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 digital certificate of the MC is not trusted by the MM.
C. The IP address of the MC does not match the one that was defined in the MM.
D. The network administrator has not moved the device into a group yet.

A network administrator deploys DSCP based prioritization in the entire wired network to improve voice quality for a SIP-based IP telephony system used by the company. However, users report that calls they make from the WLAN have poor audio quality, while desktop phones do not experience the same problem. The network administrator makes a test call and looks in the datapath session table.
Based on the output shown in the exhibit, what is one area that the network administrator should focus on?
A. wireless network congestion
B. WMM support on the WLAN
C. UCC based DSCP correction
D. wired network congestion

After a recent power outage where MM1 is located, the network administrator could not perform configuration tasks on Mobility Controllers (MC) for several hours. The network administrator decides to acquire another Mobility Master (MM) and deploy L2 MM redundancy. The new MM is assigned the
10.254.10.15 IP address and VRRP is configured in both units. The network administrator verifies that VRRP is running, and prepares to complete the setup with the following scripts.
Which configuration tasks must the network administrator do before applying the script in order to successfully deploy L2 MM redundancy and prevent any other control plane outage?
A. Confirm that the VRRP and master redundancy keys are the same.
B. Change the VIP address of ther VRRP process 140 to 10.254.10.15.
C. Reduce the VRRP priority to 90 and restart the process in MM2.
D. Enable the MM database synchronization in MM2.
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.

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

A network administrator deploys a test environment with two Mobility Masters (MMs), two two-member Mobility Controller (MC) clusters, and two CAPs, with the intention of testing several ArubaOS features, Cluster members run VRRP for AP boot redundancy. Based on the information shown in the exhibits, what is the current status of the APs?
A. APs are currently communicating with LMS IP, and 10.1.140.100 is S-AAC.
B. APs are currently communicating with BLMS IP, and 10.1.140.101 is A-AAC.
C. APs are currently communicating with BLMS IP, and 10.1.140.101 is S-AAC.
D. APs are currently communicating with BLMS IP, and 10.1.140.100 is A-AAC.

A network administrator must ensure that a ClearPass server can receive the RADIUS authentication request from a single Mobility Controller (MC) managed by a Mobility Master (MM). Based on the exhibits, what is the value of NAS-IP contained in the RADIUS access requests?
A. 10.1.140.98
B. 10.1.140.99
C. 10.1.140.100

An airline wants to invest in an Aruba Mobility (MM)-Mobility Controller (MC) solution for the three hubs it has throughout the country. A single MM is located in the datacenter at one of the hubs. The MCs in the other two hubs reach the MM through a site-to-site IPSec VPN.
The operations team does not want to lose monitoring and configuration control of the MCs if something happens to the datacenter where the MM resides.
Which solution ensures that there is management access to the MCs in case of an MM failure due to a datacenter outage?
A. Deploy another MM in a different location, and enable L2 redundancy.
B. Install AirWave Management Platform, and enable Read and Write Management access on devices.
C. Deploy another MM in a different location, and enable L3 redundancy.
D. Deploy a local MM on each hub, and synchronize the configuration between all MMs.
A network administrator needs to deploy L2 Mobility Master (MM) redundancy. MM1 uses IP address
10.201.0.10 and MAC address 1c:98:ec:25:48:50, and MM2 uses IP address 10.201.0.20 and MAC 1c:98:ec:99:8a:80. Both run VRRP process with VRID 201.
Which configuration should the network administrator use to accomplish this task?
A. /mm (MM1): database synchronize period 30 /mm/mynode (MM1): master-redundancy master-vrrp 201 peer-ip-address 10.201.0.20 ipsec key123 /mm/mynode (MM2): master-redundancy master-vrrp 201 peer-ip-address 10.201.0.10 ipsec key123
