A bridge domain is being extended out of a Cisco ACI fabric. Between which of these components are policies used to identify the connectivity between Endpoint Groups and the external connection?
When a bridge domain is being extended out of a Cisco ACI fabric, policies are used to identify the connectivity between Endpoint Groups (EPGs) and the external connection through L2Out and L3Out. L2Out is used for extending Layer 2 connectivity, while L3Out is used for extending Layer 3 connectivity. These mechanisms involve the use of contracts to define the communication rules between internal EPGs within the ACI fabric and external EPGs outside the fabric, thereby ensuring the appropriate policy enforcement for outgoing and incoming traffic.
D. When extending a bridge domain out of a Cisco ACI fabric, policies are used to identify the connectivity between Endpoint Groups (EPGs) and the external connection using L2Out and L3Out. L2Out and L3Out represent Layer 2 and Layer 3 outside connectivity, respectively. L2Out is used for bridging traffic outside the ACI fabric, while L3Out is used for routing 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.
Its asking between which components you "enable" connectivity from EPGs to external in this case. So its between an EPG and an external EPG.
C is valid answer. https://learnduty.com/cisco-aci/cisco-aci-l2out-configuration-example-explained/
D is correct
C. internal EPGs and external EPGs
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 showed in JCGO link

between an EPG and an external EPG
C. must be the right answer , Question asking for connectivity between endpoint done by EPGs only
....... 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.
D is correct
