Question 12

DRAG DROP What order of steps is taken when using an NSX edge service gateway with proxy mode load balancing? https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/Dell_D-VXB-DY-A-24/page_37_img_1.jpg

Accepted Answer

Explanation: The order of steps taken when using an NSX edge service gateway with proxy mode load balancing is as follows: Client sends traffic to virtual IP address exposed by the load balancer. Load balancer performs address translation and sends traffic to server IP. Server replies by sending the traffic to the load balancer. Load balancer performs address translation and sends the traffic to client IP. The process begins with a client initiating communication by sending traffic to a virtual IP address, which is managed by the NSX edge service gateway functioning as a load balancer. Upon receiving the traffic, the load balancer translates this virtual IP address into one of the actual server IPs that it manages, effectively directing the client’s request to an appropriate server in its pool. The selected server processes this request and responds back, sending its reply to the load balancer rather than directly back to the client. Finally, once receiving this response from the server, the load balancer translates it from its own internal server IP back into what appears as a response from the original virtual IP address and forwards this response on to complete communication loop back at the client’s end. .
