1. Importance of NSX Edge for North-South Traffic

NSX Edge nodes provide routing, NAT, firewall, and load balancing services for North-South traffic(external connectivity).

Active-Active Tier-0 Gateway provides maximum performance and resiliencyfor high traffic volume.

2. Why Active-Active Tier-0 with Multiple Edge Nodes is the Best Choice (D)

Supports Equal-Cost Multi-Path (ECMP) routing, distributing North-South traffic across multiple paths.

Provides better scalability and performance than Active-Standby mode.

Ideal for high-volume applications like e-commerce sitesthat require low-latency, high-throughput connections.

3. Why Other Options are Incorrect

(A - Single NSX Edge Node):

Single Edge Nodes introduce a single point of failure.

(B - Using a Physical Router for East-West Routing):

NSX handles East-West traffic internally using Distributed Routing.

(C - Active-Standby Tier-0 Gateway):

Active-Standby mode does not provide load balancing across multiple nodes.

4. NSX Edge and Tier-0 Gateway Design Considerations

Ensure sufficient bandwidth allocation for North-South traffic.

Use BGP or OSPF for dynamic route advertisement.

Configure ECMP for efficient multi-path forwarding.
