Which ACI object is used to divide two applications that use the same IP address?
A. bridge domain
B. EPG
C. VRF
D. tenant
Correct Answer: A
Explanation/Reference:
Explanation:
One or more bridge domains are associated with a context. All of the endpoints within the Layer 3 domain must have unique IP addresses because it is possible to forward packets directly between these devices if the policy allows it. A tenant can contain multiple contexts.

C
Tenants can be further divided into contexts, which directly relate to Virtual Routing and Forwarding (VRF) instances, or separate IP spaces. Each tenant can have one or more contexts, depending on the business needs of that tenant. Contexts provide a way to further separate the organizational and forwarding requirements for a given tenant. Because contexts use separate forwarding instances, IP addressing can be duplicated in separate contexts for multitenancy.
