A network architect designs a high-availability architecture for the Cisco UCS Fabric Interconnects that are installed in a data center. The architecture must support clustering and redundancy.
Which architecture meets these requirements?
A.
dual connections from port L1 to L1 and one connection from port L1 to L1 with twinax cables
B.
dual connections from port L1 to L2 and one connection from port L2 to L1 with twinax cables
C.
dual connections from port L1 to L2 and one connection from port L2 to L1 with Ethernet cables
D.
dual connections from port L1 to L1 and one connection from port L2 to L2 with Ethernet cables
It is D.
To use the cluster configuration, the two fabric interconnects must be directly connected together using Ethernet cables between the L1 (L1-to-L1) and L2 (L2-to-L2) high availability ports, with no other fabric interconnects in between.

Did a bit more reading, I agree with C now based on this article:
https://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/sw/gui/config/guide/141/UCSM_GUI_Configuration_Guide_1_4_1_chapter4.html#:~:text=To%20use%20the%20cluster%20configuration,other%20fabric%20interconnects%20in%20between.
Answer should be C: dual connections between L1 and L2 ports on each fabric interconnect with standard Ethernet cables provides a redundant high-availability architecture in a data center.
