E Preserves switchports.

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:
✑ NSX-T will span across two sites for disaster recovery.
✑ Public Load Balancer VIP should be accessible from a secondary site.

✑ NAT capabilities are required.
Which two selections should the architect include in their design? (Choose two.)

A Use of the same ISPs across sites.
B Use two separate ISPs across sites.
C Use MTU to 1550 between sites.
D Set MTU to 1550 between sites.
E Use IP sets or groups to configure DFW rules.

Question 7

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 Ã— 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.)

A Load Balance Source MAC
B Load Balance Port ID
C Load Balance Source
D Load Balance Source Port ID
E Failover Order

Question 8

Which two resources can be used by an NSX architect during the Assessment Phase? (Choose two.)

A vRealize Network Insight
B VMware Validated Design
C VMware customer references
D key stakeholder interviews
E application licensing

Question 9

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

A Use a load balancer.
B Use round-robin DNS.
C Use NAT.
D Use a cluster Virtual IP.

Question 10

What would an architect recommend to a customer that wants to extend management to an additional data center through Layer 2, but does not want to add additional NSX-T licensing? (Choose the best answer.)

A Deploy a standalone NSX Controller.
B Deploy a standalone NSX Manager.
C Deploy a standalone Edge as the IPSec VPN.
D Deploy Autonomous Edge as the L2 VPN client.

Question 11

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.)

A Create a Tier-0 gateway in Active/Standby mode and a Tier-1 gateway in Active/Standby mode.
B Configure ECMP and Load Balancing on the Tier-0 gateway.
C Create a Tier-0 gateway in Active/Active mode and a Tier-1 gateway in Active/Standby mode.
D Create a Tier-0 gateway in Active/Standby mode.

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 Enagagement 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 constraint was documented by the architect? (Choose the best answer.)

A Dynamic routing should be configured between the physical and virtual network.
B There are applications which use IPv6 addressing.
C Hosts can only be configured with two physical NICs.
D There are enough CPU and memory resources in the existing management cluster.

An architect is helping an organization with the Physical Design of an NSX-T Data Center solution.
This information was gathered during a workshop:
✑ There are six hosts and hardware has already been purchased.
✑ Customer is planning a collapsed Management/Edge/Compute cluster.
