A pure IP fabric is a network design where all devices operate at Layer 3, meaning that each device in the fabric is a router that makes forwarding decisions based on IP addresses.
Layer 2 Support:
In a pure IP fabric, traditional Layer 2 protocols such as Spanning Tree Protocol (STP) or VLANs are not supported. Instead, the network relies entirely on Layer 3 routing protocols to manage traffic between devices.
Routing Functionality:
Since devices in an IP fabric operate as Layer 3 routers, they handle IP routing and provide network services based on IP addresses, not on MAC addresses or Layer 2 switching.
Conclusion:
Option A:Correct—Devices in an IP fabric function as Layer 3 routers.
Option D:Correct—A pure IP fabric does not support traditional Layer 2 protocols, making it a purely routed environment.
