A financial institution is looking to improve their existing virtual environment with a focus on increasing security to protect sensitive data. The firm has a single data center and is concerned about lateral movement of threats within the network. They are particularly interested in utilizing VMware NSX to implement segmentation and adopt a Zero Trust security model.
Which of the following would be part of the optimal recommended design, utilizing a firewall?
- A . Implement NSX with Gateway Firewall with each application deployed on its own Overlay Network.
- B . Implement NSX with a Distributed Firewall with each application deployed on its own Overlay Network.
- C . Implement NSX with Gateway Firewall with the use of VLAN-backed virtual standard switch for network segmentation.
- D . Implement NSX with a Distributed Firewall with the use of VLAN-backed virtual standard switch for network segmentation.
B
Explanation:
NSX Distributed Firewall for Zero Trust Security (Correct Answer – B):
NSX Distributed Firewall (DFW) provides micro-segmentation at the vNIC level to enforce Zero Trust policies.
Each application runs on its own NSX Overlay Network, preventing lateral movement of threats.
Application-specific segmentation ensures granular control and compliance with regulatory standards (PCI-DSS, GDPR).
Incorrect Options:
(A – Gateway Firewall on Overlay Networks):
The Gateway Firewall controls North-South traffic, but DFW is required for East-West security.
(C & D – VLAN-Backed Networks Instead of Overlays):
VLANs are limited in scalability compared to overlay networks, reducing segmentation flexibility.
