When should an administrator enable hybrid mode on an HP VAN SDN Controller?

• A.When the controller must manage Mininet switches in a developer environment and HP switches in a production environment
• B.When the controller must manage HP Provision switches that operate in passive mode
• C.When the controller must manage OpenFlow-enabled switches that support both OpenFlow 1.0 and 1.3
• D.When the controller must manage HP Provision switches that use virtualization mode to enable OpenFlow on some VLANs but not on others

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

An HP VAN SDN Controller runs the HP Network Protector SDN Application. The application has programmed an HP Switch with flows that output to the service insertion tunnel. How does the switch forward packets matching these flows to the controller?

• A.Encapsulated in OpenFlow packets and transmitted over the auxiliary connection
• B.Encapsulated in a GRE tunnel
• C.Encapsulated in an IPSec tunnel
• D.Encapsulated in OpenFlow packets and transmitted in the controller VLAN

An administrator is customizing an HP BYOD self-registration page. The administrator does not want guests to see the identity number field. Instead the User Access Manager (UAM) server should automatically choose a valid identity number for a guest account when the guest registers.
What are the correct settings for the identity number field in the customized page? (Select three)

• A.Random
• B.Not required
• C.Visible
• D.Invisible
• E.Fixed
• F.Required

Refer to the exhibit.

A company has HP APs that are managed by the two Unified Wired-Wireless controllers. Wireless
users use Wi-Fi Protected access (WPA2) and authenticate with 802.1X to HP Access Manager (UAM). The SSID uses centralized forwarding. Users need to be able to roam seamlessly from area 1 to area 2.
Which step helps to meet these needs?

• A.Configure local forwarding for the SSID on both controllers.
• B.Set up enable a roam that includes both controllers.
• C.Configure controller 1 as a backup controller for APs in area; configure controller 2 as a backup controller for APs in area1.
• D.Change the security mode to preshared key (PSK) and enable opportunistic key change (also called "fast roaming").
