When migrating workloads requiring high availability and redundancy for on-premises connectivity to OCI, which approach...

Requirements: HA and redundancy for on-premises-to-OCI connectivity.

Option A: Single FastConnect lacks redundancy—incorrect.

Option B: Single VPN over internet has no redundancy and poor performance—incorrect.

Option C: Dual FastConnect with diverse paths ensures HA and redundancy via separate routes—correct.

Option D: Internet Gateway with public IPs isn’t dedicated or redundant—incorrect.

Conclusion: Option C is the recommended approach.

Oracle advises:

"For high availability, use dual FastConnect connections with diverse paths to eliminate single points of failure in hybrid connectivity."This supports Option C. Reference:FastConnect High Availability - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/fastconnect.htm#ha).
