Multi-Tier Architecture for Stateful Services (Correct Answer - A):

Multi-tier NSX architecture (T0-T1)providesgranular traffic controlby allowingseparation of stateful services(e.g., NAT, Load Balancer, Firewall).

Itoptimizes traffic flowbetweendifferent application tiers, preventingunnecessary stateful service processingat theTier-0 Gateway.

Incorrect Options:

(B - Better Performance and Scalability):

Performancedepends on deployment designrather than the number of tiers.

(C - Simplifies Stateful Service Deployment):

Stateful services still require specific placement, making configuration morestructured, not necessarily simpler.

(D - Reduces NSX Edge Nodes Required):

Edge node requirements depend on workload size, not the number of tiers.
