Aruba Certified Mobility Expert (ACMX) HPE6-A48 Updated Questions (61 Q&As)

1. A bank deploys an Aruba Mobility Master (MM)-Mobility Controller (MC) solution to provide wireless access for users that run different applications on their laptops, including SIP-based IP telephony. When users only run the IP telephony software, call quality is high.

However, if users also run email, web, or mission critical applications, then voice quality drops.

Which feature would help improve the quality of voice calls over the air when users run different applications?

2. A point venture between two companies results in a fully functional WLAN Aruba solution. The network administrator uses the following script to integrate the WLAN solution with two radius servers, radius1 and radius2.

While all users authenticate with [email protected] type of credentials, radius1 has user accounts without the domain name portion.

Which additional configuration is required to authenticate corp1.com users with radius1 and corp2 users with radius2?

3. 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?

4. Refer to the exhibits.

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?

6. 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?

7. Refer to the exhibit.

A 7008 Branch Office Controller (BOC) is deployed in a remote office behind a core router. This core router does not support 802.1q encapsulation. The Mobility Controller (MC) is the gateway for two tunneling mode SSIDs, as shown in the exhibit.

Which two different configuration options ensure that wireless users are able to reach the branch network through the router? (Select two.)

8. 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?

9. Confirm that the cluster is L2 connected.

10. Refer to the exhibit.

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?

11. Refer to the exhibit.

A network engineer deploys two different DHCP pools in an Instant AP (IAP) cluster for WLANs that will have connectivity to a remote site using Aruba IPSec.

Based on the output shown in the exhibit, which IAP-VPN DHCP modes are being used?

12. Refer to the exhibits.

Exhibit1

Exhibit 2

Based on outputs shown in the exhibits, what is the reason that AP12 is seen by two different controllers?

13. Refer to the exhibit.

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?

14. 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?

15. 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?

16. 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.)

17. Several users are connected to the same WLAN and want to play the same multicast-based video stream. The network administrator wants to reduce bandwidth consumption and at the same time increase the transmit rate to a fixed value for WMM marked video streams in a large-scale network. Broadcast Multicast Optimization (BCMCO) is already on.

Which two configuration steps does the network administrator have to perform to optimize the multicast transmissions? (Select two.)

18. Refer to the exhibit.

A network administrator wants to allow contractors to access the WLAN named EmployeesNet. In order to restrict network access, the network administrator wants to assign this category of users to the contractor firewall role.

To do this, the network administrator configures ClearPass in a way that it returns the Aruba-User-Role VSA with the contractor value. When testing the solution the network administrator receives the wrong role.

What should the network administrator do to assign the contractor role to contractor users without affecting any other role assignment?

19. 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.)

20. 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?
