To configure Rome WAN Edge to prefer the MPLS cloud for reaching Paris WAN Edge, and use biz-internet as a backup, the policy must be set correctly to define the preference for each transport link.

Understanding TLOCs (Transport Locator): TLOCs represent the transport network paths (MPLS, Internet, etc.) available for SD-WAN. The preference values assigned to TLOCs determine their priority. A lower preference value indicates a higher priority.

Policy Configuration Analysis:

Option A: This option correctly configures the TLOC list for the system IPs representing the MPLS and biz-internet links with the appropriate preferences (500 for MPLS and 400 for biz-internet).

Other options either repeat the TLOC configuration incorrectly or reference wrong system IPs.
