Citrix NetScaler 11 Essentials and Networking

Our classes are always live and instructor led from our Exton, PA or EPIC Partner locations. Springhouse AnywhereLive options require Internet Access. Select classes are Guaranteed to Run (GTR). View our complete schedule policies.






​The objective of the Citrix NetScaler 10.5 Essentials and Networking course is to provide the foundational concepts and advanced skills necessary to implement, configure, secure, monitor, optimize, and troubleshoot a Citrix NetScaler system from within a networking framework. This course is designed specifically for learners who have limited or no previous NetScaler experience. In order to successfully complete this course, learners will have access to hands-on exercises within a virtual lab environment. An optional module on NetScaler SDX appliances is included with reinforcement simulation exercises.

This course is based on the Citrix NetScaler 10.0 product, but the skills and fundamental concepts learned are common to earlier product versions.

Intended Audience

This course is recommended for learners* who are:

  • New to the NetScaler platform
  • Currently networking professionals

*For administrators interested in integrating NetScaler Gateway, please refer to CNS-207 Implementing Citrix   NetScaler 10 for App and Desktop Solutions. 

At Completion

​Upon successful completion of this course, learners are able to:

  • Identify the capabilities and functionality of the NetScaler
  • Explain basic NetScaler network architecture
  • Obtain, install, and manage NetScaler licenses
  • Explain how SSL is used to secure the NetScaler
  • Implement NetScaler TriScale Technology, including Clustering
  • Configure advanced load balancing and GSLB on the NetScaler system
  • 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


​Before taking this course, it is recommended that learners have professional networking knowledge. They need not have a NetScaler background as such. For customers already using the NetScaler for load balancing, the course will provide in depth training on load balancing and other related traffic management/optimization features allowing users to go beyond basic load balancing.

Exams & Certifications

​CNS-205 prepares you for 1Y0-350 exam, Citrix NetScaler 10 Essentials and Networking, a requirement for Citrix Certified Professional - Networking (CCP-N) certification. Designed for Network Engineers, this certification validates the knowledge and skills needed to implement, manage and optimize Citrix NetScaler 10 for networking performance and optimization Students should note CCA-N is not a prerequisite for the CCP-N
