    auth-server radius1 match-domain corp1.com
    auth-server radius1 match-domain corp2.com
Correct answer: B
Question 2
A network administrator implements a SIP-based IP telephone solution. The objective is to ensure that APs use 100% of their airtime for network access whenever a voice call is taking place, to minimize communication delays. The network administrator also wants to ensure that a log entry is generated when voice calls occur. 
Which setup accomplishes these tasks? 
  1. ip access-list session voice
    user any svc-rtsp permit log queue high
    user any svc-sip-udp permit log queue high
  2. ip access-list session voice
    user any-svc-rtsp permit disable-scanning log
    user any svc-sip-udp permit disable-scanning log
  3. ip access-list session voice
    user any svc-rtsp permit log dot1p-priority 7
    user any svc-sip-udp permit log dot1p-priority 7
  4. ip access-list session voice
    user any svc-rtsp permit log tos 56
    user any svc-sip-udp permit log tos 56
Correct answer: C
Question 3
Refer to the exhibit. 
  
A user reports show response time to a network administrator and suggests that there might be a problem with the WLAN. The user’s laptop supports 802.11n in the 2.4 GHz band only. The network administrator finds the user on the Mobility Master (MM) and reviews the output shown in the exhibit. 
What can the network administrator conclude after analyzing the data?
  1. Client health is low, and retried frames are high. It is possible there is high channel utilization.
  2. Client health is low, but SNR is high. It is possible data in the dashboard is not accurate and needs to be updated.
  3. The speed is good. Client health seems to be related to a problem with the client NIC.
  4. The network is low because of low SNR. TX power must be increased in both the client and the AP.
Correct answer: B
Question 4
A customer with a multi-controller network upgrades the ArubaOS from 6.4 to 8. The customer’s clients must be able to move between different locations of the campus without disconnecting their applications, when roaming or if there are Mobility Controller (MC) failures. The customer also wants to have full control of the users, and be able to change their session properties from a RADIUS server. 
Which steps must the network consultant include in the implementation plan to meet these requirements?
  1. 1. Create a controller cluster profile that contains the management and VRRP IP addresses of each member. 
    2. Apply the profile to all MCs in the cluster. 
    3. Confirm that the cluster is L2 connected.
  2. 1. Configure a VRRP instance for all MCs 
    2. Create a controller cluster profile that contains the management IP and VIP addresses of each MC. 
    3. Apply the profile to all MCs in the cluster. 
    4. Confirm that the cluster is L2 connected.
  3. 1. Configure a VRRP instance for each MC. 
    2. Create a controller cluster profile that contains the management IP of each member. 
    3. Apply the profile to all MCs in the cluster. 
    4. Confirm that the cluster is L3 connected.
  4. 1. Create a controller cluster profile that contains the management and VRRP IP addresses of each member. 
    2. Apply the profile to the cluster leader. 
    3. Confirm that the cluster is L2 connected.
Correct answer: D
Question 5

  1. distributed L3 and centralized L3
  2. distributed L3 and local L3
  3. distributed L3 and centralized L2
  4. local L3 and centralized L2
Correct answer: C
Question 6
A network administrator deploys AirWave over a Mobility Master (MM)-Mobility Controller (MC) network to monitor, audit, and report activities. The main areas of concern are with high user density, not enough APs, or not enough channel bandwidth. 
Which two report options can the network administrator user to create a weekly report that shows networking equipment with more users and high-demand applications used by top talkers? (Select two.)
  1. Most Utilized Folders by Maximum Concurrent Clients
  2. Most Utilized by Usage
  3. Top Applications Summary
  4. Most Utilized by Maximum Concurrent Clients
  5. Top 3 Applications For Top 10 Users
Correct answer: BD
Question 7
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? 
  1. tunneled-node-server
    controller-ip 10.19.10.100
    backup-controller-ip 10.20.10.100
    mode role-based
    aaa authentication port-access eap-radius
    aaa port-access authenticator 1-22
    aaa port-access authenticator active
  2. tunneled-node-server
    controller-ip 10.20.10.100
    backup-controller-ip 10.19.10.100
    mode port-based
    aaa authentication port-access eap-radius
    aaa port-access authenticator 1-22
    aaa port-access authenticator active
  3. tunneled-node-server
    controller-ip 10.20.10.100

    aaa authentication port-access eap-radius
    aaa port-access authenticator 1-22
    aaa port-access authenticator active
Correct answer: C
Question 8
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?
  1. 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.
  2. 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.
  3. Create a single VAP to run WPA2-AES and 802.1x authentication, MAC authentication L2 fail through, captive portal, and VIA support.
  4. 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 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 the lack of L2 or L3 markings. 
How can the network administrator identify these flows and mark QoS accordingly?
  1. 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.
  2. 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.
  3. 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.
  4. 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
Question 10
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. 
Based on this information, what is the most likely reason users get disconnected?
  1. AirMatch is applying a scheduled optimization solution.
  2. Users in the 2.4 GHz band are being affected by high interference.
  3. Adpative Radio Management is reacting to RF events.
  4. AirMatch is reacting to non-scheduled RF events.
