• Question 11:

  Users run Skype for Business on wireless clients with no WMM support over an Aruba Mobility Master (MM) - Mobility Controller (MC) based network. When traffic arrives at the wired network, it does not include either L2 or L3 markings.

  Which configuration steps should the network administrator take to classify and mark voice and video traffic with UCC heuristics mode?

  A. Enable WMM in a VAP profile, and explicitly permit voice and video UDP ports in a firewall policy.
  B. Confirm OpenFlow is enabled in the user role and VAP profile. Then enable WMM in a SSID profile, and explicitly permit voice and video UDP ports in a firewall policy.
  C. Confirm the MC is the Openflow controller of the MMs and Openflow is enabled in VAP and firewall roles. Enable Skype4Business ALG in UCC profiles.
  D. Confirm MM is the Openflow controller of MCs and Openflow is enabled in VAP and firewall roles. Enable Skype4Business ALG in UCC profiles.
  A. Enable WMM in a VAP profile, and explicitly permit voice and video UDP ports in a firewall policy.

• Question 12:

  Refer to the exhibits.

  

  A user reports slow connectivity to a network administrator when connecting to AP-Garden and suggests that there might be a problem with the WLAN. The user's device supports 802.11n in the 2.4 GHz band. The network administrator finds the user in the Mobility Master (MM) and reviews the output shown in the exhibit.

  What can the network administrator conclude after analyzing the data?

  A. 2.4Ghz band is currently congested, therefore a NIC upgrade to 802.11ac or higher is recommended so the user can move to 5Ghz.
  B. Channel usage is high and though this device has high speed the overall client rate is low on AP-Garden, there could be a few clients monopolizing the airtime on both bands at low speeds.
  C. User's SNR value over time is lower than recommended, therefore he should either get closer to the Access Point or increase the transmit power.
  D. 365s are low cost outdoor APs recommended for coverage design only. AP-Garden currently has more clients than recommended and is getting congested.
  D. 365s are low cost outdoor APs recommended for coverage design only. AP-Garden currently has more clients than recommended and is getting congested.

• Question 13:

  Refer to the exhibit.

  

  Based on the output shown in the exhibit, which wireless connection phase has just completed?

• Question 14:

  Refer to the exhibits.

  

  A network administrator deploys User Based Tunneling (UBT) in a corporate network to unify the security policies enforcement. When users authenticate with 802.1X, ClearPass shows Accept results, and sends the Aruba-User-Role attribute as expected. However, the AOS-CX based switch does not seem to build the tunnel to the Mobility Controller (MC) for this user.

  Why does the switch fail to run UBT for the user?

  A. The switch has not fully associated to the MC.
  B. ClearPass is sending the wrong Vendor ID.
  C. The switch is not configured with the gateway-role.
  D. ClearPass is sending the wrong VSA type.
  E. The switch is not configured with the port-access role.
  B. ClearPass is sending the wrong Vendor ID.

• Question 15:

  An Aruba WiFi solution for a football stadium includes 2500 APs, two Mobility Masters (MM), and eight Mobility Controllers (MCs). Key requirements are seamless roaming and even distribution of APs and clients, even during a MC failure. Which MC's deployment option offers seamless roaming, and even AP client distribution among all MCs before and after a MC failure?

  A. a two-member HA group in dual mode
  B. an eight-member L2-connected cluster
  C. two four-member L2-connected clusters
  D. an eight-member HA group in dual mode
  C. two four-member L2-connected clusters

• Question 16:

  An organization wants to deploy a WLAN infrastructure that provides connectivity to these client categories:

  Employees Contractors Guest users Corporate IoT legacy devices that support no authentication or encryption

  Employees and contractors must authenticate with company credentials and get network access based on AD group membership. Guest users are required to authenticate with captive portal using predefined credentials. Only employees will run L2 encryption.

  Which implementation plan fulfills the requirements while maximizing the channel usage?

  A. Create VAP1 to run WPA2-AES and 802.1x authentication, VAP2 to run opensystem encryption with MAC authentication, and VAP3 to run opensystem with captive portal and L2 fail through.
  B. Create a single VAP to run WPA2-AES and 802.1x authentication, MAC authentication L2 fail through, captive portal, and VIA support.
  C. Create VAP1 to run WPA2-AES and 802.1x authentication, VAP2 to run opensystem encryption with MAC authentication, and VAP3 to run opensystem with captive portal.
  D. Create VAP1 to run WPA2-AES and 802.1x authentication, and VAP2 to run opensystem encryption with MAC authentication and captive portal.
  D. Create VAP1 to run WPA2-AES and 802.1x authentication, and VAP2 to run opensystem encryption with MAC authentication and captive portal.

• Question 17:

  Refer to the exhibit.

  

  A network administrator has a Mobility Master (MM) Mobility Controller (MC) architecture along with the MC in the DMZ for terminating RAPs. The network firewall has been provisioned to allow access to the MC in the DMZ for both UDP 500 and 4500. Then he proceeds to provision an AP as shown in the exhibit.

  Which additional configuration steps must the administrator to assure RAPs successfully contact the MC? (Choose two.)

  A. Create the RAP1 account in the InternalDB of the MC.
  B. Create an IP local pool and PSK at the device node level.
  C. Create the RAP1 account in the InternalDB of the MM.

• Question 19:

  A software development company has 764 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 month, cabling issues have occurred connection to the 7240XM Mobility Controller (MC) that runs ArubaOS 8 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.
