Options

AVPN
Bpreference
CSite ID
Dorigin

Explanation

VPN and preference are vRoute attributes that can be matched or set in vSmart control policies, and the preference attribute can also be modified by data policies for dynamic traffic steering.

Common mistakes.

C. Site ID is a vRoute attribute used for identifying the originating site of a route, and while it can be matched in control policies, it is generally not 'modified by data policies' to influence traffic steering in the same way preference is.
D. Origin is a vRoute attribute indicating how a route was learned (e.g., OSPF, BGP, connected), and while it can be matched in control policies, it is typically not modified by data policies as it reflects the source protocol.
