Leaf Access Port Policy Group Configuration
Question
An engineer needs to deploy a leaf access port policy group in ACI Fabric to support the following requirements: -> Control the amount of application data flowing into the system -> Allow the newly connected device to auto-negotiate link speed with the leaf switch Which two ACI policies must be configured to achieve these requirements? (Choose two.)

L2 Interface Policy: The L2 interface policy is used to configure the Layer 2 port-level settings, such as port speed, duplex, flow control, and other features. In this case, the engineer needs to allow the newly connected device to auto-negotiate link speed with the leaf switch, which means that the L2 interface policy must be configured with the auto-negotiation option enabled. This will allow the device to automatically determine the best link speed and duplex setting based on the capabilities of both the device and the switch.
Ingress Data Plane Policing Policy: The Ingress Data Plane Policing Policy is used to control the amount of traffic that can be sent to a port or a group of ports. In this case, the engineer needs to control the amount of application data flowing into the system, which means that the Ingress Data Plane Policing Policy must be configured to limit the amount of traffic that can be sent to the leaf access port policy group. This can be achieved by configuring the policy with appropriate bandwidth limits, burst sizes, and actions to take when the limit is exceeded.
Therefore, options B (L2 interface policy) and D (Ingress Data Plane Policing Policy) are the correct answers to this question. Options A, C, and E are incorrect as they do not relate to the requirements mentioned in the question.
