問題1

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. Set up enable a roam that includes both controllers.

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

正確答案: D

問題2

A company has an HP BYOD solution. The administrator is setting up synchronization of user accounts from Active Directory (AD). The administrator wants User Access Manager (UAM) to organize the user accounts in groups in the same way that AD does.
How does the administrator configure this to accomplish the goal?

A. Install the UAM agent on the AD server, otherwise, UAM can only synchronize the highest-level group of domain users.

B. Create every group before setting up the LDAP synchronization policy

C. Establish the LDAP synchronization policy, and then create a user group policy to synchronize the groups and sort the user accounts

D. In the LDAP Server policy, set the User Group setting to Synchronize by OU, which allows AD to create the groups automatically

正確答案: D

問題3

Table of Acronyms

Refer to the exhibit.

An administrator is configuring an MPLS and VPLS Martini to connect customer Sites 1, 2, and 3. The administrator has created Virtual Switch Instance (VSI) "CustomerA" for this purpose.
How should the administrator connect customer Site 1 to the VPLS solution?

A. Create a service instance on the VLAN assigned to g1/0/1. Also create a global cross-connect group, and bind the CustomerA VSI and the service instance in that group.

B. Create a service instance on g1/0/1. Also create a global cross-connect group, and bind the CustomerA VSI and the service instance in that group.

C. Create a service instance on the VLAN assigned to g1/0/1. Bind (cross-connect) that instance to the CustomerA VSI.

D. Create a service instance on g1/0/1. Bind (cross-connect) that instance to the CustomerA VSI.

正確答案: B

問題4

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

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

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

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

正確答案: C

問題5

Table of Acronyms What is a benefit of enabling tandem multicast replication for SPBM?

A. Multicasts follow a better path to each destination than they would with head-end replication.

B. SPBM switches can send multicasts as both multicasts and unicasts, increasing reliability for the transmission.

C. An ingress SPBM switch can load-balance multicasts over multiple equal-cost paths to a destination, even when the multicast belong to the same I-SI

D. An ingress SPBM switch does not have the load of replicating and forwarding many copies of a multicast.

正確答案: A

問題6

Refer to the exhibit.

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

B. On Controller1, configure the new controller's IP address as the backup controller for the APs

C. Create a backup AC configuration group between Controller1 and Controlled. Enable Fast Backup on the group.

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