• Question 32:

  Refer to the exhibit.

  

  A network administrator deploys a multizone AP in the campus network in order to provide service for 11 SSIDs.

  B. Increase the number of nodes in zones 1 and 4, and confirm MC1 and MC4 are reachable by AP12.

  C. Confirm that AP12 is certified by the whitelist on MC1 and MC4, and increase the number of nodes in zones 1 and 4.

  Correct Answer: D

• Question 33:

  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, ang then they are suddenly disconnected. The 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, the network administrator logs into the MM and reviews the output shown in the exhibit.

  Correct Answer: B

• Question 34:

  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.

  Correct Answer: D

  Exhibit 3

  

  A network engineer deploys a Master Controller (MC) cluster at Headquarter to offer high levels of redundancy, and prepares the wired side of the network. This preparation includes the VLAN, DHCP Settings, and unicast routing services that APs require to reach the cluster.

  The network engineer waits for 20 minutes after connecting the APs and sees that no SSIDs are advertised. The network engineer logs into one of the MCs and one of the AP's consoles to obtain the outputs shown in the exhibits.

  What can the network engineer do to fix the APs discovery process, to ensure the best scalability even if one MC fails?

  A. Reprovision the APs with a different Master IP.

  B. Modify the IP address in one of the MCs.

  C. Modify option 43 in the DHCP pool.

  D. Create a VRRP instance in the MCs.

  Correct Answer: C

• Question 37:

  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.

  B. 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.

  C. Create a single VAP to run WPA2-AES and 802.1x authentication, MAC authentication L2 fail through, captive portal, and VIA support.

  D. Create VAP1 to run WPA2-AES and 802.1x authentication, and VAP2 to run opensystem encryption with MAC authentication and captive portal.

  Correct Answer: A

• Question 38:

  Refer to the exhibit.

  

  A network administrator is in charge of a wired and wireless Aruba network where access control is needed for both connection methods. For the wired solution, the network administrator wants the users authentication to be performed at the switches, while tunneling their traffic to MC1 whenever possible for firewall policy enforcement. The network administrator configures and tests ClearPass as the RADIUS server in the switches.

  Which switch configuration scripts should the network administrator use next to achieve this goal?

• Question 39:

  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.

  Correct Answer: A
