Your company has two FastConnect circuits connecting your on-premises network to OCI.

Objective: Load balance OCI-to-on-premises traffic over two FastConnect circuits.

Option A: Different MEDs prioritize one path, not balance—incorrect.

Option B: Same prefixes and attributes enable Equal-Cost Multi-Path (ECMP) routing, balancing traffic—correct.

Option C: AS Path Prepending prefers one path—incorrect.

Option D: Local preference prioritizes one path—incorrect.

Conclusion: Option B ensures load balancing.

Oracle states:

"For load balancing over multiple FastConnect circuits, advertise identical prefixes with the same BGP attributes to enable ECMP."This supports Option B. Reference:FastConnect BGP - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/fastconnect.htm#BGP).
