Citrix NetScaler Traffic Management Essentials (CNS-220)

Course code: CNS-220

Exam Code: CNS-220

Duration: 40 Hours

In this course, you will learn the skills that are required for implementing NetScaler components including secure load balancing, high availability, and NetScaler management. You will learn how to configure your NetScaler environments to address traffic delivery and management requirements including load balancing, availability, and NetScaler operation management.

You will also learn how to configure and manage NetScaler Traffic Management features, including content switching, traffic optimization, and global server load balancing. At the end of the course, you will be able to configure your NetScaler environments to address efficient traffic switching and resilience requirements including content switching, traffic optimization, and disaster recovery.

This course is based on the Citrix NetScaler product but the skills and fundamental concepts are common to earlier product versions. A voucher for the Citrix Certified Professional – Networking (CCP-N) exam will be issued in this course.
