Beskrivning
CompTIA Network+ is the first certification IT professionals specializing in network administration and support should earn.
Network+ helps develop a career in IT infrastructure covering troubleshooting, configuring, and managing networks.
Prerequisites
Students should meet the following criteria prior to taking the course:
- Taken and passed both CompTIA A+ Certification exams or have 9-12 months knowledge and experience of IT administration.
- Be able to configure and support PC, laptop, mobile (smartphone / tablet), and print devices.
- Know basic network terminology and functions (such as Ethernet, TCP/IP, switches, routers).
- Configure and manage users, groups, and shared resources in a simple SOHO network.
- Understand the use of basic access control measures, such as authentication, security policy, encryption, and firewalls.
