NO.22 An administrator wants to add a new folder in AirWave. Where would the administrator perform this action?

NO.23 An administrator needs to modify a VAP used for a branch office RAP. The VAP’s operating mode is currently defined as backup and uses tunnel mode forwarding. The administrator wants to implement split-tunnel forwarding mode in the VAP.
Which WLAN operating mode must the administrator define for the VAP before the tunnel forwarding mode can be changed tosplit-tunnel?

NO.24 A customer uses an SIP application that is not supported by Aruba United Communications and Collaboration (UCC). Which voice deployment mode should the administrator implement on Aruba Mobility Controllers (MCs) to support this application?

NO.25 An administrator wants to use AirWave to manage the configuration policysettings of a set of ArubaOS-Switches. Where should the administrator perform this action?

NO.26 An administrator supports a network that contains ArubaOS-Switches and Mobility Controllers (MCs).
Restrictive MC firewall policies, control wireless access. The administrator wants to implement a feature to apply the same MC firewall policies to users connected to the Ethernet switch ports.
Which ArubaOS-Switch feature provides this capability?

NO.27 An AP connects to a controller. Then, the AP loses power and reboots.
Which parameters will the AP remember and use from its initial connection? (Select two.)

NO.28 An administrator wants to reduce downtime of the wireless network when controllers are upgraded. Which Aruba OS feature should the administrator implement to reduce theamount of downtime the Aps will experience at the time of the upgrade process?

NO.29 An administrator implements blacklisting of users that fail authentication functions three or more times.By default, how long will these users have to wait before they can successfully log into the network again?

NO.30 An administrator implements two redundant Aruba Mobility Masters (MMs). Which protocol should the administrator use to detect a failure in a single subnet?

NO.31 A branch office location has two buildings: an office and a small warehouse that are within 20 meters of each other. A RAP at the branch office provides connectivity to the corporate office network. This RAP is also configured as a Remote Mesh Portal (RMP).
Which solution should the administrator implement to provide connectivity between the office and small warehouse buildings at the branch office location?

NO.32 Refer to theexhibit.

An administrator configures a policy for an AP Group. Port 3 of a RAP is a trunk that connects to a switch at a branch office. VLAN 1 is untagged and VLANs 10 (for data) and 11 (for voice) are tagged. The administrator applies an ACL inbound on Port 3 of the RAP.
How does this configuration affect traffic on Port 3?

NO.33 Refer to the exhibit.

What can an administrator determine from this Aruba device output?

NO.34 An administrator configures an ArubaOS-Switch for per-user tunneled node. Which protocols does the switch use to establish and maintain a connection with the Aruba Mobility Controller (MC)? (Choose two.)

NO.35 An administrator mistakenly configures the wrong VLAN setting on a managed controller’s interface. This causes the controller to lose management access to the Mobility Master (MM). The administrator knows that the auto roll-back feature will revert the managed controller to a previous configuration that was used prior to the change.
Which command can the administrator use to validate that the rollback process is successful?

NO.36 An administrator at Campus A manages Aruba Mobility Controllers (MCs). The administrator defines a server group that includes a local ClearPass server and a remote Microsoft RADIUS server. The ClearPass server has the credentials for users at Campus A and the Microsoft RADIUS server has the credentials for users at Campus В. Users at Campus A successfully authenticate and connect to the Campus A wireless network.
However, when users from Campus В visit Campus A they fail authentication.
What can the administrator do to solve this problem?

NO.37 Which methods can be used to configure RAP redundancy when connected to two redundant Aruba Mobility Controllers (MCs) in the DMZ? (Select two.)

NO.38 An administrator troubleshoots a roaming problem where a user loses connectivity to the network during the roaming process. To help troubleshooting this problem, which device or devices in a wireless network initiates the roaming process?

NO.39 Refer to the exhibit.

Which controller shown in the exhibit is elected as the cluster leader?

NO.40 An administrator wants to dynamically upgrade AppRF on Aruba Mobility Controllers (MC) in a cluster. The administrator does not want to reboot the system at the time of the upgrade.
What should the administrator use for this upgrade?

NO.41 Refer to the exhibit.

Which controller connection with the Aruba as the cluster leader?

NO.42 An administrator configures two Mobility Masters (MMs) for redundancy and databasesynchronization.
Which protocol transports database information between the two MMs?

NO.43 Refer to theexhibit.

An administrator configures a split-tunnel policy to be used by RAPs at branch offices. Under the Configuration section on the Mobility master (MM) shown in the exhibit, where should the administrator configure the split-tunnel mode sothat it can be deployed to the RAPs?

NO.44 Refer to the exhibit.

An administrator supports a RAP at a branch office shown in the exhibit. The company has one Mobility Controller (MC) at the Primary DMZ site and one at the Secondary DMZ site. TheRAP is configured to connect to only the MC at the Primary DMZ site. A network outage with the ISP at the Primary DMZ site causes the RAP to reboot. Upon reboot, the RAP cannot build a tunnel to the Secondary DMZ site MC because the administrator forgot toadd the Second LMS IP address to the AP Group configuration. Once the RAP can successfully connect, the administrator can add the Secondary DMZ MC as a backup LMS to fix the AP Group.
What should the administrator implement to allow the RAP to connect tothe MC at the Secondary DMZ site while the outage at the primary site persists?
