Question #1

Refer to the exhibit.

A network administrator has recently enabled WMM on the VAP’s SSID profile and enabled UCC Skype4B ALG at the Mobility Master level. During testing, some voice and video conference calls were made, and it was concluded that the call quality has dramatically improved. However, end to end information isn’t displayed in the call’s details. Also, Skype4B app-sharing’s performance is poor at times.

What must the administrator do next in order to enable end to end call visibility and QoS correction to app-sharing service?

  • A . Deploy the SDN API Software in the Skype4B Solution and point to the MM.
  • B . Increase the app-sharing DSCP value in the Skype4B ALG profile.
  • C . Enable UCC monitoring on the "default-controller’ mgmt.-server profile.
  • D . Enable the App-sharing ALG profile at both MM and MD hierarchy levels.

Question #2

A company with 535 users deploys an Aruba solution with more than 1000 Aruba APs, two 7220 Mobility Controllers, and a single Mobility Master (MM) virtual appliance at the campus server farm. The MCs run a HA Fast failover group in dual mode and operate at 50% AP capacity.

If there is an MM or MC failure, the network administrator must ensure that the network is fully manageable and the MC load does not exceed 80%.

A network administrator wants to allow contractors to access the corporate WLAN named EmployeesNet with the contractor role in VLAN 40. When users connect, they do not seem to get an IP address. After some verification checks, the network administrator confirms the DHCP server (10.254.1.21) is reachable from the Mobility Controller (MC) and obtains the outputs shown in the exhibits.

What should the network administrator do next to troubleshoot this problem?

  • A . Permit UDP67 to the contractor role.

Question #5

Refer to the exhibit.

A network administrator adds a Mobility Controller (MC) in the /mm level and notices that the device does not show up in the managed networks hierarchy. The network administrator accesses the CLI. executes the show switches command, and obtains the output shown in the exhibit.

What is the reason that the MC does not appear as a managed device in the hierarchy?

  • A . The network administrator added the device using the wrong Pre-Shared Key (PSK).
  • B . The network administrator has not moved the device into a group yet.
  • C . The digital certificate of the MC is not trusted by the MM.
  • D . The IP address of the MC does not match the one that was defined in the MM.

Question #6

Refer to the exhibit.

A network administrator deploys a Mobility Master (MM) – Mobility Controller (MC) network with Aps in different locations. Users in one of the locations report that the WiFi network works fine for several hours, and then they are suddenly disconnected. This symptom may happen at any time, up to three times every day, and lasts no more than two minutes.

After some research, the network administrator logs into the MM and reviews the output shown in the exhibit.

Based on this information, what is the most likely reason users get disconnected?

  • A . Adaptive Radio Management is reacting to RF events.
  • B . AirMatch is applying a scheduled optimization solution.
  • C . Users in the 2.4 GHz band are being affected by high interference.
  • D . AirMatch is reacting to non-scheduled RF events.

Question #8

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.

Question #9

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 to the lack of L2 and 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 . 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.
  • 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 . 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.
