2V0-41.23 Exam Dumps : VMware NSX 4.x Professional

According to the VMware NSX Documentation, these are two of the ways that you can use to configure Distributed Firewall on VDS:

• NSX API: This is a RESTful API that allows you to programmatically configure and manage Distributed Firewall on VDS using HTTP methods and JSON payloads. You can use tools such as Postman or curl to send API requests to the NSX Manager node.
• NSX UI: This is a graphical user interface that allows you to configure and manage Distributed Firewall on VDS using menus, tabs, buttons, and forms. You can access the NSX UI by logging in to the NSX Manager node using a web browser.

Distributed Firewall on VDS is a feature of NSX-T Data Center that allows users to install Distributed Security for vSphere Distributed Switch (VDS) without the need to deploy an NSX Virtual Distributed Switch (N-VDS). This feature provides NSX security capabilities such as Distributed Firewall (DFW), Distributed IDS/IPS, Identity Firewall, L7 App ID, FQDN Filtering, NSX Intelligence, and NSX Malware Prevention. To enable this feature, the following requirements must be met in the environment:

• The NSX version must be 3.2 and later1. This is the minimum version that supports Distributed Security for VDS.
• The VDS version must be 6.6.0 and later1. This is the minimum version that supports the NSX host preparation operation that activates the DFW with the default rule set to allow.

The host switch modes determine how the NSX network and security stack is allocated on the underlying host CPU or DPU. There are two supported host switch modes: Enhanced Datapath and Standard Datapath1. Enhanced Datapath mode leverages the DPU to offload the NSX datapath processing from the host CPU, while Standard Datapath mode uses the host CPU for the NSX datapath processing1. DPDK Datapath, Overlay Datapath, and Secure Datapath are not valid host switch modes for NSX 4.x. References: NSX Features
