Implementing Cisco Application Centric Infrastructure (DCACI) — Question 99

When does the Cisco ACI leaf learn a source IP or MAC as a remote endpoint?

Answer options

• A. When VXLAN traffic arrives on a leaf fabric port from the spine and outer source IP is in the Layer 3 Out EPG subnet range.
• B. When VXLAN traffic arrives on a leaf fabric port from the spine and outer source IP is in the bridge domain subnets range.
• C. When VXLAN traffic arrives on a leaf fabric port from the spine and inner source IP is in the Layer 3 Out EPG subnet range.
• D. When VXLAN traffic arrives on a leaf fabric port from the spine and inner source IP is in the bridge domain subnets range.

Correct answer: D

Explanation

The correct answer is D because the Cisco ACI leaf learns a remote endpoint when the inner source IP is in the bridge domain subnets range. Options A and B are incorrect as they refer to the outer source IP, which is not relevant for learning remote endpoints in this context. Option C is also incorrect because it refers to the Layer 3 Out EPG subnet range instead of the bridge domain subnets range.
