Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 219

An engineer must allow communication between the APIC controller and an OpenStack OpFlex agent. The agent is running on a compute node directly plugged to a Cisco ACI leaf switch. The engineer must enable and extend Infra VLAN on the port facing the compute and extend the Infra VLAN to the host. Which action must be taken to meet these requirements?

Answer options

• A. Add the infra VLAN via the VMM domain.
• B. Enable the Infra VLAN on the Interface Profile policy.
• C. Enable the Infra VLAN on the Attachable Access Entity Profile.
• D. Add the infra VLAN via the physical domain.

Correct answer: C

Explanation

The correct answer is C because enabling the Infra VLAN on the Attachable Access Entity Profile allows the VLAN to be properly extended to the compute node. Option A is incorrect as adding the VLAN via the VMM domain does not directly affect the connection to the compute node. Option B is also wrong since the Interface Profile policy does not manage extending the Infra VLAN to the host. Option D is not applicable because the physical domain does not handle VLAN assignments in this context.
