Advanced Design VMware NSX-T Data Center Questions and Answers

Question 1

An architect is helping an organization with the Physical Design of an NSX-T Data Center solution.This information was gathered during a workshop about ESXi Host networking:

  • A total of 50 ESXi hosts to be configured as Transport Nodes.
  • All ESXi hosts have a dedicated 2 × Intel 10Gbps Physical Network adapter for the Overlay Traffic.

To achieve low latency, high throughput, redundancy, and performance, which two NIC teaming policies should the architect recommend? (Choose two.)

Options:

A.

Load Balance Source MAC

B.

Load Balance Port ID

C.

Load Balance Source

D.

Load Balance Source Port ID

E.

Failover Order

Question 2

An architect is helping an organization with the Logical Design of an NSX-T Data Center solution.During discussions about centralized services NAT running on Tier-1 or Tier-0 Gateway, the customer made these requests:

  • Services contain stateful services.
  • Services should be in high availability mode.

Which two selections should the architect include in their design? (Choose two.)

Options:

A.

An active/active model should be used.

B.

Use Reflexive NAT on the uplink interface.

C.

DNAT should be applied on the uplink interface.

D.

Mix stateful and stateless NAT rules on the same gateway.

E.

The high availability mode supported is only Active-Standby.

Question 3

A customer has a requirement to implement a next generation firewall (NGFW) to improve security network introspection. The customer wants to apply the NGFW to all workloads exposed both internally and externally. The customer wants the NGFW to work seamlessly with NSX-T Data Center and vSphere.

Which solution should be recommended to the customer? (Choose the best answer.)

Options:

A.

Use network introspection only on the external workloads and use NSX DFW for internal workloads.

B.

Apply the NGFW on bare metal hosts which will offer better performance of inline network introspection.

C.

Apply the NGFW to internal and external workloads for increased protection and use NSX-T Data Center with Federation to set network policies.

D.

Use NSX-T Data Center leveraged with NSX Intelligence to protect all workloads at the network inspection level.

Question 4

Which two VMware recommendations should an architect follow when configuring top of rack (ToR) switches in an NSX-T Data Center environment? (Choose two.)

Options:

A.

Use only IPv4 addressing in all deployments.

B.

Configure redundant physical switches to enhance availability.

C.

Configure switch ports that connect to ESXi host manually as trunk ports.

D.

Configure switch ports with a Dynamic Trunking Protocol.

E.

Modify the Spanning Tree Protocol to increase the time to transition to the forwarding state.

Question 5

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

This information was gathered during a workshop:

  • Migrating existing data center to KVM hosts.
  • Redundancy and high availability are required.
  • No component can be a single point of failure.

Which selection should the architect recommend? (Choose the best answer.)

Options:

A.

Linux Bridge redundancy with Active/Active Mode and multiple pNICs with necessary binding

B.

Linux Bridge redundancy with Active/Active Mode and single pNIC with static binding

C.

vSS/vDS in Active/Standby Mode with necessary binding

D.

vSS/vDS in Active/Active Mode with necessary pNICS and required binding modes

Question 6

Which selection is associated with the Review Task of the Engagement Lifecycle? (Choose the best answer.)

Options:

A.

Gather and document requirements, assumptions, and constraints.

B.

Build, deploy, implement, and test the design.

C.

Measure performance against customer’s objective.

D.

Create and document the logical and physical design.

Question 7

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.)

Options:

A.

Network I/O Control Profiles

B.

LLDP Profile

C.

LAG Uplink Profile

D.

Transport Node Profiles

Question 8

A Solutions Architect is assisting a service provider with designing an NSX-T Data Center solution for these environments:

Virtual Data Center to Virtual Data Center connectivity

Tenant workload on-boarding to Virtual Data Centers.

These requirements must be met:

  • scalability across 5 data centers
  • all sites have a latency of 180ms
  • MTU between sites is 1800
  • bandwidth is 100Mbps between sites
  • multi-tenancy

Which two selections should the Solutions Architect propose to the service provider? (Choose two.)

Options:

A.

Configure Remote TEPs for stretching network services between Virtual Data Centers.

B.

Utilize SSL VPN for workloads on-boarding from on-premises to Virtual Data Centers.

C.

Configure IPSec VPN for Tenant T0 gateways for Virtual Data Centers connectivity

D.

Configure IPSec VPN for Tenant T1 gateways for Virtual Data Centers connectivity.

E.

Utilize L2 VPN for workloads on-boarding from on-premises to Virtual Data Centers.
