Selected Answer: D
D. When a bridge domain is extended out of a Cisco ACI fabric, policies are used to identify the connectivity between Endpoint Groups (EPGs) and the external connection by using L2Out and L3Out. L2Out and L3Out stand for Layer 2 and Layer 3 outside connectivity, respectively. L2Out is used to bridge traffic outside the ACI fabric, while L3Out is used to route traffic outside the fabric. These connectivity options use contracts, which define the communication rules between the internal and external EPGs. Internal EPGs are the EPGs within the ACI fabric, and external EPGs are the EPGs outside the ACI fabric.

Selected Answer: C
It's asking between which components you "enable" connectivity from EPGs to external in this case. So it's between an EPG and an external EPG.

It should not be a surprise by now that communication with devices and networks outside the fabric is enabled through the use of groups and contracts. In the following subsection, we look at the flexibility of using these groups to provide external connectivity to devices inside the fabric.

Selected Answer: C
It's C. Policies (contracts) are applied between EPGs, not directly between L2OUT and/or L3OUT. In our case, we don't have an L3out. The bridge domain extended outside the ACI fabric is the L2OUT, which is the "external" connection. EPGs that belong to this L2OUT are called external EPGs.

Selected Answer: C
Definitely C, even L2Out and L3out are used for external communication with internal EPGs. The contracts used for communication MUST BE assigned in the ext-epgs, as shown in the JCGO link.

I think they are testing terminology. The key word is "policies".
| Category | Examples | What they do |
| ------------------------ | ---------------------------------------- | ----------------------------- |
| **Connectivity objects** | EPGs, L2Out, L3Out, Bridge Domains, VRFs | Define topology and attachment |
| **Traffic policies** | Contracts, Filters, Subjects | Define what communication is allowed |
| **Attachment policies** | AAEP, Interface Policy Groups | Define where endpoints connect |
| **Behavioral policies** | QoS, PBR, Service Graphs | Change traffic handling |
