Correct Answer: ATo configure Rome WAN Edge to use the MPLS cloud as the preferred link to reach Paris WAN Edge, and the biz-internet as a backup, the Track List Object (TLOC) associated with MPLS and biz-internet must be defined for the Rome WAN Edge IP address (10.1.1.102). Hence, the correct policy configuration should include the IP address of the Rome WAN Edge along with the appropriate preferences for MPLS and biz-internet. Option A correctly specifies the TLOC list for IP address 10.1.1.102 with a color of 'mpls' having a higher preference (500) than 'biz-internet' (400), which aligns with the requirement of preferring MPLS and using biz-internet as a backup.
