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

According to the VMware NSX 4.x Professional documents and tutorials, an NSX Manager is a standalone appliance that hosts the API services, the management plane, control plane, and policy management. The NSX Manager has three built-in roles: policy, manager, and controller2. The policy role handles the declarative configuration of the system and translates it into desired state for the manager role. The manager role receives and validates the configuration from the policy role and stores it in a distributed persistent database. The manager role also publishes the configuration to the central control plane. The controller role implements the central control plane that computes the network state based on the configuration and topology information3. The other roles (master, cloud, and zookeeper) are not valid NSX Manager roles.

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

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:
