In ACI (Application Centric Infrastructure) Fabric, integrating Layer 4-7 services is achieved through the use of Service Graphs. These Service Graphs are built using cluster interfaces, which are logical interfaces that group physical interfaces on the device.

When integrating a Layer 4-7 device in an ACI Fabric, two cluster interface types are valid:

  1. Inside: The inside interface is used for traffic that flows from the Fabric Access Layer to the Layer 4-7 device. This interface type is used for devices that provide services such as load balancing, firewalls, and intrusion prevention systems.

  2. Outside: The outside interface is used for traffic that flows from the Layer 4-7 device to the Fabric Access Layer. This interface type is used for devices that consume services such as servers and storage systems.

The other interface types listed in the answer options are not valid when integrating a Layer 4-7 device in an ACI Fabric:

  • Control interfaces are used for communication between the APIC (Application Policy Infrastructure Controller) and the device, and are not used for data traffic.
  • Provider and consumer interfaces are used for communication between EPGs (End Point Groups) within the Fabric, and are not used for integration with Layer 4-7 services.

Therefore, the correct answers are E. Inside and B. Outside.
