Aruba Study Guide: ACMX 6.X
The ACMX 6.X exam tests
many aspects common
to most customer deploy-
ments, as well as elements
considered of significance
for larger enterprise
environments. These
include topics such as:
• Familiarity with AOS
6.0.1.3
• IP planning, subnetting,
VLAN assignment, and
implementation
• License capacity planning
• Master redundancy
• Local redundancy
(AP termination)
• IP Mobility
• Adaptive Radio
Management
• Spectrum Monitoring
• Policy and role design
and implementation
• Authentication
• Campus Mesh
• Voice support
• Remote AP Operations
and Configuration
• AirWave (7.2)
• Additional best practices
as detailed in VRDs
• Troubleshooting
• Syslog configuration

Recommended Preparation
The exam draws upon material found in various Aruba course
material and Validated Reference Designs (VRDs). The recommended
courses include Introduction to Aruba WLANs (IAW), Scalable WLAN
Design and Implementation (SWDI), Advanced Troubleshooting (ATS),
and AirWave training course. The VRDs represent the best practices
for designing and deploying Aruba networks, and are available for
download at http://arubanetworks.com/technology/design guides.
php. Familiarity with the Aruba user and cli guides is highly suggested.
Additionally, we recommend at least one year of hands on experience
with Aruba products in actual customer deployments.
Note that you are not expected to provision any third party components.
Your responsibility is to successfully deploy the Aruba system to
support the features in your exam. For example, this may involve the
usage of third party elements such as Voice Phones. But you will not
be required to provision the phones.
Tested Areas
IP Design
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.
Ensure you understand the difference and know how to provision the
controller for both L2 and L3 switching.
License Capacity Planning
The lab consists of several controllers with different purposes. Ensure
that you know appropriate usage of licenses and plan your implemen-
tation appropriately.
Redundancy
Both master and local redundancy may be present in the exam. There
are very specific requirements to enable these features if they are
requested in your exam scenario. Ensure that you understand how
these operations behave and how to correctly provision them. Failure
to correctly implement redundancy may have a significant negative
impact on your exam score. Knowledge of VRRP, lms and backup lms
usage and provisioning is highly recommended.
Your responsibility is
to successfully
deploy the
Aruba system to
support the features
in your exam.

4
Policies and Roles
The exam attempts to emulate a corporate enterprise setting. This
extends into the exam security requirements. Proper construction of
policies and roles is required in the exam. Be sure to read your scenario
requirements carefully so you do not lose points through incorrect
role behavior.
Authentication
The Aruba controller supports many forms of authentication and can
query servers such as Radius, LDAP and an internal database. You
must be able to provision the controller to interact with any of these
servers, and to troubleshoot any issues that may be present.
Campus Mesh
Mesh elements assist in extending a network into areas where wired
connectivity may be limited or non-
existent. Mesh consists of a mesh
portal and a mesh point, which together form connections into these
difficult areas. Your exam may require you to build a mesh solution to
solve such a problem.
Voice
Many enterprise environments depend more and more upon VoWiFi
solutions for communications within an enterprise facility. Unique
Aruba solutions provide a high quality voice experience when correctly
implemented. Be sure you know what options are available to provide
this service and how to provision them.
Remote Networking
With an increasing need for workers to access corporate resources
from remote locations, a need arises for secure connectivity that
leverages wireless availability regardless of the geographical location.
Zero touch provisioning simplifies an administrator’s logistics for
deploying remote access points. Familiarity with provisioning all elements
of Aruba remote networking products is highly recommended.
AirWave
We use AirWave version 7.2 in the exam. You are expected to be
able to provision the Aruba network to be seen and monitored by the
AirWave server.
Knowledge of
redundancy
options, firewall
policies and roles,
mobility and
troubleshooting
are highly
recommended.

5
Best Practices
Provisioning ARM appropriately for the given scenario is expected.
Also, setting up connectivity to a syslog server for troubleshooting.
These common elements are expected to be present in the solution
and have points associated with them. The elements are covered in
the courses mentioned above (IAW/SWDI/ATS) as well as in the VRDs.
Troubleshooting
Events may arise in the exam demanding a candidate to troubleshoot.
In-
depth knowledge of how a normally functioning Aruba system
should operate is recommended.
Additionally, fluency using debug as well as an awareness of cli “show”
commands for diagnosing an Aruba system is essential to ensure that
all requested features successfully operate by the end of the exam.
The troubleshooting course (ATS) and extensive experience with Aruba
in real-
world deployments will provide the knowledge and skill needed
for the test. The VRDs also provide much troubleshooting information.
Scoring
Scoring follows the philosophy that “Just because something works,
that doesn’t mean it is working correctly.” Points are awarded for both
a functioning feature and for a correct configuration.
Scoring involves extensive testing of the features. That means that
if a feature appears to be working, points are awarded. But the
feature must work in all possible expected scenarios, especially
regarding redundancy.
Additionally, the proctor examines the configuration for completeness.
Therefore, a candidate can receive partial credit for an incomplete
activity.
But the candidate is not very likely to pass the exam by having a
working feature built with incomplete configurations that do not meet
all of the requirements. Nor is it possible to pass the exam with
dysfunctional features even if most of a configuration is complete.
Both working features and acceptable configurations are required to
score enough points to pass the 75% pass threshold.
Scoring starts with zero points. A successfully completed task adds
points. Test areas are weighted with redundancy, role development
and mobility activities having the most significance.
