Question 1

An architect is helping an organization with the Conceptual Design of an NSX-T Data Center solution. Which three selections are requirements documented by an architect? (Choose three.)

AAggregate N-S throughput at any given time should be at least 10G.

BAll traffic should recover in the event of Host/Rack/ToR failure.

CHardware is 5 years old and new hardware is already purchased.

DSAN storage has enough capacity to build the new infrastructure.

EBusiness critical applications should have an SLA of 99.99%.

FThe Development Team are heavy on API usage.

Answer : A, B, E

Question 2

A customer wants to use ECMP to provide additional throughput and availability for their critical business applications. Some applications require load balancing for scale and availability.

Which two Edge design choices can an architect present to the customer? (Choose two.)

ACreate a Tier-0 gateway in Active/Standby mode and a Tier-1 gateway in Active/Standby mode.

BConfigure ECMP and Load Balancing on the Tier-0 gateway.

CCreate a Tier-0 gateway in Active/Active mode and a Tier-1 gateway in Active/Standby mode.

DCreate a Tier-0 gateway in Active/Standby mode.

EConfigure ECMP on the Tier-0 gateway and Load Balancing on the Tier-1 gateway.

Answer : C, E

Question 3

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 is a performance based SLA for East -- West traffic.

The business critical applications require prioritization of their traffic.

One of the services is a file share and has a high demand for bandwidth.

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

AReview average North/South traffic from the core switches and firewall.

BInclude a segment QoS profile and review the impact of utilizing this feature.

CMeet with the organization's application team to get additional information.

DMonitor East-West traffic throughout normal business cycles.

Answer : B

QoS provides high-quality and dedicated network performance for preferred traffic that requires high bandwidth. The QoS mechanism does this by prioritizing sufficient bandwidth, controlling latency and jitter, and reducing data loss for preferred packets even when there is a network congestion.

BPIM Dense Mode

CIGMPv2

DPIM Sparse mode

EIGMPv3

Answer : C, D

The following protocols are used to implement multicast in NSX-T Data Center 3.0>

Internet Group Management Protocol (IMGP)

- IGMPv2

- IGMP Snooping

Protocol-Independent Mutlicast (PIM)

- PIM Sparse Mode (PIM-SM)

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.)

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

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

CvSS/vDS in Active/Standby Mode with necessary binding

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

Answer : A

Question 6

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.)

AThere are applications which use IPv6 addressing.

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

CHosts can only be configured with two physical NICs.

DThe storage array has enough capacity to deploy NSX components.

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

Answer : A, B

Question 7

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.)

ADeploy a Tier-1 gateway and connect it to an Active/Active Tier-0 gateway with ECMP configured.

BDeploy an Active/Active Tier-0 gateway and configure ECMP.

CDeploy an Active/Standby Tier-0 gateway and configure ECMP.

DCreate two separate VLANs to connect the Tier-0 gateway upstream traffic and configure ECMP.

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.
