HP HP0-Y51 Exam Questions & Answers

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. 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.

A company has an HP Unified Wired-Wireless controller that controls HP MultiService Mobility (MSM) APs. The network administrator wants to implement protection against rogue APs in the company's campus environment. Only APs that have approved MAC addresses should be allowed to operate and support clients. Controlled APs should send disassociation frames to prevent clients from connecting to rogue APs.

The administrator sets up APs to monitor the area and creates a permitted MAC address list with the approved AP MAC addresses. The administrator has not configured any other Intrusion Detection System (IDS) settings. Which additional step must the administrator complete?

A. Enable a dynamic blacklist.

B. Configure the permitted vendor and permitted SSID lists.

C. Enable countermeasures.

D. Deploy the permitted MAC address list as a static attack list to each controlled AP

An HP Unified Wired-Wireless controller controls an AP. The AP implements centralized forwarding. It supports 802.11n clients that implement Wi-Fi Multimedia (WMM) or 802.11 e. Some of the clients are sending traffic in high priority WMM queues.

How does the AP help to ensure that this traffic is prioritized in the wired LAN?

A. It maps 802.11 values from wireless traffic to DiffServ Code Points (DSCP) in packets tunneled to the controller.

B. It implements 802.11n fair scheduling on the port that connects to the switch.

C. It maps 802.1p values from wireless traffic to 802.11 e values in packets forwarded into the LAN.

D. It implements Spectralink and uses Spectralink-to-WMM compliance mode.
