The correct answer is D. Implement the two data centers into an ACI Multi-Site solution.. ACI Multi-Site gives you two independent fabrics (so the secondary DC’s tenant workloads stay isolated) while enforcing a single, centrally managed policy model. You get Layer 3 fabric‑wide connectivity by default, and you can selectively extend only the needed VLANs/Bridge Domai
Question
An international corporation migrates its primary and secondary data centers to Cisco ACI. The new architecture must include a disaster recovery solution for critical applications in the primary data center with these requirements:
- The secondary data center hosts dedicated workloads, which must
remain isolated from the primary data center.
- Critical applications must have both Layer 3 and Layer 2 connectivity
between data centers.
- The ACI policy must be consistent across the data centers.
- Flooding between the data centers must be restricted to specific
VLANs. Which solution must be used to accomplish these goals?
Options
- ADeploy two independent ACI fabrics and use LISP for L3 mobility.
- BDeploy a pair of ACI Remote Leafs in the secondary data center.
- CImplement Cisco ACI using a Multi-Pod architecture.
- DImplement the two data centers into an ACI Multi-Site solution.

Explanation
ACI Multi-Site gives you two independent fabrics (so the secondary DC’s tenant workloads stay isolated) while enforcing a single, centrally managed policy model. You get Layer 3 fabric‑wide connectivity by default, and you can selectively extend only the needed VLANs/Bridge Domains for L2 connectivity (limiting flooding) via the Multi-Site overlay. This meets the isolation, policy consistency, and controlled L2/L3 extension requirements.
