NSX Control Plane Functions

AB.

The NSX Control Plane is responsible for managing the network virtualization functions of NSX-T Data Center. It is responsible for two main functions, as follows:

1. Propagate Topology Information: One of the primary functions of the NSX Control Plane is to propagate topology information across the NSX-T infrastructure. This includes information about virtual switches, logical routers, distributed logical routers, and service gateways. This information is used by the forwarding engines to create and maintain forwarding tables, which are used to forward traffic between virtual machines and physical networks.

2. Push Stateless Configurations to Forwarding Engines: Another important function of the NSX Control Plane is to push stateless configurations to forwarding engines. Stateless configurations include firewall rules, load balancing rules, NAT rules, and other settings that do not require the forwarding engines to maintain state information. The forwarding engines receive these configurations from the NSX Control Plane and use them to process traffic passing through the network.

Therefore, the correct answers to the question are A (push stateless configurations to forwarding engines) and B (propagate topology information).

The other options are incorrect because:

• Option C (receive and validate configuration from NSX Policy) refers to the NSX Policy Manager, which is a component of the NSX Management Plane, not the NSX Control Plane.
• Option D (host API services) refers to the NSX API server, which is a component of the NSX Management Plane, not the NSX Control Plane.
• Option E (maintain packet-level statistics) is a function of the NSX Data Plane, not the NSX Control Plane.
