Building HP SDN and FlexNetwork Solutions: HP0-Y51

A company has HP MultiService Mobility (MSM) APs that receive DHCP addresses on several different subnets. The APs are controlled by an MSM Controller. The company is considering replacing the MSM Controller with a Unified Wired-Wireless controller. The administrator runs a proof of concept test in which some of these APs are discovered and controlled by the Unified Wired-Wireless controller. Now the administrator wants to return the APs to being controlled by the MSM Controller.

The network administrator performs these actions:

Ensures that the Colubris vendor-specific option in each AP subnet DHCP scope references the MSM Controller IP address

Reboots the APs.

The MSM Controller never succeeds in discovering the APs. A debug reveals that the APs are not contacting the controller at all.

Which action could fix this problem?

A. Reset the APs to the factory default settings

B. In each AP DHCP scope, delete the Colubris vendor-specific option

C. Add a DNS host entry that maps hp example com to 10.1.10.20.

D. Upload MSM software to the HP Wired-Wireless controller flash.

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 can be obtained by sending a calf with valid credentials https.Controller_IP.8443/sdn/v2.0/ auth

B. 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.

C. 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.

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.

A company has a Unified Wired-Wireless controller solution, which uses its local portal to authenticate guests.

The company is adding an HP BYOD solution with these requirements:

The User Access Manager (UAM) server with IP address 10.1 3.4 should provide the portal in which guests register own accounts

Guests should only have to register and log in once. After that, the guest device automatically logs in by MAC address

The administrator removes the local portal settings and begins to reconfigure the solution. What is one change that the administrator must take to the settings for the Guest SSID?

A. Apply an ACL that redirects HTTP traffic to 10.1.3.4.

B. Configure the associated WLAN-ESS interface as a hybrid port and enable MAC-based VLANs.

C. Create a domain that specifies 10.1.3.4 as the RADIUS server and define that as the portal domain.

D. Set up a remote portal server that specifies the UAM IP address and portal URL.
