During a requirements gathering workshop to design a physical to virtual migration, the customer provides the following information:
- There is no physical firewall in the data center with no anticipated plans for a future network refresh.
- 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.
Which recommendation should the architect make to address the customer requirement with regard to virtual networking?
