[: Cisco APIC Layer 3 Configuration Guide, "Configuring Logical Interface Profiles for L3Out" and "Multi-Homing L3Out.", B. Add a second subnet to the external EPG to the existing L3Out: , Adding a subnet to the external EPG defines additional networks advertised or learned via the L3Out, but it does not address the addition of a new physical link or path. This is irrelevant to the connectivity requirement for the second link., Reference: Cisco ACI External EPG Configuration Guide., C. Add a second OSPF interface profile to the logical interface profile: , While the L3Out uses OSPF (implied by the context), adding a second OSPF interface profile would create a separate routing instance, which is unnecessary and could disrupt consistency. The existing OSPF configuration can be extended via the logical interface profile., Reference: Cisco APIC OSPF Configuration Guide., D. Add a second interface to the external domain to the existing L3Out: , The external domain associates VLAN pools, but it does not define paths or interfaces for L3Out connectivity. This option is incorrect as it confuses domain configuration with interface path management., Reference: Cisco ACI Domain Configuration Guide., Final Answer Justification, A is correct because adding a second path to the logical interface profile of the existing L3Out integrates the new link from BL-1002 to Core-2 into the same routing and policy framework, ensuring equivalent connectivity to the Core-1 to BL-1001 link. This aligns with ACI’s support for multi-homed L3Outs., Primary Cisco References: , Cisco APIC Layer 3 Networking Configuration Guide, "L3Out Multi-Homing.", Cisco ACI Best Practices, "Expanding L3Out Connectivity.", , ]
