Selected Answer: AC
VPNv4 Prefix (A): This is a combination of the customer’s IPv4 prefix and an 8-byte Route Distinguisher (RD), which makes the prefix globally unique across different VPNs. Extended-Community (C): This includes attributes such as Route Target (RT) and other community values that control how VPNv4 routes are imported and exported across different VRFs (Virtual Routing and Forwarding instances) on the MPLS routers.

VPNV4 prefix is not an attribute, SPN label is an attribute.
