SPACI - ACI for Service Providers Course Details:

In this course, you will examine Cisco Application Centric Infrastructure (ACI) use cases for service provider environments, which include policy-driven configurations, design details, multi-tenant internal and external network integration and migration, routing protocol exploration, security implications, and disaster recovery solutions. You will perform various scenario-driven configurations and testing in lab exercises using hand-on labs. You will learn how to simplify complex routing deployments and reduce the time and cost required to provision customer networking needs while maintaining both ACI and non-ACI networks. Finally, you will learn to support site redundancy including disaster recovery solutions both at the customer site and public cloud provider levels while maintaining the integrity of customer data and hardening of sensitive information.
