Description:

The course NT101 Network Administration Advanced builds on the fundamentals of the training NT100 Network Administration Basics and provides the participant with deep, vendor-independent insight into protocols and design patterns as well as solutions to complex problem scenarios in the network domain.
The focus is on practical exercises and providing an overview, so that after completing the course, participants will be able to understand and classify new (and old) technologies more easily. This is complemented by numerous exercises in workshop format using dedicated physical and virtual hardware from various vendors and technologies (such as CISCO, Juniper, Arista, Nokia, native OpenSource). This workshop format also allows us to respond more deeply to the individual needs of participants.
