Which keyword is used to choose a specific type of tunnel when SLA class is matched by the data traffic?

'sia-preferred-color' is not a standard or recognized keyword for tunnel selection in Cisco SD-WAN data policies.

The 'preferred-color' keyword allows an administrator to define a specific color (e.g., MPLS, LTE, biz-internet) that should be prioritized for traffic flow when a data policy's SLA class is successfully met. This keyword helps in traffic engineering by steering traffic over desired tunnel types.

'default' is a general keyword used for default actions or values in various configurations, but it does not specify a particular tunnel type for SLA matching.

'strict' is a keyword often used in path preference or SLA class definitions to enforce strict adherence to SLA parameters, but it doesn't directly choose a specific tunnel color.
