Question 1

Which NSX-T feature is used to allocate the network bandwidth to business-critical applications and to resolve situations where several types of traffic compete for common resources? (Choose the best answer.)



Answer : A

Use the Network I/O Control (NIOC) profile to allocate the network bandwidth to business-critical applications and to resolve situations where several types of traffic compete for common resources.

NIOC profile introduces a mechanism to reserve bandwidth for the system traffic based on the capacity of the physical adapters on a host. Version 3 of the Network I/O Control feature offers improved network resource reservation and allocation across the entire switch.

Network I/O Control version 3 for NSX-T Data Center supports the resource management of the system traffic related to virtual machines and to infrastructure services, such as vSphere Fault Tolerance. System traffic is strictly associated with an ESXi host.

Question 2

An architect is helping an organization with the Physical Design of an NSX-T Data Center solution.

This information was gathered during a workshop:

The company will use a Leaf and Spine physical network architecture with Layer 3 gateways for top of rack switches.

The company is planning to deploy 120 ESX hosts across 10 racks.

There will be a total of a 12 clusters where each cluster has one host per rack.

What should the architect recommend to allow applications to run on any host in the cluster? (Choose the best answer.)



Answer : A


Question 3

An architect is helping an organization with the Conceptual Design of an NSX-T Data Center solution. This information was gathered by the architect during the Discover Task of the Engagement Lifecycle:

There are applications which use IPv6 addressing.

Network administrators are not familiar with NSX-T Data Center solutions.

Hosts can only be configured with two physical NICs.

There is an existing management cluster to deploy the NSX-T components.

Dynamic routing should be configured between the physical and virtual network.

There is a storage array available to deploy NSX-T components.

Which two requirements were documented by the architect? (Choose two.)



Answer : A, B


Question 4

What is a design justification for a solution with 3 NSX Manager nodes deployed in a 4 ESXi cluster Management Cluster? (Choose the best answer.)



Answer : D


Question 5

An architect is helping an organization with the Logical Design of an NSX-T Data Center solution. This information was gathered during the Assessment Phase:

Maximum performance and availability is required between the physical and virtual network.

Load Balancing service is required for back-end web servers.

NAT is required.

Which selection should the architect include in their design? (Choose the best answer.)



Answer : A

LB must be attached to Tier-1 gateway. In a typical deployment, the Tier-1 gateway is connected to a Tier-0 gateway in active-active mode, and as we know just in Tier-0 is supported ECMP.


Question 6

An architect is helping an organization with the Logical Design of an NSX-T Data Center solution. This information was gathered during the Assessment Phase:

There isn't much budget available for a new off shore site.

The new site is decentralized and no communication with the main data center is required.

The design will need to cater for availability, upgrades, and failure scenarios.

N+1 must be maintained at all times.

Which three selections should the architect recommend in their design? (Choose three.)



Answer : B, D, E


Question 7

Which three IPv6 features are supported in an NSX-T Data Center design? (Choose three.)



Answer : B, C, E
