New ESXi hosts are procured in a data center compute expansion project. An engineer must update the configuration on the Cisco APIC controllers to support the addition of the new servers to the existing VMM domain. Which action should be taken to support this change?

Question

Accepted Answer

D. Map the leaf interface selector to the AEP that is associated with the VMM domain. To connect new ESXi hosts to an existing VMM domain in Cisco ACI, the physical interfaces on the leaf switches connected to these hosts must be properly configured within the fabric access policy. This is achieved by creating or updating a leaf interface selector (which defines the specific port or port channel) and associating it with the Attachable Access Entity Profile (AEP) that is already linked to the VMM domain, allowing the fabric to extend network connectivity to the new servers.

Answer

A. Create a range of internal VLANs in the associated VLAN pool. While VLAN pools are used by VMM domains, simply creating new VLAN ranges doesn't directly connect new hosts; the existing VMM domain should already have a sufficient VLAN pool.

Answer

B. Set the encapsulation mode as VXLAN. The encapsulation mode (VXLAN or VLAN) is typically set at the VMM domain or bridge domain level and doesn't directly configure physical host connectivity for new servers.

Answer

C. Enable infrastructure VLAN in the associated AEP. The infrastructure VLAN is primarily used for APIC-managed fabric internal communication and is not enabled per AEP for connecting new compute hosts to a VMM domain.
