CNS-220 Citrix NetScaler Essentials & Traffic Management

Reference : © Citrix CSN-220

Duration : 5 days

Designed for students with little or no previous NetScaler experience, this course is best suited for individuals who will be deploying or managing NetScaler environments.
What’s New?
This course has been completely redeveloped and improves upon its predecessor CNS-205: Citrix NetScaler Essentials and Networking in the following ways:
  • Improved course structure and flow to focus on NetScaler Essentials for the first three days, and Traffic Management for the remaining two days.
  • New lab environment redesigned and built for enhanced performance.
  • Incorporated enhancements based on feedback gathered over the last year.
  • New content introduced throughout the course.
Part 1: NetScaler Essentials - Days 1-3 (SubCode CNS-218)
Learn the skills required to implement NetScaler components including secure Load Balancing, High Availability, and NetScaler Management. At the end of the course, students will be able to configure their NetScaler environments to address traffic delivery and management requirements including Load Balancing, Availability, and NetScaler Operation Management.
Part 2: NetScaler Traffic Management - Days 4-5 (SubCode CNS-219)
Learn the skills required to configure and manage NetScaler Traffic Management features, including Content Switching, Traffic Optimization, and Global Server Load Balancing. At the end of the course, students will be able to configure their 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 11 product, but the skills and fundamental concepts learned are common to earlier product versions.
LanguagesThese scheduled public sessions are offered in English or in French (FR). The educational material is in English.

Audience

This course is designed for Network Administrators/Engineers, Citrix Administrators, Operations Engineers, Systems Administrators/Engineers and Cloud Administrators/Engineers who are new to the NetScaler platform.
Prerequisites
Recommended pre-requisite course : CNS-102 NetScaler Overview
Note: Students looking to expand their knowledge around NetScaler Gateway functionality should take CNS-207 (Implementing Citrix NetScaler for Apps and Desktop Solutions) instead of this class.

Objectives

Upon successful completion of this course, learners will be able to:
  • Identify the functionality and capabilities of the NetScaler
  • Explain basic NetScaler network architecture
  • Obtain, install, and manage NetScaler licenses
  • Explain how SSL is used to secure the NetScaler
  • Optimize the NetScaler system for traffic handling and management
  • Customize the NetScaler system for traffic flow and content-specific requirements
  • Demonstrate monitoring and reporting through native NetScaler logging tools
  • Employ recommended tools and techniques to troubleshoot common NetScaler network and connectivity issues
  • Implement NetScaler TriScale technology, including clustering
  • Configure advanced load balancing and GSLB on the NetScaler system
  • Identify the functionality and characteristics of the NetScaler SDX platform

Teaching method

This course is offered in instructor-­led (ILT) format with demonstrations and application of concepts through hands-­on exercises in a live lab environment.
