Question 1

Refer to Exihbit:

A network administrator is setting up MPLS Layer 2 VPN connections between several customer sites:
Connection 1 = Customer Site 1 to customer Site 2 Connection 2 = Customer Site 1 to customer Site 3
The administrator has established two pseudowires (PW) on PE-1, as shown in the exhibit.
On PE-1, interface GigabitEthemet1/0/1 connects to CE-1 at Site 1. Which setup establishes the desired connections?

A. CE-1 sends traffic to PE-1 G1/0/1 in VLAN 10 and VLAN 20. PE-1 has two services instances on G1/0/1. One instance encapsulates VLAN 10, and PW1 is bound to it. The other instance encapsulates VLAN 20, and PW2 is bound to it.

B. CE-1 assigns VLAN 10 to VPN instance 1 and VLAN 20 to VPN instance 2. PE-1 places G1/0/1 in both VPN instances 1 and 2. PE-1 associates VPN instance 1 with PW1 and VPN instance 2 with PW2.

C. PE-1 has two policy-based routing (PBR) policies, each of which selects traffic destined to Site 2 or Site 3. The appropriate policy is applied to the PW for each connection.

D. CE-1 implements MPLS. It establishes two PWs with PE-1. PE-1 now has four PWs. PE-1 maps the PW3 out label to the PW1 in label. It maps the PW4 out label to the PW2 in label.

Correct Answer: D

Question 2

DRAG DROP
Evaluate each scenario for multi-tenant isolation, and match the scenario to the technology that best meets its needs.

Correct Answer:

Question 3

An SDN application submits a username and password to authenticate to the HP VAN SDN Controller, which is configured for local authentication. If the username and password are valid, what does the controller do?

A. creates a security hash, which the application uses to generate a valid X-Auth-Token

B. forwards the application an Access-Accept packet

C. requests the last valid token the application used

D. sends the application an X-Auth-Token

Correct Answer: D

Question 4

The links marked FCoE link shown in the exhibit are links that need to carry FCoE traffic. What is the proper redundant design for IRF 1?

A. Two VSANs, each of which is bound to FCoE links on both of the physical devices

B. One VSAN, which is bound to FCoE links on both of the physical devices

C. Two VSANs, each of which is bound to the FCoE links on only one of the physical devices

D. Four VSANs, two of which are assigned to FCoE links on one of the physical devices and two of which are bound to links on the other device

Correct Answer: A

Question 5

A company wants to implement an SDN solution that provides a programmable interface for its data center. The company values interoperability, so the solution should not be tied to a particular vendor.
Which technology allows the company to implement an SDN solution that meets these requirements?

A. OpenFlow

B. VXLAN

C. NSX

D. OpFlex

Correct Answer: A

Question 6

Refer to Exhibits:

A network administrator has connected Comware-1 and Comware-2 on their Ten-GigabitEthemet 1/0/2 interfaces. The administrator configured both switches to support FCoE FCF mode and configured the connecting interfaces to carry FCoE traffic. However, the configuration is not working.
The exhibit shows the output for several display commands. Based on this output, which step should the administrator take to fix the problem?

A. Change the port link type on both Ten-GigabitEthemet 1/0/2 interfaces to access.

B. Change the FC mode on the Comware-1 Ten-GigabitEthemet 1/0/2 interface to NP.

C. Change the port link type on both Ten-GigabitEthemet 1/0/2 interfaces to hybrid.

D. Change the FC mode on the Comware-2 Ten-GigabitEthemet 1/0/2 interfaces to E.

Correct Answer: B

Question 7

Refer to Exhibit:

The switches in the exhibit are using SPBM. An administrator wants to send CustomerA traffic directly over the new link, shown by the dotted line in the exhibit, as a premium service for that customer. The existing links will be used for backup. The new link is reserved for CustomerA traffic.
How does the administrator set up Switch 1 to help to achieve this goal?

A. by creating a PW connection between Switch 1 and Switch 3, and mapping the CustomerA service instance to that PW

B. by setting up a new B-VLAN and assigning it to the new link and the backup links, and mapping the CustomerA l-SID to that B-VLAN

C. by changing the CustomerA l-SID 255 and defining the interface for the reserved link as the priority path inl-SID 255

D. by assigning the CustomerA interfaces and the specific links in the path to the same S-
VLAN ID

Correct Answer: B

Question 8

Refer to Exhibit:

The switches shown in the exhibit use the HP VAN SDN Controller as the OpenFlow controller. They connect to the controller on their out-of-band management (OOBM) ports, but these connections are not shown in the exhibit. The switches also run spanning tree protocol.
An SDN supplication installed on the HP VAN SDN Controller is programmed to discover live ports, find redundant paths, and create loopfree paths for traffic for the infrastructure shown in the exhibit. However, the application is not able to complete these functions because the switches are reporting some ports as blocked.
What should the network administrator do to let the application create the loopfree paths?

A. Disable spanning tree on the OpenFlow-enabledswitches and do not configure link aggregation.

B. Disable spanning tree on the OpenFlow-enabled switches and configure the redundant links as static link aggregations-

C. Enable spanning tree on the OpenFlow-enabled switches and configure all of the redundant links as egress-only-ports.

D. Enable spanning tree on the OpenFlow-enabled switches but set the application as the spanning tree flood parameter controller.

Correct Answer: B

Question 9

What is a benefit of using the HP Network Visualizer SDN application for capturing traffic on HP Provision switches?

A. This application can configure mirroring on switches that do not support OpenFlow using traditional methods, eliminating the needs for upgrades.

B. This application can integrate with VMware vCenter, which uses the captured traffic to determine the correct policies to deploy to virtual hosts.

C. This application can forward the captured traffic to HP DVLabs for deeper inspection as to whether the traffic poses a threat to the network.

D. This application can correlate captured traffic with user information based on information synced with Microsoft Active Directory.
