Why each option

Virtual Routing and Forwarding (VRF) is the technology used on Cisco NX-OS platforms to create multiple independent routing tables for different tenants.

ACisco FabricPath

Cisco FabricPath is a Layer 2 multipathing technology for data center fabrics, designed for loop-free forwarding and scalability, not for creating separate Layer 3 routing tables.

BVLANs

VLANs segment Layer 2 broadcast domains, but they do not inherently create separate Layer 3 routing tables; routing between VLANs typically occurs within a single routing instance unless VRFs are also used.

CvPC

vPC (Virtual Port Channel) is a Layer 2 multipathing technology that provides link redundancy and increased bandwidth across two Cisco Nexus switches, but it does not create separate routing tables.

DVRFCorrect

Virtual Routing and Forwarding (VRF) enables the creation of multiple independent routing tables within a single router or Layer 3 switch on Cisco NX-OS. This allows different tenants or customers to have their own isolated routing domains, even when sharing the same physical hardware, ensuring routing separation and security.
