LINX Accredited Internet Technician II  |    A 5 day   hands on   training course

LINX II training course description

An intensive hands on IP routing course leading to LINX Accredited Internet Technician stage 2 focusing on routing in an IP environment. The course concentrates on OSPF and IS-IS but also covers BGP and MPLS. Hands on sessions are used to reinforce the theory rather than teach specific manufacturer equipment.
A multiple choice exam, leading to the LAIT II certification, is available after the course. The exam consists of 60 questions and lasts 2.0 hours.

What will you learn
  • Calculate subnet numbers in seconds.
  • Configure and troubleshoot static routes
  • Explain how OSPF works.
  • Build resilient networks with VRRP and OSPF.
  • Implement and troubleshoot OSPF, IS-IS, simple BGP and simple MPLS.
  • Evaluate and choose appropriate routing protocols for particular scenarios.
LINX II training course details
  • Who will benefit:
  • Network engineers.

  • Prerequisites:
  • LAIT I attendance and 55%+ exam score OR LAIT I exam only and pass (70%+) OR CCNA and take LAIT I exam on this course.
