Question #21

Which three choices are part of a Design Approach when discussing design alternatives and their effects? (Choose three.)

A . Backup
B . Budget
C . Cost
D . Knowledge
E . Performance
F . Security

Reveal Solution Hide Solution

Correct Answer: B, C, E
B, C, E

Explanation:

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.

Question #24

A Network Architect has been tasked with recommending a solution for traffic management to a client. The client has asked about the differences between IP hash and LACP for link integration.

Which of the following is an accurate description of the differences?

A . IP hash uses a control protocol to negotiate link aggregation, while LACP uses a hash function to distribute traffic based on the source and destination IP addresses.
B . LACP uses a hash function to distribute traffic based on the source and destination IP addresses, while IP hash uses a control protocol to negotiate link aggregation.
C . IP hash uses a hash function to distribute traffic based on the source and destination IP addresses,
while LACP uses a control protocol to negotiate link aggregation.
D . LACP uses a control protocol to negotiate link aggregation, while IP hash uses a hash function to distribute traffic based on the source and destination MAC addresses.

Question #25

How can a multi-tier architecture benefit a customer’s design?

A . It offers better control over the placement of stateful services.
B . It provides a cost-effective solution for simple networks.
C . It simplifies the network topology by consolidating all services into a single tier.
D . It eliminates the need for EVPN in the network design.

Correct Answer: A
A

Explanation:

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

In NSX-T, a multi-tier architecture consists of Tier-0 (T0) and Tier-1 (T1) Gateways, allowing better control and placement of stateful services such as:

Load Balancers (LBs)

NAT (Network Address Translation)

Firewall Rules (DFW, Gateway FW)

VPN Services

Tier-1 Gateways can be configured to handle stateful services, while Tier-0 Gateways focus on routing North-South traffic efficiently.

Incorrect Options:

(B – Cost-Effective for Simple Networks):

Multi-tier architecture is not necessarily cost-effective for simple networks. Instead, a single-tier deployment might be more suitable.

(C – Simplifies Network Topology by Consolidation):

Multi-tier segregates services rather than consolidating them. It separates East-West and North-South traffic flows for better performance.

(D – Eliminates the Need for EVPN):

Ethernet VPN (EVPN) is a control plane solution for VXLAN overlay networks, mainly used in multi-site or multi-data center deployments. It is independent of the multi-tier architecture.

Question #27

A large multinational company is expanding its data center due to increased demand for online services.

The company is considering shifting from an NSX Edge VM design to a bare-metal NSX Edge design to accommodate new hardware acquisitions and maximize performance.

Which is a potential benefit for the company in shifting from an NSX Edge VM design to a bare-metal NSX Edge design?

A . It will maximize performance by reducing virtualization overhead.
B . It will allow for the implementation of more VLANs.
C . It will automatically distribute stateful services across Edge nodes.
D . It will eliminate the need for stateful services.

Reveal Solution Hide Solution

Correct Answer: A
A

Explanation:

Performance Benefits of Bare-Metal NSX Edge (Correct Answer – A):

Bare-metal NSX Edge Nodes provide higher performance by eliminating the virtualization overhead associated with Edge VMs running inside ESXi/KVM hosts.

This increases throughput and reduces latency, making it ideal for high-bandwidth applications (e.g., Load Balancing, VPN, and NAT).

Incorrect Options:

(B – More VLANs):

The number of VLANs is not limited by the NSX Edge type. VLAN scalability depends on physical network design.

(C – Automatic Stateful Service Distribution):

Stateful services (NAT, FW, LB, VPN) do not auto-distribute. Stateful HA must be manually configured.

(D – Eliminates Stateful Services):

Stateful services (e.g., NAT, Load Balancer, Firewall) are still required, regardless of Edge deployment mode.
