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.

The answer is A. SR is instantiated and automatically connected with DR.

SR stands for Service Router and DR stands for Distributed Router. They are components of the NSX Edge node that provide different functions1

The SR is responsible for providing stateful services such as NAT, firewall, load balancing, VPN, and DHCP. The DR is responsible for providing distributed routing and switching between logical segments and the physical network1

When a stateful service is enabled for the first time on a Tier-0 Gateway, the NSX Edge node automatically creates an SR instance and connects it with the existing DR instance. This allows the stateful service to be applied to the traffic that passes through the SR before reaching the DR2

According to the VMware NSX 4.x Professional Exam Guide, understanding the SR and DR components and their functions is one of the exam objectives3

To learn more about the SR and DR components and how they work on the NSX Edge node, you can refer to the following resources:

• VMware NSX Documentation: NSX Edge Components 1
• VMware NSX 4.x Professional: NSX Edge Architecture
• VMware NSX 4.x Professional: NSX Edge Routing

The CLI command on NSX Manager and NSX Edge that is used to change NTP settings is set ntp-server. This command allows the user to configure one or more NTP servers for time synchronization12. The other options are incorrect because they are not valid CLI commands for changing NTP settings. The get timezone and set timezone commands are used to display and configure the timezone of the system1. The get time-server command is used to display the current time server configuration1. There are no CLI commands for using RADIUS or BootP for NTP settings. References: NSX-T Command-Line Interface Reference, vSphere ESXi 7.0 U3 and later versions NTP configuration steps
