An organization owns a fully functional multi-controller Aruba network with a Virtual Mobility Master (VMM) in VLAN 20. They have asked a network consultant to deploy a redundant MM on a different server. The solution must offer the lowest convergence time and require no human interaction in case of failure. The servers host other virtual machines and are connected to different switches that implement ACLs to protect them. The organization grants the network consultant access to the servers only, and appoints a network administrator to assist with the deployment. What must the network administrator do so the network consultant can successfully deploy the solution? (Select three.)

A) Reserve one IP address for the second MM and another IP address for its gateway
B) Configure an ACL entry that permits IP protocol 50, UDP port 500, and multicast IP 224.0.0.18.
C) Allocate VLAN 20 to the second server, and extend it throughout the switches.
D) Reserve one IP address for the second MM and another for the VIP.
E) Configure an ACL entry that permits UDP 500, UDP 4500, and multicast IP 224.0.0.1.
F) Allocate another VLAN to the second server, and permit routing between them.

A foreign exchange broker in a shared office space uses an Aruba Mobility Master (MM) -Mobility Controller (MC) architecture along with ClearPass and AirWave. The corporate network is FXBroker121, but users report that they cannot access the FXBroker111 SSID. The team suspects that a rogue AP is in place and a malicious user tried to disguise the WLAN name. How can the organization's network administrator identify and locate the potential rogue AP?

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?

Refer to the exhibits. Exhibit 1 Exhibit 2 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?

Refer to exhibit. A company has a multiple Arua implementation with three different locations named Headquarter, Branch, and Telecommuters. The network design includes the following: Headquarter APs terminate at the Mobility Controller (MC) cluster and propagate Corporate, Guest, and Voice SSIDs Branch APs terminate at the Branch Office Controller (BOC) and propagate Corporate and Voice SSIDs BOC reaches the Mobility Master (MM) through a VPNC. Telecommuter RAPs terminate at VPNC and propagate Corporate and Voice SSIDs. The Corporate SSID on the RAPs is split-tunnel, all other SSIDs are tunnel. The network design requires minimal AP group and VAP configuration effor, while preventing unnecessary VAP propagation to lower hierarchy levels. Following Aruba node hierarchy desing recommendations, which group hierarchy design helps meet these requirements?

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?

Refer to the exhibits. Exhibit 1 Exhibit 2 A network administrator adds a new Mobility Controller (MC) to the production Mobility Master (MM) and deploys APs that start broadcasting the employees SSID in the West wing of the building. Suddenly, the employed report client disconnects. When accessing the MM the network administrator notices that the MC is unreachable, then proceeds to access the MC's console and obtains the outputs shown in the exhibits. What should the network administrator do next to solve the current problem?

A financial institution contacts an Aruba partner to deploy an advanced and secure Mobility Master (MM) -Mobility Controller (MC) WLAN solution in its main campus and 14 small offices/home offices (SOHOs) . Key requirements are that users at all locations, including telecommuters with VIA, should be assigned roles with policies that filter undesired traffic. Also, advanced WIPs should be enforced at the campus only. These are additional requirements for this deployment: RAPs should ship directly to their final destinations without any pre-setup and should come up with the right configuration as soon as they get Internet access. Activate should be configured with devices MACs, serial numbers, and provisioning rules that redirect them to the standalone VMC at the DMZ Users should be able to reach DNS, FTP, Web and telephone servers in the campus as well as send and receive IP telephone calls to and from the voice 10.1.50.0/24 segment. Local Internet access should be granted. Refer to the exhibit. Refer to the scenario and the exhibit. The standalone VMC will act as a VPN Concentrator of the RAPs. The network administrator configures the Standalone VMC with a pool of addresses and the SOHOs AP Group from the MM. Which additional steps must the network administrator perform to allow the RAPs to terminate their IPSec tunnels and associate to the Standalone VMC?

Refer to the exhibits. Exhibit 1 Exhibit 2 Exhibit 3 A network administrator deploys a Mobility Master (MM) pair with the VRRP VIP equal to 10.254.10.214, and attempts to associate MC1 to it. At first, the integration appears to be successful. However after a few minutes the network administrator issues the show switches command and sees that the MC1 is down, even though the device is up and running. Every time the network administrator reboots the Mobility Controller (MC) , the MC shows as being up and then it shows as being down. The network administrator gathers the information shown in the exhibits. What should the network administrator do to resolve this problem?

Refer to the exhibit. A network administrator deploys a Mobility Master (MM) -Mobility Controller (MC) solution in the headquarters. The network administrator prepares the wired side of the network with the proper VLAN, DHCP settings, and routing services to ensure that APs can reach the MCs. The network administrator connects two APs in different IP segments and waits for 20 minutes, but SSIDs are advertised in one of the APs only. The engineer logs into the MC console and sees the output shown in the exhibit. What is the reason that the AP20 is not broadcasting SSIDs?

A network administrator assists with the migration of a WLAN from a third-party vendor to Aruba in different locations throughout the country. In order to manage the solution from a central point, the network administrator decides to deploy redundant Mobility Masters (MMs) in a datacenter that are reachable through the Internet. Since not all locations own public IP addresses, the security team is not able to configure strict firewall policies at the datacenter without disrupting some MM to Mobility Controller (MC) communications. They are also concerned about exposing the MMs to unauthorized inbound connection attempts. What should the network administrator do to ensure the solution is functional and secure?

Company 1 and Company 2 are medium-sized companies that collaborate in a joint venture. Each company owns a building, and each has their own ArubaOS 8 Mobility Master (MM) -Mobility Controller (MC) deployment. The buildings are located in front of one another. For the initial stage of the project, the companies want to interconnect their networks with fiber, and broadcast each other's SSIDs. These are the requirements: Do not unify the company's network management responsibilities. Allow each company to take care of their own SSID setups when broadcasted in the other building. Terminate Company 1 user traffic on Company 1 MCs when they connect to Company 2 APs. Terminate Company 2 user traffic on Company 2 MCs when they connect to Company 1 APs. What is needed to meet the solution requirements?

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?

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 network administrator deploys APs with radios in Air Monitor mode and detects several APs and SSIDs that belong to stores next door. The Mobility Master (MM) classifies the APs and SSIDs as potential rogues. The network administrator wants to prevent the Air Monitor from applying countermeasures against these APs. How can the network administrator accomplish this?

Refer to the exhibit. A network administrator configures a Mobility Master (MM) -Mobility Controller (MC) solution and integrates it with AirWave. The network administrator configures the SNMP and terminal credentials in the MM and MC, and then monitors the mobility devices from AirWave, including Clarity for user association and basic network services verification. However, AirWave does not display any UCC data that is available in the MM dashboard. Based on the information shown in the exhibit, which configuration step should the network administrator do next in the MM to complete the integration with AirWave?

A company has headquarters based in the US and rents internation office space in Mexico City so that 10 employees can work remotely. The company must implement a remote access technology so branch office employees can access all servers at the headquareters.
