Which of the following of the main architectural component of Cisco ACI?

  • the APIC
  • a leaf switch
  • a CE network
  • a spine switch
Explanation:

The Cisco Application Policy Infrastructure Controller (APIC) is a means of managing the Cisco Application Centric Infrastructure (ACI); it is the main architectural component of Cisco ACI. A Cisco ACI architecture requires both the APIC and the spine switches and leaf switches of FabricPath to complete the architecture. The APIC communicates with the spine and leaf nodes and provides policy distribution as well as centralized management.
A leaf switch is not the main architectural component of Cisco ACI; a leaf switch is the Cisco FabricPath component that provides access layer connectivity. Cisco FabricPath is a means of constructing a scalable Open Systems Interconnection (OSI) networking model Layer 2 network from both Layer 2 and Layer 3 components. End hosts and classic Ethernet (CE) networks are typically directly connected to leaf switches by using edge ports.
A spine switch is not the main architectural component of Cisco ACI. Spine switches are the Cisco FabricPath component that form the backbone of the FabricPath’s switching fabric. Typically, leaf switches are connected to every spine switch along the backbone so that the spine switches provide connectivity between the leaf switches. Leaf switches connect to spine switches by using core ports.
A CE network, which is a traditional Ethernet network that uses Spanning Tree Protocol (STP) and transparent bridging, is not technically part of Cisco FabricPath. However, Cisco Nexus switches can connect to a CE network and Cisco FabricPath simultaneously.
