Which two external entities are referenced by an AEP? (Choose two.)
The correct answer is A. Layer 3 domain C. VMM domain. An Attachable Access Entity Profile (AEP) in Cisco ACI links physical infrastructure elements like ports and VMM domains to policy groups and Layer 3 external domains.

Why each option
An Attachable Access Entity Profile (AEP) in Cisco ACI links physical infrastructure elements like ports and VMM domains to policy groups and Layer 3 external domains.
A Layer 3 domain is an external entity that an AEP can reference, as AEPs associate physical interfaces and related policies to external routed networks defined within these domains.
While a hypervisor hosts virtual machines that connect to ACI via a VMM domain, the hypervisor itself is not directly referenced by an AEP; the VMM domain is the higher-level abstraction that ACI interacts with.
A VMM domain, representing a virtual machine manager like VMware vCenter or Microsoft Hyper-V, is directly referenced by an AEP to allow the ACI fabric to push network configurations to the virtual infrastructure.
A Fibre Channel switch is part of a storage network and is not directly referenced by an AEP, which is primarily concerned with Ethernet-based network connectivity policies.
VMware vCenter server is an example of a Virtual Machine Manager (VMM); the AEP references the VMM domain as an abstraction, not the specific vCenter server instance directly.
