The HPE6-A48 ACMX Written Exam is required to be passed before the practical exam. Once the written is passed, you will only have 18 months to pass the ACMX Practical Exam. Candidates who do not pass the ACMX 8 Practical Exam within 18 months will have to retake the current ACMX Written Exam. HPE recommends that you register for the ACMX Practical Exam within 12 months of passing the written exam to ensure that you pass in the allotted 18-month timeframe.

Exam description
This exam tests your ability to design and configure an enterprise Aruba WLAN deployment using AOS 8.3 and aspects common to enterprise customer deployments. Candidates prove their ability to design solutions that include AirWave, L2/L3 infrastructure, WLANs (including MultiZone) and Guest provisioning, design networks around colorless ports and experience with voice applications including knowledge of optimization of UCC, video and multicast in Aruba environments.

Ideal candidate for this exam
Ideal candidates for this exam are networking IT professionals with a minimum of three to five years’ experience in designing and integrating complex enterprise-level mobile first networks. Candidates should have familiarity with integrating Aruba Mobility Controllers (MM, MC, and VMC), Access Point (CAP, UAP, RAP, and IAP), AirWave, and wired network using ArubaOS switches (3810 & 2930F) products for secure employee access, guest, UCC, QoS, and multicast deployments.

Objectives
This exam validates that you can:
Percentage of Exam Sections/Objectives

27% L2/L3 Infrastructure
The most significant step towards successfully completing the exam is to ensure that the controller infrastructure is deployed correctly. This includes the VLAN and IP addressing aspects. If these are not completed correctly, it is impossible to pass the exam as the balance of the exam depends upon a correct IP infrastructure. For this exam you will need to understand the difference between these aspects, and know how to deploy the controllers in both L2 and L3 models.

The lab consists of several Mobility Controllers (MMs, MCs, and VMCs) with different purposes. You will need to know the correct usage of licenses and plan your implementation appropriately. The lab may also require licensing deployment. Mobility Master and MC/VMC redundancy may be present in the exam. There are specific requirements to enable these features if you exam scenario requires them. You will be required to understand how these operations behave and how to correctly provision them. Failure to correctly implement redundancy may have a significant impact on your exam score. This exam requires knowledge and implementation of AP mobility controller discovery, L2/L3 MM redundancy, L2/L3 clustering, HA, VRRP, LMS/backup LMS, and troubleshooting enterprise networks.

42% WLAN Service
This exam requires candidates to be familiar with all WLAN authentication types, and MultiZone in order to meet exam scenario requirements. You will also be required to understand planning and implementing of Guest provisioning using an internal or external captive portal and how to deploy a Spectrum Analyser and Air Monitor.

As companies grow, their need for workers to access corporate resources from remote locations increases. This results in a need for secure connectivity that leverages availability regardless of geographical location. Aruba highly recommends that you have a familiarity with provisioning all elements of Aruba’s remote networking products before taking this exam. The exam requires proper construction of policies and roles.

Please read your scenario requirements carefully so you do not lose points through incorrect role behavior. Aruba recommends that you know what options are available to provide this service and how to provision them before taking this exam

9% Wired Service (Dynamic Segmentation)
Candidates must demonstrate working knowledge of design wired networks around colorless ports and understand implementation of tunneled-node (per user tunneled node or per port tunneled node).

13% Advanced Features
This exam attempts to emulate a corporate enterprise setting. This extends into the exam security requirements. Provisioning AirMatch, ARM, and radio profiles appropriately for the given scenario is expected. HPE Aruba official courses cover these elements as well the VRDs.

Many enterprise environments depend more and more upon VoWiFi/UCC solutions for communications within an enterprise facility. Unique Aruba solutions provide a high quality voice experience when correctly implemented. Aruba expects candidates to have working knowledge of optimization of UCC, video, and multicast in Aruba environments. Aruba recommends that you know what options are available to provide this service and how to provision them before taking this exam.

9% Network Management
You will use AirWave in the exam. You are expected to be able to provision the Aruba network to ensure an AirWave server can see and monitor the network. The candidate must be ready to demonstrate working knowledge of VisualRF, auditing, reporting and RAPIDS.

QUESTION: 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?

A. DSCP for IPv4 traffic
B. WiFi Multi Media
C. Type of Service
D. High/Low Queue

Answer: A

QUESTION: 2
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?

A. 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.

B. 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.

C. 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.
D. 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.

Answer: D


QUESTION: 3
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
