• Question 25:

  A foreign exchange broker in a shared office space uses an Aruba Mobility Master (MM)-Mobility Controller (MC) architecture along with ClearPass and AirWave. The corporate network is FXBroker121, but users report that they cannot access the FXBroker111 SSID. The team suspects that a rogue AP is in place and a malicious user tried to disguise the WLAN name.

  How can the organization's network administrator identify and locate the potential rogue AP?

  A. Create an AirWave RAPIDS rule with a Suspected Rogue classification and the SSID Matches FXBroker111 condition, then access any RAPID List entry that matches the rule and click on Location.
  B. Use ClearPass Event viewer and search for entries with the FXBroker111 Aruba-Essid-Name VSA attribute, then obtain the value of the Aruba-AP-Group attribute.
  C. Use ClearPass Event viewer and search for entries with the FXBroker111 Aruba-Essid-Name VSA attribute, then obtain the value of the Aruba-Location-id attribute.
  D. Create and AirWave RAPIDS rule with a Suspected Rogue classification and the SSID Does Not Match FXBroker121 condition, then access any RAPIDS List entry that matches the rule and click on Location.
  B. Use ClearPass Event viewer and search for entries with the FXBroker111 Aruba-Essid-Name VSA attribute, then obtain the value of the Aruba-AP-Group attribute.

• Question 26:

  A network administrator deploys APs with radios in Air Monitor mode and detects several APs and SSIDs that belong to stores next door. The Mobility Master (MM) classifies the APs and SSIDs as potential rogues. The network administrator wants to prevent the Air Monitor from applying countermeasures against these APs.

  How can the network administrator accomplish this?

  A. Select the BSSID and click reclassify, then select neighbor.
  B. Run the Define WIP Policy task, and define the BSSIDs of the neighboring APs as interfering.
  C. Select the BSSID and click reclassify, then select interfering.
  D. Run the Define WIP Policy task, and define the BSSIDs of the neighboring APs as Authorized.
  A. Select the BSSID and click reclassify, then select neighbor.

• Question 27:

  A software development company has 700 employees who work from home. The company also has small offices located in different cities throughout the world. During working hours, they use RAPs to connect to a datacenter to upload software code as well as interact with databases.

  In the past two months, brief failures have occurred in the 7240XM Mobility Controller (MC) that runs ArubaOS 8.3 and terminates the RAPs. These RAPs disconnect, affecting the users connected to the RAPs. This also causes problems with code uploads and database synchronizations. Therefore, the company decides to add a second 7240XM controller for redundancy.

  How should the network administrator deploy both controllers in order to provide redundancy while preventing failover events from disconnecting users?

  A. Connect both controllers with common VLANs, and create an L2-connected cluster using public addresses in the internet VLAN.
  B. Connect both controllers with common VLANs, and create an HA fast failover group with public addresses in the internet VLAN.
  C. Connect both controllers with different VLANs, and create an L2-connected cluster using private addresses in the internet VLAN.
  D. Connect both controllers with common VLANs, and configure LMS/BLMS values equal to public addresses in the internet VLAN.
  A. Connect both controllers with common VLANs, and create an L2-connected cluster using public addresses in the internet VLAN.

• Question 28:

  Refer to the exhibit.

  

  A user's laptop only operates in the 2.4 GHz band and supports 802.11n. This user reports that the network is slow at the cafeteria that is serviced by three APs, and suggests that there might be a problem with the WLAN. The network administrator finds the user in the MM, and obrains the output shown in the exhibit.

  What should the network administrator do to optimize the client connection?

• Question 29:

  Users run encrypted Skype for Business traffic with no WMM support over an Aruba Mobility Master (MM)-Mobility Controller (MC) based network. When voice, video, and application sharing traffic arrive at the wired side of the network, all the flows look alike due the lack of L2 or L3 markings.

  How can the network administrator identify these flows and mark QoS accordingly?

  A. Confirm the MC is the Openflow controller of the MMs and Openflow is enabled in VAP and the firewall roles. Then enable WMM in a VAP profile.
  B. Confirm the MM is the Openflow controller of the MCs and Openflow is enabled in VAP and the firewall roles. Then integrate the MM with the Skype4Business SDN API, and enable the Skype4Business ALG in the UCC Profiles.
  C. Confirm the MC is the OpenFlow controller of the MMs and Openflow is enabled in VAP and the firewall roles. Then enable the Skype4Business ALG in the UCC profiles.
  D. Use a media firewall policy that match these three flows, and use permit and TOS actions with 56, 40, and 34 values for voice, video, and application sharing, respectively. Then enable the Skype4Business ALG in the UCC profiles.

• Question 30:

  A financial institution contacts an Aruba partner to deploy an advanced and secure Mobility Master (MM)-Mobility Controller (MC) WLAN solution in its main campus and 14 small offices/home offices (SOHOs). Key requirements are that users

  at all locations, including telecommuters with VIA, should be assigned roles with policies that filter undesired traffic. Also, advanced WIPs should be enforced at the campus only.

  These are additional requirements for this deployment:

  RAPs should ship directly to their final destinations without any pre-setup and should come up with the right configuration as soon as they get Internet access.

  Activate should be configured with devices MACs, serial numbers, and provisioning rules that redirect them to the standalone VMC at the DMZ

  Users should be able to reach DNS, FTP, Web and telephone servers in the campus as well as send and receive IP telephone calls to and from the voice 10.1.50.0/24 segment.

  Local Internet access should be granted.

  Refer to the exhibit.
