CNS 220 – Citrix NetScaler Essentials and Traffic Management
5 days  (Instructor Led Online)  |  Networking

Course Details

The CNS 220 – Citrix NetScaler Essentials and Traffic Management course is best suited for individuals who will be deploying or managing NetScaler environments or students with little or no previous NetScaler experience.

The course structure and flow to focus on NetScaler essentials for the first three days, and traffic management for the remaining two days. 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 Traffic Management (Days 4-5)

  • 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.

Citrix course materials are only available to delegates in e-courseware format. Delegates will be provided with instructions on how to access their e-courseware on day one of the events. Those delegates who are attending via either virtual or extended classroom will be required to provide either three monitors (to view courseware, labs and instructor demos simultaneously) or two monitors and a mobile device.

 

Delegates will be required to have an active TCC (Training.Citrix.com) account in order to access course materials and labs. Please set up Your TCC account up in advance of the course using the following link: https://www.citrix.com/welcome/create-account/create-account-form.html

Please note: It is highly recommended that the delegate uses a personal email address (rather than company email) to set up their TCC account. If you do not wish to reference your company name when setting up your TCC account we recommend you use ‘EDUCALC’ as reference.

Should you encounter any issues in setting up your TCC account please ensure that you raise this directly with Citrix in advance of your event by visiting http://training.citrix.com then on the home page click, Help, then select Classroom Support and submit a Critical or High priority request notifying Citrix of the course start date.
