Define what IIoT is and identify IIoT architectures.  

• Identify IIoT market verticals, and their motivations and requirements.
• Explore Cisco IIoT networking devices, how they are different from other devices, and use common administrative tools for managing them.
• Explore industrial communications protocols for control and automation, and how they have been adapted to run on top of a TCP/IP network infrastructure.
• Describe wireless protocols used in IIoT environments, including architectures and devices used.
• Understand the TCP/IP protocol stack and how it is used with other protocols in IIoT environments.
• Discuss network protocols for clock synchronization between network devices, and describe available tools for IIoT network administration.
• Discuss wireless technologies used in a core LAN, and their relevance to IIoT implementations.
• Explore field WAN technologies and how they are used in IIoT environments.
• Explore legacy protocols and explain the methods available to transport non-routable protocols over modern networks.
• Explain fundamental concepts of Quality of Service (QoS) related to IIoT network environments.
• Discuss Multiprotocol Label Switching (MPLS) operation, components, terminology, and features, and explore its use in IIoT environments.
• Explore Layer 2 and Layer 3 VPN technologies and describe the way they can be used on IIoT deployments.
• Describe Dense Wave Division Multiplexing (DWDM) technology and its use in IIoT environments.
• Explore Layer 1 and Layer 2 high availability technologies and redundancy mechanisms.
• Describe Layer 3 high availability and the need for Layer 3 redundancy in IIoT deployments
