Refer to the exhibit. A Cisco ACI fabric has these configurations: - VPC exists between Leaf2 and Leaf3. - A switch profile called SW_Prof exists. - A switch selector called SW_Selec exists. - An…

To associate Leaf2 and Leaf3 with the overall access policy structure, the switch selector (SW_Selec), which identifies the specific leaf nodes, must be mapped or associated under the switch profile (SW_Prof). This step integrates the selected switches into the defined profile's policies.

Adding Leaf2 and Leaf3 node IDs under the switch selector SW_Selec is how specific nodes are selected, which is a prerequisite, but the mapping in option A and the explicit VPC group in option E are distinct, necessary actions.

Explicit VPC groups are configured under the access policies section of the ACI fabric hierarchy, specifically under `Access Policies > Interface Policies > Policy Groups > VPC Explicit Protection Groups`, not under fabric policies.

Leaf nodes are selected using a switch selector, which is then associated with a switch profile; node IDs are not typically added directly under a switch profile itself.

The explicit VPC group is a critical configuration that defines the Virtual Port Channel peer relationship between the two leaf switches (Leaf2 and Leaf3) and is always created within the access policies to enable VPC functionality for connected devices like Server1.
