Why each option
Cisco FabricPath and vPC both provide data center resiliency by enabling redundant, active-active forwarding paths without the limitations of traditional STP.
FabricPath eliminates Spanning Tree Protocol blocking by using a routed-like IS-IS control plane, enabling all links to actively forward traffic and providing loop-free resiliency across the fabric.
VTP (VLAN Trunking Protocol) propagates VLAN configuration across switches but provides no resiliency or redundancy for data forwarding.
Encryption protects data confidentiality in transit but does not provide any forwarding path redundancy or resiliency.
vPC (virtual Port Channel) allows a downstream device to form port channels to two separate upstream switches simultaneously, eliminating single points of failure and enabling active-active uplink forwarding.
VRF (Virtual Routing and Forwarding) provides network segmentation by creating multiple isolated routing tables but does not provide resiliency against link or device failure.
