Question 176 of 290 from exam 400-151: CCIE Data Center Written Exam


Which three components are involved in the Cisco vPath Solution? (Choose three.)



A. B. C. D. E. F.


The Cisco vPath solution is a virtual service insertion architecture that provides policy-based service insertion and chaining for virtual machines (VMs) and their associated networks. It consists of the following three primary components:

  1. Virtual Service Node (VSN): A VSN is a logical component that provides service chaining for traffic flowing through a virtual network. It allows you to insert network services (e.g., firewalls, load balancers, etc.) into the traffic path and define the order in which traffic flows through them.

  2. Virtual Ethernet Module (VEM): A VEM is a software module that runs on each hypervisor in a virtualized environment. It provides the virtual switch functionality for the virtual network and works with the VSN to implement service chaining.

  3. Virtual Supervisor Module (VSM): A VSM is a logical component that provides centralized management and control for the VSNs and VEMs in the virtualized environment. It allows administrators to define service policies, configure service insertion points, and monitor service performance.

Option B, the Application Policy Infrastructure Controller (APIC), is not directly related to vPath solution. However, it is a central management and automation component of the Cisco Application Centric Infrastructure (ACI), which is a related solution that provides policy-based automation and orchestration for both physical and virtual environments.

Option E, a leaf, is a component of the ACI fabric that provides connectivity to endpoints in the fabric and serves as a gateway to external networks. It is not directly related to the vPath solution.

Option F, a service graph, is a construct in ACI that defines the flow of traffic through a set of services, including both physical and virtual services. While it is related to service chaining, it is not a component of the vPath solution itself.

Therefore, the correct options for the components involved in the Cisco vPath Solution are A (VSM), C (VEM), and D (Virtual Service Node).
