Instructor Notes
This module provides students with an overview of Network Load Balancing concepts. The module begins by comparing various load balancing technologies and identifies the applications and services that benefit from a clusteringsolution. The students are then introduced to the functionality and configuration of the Network Load Balancing driver.

After completing this module, students will be able to:
- Describe the concepts of the Network Load Balancing solution.
- Describe the application and services configuration for Network Load Balancing hosts.
- Describe the functionality of the Network Load Balancing driver.
- Identify the components for the Network Load Balancing driver architecture.
