This course introduces you to the Cisco technologies that are deployed in the Data Center. The introductory level of content is focused on basic concepts like Ethernet, the OSI Layer Model, and TCP/IP. It then takes you through basic configuration tasks, including VLANs, network addressing, and subnet masks. Together with Introducing Cisco Data Center Technologies (DCICT), this course prepares you for the CCNA Data Center certification.

Upon completing this course, you will be able to meet these overall objectives:

Describe how a network works
Configure, verify, and troubleshoot a switch with VLANs and interswitch communications
Implement an IP addressing scheme and IP services to meet network requirements
Configure, verify, and troubleshoot routing operations on Cisco Nexus switches
