Course: CompTIA Network+

The key objective of the course is to provide enough information for a delegate to become a competent network support engineer, capable of taking and passing the Network+ Certification test.

Delegates should have taken and passed both A+ Certification examinations, plus have six months to one year of post A+ Certification support experience. Delegates should also have extensive experience of supporting end-users and PC-based systems.

Delegates will learn how to:

• Install and configure a network client
• Use test equipment to troubleshoot network connectivity
• Recognise and understand the main types of network technologies, protocols and components
• Understand and configure the TCP/IP protocol

Leads to examination:
N10-003 - CompTIA Network+

Leads to certification:
CompTIA A+ and Network+
