HP Building HP SDN and FlexNetwork Solutions Sample Questions:

1. An SDN application needs to create reactive flow table entries in response to specific packets. The flow_mod APIs will create the actual entries, but application must be configured with another API as part of this function.
What is that API?

A) A sequence packet listener (SPL) API that specifies the Advisor role and the match criteria for the packets
B) A listener API that registers the application to listen for data paths
C) A sequence packet listener (SPL) API that specifies the Director role and the match criteria for the packets
D) A listener API that registers the application to listen for meters

2. A company is adding an HP BYOD solution. User Access Manager (UAM) should provide the portal in which guests register their own accounts. Guests should only have to register and log in once. After that, the guest device automatically logs in by MAC address.
UAM has these settings:
-User account BYODAnonymous = Assigned to Access service 1 -Guest access service = Access service 2 -Access service 1: Default access policy = Access policy 1 -Access policy 1: No certificate authentication and User VLAN 8 -Access service 2. Default access policy = Access policy 2 -Access policy 2: No certificate authentication and User VLAN 88
How should the administrator configure portal authentication (HTTP redirection)?

A) Set up portal authentication to UAM in the Unified Wired-Wireless controller VLAN 88 settings
B) Set up portal authentication on the default gateway for VLAN 88.
C) Set up portal authentication to UAM in the Unified Wired-Wireless controller Guest SSID settings.
D) Set up portal authentication to UAM on the default gateway for VLAN 8.

3. A company has an external SDN application that works with an HP VAN SDN Controller. The application programmer has tried testing several RESTful API calls but receives authentication errors. What does the administrator need to explain to the programmer?

A) Every RESTful API call must include an X-Auth token. The token must be created by a valid certification authority (CA) and installed on both the controller and external application in advance.
B) Every RESTful API call must include an X-Auth token. The token can be obtained by sending a calf with valid credentials https.Controller_IP.8443/sdn/v2.0/auth
C) Every RESTful API call must include a valid username and password. The only exception is when the AuthRequired parameter is set to false in restful conf file.
D) The application must be installed with a certificate that is signed by the same certification authority (CA) that signed the VAN SDN Controller certificate.

4. A company has an Employees SSID, which enforces Wi-Fi Protected Access 2 (WPA2) with 802.1X. The company has a Contractors SSID, which has no encryption. Contractors can connect their own devices to the Contractors SSID and log in the credentials assigned to them by an employee. HP User Access Manager (UAM) has these services:
-AContractor access service, which is assigned to contractor accounts created by employees -An Employee access service, which is assigned to employee accounts synchronized from Active
Directory (AD)
A new company policy encourages contractors to use encryption. Contractors should download certificates when they connect to Contractors SSID and register. Then the contractors can connect to the Employees SSID and have an encrypted connection.
How does the administrator enable the contractors to connect to the Employees SSID but receive the correct contractor VLAN assignment?

A) In the Employee access service, bind the Contractor group to an access policy that specifies the contractor VLAN ID and PAP authentication.
B) In the Employee access service, bind the Contractor group to an access policy that specifies the contractor VLAN ID and EAP-TLS certificate authentication
C) In the Contractor access service, bind the Employees SSID to an access policy that specifies the contractor VLAN ID and EAP-TLS certificate authentication
D) In the Contractor access service, bind the Employees SSID to an access policy that specifies the contractor VLAN ID and PAP authentication

5. An administrator plans to deploy a wireless network, which might need to support a mix of 802.11g and 802.11n clients in the 2.4 GHz frequency. The administrator wants to prioritize transmissions for 802.11 n clients. Which 2.4 GHz radio setting helps to prevent slow clients from taking more than their share of transmission time?

A) Set the mandatory data rate for 802.11g as low as possible.
B) Set the multicast data rate for 802.11n as low as possible.
C) Set up the channel reuse option.
D) Set up the fair scheduling option.
