Implementing Cisco Application Centric Infrastructure (DCACI) — Question 86

A company must connect three Cisco ACI data centers by using Cisco ACI Multi-Site. An engineer must configure the Inter-Site Network (ISN) between the existing sites. Which two configuration steps must be taken to implement the ISN? (Choose two.)

Answer options

• A. Configure OSPF on subinterfaces on routers that are directly connected with spine nodes.
• B. Configure ISN site extension on Cisco routers in the network.
• C. Configure OSPF on all ISN routers.
• D. Configure BIDIR-PIM on all ISN routers.
• E. Configure encapsulation VLAN-4 between the routers and spine nodes.

Correct answer: A, E

Explanation

The correct steps to implement the ISN are to configure OSPF on subinterfaces on routers directly connected to the spine nodes (A) and to set the encapsulation to VLAN-4 between the routers and spine nodes (E). Options B, C, and D are incorrect because they either misinterpret the configuration requirements or suggest incomplete setups for establishing a robust ISN.
