Answer

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

Answer

Meet with the organization’s application team to get additional information.

Answer

Monitor East-West traffic throughout normal business cycles.

Question 5

Accepted Answer

Network I/O Control Profiles

Answer

LLDP Profile

Answer

LAG Uplink Profile

Answer

Transport Node Profiles

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:Customer currently has a single 10 host vSphere cluster.

Customer wants to improve network security and automation.

Current cluster utilization and business policies prevent changing the existing vSphere deployment.

High-availability is important to the customer.

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

Accepted Answer

Apply vSphere DRS VM-Host anti-affinity rules to the virtual machines of the NSX-T Edge cluster.

Accepted Answer

Deploy the NSX Controllers in the management cluster.

Accepted Answer

Remove 2 hosts from the cluster and create a new edge cluster.

Answer

Deploy at least two NSX-T Edge virtual machines in the vSphere cluster.

Answer

Apply vSphere Distributed Resource Scheduler (vSphere DRS) VM-Host anti-affinity rules to NSX Managers.

Answer

Remove vSphere DRS VM-Host affinity rules to the NSX-T Controller VMs.

Question 7

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.)

Accepted Answer

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

Answer

There are applications which use IPv6 addressing.

Answer

Hosts can only be configured with two physical NICs.

Answer

There are enough CPU and memory resources in the existing management cluster.

Question 8

Which two benefits can be achieved using in-band management of an NSX Bare Metal EdgeNode? (Choose two.)

Accepted Answer

Reduces cost.

Accepted Answer

Reduces egress data.

Answer

Reduces storage requirements.

Answer

Preserves packet locality.

Answer

Preserves switchports.
