QUESTION 21

Which two characteristics of the underlying physical network does VMware NSX require for robust IP transport? (Choose two.)

 

A.

The physical network should provide scalable network I/O using Layer 2 Multipathing (L2MP) and Multichassis Link Aggregation (MLAG).

B.

The physical network should provide scalable network I/O using Equal Cost Multipathing (ECMP).

C.

QoS is not necessary since classification and marking will be done in the overlay.

D.

QoS classification and marking is required to provide end-to-end flow control.

QUESTION 23

The Exhibit shows two possible physical network architectures. Each architecture provides a means in dealing with the pictured failure.

 

Based on the exhibit, which architecture provides the highest degree of connectivity in the event of the pictured failure?

 

clip_image002

 

A.

Both designs will provide the same percentage of connectivty in times of failure.

B.

Neither design is properly architected to work around the displayed failure.

C.

Diagram A’s architecture will provide the highest percentage of connectivity in times of failure.

D.

Diagram B’s architecture will provide the highest percentage of connectivity in times of failure.

QUESTION 24

An NSX administrator has deployed the network shown in the Exhibit.

 

Based on the exhibit, which statement describes a valid method for redirecting traffic around the fault?

 

clip_image004

 

A.

Building this topology using a layer 2 switched fabric with connectivity between the leafs would allow traffic to be redirected around the fault to another leaf.

B.

Building this topology using a layer 3 routed fabric with connectivity between the leafs would allow traffic to be redirected around the fault to another leaf.

C.

Building this topology using a layer 2 switched fabric with spanning tree will provide the quickest path around the fault to another spine when connectivity is lost.

D.

Building this topology using a layer 3 routed fabric will provide the quickest path around the fault to another spine when connectivity is lost.

 

Correct Answer: D

 

 

QUESTION 25

QUESTION 26

Which Virtual Machine cannot be protected by the Distributed Firewall?

 

A.

A Virtual Machine connected to a vDS Portgroup running on an ESXi 5.1 host.

B.

A Virtual Machine connected to a vSS Portgroup running on an ESXi 5.5 host.

C.

A Virtual Machine connected to a vDS Portgroup running on an ESXi 5.5 host.

D.

A Virtual Machine connected to a logical switch running on an ESXi 5.1 host.

 

Correct Answer: D

QUESTION 27

Your data center clusters are configured as shown in the exhibit.

 

Core0 uses Virtual SAN and hosts virtual machines running the following components:

 

clip_image006vCenter Server

clip_image006[1]Single Sign-On Server

clip_image006[2]Update Manager

clip_image006[3]SQL Server database

 

Core1, Core2, and Core3 use a single Fibre Channel attached storage array. Core1 hosts over 500 virtual machines. Core2 hosts over 400 virtual machines. Core3 hosts 100 virtual machines.

 

Following VMware’s best practices, NSX Controller components should be deployed to which location(s)?

 

clip_image008

 

A.

Deploy three NSX Controllers, one on each host of Core0.

B.

Deploy four NSX controllers, one on each cluster in the data center.

C.

Deploy 27 NSX controllers, one for each host in the data center

D.

Deploy three NSX controllers. Deploy one in Core1, one in Core2, and one in Core3.

 

Correct Answer: A

 

 

QUESTION 28

Which statement is true regarding deploying NSX over a physical network?

 

A.

OSPF can be used for Management traffic in a Layer 3 fabric design.

B.

NSX can implement IPv6 on an IPv4 physical network.

C.

Routing is supported on bridged interfaces.

D.

VLANs are not required to separate traffic between virtual machines.

 

Correct Answer: B

 

QUESTION 29

How does NSX simplify physical network design?

 

A.

VLANs are moved into the virtual network for virtual machine traffic, eliminating the need to use Private VLANs on the physical network.

B.

Network administrators only need to configure routing on the physical network for virtual machine traffic since all other network functions are moved to the virtual network.

C.

Transport zones are created in the virtual network for virtual machine traffic, removing the need to make changes to the physical network.

D.

Virtual network integration can make changes to the physical network programmatically using REST API calls which automates network changes and increases agility.

 

Correct Answer: C

 

 

QUESTION 30

A company hosts an internal website on multiple virtual machines attached to a Logical Switch with VNI 7321. A Distributed Router serves as the virtual machines’ default gateway. When a user resolves the URL for the website, the internal DNS server responds with the IP address of one of the virtual machine’s IP addresses in a round robin fashion. This approach results in some virtual machines having a much higher number of user sessions than others. The company wants to deploy a NSX Edge Service Load Balancer to improve on this situation. Which distribution method can be configured on the NSX Edge Load Balancer to meet the company’s needs?

 

A.

LEAST_CONN

B.

IP_HASH

C.

LEAST_LOAD

D.

URI
