1. NSX and Multi-Data Center/Cloud Applications
When designing anNSX architecture for highly distributed applications, key concerns include:
* High availability (HA)across multiple locations.
* Load balancingtraffic efficiently to prevent bottlenecks.
* Optimized North-South and East-West traffic flowto minimize latency.
2. Why Advanced Load Balancer (Avi) is the Best Choice (Correct Answer - D)
* NSX Advanced Load Balancer (Avi)isdesigned for multi-cloud environments, enablingglobal application deliveryacrossdata centers and public clouds.
* It provides intelligent traffic distribution across different locations, ensuringoptimal application performance and resilience.
* Supports active-active, active-passive, and disaster recovery failover scenarios.
* Key Features Include:
* Global Load Balancing (GSLB)for cross-data center traffic management.
* L7 Application Load Balancing with WAFfor security and optimization.
* Auto-scaling capabilitiesto adjust based on demand.
3. Why Other Options are Incorrect
* (A - NAT):
* NAT translates IP addresses, but itdoes not optimize performance or manage traffic loads across data centers.
* (B - VPNs):
* VPNs provide secure connectivity, but they donot distribute application traffic intelligently.
* (C - Distributed Firewall):
* DFW is critical for security and segmentationbutdoes not balance application traffic.
4. Key Design Considerations for NSX Advanced Load Balancer
* Ensure Edge nodes are sized properly to handle high volumes of traffic.
* Configure GSLB if using multi-cloud applicationsto route users to the closest available data center.
* Monitor performance metrics such as latency, requests per second (RPS), and failover handling.
