authentication must be performed by customer's existing SAML identity provider

MFA must be performed by administrator to gain access to NSX Manager

Which identity deployments would meet the customer's requirements? (Choose the best answer.)

ANSX Manager OAuth 2.0 registered to a 3-node Active Directory Federation Services cluster.

BNSX Manager OAuth 2.0 registered to a 2-node VMware Identity Manager cluster.

CNSX Manager OAuth 2.0 registered to a 2-node Active Directory Federation Services cluster

DNSX Manager OAuth 2.0 registered to a 3-node VMware Identity Manager cluster.

Question 2

A customer wants to place their NSX Managers in different subnets. Which would an architect recommend to support the request? (Choose the best answer.)

AUse a load balancer.

BUse round-robin DNS.

CUse NAT.

DUse a cluster Virtual IP.

Answer : A

An external load balancer can provide the following benefits:

Load balance across the NSX Managers.

The NSX Managers can be in different subnets.

Fast recovery time in the event of a Manager node failure.

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:

Existing hardware will be used in any design proposal.

Network bandwidth cannot be expanded.

Which concept of the Discover Task do these items belong to? (Choose the best answer.)

Aconstraint

Brequirement

Crisk

Dassumption

Answer : A

Question 4

An NSX-T architect is working with a customer who wants to improve performance and future-proof their workloads with a multi-site architecture.

A current-state analysis captured this information:

Latency between sites is 160ms.

Bandwidth is 2Gbps.

The MTU is 1600.

What two VMware design recommendations should the architect recommend to the organization to achieve future-proofing? (Choose two.)

AMTU is recommended to be 9000.

BMTU must be at least 1700.

CBandwidth must be at least 10Gbps.

DLatency RTT is acceptable.

ELatency must be less than 150ms.

Answer : A, E

As per VMware documentation: https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.0/administration/GUID-5D7E3D43-6497-4273-99C1-77613C36AD75.html

Requirements for Multisite Deployments

The bandwidth must be at least 1 Gbps and the latency (RTT) must be less than 150 ms.

MTU must be at least 1600. 9000 is recommended.

Requirements for Multisite Deployments

Inter-site Communication

- The bandwidth must be at least 1 Gbps and the latency (RTT) must be less than 150 ms.

- MTU must be at least 1600. 9000 is recommended.

NSX Manager Configuration

- Automatic backup when NSX-T Data Center configuration changes must be enabled.

- NSX Manager must be set up to use FQDN.

Data Plane Recovery

- The same internet provider must be used if public IP addresses are exposed through services such as NAT or load balancer.

- The HA mode for the tier-0 gateway must be active-standby, and the failover mode must be preemptive.

Cloud Management System

- The cloud management system (CMS) must support an NSX-T Data Center plug-in. In this release, VMware Integrated OpenStack (VIO) and vRealize Automation (vRA) satisfy this requirement.

Question 6

An architect is helping an organization with the Logical Design of a Layer 2 bridging solution.

This information was gathered during the Assessment Phase:

Workloads are running on ESXi hosts.

Workloads are running on KVM hosts.

Workloads on hypervisors should use bridging services.

VLAN 50 is used for Tier-0 uplink connectivity.

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

ACreate an NSX Edge Bridge Cluster and configure the bridging profile with VLAN 60.

BCreate an NSX Edge Bridge Cluster and configure the bridging profile with VLAN 50.

CCreate an ESXi Bridge Cluster and configure the bridging profile with VLAN 50.

DCreate an ESXi Bridge Cluster and configure the bridging profile with VLAN 60.
