Increase MTU & Multi-TEP (Correct Answer - B):

Increasing the MTU size (Jumbo Frames 1600-9000 bytes) helps reduce fragmentation and improve Geneve performance.

Multi-TEP (Tunnel Endpoints) enables load balancing of overlay traffic across multiple NICs, enhancing throughput.

High-speed NICs (25G/40G/100G) improve data plane performance by reducing packet processing overhead.

Incorrect Options:

(A - MTU Increase But Single TEP):

A single TEP creates a bottleneck as all overlay traffic is routed through one NIC.

(C - Decrease MTU & Use Single TEP):

Reducing MTU increases fragmentation, negatively impacting performance.

(D - Keep MTU & Reduce NIC Speed):

Slower NIC speeds increase latency and reduce throughput, which contradicts the goal.

Common Constraints in NSX Design (Correct Answers - A, B):

Network Bandwidth: Limited bandwidth can impact Geneve overlay performance, East-West traffic flow, and multi-site connectivity.

Available Hardware: The number and type of ESXi hosts, NICs, and Edge nodes affect performance, scalability, and HA capabilities.

Incorrect Options:

(C - Security Requirements):

Security requirements are design considerations, not constraints.

(D - Product Knowledge):

Product knowledge affects deployment efficiency, but is not a technical constraint.

NSX Federation for Cross-Site Management (Correct Answer - B):

NSX Federation provides centralized security and network management across multiple locations.

Distributed Firewall (DFW) ensures per-tenant segmentation, enhancing multi-tenancy security.

Tier-0 Gateway handles global routing, ensuring consistent cross-site connectivity.

Incorrect Options:

(A - NSX Multi-Site Instead of Federation):

NSX Multi-Site provides disaster recovery, but NSX Federation offers centralized policy enforcement.

(C - Gateway Firewall Instead of DFW):

DFW is required for intra-tenant segmentation, whereas Gateway Firewall handles North-South traffic.

(D - Tier-1 Instead of Tier-0 for Multi-Tenancy):

Multi-tenancy is handled at the Tier-0 level, not Tier-1.
