The Complete Network Infrastructure, Troubleshooting and Diagnostics Course
(NETINF, Live Instructor-Led Training, 4 days)


This SETC Certified course provides participants with a comprehensive introduction to networking in a multi-platform environment. Beginning with the design and architecture of the physical network, the course proceeds to a discussion of logical network design for wither an IPv4 or IPv6 based network. This is followed by an overview of critical network services such as DHCP, DNS, and NAT amongst others.
