VMware Exam 3V0-42.23 Topic 1 Question 3 Discussion

Advantages of a Centralized NSX Gateway Architecture (Correct Answer - D):

Scalability:

A centralized Tier-0 Gateway allows for consistent external connectivity across multiple NSX instances.

Redundancy:

Active-Active and Active-Standby configurations provide high availability (HA).

Faster Failover:

BGP/OSPF dynamic routing ensures rapid recovery in case of gateway failure.

Incorrect Options:

(A - Load Balancing & Troubleshooting):

Load balancing is handled by NSX Advanced Load Balancer, not centralized gateways.

(B - Simplified Network Design & Security):

While security improves, this answer misses key benefits like failover and redundancy.

(C - Network Visibility & Application Performance):

Visibility and performance depend on monitoring tools, not just gateway centralization.
