Implementing Cisco ACI Advanced (DCACIA) — Question 89

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

Correct answer: C, D

Explanation

The correct answer is C and D because configuring the ISN site extension on Cisco routers is essential for establishing the Inter-Site Network, and enabling OSPF on all ISN routers is necessary for proper routing between sites. Options A, B, and E are not relevant to the fundamental steps required to implement the ISN in this scenario.
