of 3 years and to get re-certified, you must pass one exam from the list given here. On Indeed.com, there are a considerable number of jobs available for those with Cisco Certifications, so if you are in this field, it might be a good bet.
