VMware Exam 3V0-42.23 Topic 5 Question 2 Discussion

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

Multi-tier NSX architecture (T0-T1) provides granular traffic control by allowing separation of stateful services (e.g., NAT, Load Balancer, Firewall).

It optimizes traffic flow between different application tiers, preventing unnecessary stateful service processing at the Tier-0 Gateway.

Incorrect Options:

(B - Better Performance and Scalability):

Performance depends on deployment design rather than the number of tiers.

(C - Simplifies Stateful Service Deployment):

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

(D - Reduces NSX Edge Nodes Required):

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