What is the requirement to establish connectivity in the Cisco ACI fabric between two EPGs in separate tenants?
The correct answer is D. scope global contract. To enable communication between End Point Groups (EPGs) residing in different tenants within a Cisco ACI fabric, a contract with a global scope is required. This scope allows the contract to be consumed across tenant boundaries.

Why each option
To enable communication between End Point Groups (EPGs) residing in different tenants within a Cisco ACI fabric, a contract with a global scope is required. This scope allows the contract to be consumed across tenant boundaries.
A contract with a tenant scope is restricted to EPGs within the same tenant and cannot be used for communication between EPGs in separate tenants.
"Private contract" is not a standard contract scope or type in Cisco ACI.
While "intertenant" describes the goal, "intertenant contract" is not a recognized contract scope keyword in Cisco ACI; the correct scope for this functionality is global.
A global scope contract is necessary to permit communication between EPGs that belong to different tenants. The global scope ensures that the contract policy is visible and consumable across the entire ACI fabric, including across tenant boundaries, thereby enabling inter-tenant EPG communication.
