An administrator wants to connect four data centers using HP EVI. What is the correct setup for the EVI tunnel interfaces?

• A.Three EVI tunnel interfaces on each EVI edge device-one EVI tunnel interface is required for each GRE tunnel in the mesh
• B.One EVI tunnel interface on Switch 1, which will be configured as the ENDP server, and no interfaces on the other switches
• C.One EVI tunnel interface on each EVI edge device-the devices automatically establish GRE tunnels between these interfaces
• D.Three EVI tunnel interfaces on Switch 1, which will act as the hub. and one EVI tunnel interface each on the other switches

A company has a data center that hosts multiple tenants. The company is adding a second and
third data center switch.
These are the IRF connections:
-IRF 1 is the core of the first data center.
-IRF 2 is the core of the second data center.
-IRF 3 is the core of the third data center
-The three data centers are fully interconnected with dark fiber.
-IRF 1, IRF 2,and IRF 3 have connections to a WAN and to the Internet.
Which option for the connections between the data centers provides the best resiliency and stability?

• A.SPBM configured across IRF 1, IRF 2, and IRF 3
• B.IRF 1, IRF 2, and IRF 3 combined into a single IRF virtual device
• C.MSTP running on the links
• D.A link aggregation that consists of all of the links

A company has two HP Unified Wired-Wireless controllers. The MSM APs in Area 1 in the exhibit are controlled by Controller1. The MSM APs in Area 2 in the exhibit are controlled by Controlled. The company purchases a Controlled to provide backup for both Controller1 and Controller2 (N+1 redundancy).
How does the administrator set up the APs in Area 1 so that they contact Controlled if Controller1 fails?

• A.Create a backup AC configuration group between Controller1 and Controlled. Enable Fast Backup on the group.
• B.Create AP templates for the area 1 APs on Controlled and set its connection priority for these APs to 7.
• C.Create a roam group that includes Controller1, Controlled, and Controlled. Make sure that Controlled has the highest IP address
• D.On Controller1, configure the new controller's IP address as the backup controller for the APs

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.

A large shopping center has an HP BYOD solution with these requirements:
-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 byMAC address. -Each shop has its own SSID.
The administrator wants UAM to display a custom portal page to users based on the SSID to which they connect. What is the proper way to configure this solution?

• A.In the guest access service, bind different SSIDs to different portal pages.
• B.In the access service assigned to the BYODAnonymous account, bind different SSIDs to different portal pages.
• C.In the global guest registration settings, add an SSID map, which binds SSIDs to portal pages.
• D.In the global portal settings, add an SSID map, which binds SSIDs to portal pages.
