Which three choices are part of a Design Approach when discussing design alternatives and their effects? (Choose three.)
Key Design Considerations (Correct Answers - B, C, E):
Budget: Determines hardware, licensing, and NSX deployment costs.
Cost: Affects NSX scalability, high availability, and feature selection.
Performance: Defines bandwidth requirements, throughput, and overlay network efficiency.
Incorrect Options:
(A - Backup):
Backup is an operational consideration, not a design alternative.
(D - Knowledge):
While engineers need NSX knowledge, this is not a technical design factor.
(F - Security):
Security is important but should be integrated into budget and performance discussions.

NSX-T Design and Architecture Best Practices
VMware Validated Design (VVD) for NSX
A Solutions Architect is helping an organization with the multi-location design of an NSX solution.
This information was gathered during a design workshop:
No Jumbo Frames allowed on the WAN
Simple DR solution with no fabric nor vCenter requirements
GDPR requirements (Management Plane distributed in each location)
What should the architect recommend be configured in the NSX environment?
NSX Multisite for Compliance & Distributed Management (Correct Answer - B):
NSX Multisite supports deployments without requiring centralized management (NSX Federation).
Since GDPR requires data locality, separate NSX Managers per site help comply with data protection laws.
No Jumbo Frames requirement indicates transport overlays are not required, making Multisite a better fit than NSX Federation.
Incorrect Options:
(A - NSX Federation):
Federation requires Global Manager, which is not needed for a simple DR solution.
(C - Active/Active Tier-0 Gateway):
Active/Active Tier-0 is a routing decision, not a multi-location design strategy.
(D - IPSec VPN):
IPSec VPN is not sufficient for multi-site management.

What is the effect of stateful services placement on NSX Edge design?
Impact of Stateful Services on NSX Edge Cluster (Correct Answer - B):
Stateful services (NAT, FW, LB, VPN) require additional processing power, impacting Edge node performance.
More stateful services means higher CPU and memory utilization, affecting scalability.
Edge Cluster design must balance stateful workloads to avoid performance degradation.
Incorrect Options:
(A - Stateless services cannot run with stateful applications):
Stateful and stateless services can coexist on NSX Edge, but require careful placement.
(C - Reduces the need for load balancing):
Load balancing is still needed, even if stateful services exist.
(D - Determines complexity of Edge cluster size):
While it adds complexity, the primary impact is on performance and scalability.

A Solutions Architect is working with a customer who wants to extend their traditional Telco IP/MPLS core network to an NFV cloud.
Which NSX feature can be recommended by the architect?
EVPN for Telco and NFV Cloud Extensions (Correct Answer - B):
Ethernet VPN (EVPN) allows seamless integration between MPLS-based networks and NSX overlays.
Supports L2/L3 VPN, VLAN stretching, and multi-data center deployments.
Ideal for Telco NFV (Network Function Virtualization) clouds that require scalable, multi-tenant networking.
Incorrect Options:
(A - BGP):
BGP (Border Gateway Protocol) is used for dynamic routing, but EVPN is specifically designed for Telco MPLS integration.
(C - Load Balancer):
Load Balancers improve application availability, but do not provide Telco network extension.
(D - Distributed IDS):
IDS/IPS secures workloads, but is not relevant for NFV cloud connectivity.

Telco NFV Cloud Deployment with VMware NSX
A customer is planning to migrate their current legacy networking infrastructure to a virtual environment, aiming to increase network flexibility and agility.
The customer is particularly interested in:
Multi-tenancy
Segmentation
Disaster recovery
The customer's current data center is split across three geographical locations, and they want a solution that offers cross-site management and ensures seamless network connectivity.
Which of the following would be part of the optimal recommended design?
1. Why NSX Federation is the Best Choice (Correct Answer - B)
NSX Federation enables centralized management of multiple NSX deployments across different sites.
Distributed Firewall (DFW) ensures security segmentation per tenant, even across data centers.
Tier-0 Gateway provides global routing for multi-tenancy, ensuring efficient traffic flow between sites.
2. Why Other Options are Incorrect
(A - NSX Multi-Site Instead of Federation):
NSX Multi-Site only provides disaster recovery capabilities, not global policy enforcement.
(C - Gateway Firewall Instead of Distributed Firewall):
Gateway Firewalls secure North-South traffic but do not provide per-tenant segmentation at the workload level.
(D - Tier-1 Instead of Tier-0 for Multi-Tenancy):
Multi-tenancy is best implemented at the Tier-0 level to handle global routing efficiently.
3. NSX Federation Best Practices for Multi-Tenancy and DR
Deploy a Global Manager (GM) for centralized security policy enforcement.
Ensure Tier-0 Gateway is configured in Active-Active mode for scalability.
Use BGP for dynamic routing between data centers.
