350-401 Question 92
Single answerAn enterprise network is using Cisco Nexus switches configured with virtual PortChannels (vPCs) for redundancy and high availability. The network administrator plans to implement virtual switching and has decided to use a Cisco Nexus 1000V Series switch for the virtualized environment. Which component is responsible for managing the control plane of the Cisco Nexus 1000V?
- A
Virtual Ethernet Module (VEM)
- B
Virtual Supervisor Module (VSM)
- C
Cisco UCS Fabric Interconnect
- D
ESXi vSwitch
Show answer and explanation
Correct answer: B
Explanation
The Cisco Nexus 1000V Series switch is a virtual switch designed for VMware vSphere and Microsoft Hyper-V environments. It consists of two main components: the Virtual Supervisor Module (VSM) and the Virtual Ethernet Module (VEM). The VSM is responsible for managing the control plane and configurations, while the VEM handles the data-plane operations on the hypervisor hosts. To implement virtual switching using Cisco Nexus 1000V, the VSM must be deployed to manage the environment effectively.
- A. Incorrect.
The Virtual Ethernet Module (VEM) is a component of Cisco Nexus 1000V, but it is responsible for data-plane operations and resides on the hypervisor hosts, not the control plane.
- B. Correct.
The Virtual Supervisor Module (VSM) is the control-plane component of the Cisco Nexus 1000V and is responsible for managing the configuration and control of the VEMs.
- C. Incorrect.
The Cisco UCS Fabric Interconnect is not part of the Cisco Nexus 1000V solution; it is part of Cisco UCS architecture for managing server hardware and connectivity.
- D. Incorrect.
The ESXi vSwitch is VMware's virtual switch and is unrelated to Cisco Nexus 1000V functionality.
