Question #14
What are the benefits of a centralized gateway architecture in NSX?
- A . Better load balancing, easier troubleshooting, and lower hardware costs
- B . Simplified network design, reduced network latency, and improved security
- C . Better application performance, improved network visibility, and easier management
- D . Improved scalability, increased redundancy, and faster failover times
Correct Answer: D
D
Explanation:
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.

Question #15
A global logistics company is planning to expand its operations to multiple locations across continents. Their existing on-premises network is unable to scale to meet the demands of the growing number of sites and the increasing volume of East-West traffic within their data center. The company has chosen VMware NSX as their preferred network virtualization platform, aiming to simplify network management and improve intra-data center routing.
Which of the following would be part of the optimal recommended design?
- A . Deploy NSX and use Centralized Service Ports to handle East-West routing within the data center.
- B . Deploy NSX with Aria Operations for Networks to handle North-South routing within the data center.
- C . Deploy NSX with Tier-1 Gateways to handle East-West routing within the data center.
- D . Deploy NSX with Tier-0 Gateways to handle North-South routing within the data center.
Correct Answer: C
C
Explanation:
Tier-1 Gateways for East-West Traffic (Correct Answer – C):
East-West traffic refers to communication within the data center (e.g., between workloads).
Tier-1 Gateways are optimized for East-West routing, ensuring efficient intra-data center traffic handling.
This minimizes unnecessary traffic to external routers, reducing latency and improving performance.
Incorrect Options:
(A – Centralized Service Ports for East-West Routing):
Centralized Service Ports (CSPs) are used for stateful services, not for general East-West routing.
(B – Aria Operations for Networks for North-South Routing):
Aria Operations for Networks (formerly vRealize Network Insight) is a monitoring and analytics tool, not a routing solution.
(D – Tier-0 for East-West Routing):
Tier-0 Gateways handle North-South routing (external connectivity), not East-West traffic.
