Network Technicians support the highest level of technical/network staff in an organization and will occasionally be involved with direct user support. The Network Technician will assist with the overall health of the network, server deployments, security, ensuring network connectivity throughout a company's LAN/WAN infrastructure, and all other technical considerations at the network level of an organization's technical hierarchy. Network Technicians are considered Tier 3 support personnel that only work on break/fix issues that cannot be resolved at the Tier1 (helpdesk) or Tier 2 (desktop/network technician) levels. The actual role of the Network Technician will vary from company to company, but will commonly include activities and tasks such as network address assignment, assignment of routing protocols and routing table configuration as well as configuration of authentication and authorization - directory services. It often includes maintenance of network facilities in individual machines, such as drivers and settings of personal computers as well as printers and such. It sometimes also includes maintenance of certain network servers: file servers, VPN gateways, intrusion detection systems, etc. Network specialists and analysts concentrate on the network design and security, particularly troubleshooting and/or debugging network-related problems. Their work can also include the maintenance of the network's authorization infrastructure, as well as network backup systems. The technician is responsible for supporting the Network Administrator in setting up security for the network and for assigning IP addresses to the devices connected to the networks. Assigning IP addresses gives the subnet administrator some control over the professional who connects to the subnet. It also helps to ensure that the administrator knows each system that is connected and who personally is responsible for the system. Next Page: Certification Previous Page: Program Overview
