In the context of Cisco ACI (Application Centric Infrastructure), TEP (Tunnel Endpoint) addresses are used for encapsulating and forwarding traffic within the fabric. The next hop addresses mentioned in options A and D are indicative of TEP addresses, which are typically assigned to border leaf switches within the ACI fabric. These border leaf switches are responsible for routing traffic between the ACI fabric and external networks. * Option A is correct because the next hop 10.0.1.14 for the route 172.16.99.0/24 is consistent with the TEP address format used in ACI, suggesting it is the TEP address of a border leaf. * Option D is also correct as the next hop 10.1.168.95 for the route 172.16.100.0/24 follows the TEP address pattern, indicating it is the TEP address of another border leaf in ACI.
