N222: NetScaler for Apps and Desktop {CNS-222-1I} Course Outline

 (5 days)

Designed for students with little or no previous NetScaler, NetScaler Gateway or Unified Gateway experience, this course is best suited for individuals who will be deploying or managing NetScaler, NetScaler Gateway, or Unified Gateway environments.

What’s New
The course has been completely redeveloped and improves upon CNS-207: Implementing Citrix NetScaler 11 for App and Desktop Solutions via the following:
Improved course structure and flow to focus on NetScaler essentials for the first 3 days, and NetScaler Gateway and Unified Gateway features for the remaining 2.
A new lab environment, redesigned and built for enhanced performance.
Incorporated course feedback that has been gathered over the last year.
New content introduced throughout the course.

Part 1: NetScaler Essentials (Days 1-3)
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 Gateway and Unified Gateway (Days 4-5)
Learn the skills required to configure and manage NetScaler Gateway and Unified Gateway features, including how to implement Gateway components including NetScaler Gateway and Unified Gateway. At the end of the course students will be able to configure their NetScaler environments to address remote access requirements for Apps and Desktops.

Recommended pre-requisite courses:
CNS-102 NetScaler Overview
Note: Students looking to expand their knowledge around NetScaler Traffic Management functionality are recommended to take CNS-220 (Citrix NetScaler Essentials and Traffic Management) instead of this class.
This course is based on the Citrix NetScaler 11 product, but the skills and fundamental concepts learned are common to earlier product versions.
Key Skills
 Identify the functionality and capabilities of the NetScaler
 Explain basic NetScaler network architecture
 Explain how SSL is used to secure the NetScaler
 Configure Authentication and Authorization
 Define End User Access and Experience
 Integrate NetScaler Gateway with XenApp and XenDesktop
 Integrate Unified Gateway with additional resources
 Employ recommended tools and techniques to troubleshoot common NetScaler Gateway network and connectivity issues

Students interested in learning how to implement and manage the advanced NetScaler features using leading practices. Specifically:
Implementers / Engineers

Course Length
5 days

Course Materials
As part of this course, students will receive the following materials:
Access to a lab environment for the duration of the course
Lab exercise guide
Access to final course deliverables once the course is available in general availability including copies of all official materials presented by the instructor with additional notes and references as well as videos with experts throughout Citrix around course topics and lab exercises.
