Refer to the exhibit. You must extend Layer 2 services out of the Cisco ACI fabric configuring contracts for the connected devoices. Which options do you extend?

EPGs are constructs within the ACI fabric that group endpoints with common policies, and while external devices can be part of external EPGs, you do not 'extend an EPG out of the fabric' as a mechanism for L2 services.

Extending Layer 2 services out of the Cisco ACI fabric, for example to remote sites or other data centers, is typically achieved by extending the Layer 2 domain (Bridge Domain) through VXLAN tunnels established with remote VTEPs.

While you extend a bridge domain out of the ACI fabric, 'remote VTEP' is the specific technology that enables this extension over a Layer 3 network, making it a more precise answer.

VMM (Virtual Machine Manager) integration in ACI focuses on connecting hypervisors to the fabric, not on extending Layer 2 services to external, non-VMM connected devices.
