Physical Leaf Interface Configuration


Which two statements about the physical leaf interface configuration are true? (Choose two.)



Click on the arrows to vote for the correct answer

A. B. C. D. E.


A. When not configured, the default AEP information displayed on an interface defaults to the system-defined AEP.

This statement is true. AEP (Attachable Entity Profile) is used to apply consistent network policies to endpoints. If an interface is not explicitly configured with AEP information, it will inherit the system-defined AEP by default.

B. A port connected to an APIC has usage type of EPG, Infra, and Controller.

This statement is also true. The APIC (Application Policy Infrastructure Controller) is a key component of Cisco ACI (Application Centric Infrastructure) and connects to leaf switches. Ports connected to the APIC have multiple usage types: EPG (End Point Group) for communication with endpoints, Infra for communication with infrastructure services, and Controller for communication with the APIC itself.

C. The administrative port layer state can be Switched, Routed, or P2P.

This statement is incorrect. The administrative port layer state refers to the layer at which the switch will operate the port. The options are Layer 2 (Switched), Layer 3 (Routed), or Layer 1 (P2P), not Switched, Routed, or P2P.

D. Auto Mdix mode detects the cable connection type and configures the connection appropriately.

This statement is true. Auto Mdix (Automatic Medium-Dependent Interface Crossover) is a feature that automatically detects the cable type (straight-through or crossover) and configures the connection appropriately. This feature helps simplify network administration by eliminating the need to manually configure cables.

E. The port usage type is "Blacklist" by default.

This statement is incorrect. The default port usage type is "Not Configured". Ports can be configured with a usage type of Blacklist to prevent traffic from certain endpoints, but this is not the default behavior.
