What specifies the connectivity policy between vSphere and the ACI fabric?

The correct answer is the VMM Domain because it explicitly defines the connectivity and policy settings that integrate VMware vSphere environments with the ACI (Application Centric Infrastructure) fabric. The VMM (Virtual Machine Manager) Domain serves as a critical component in orchestrating these environments, as it allows for the management of network resources and ensures that the virtualized workloads are in alignment with ACI’s centralized policy model.

In this context, the VMM Domain essentially acts as a bridge, translating the virtual network requirements from vSphere to the policy-driven fabric of ACI. This integration allows for dynamic adjustments based on policy changes, facilitating features like automatic provisioning and consistent policy enforcement across the data center.

Other options, while related to networking and virtual environments, do not specifically address the connectivity policy between vSphere and the ACI fabric in the same comprehensive manner. For instance, a Domain typically refers to a broader organizational unit in networking, VLAN pertains predominantly to Layer 2 network segmentation, and Virtual Domain can be an ambiguous term that does not capture the specific role of VMM Domain in this integration scenario. All these elements play roles in network management, but the VMM Domain uniquely specifies how these two systems communicate and adhere to policies set forth by the A
