During a requirements gathering workshop to design a physical to virtual migration, the customer provides the following information:

Leveraging the virtual infrastructure to mitigate the lack of network security must be addressed in the design.

All physical servers to be migrated exist on the same VLAN.

Suggested answer: C

Explanation:

In a vSphere distributed switch, by using the traffic filtering and marking policy, you can protect the virtual network from unwanted traffic and security attacks or apply a QoS tag to a certain type of traffic. The traffic filtering and marking policy represents an ordered set of network traffic rules for security and for QoS tagging of the data flow through the ports of a distributed switch. In general, a rule consists of a qualifier for traffic, and of an action for restricting or prioritizing the matching traffic.
