Which feature does Cisco VSG utilize to redirect traffic on Cisco Nexus 1000V Series Switch?

1. VPC

2. VDC

3. VEM

4. vPath

The correct answer is: vPath

Cisco VSG (Virtual Security Gateway) uses vPath as its key feature for redirecting traffic within the Cisco Nexus 1000V Series Switch. vPath is a virtualized function that allows for the dynamic redirection of traffic, enabling the seamless integration of security services into the virtualized data center environment. It essentially functions as a bypass mechanism that directs the traffic to the VSG’s virtual appliances for inspection and security processing. Implementing vPath allows for better scalability and flexibility as it adapts to the shifting workloads in virtual environments. Moreover, it provides an elegant way to incorporate various security policies and controls at the virtual network level without introducing significant overhead or disruption to the user experience. This alignment with virtualized infrastructure means that security can be integrated deeply into the fabric of the network, ensuring that all traffic can be monitored and controlled effectively. In contrast, the other options refer to different features that do not specifically relate to traffic redirection: VPC (Virtual Port Channel) focuses on link aggregation for enhanced redundancy and bandwidth, VDC (Virtual Device Context) is about partitioning a physical switch into multiple logical devices with separate resources, and VEM (Virtual Ethernet Module) is connected to the control plane but does not directly handle traffic redirection
