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. Configure controller 1 as a backup controller for APs in area; configure controller 2 as a backup controller for APs in area1.

C. Change the security mode to preshared key (PSK) and enable opportunistic key change (also called "fast roaming").

D. Set up enable a roam that includes both controllers.

What correctly describes the role of OpenFlow in an SDN solution?

A. OpenFlow regulates the communications among teamed SDN controllers, as well as between an SDN controller and a network infrastructure device

B. OpenFlow integrates the SDN controller into a larger management suite such as that provided in an HP CloudSystern solution.

C. OpenFlow is a communication protocol that an SDN controller can use to control devices at the network infrastructure layer.

D. OpenFlow is the open standard technology that regulates SDN control plane and application plane communications.

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:

A Contractor 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

A company has an HP BYOD solution to let guests connect to a Guest SSID and log in through a registration page. The company needs an Employee SSID which enforces Wi-Fi Protected Access 2 (WPA2) with 802.1X. Employees must authenticate with certificates. Before authenticating with a device for the first time, the employees should be able to connect to the Guest SSID, access the guest registration page, and download valid certificates.

How does the administrator configure User Access Manager (UAM) to allow employees to download certificates from the registration page?

A. The User Endpoint Settings, create an Endpoint Configuration Distribution Policy that permits the employee groups.

B. In the Guest Manager settings for the employee manager, enable auto-registration in certificate mode.

C. In the Guest access policy, make sure that a policy binds the Employee SSID to an access rule with the onboarding VLAN ID.

D. In the Employee access service, make sure that a policy binds the Employee SSID to an access rule with the onboarding VLAN ID.

A company has three HP VAN SDN Controllers, which will be deployed in a team. The administrator is deciding whether to create one region or three regions. What is a benefit of creating three regions rather than one region?

A. The team can load balance the team leader role, increasing the total number of RESTful API and Java API calls that the solution can handle.

B. The team can provide high availability for SDN application functions rather than only for the OpenFlow controller functions rather than only for the OpenFlow controller functions.

C. The team can load balance the Master OpenFlow controller role, increasing the total number of packetin messages per second that the solution can handle.

D. The team can provide high availability for all the OpenFlow controller functions rather than only for the SDN application functions.

The exhibit shows the Fibre Channel (FQ zones that are members of zonesets on an HP Comware switch. How does this zoning affect the FC fabric operation?

A. Host bus adapter (HBA) pWWNs in zoneset 1 belong to VSAN 1, which is currently active. HBA pWWNs in zoneset 2 belong to VSAN 2, which is inactive

B. Server pWvVNs in zone 1 can discover targets pWWNs in zone 2. Server pWWNs in zone 3 can discover target pWWNs in zone 4.

C. A sender pWWN in zone 1 can discover target pWWNs in zone 1. A server pWWN in zone 2 can discover target pWWNs in zone 2.

D. The switch matches a host bus adapter (HBA) pWWN to entries in zone 1 to determine whether an HBA can connect to a port. If it does not find a match, it checks zone 2.

An HP Virtual Cloud Networking (VCN) SDN Application runs on an HP VAN SDN Controller. How does VCN help to provision networking for virtualized services in a cloud solution?

A. By using northbound RESTful APIs to receive information from servers and switches acting as Network Functions Virtualization (NFV)-complaint routers

B. By using northbound Java APIs to integrate with and configure Ethernet Virtual Bridging (EVB) applications

C. By using southbound OpenStack Layer 2 Agent APIs to set up the correct VLANs on virtual switches, as well as tunnels between virtual switches

D. By using southbound RADIUS APIs to provision dynamic VLANs on data center switches, basing those VLANs on the customer identity

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.

How does the administrator set up the APs in Area 1 so that they contact Controlled if Controller1 fails?

A. Create a roam group that includes Controller1, Controlled, and Controlled. Make sure that Controlled has the highest IP address

B. Create AP templates for the area 1 APs on Controlled and set its connection priority for these APs to 7.

An administrator has set up an HP BYOD solution for an HP MSM760 controller and its APs.

These are the specifications:

Guests should only have to register and log in once After that, the guest device should be automatically logged in.

User Access Manager (UAM) provides the portal in which guests register their own accounts.

The MSM760 is connected to a Comware switch, which redirects unregistered guests to the UAM portal.

Currently guests can reach the portal, register for their accounts, and log in. However, guests report that they cannot reach the Internet after they log in. When the administrator asks the guests to disconnect from the wireless network and then connect again, they succeed in reaching the Internet.

What could fix this problem?

A. In the Comware switch settings, add the guest router to the free rule list

B. In the DHCP scope for the onboardmg VLAN, lower the lease time to about 10 seconds.

C. Configure SOAP settings for the MSM controller on UAM.

D. Configure the Comware switch to accept dynamic authorization updates from UAM.

B. Dynamic frequency selection (DFS)

C. Transmit power control (TPC)

D. Fair scheduling
