The Aruba Certified Mobility Professional (ACMP) is a professional-tier wireless certification from HPE Aruba (transitioning to the ACP — Campus Access track). It validates advanced ArubaOS 8.x/10.x design and troubleshooting: Mobility Conductor configuration hierarchy, MC cluster architecture (hitless failover, live upgrade, fast-failover, bucket maps), AirMatch global RF planning, ClientMatch steering, AirSlice SLAs, MPSK Local/Cloud, mesh, EAP-TLS with OCSP, RADIUS CoA, downloadable user roles, captive portal advanced design, WIDS rogue classification and containment, and Aruba Central NetConductor (VXLAN-EVPN).

1In an ArubaOS 8.x deployment, what is the primary role of the Mobility Conductor (MM)?

A.Terminate AP GRE tunnels and forward client data

B.Centralize configuration management and license distribution for managed Mobility Controllers

C.Run ARM and AirMatch on each AP independently

D.Provide DHCP services to wireless clients

Explanation: The Mobility Conductor (formerly Master Controller) is the configuration brain of an ArubaOS 8.x deployment. It hosts the configuration hierarchy, pushes profiles to managed Mobility Controllers (MCs), and distributes licenses. The MM does not terminate AP tunnels — that is the role of the MC.

2Two Mobility Conductors are deployed in 1+1 redundancy. Which database synchronization method keeps their configurations identical?

A.VRRP heartbeat

B.DBsync over the L2-connected VRRP VLAN

C.RADIUS accounting

D.CPsec certificate exchange

Explanation: In an MM 1+1 redundancy pair, the active and standby Mobility Conductors run a VRRP instance and use DBsync to replicate the configuration database. DBsync runs over the IP interface protected by VRRP, ensuring the standby has an identical CPDB at all times.

3In the ArubaOS 8.x configuration hierarchy, where should you place a setting that must apply to every managed device?

A.At the /md node only

B.At the /mm node

C.At the device-specific node

D.Inside the User role profile

Explanation: The configuration hierarchy is rooted at /mm (Mobility Conductor management) and /md (managed devices). Settings under /md are inherited by every managed controller and AP. /mm settings apply only to the MM itself. Place global client-affecting settings at /md.

4Which statement about an ArubaOS 8.x Mobility Controller cluster is correct?

A.All cluster members must be in different L2 subnets

B.Cluster members share AP and client load and provide hitless client failover

C.Only one cluster member can serve APs at a time

D.Clusters require ClearPass to function

Explanation: An MC cluster (up to 12 nodes) provides AP load balancing, client load balancing, hitless client failover (Standby UAC concept), and live upgrades. Clients are distributed across cluster members using a hash, and a Standby UAC pre-installs client state so failover is seamless.

5What does the AAC (Active User Anchor Controller) do in an ArubaOS 8 cluster?

A.Encrypts AP traffic with CPsec

B.Holds the live client session and forwards user data

C.Acts as the standby for AP tunnels only

D.Manages the AirMatch RF plan

Explanation: In a cluster, each client is assigned an Active UAC (the controller actively serving its session) and a Standby UAC (which holds a synced copy of session state). If the Active UAC fails, the Standby UAC instantly takes over without requiring re-authentication.

6During an ArubaOS 8 live upgrade of a cluster, what allows clients to remain connected?

A.APs reboot one at a time and bridge traffic locally

B.Each cluster member is upgraded sequentially while clients are temporarily moved to other members

C.All controllers reboot at once for shortest outage

D.CPsec certificates are reissued mid-upgrade

Explanation: Live upgrade walks through cluster members sequentially. Before a node is upgraded, its APs and clients are migrated to other healthy cluster members. After reboot, the node rejoins and load is rebalanced. The result is no client outage during the upgrade.

7Which feature allows a client to fail over from one cluster member to another in under one second without re-authentication?

A.802.11r Fast BSS Transition

B.Hitless client failover via Standby UAC

C.Mesh fast convergence

D.ARM scanning

Explanation: Hitless client failover is delivered by the cluster's Standby UAC: the standby holds a pre-installed copy of the client's session state, encryption keys, and role assignment. When the active fails, the standby takes over in milliseconds with no 802.1X re-auth.

8You are designing a cluster for two data centers connected by an L3 link. Which cluster type is appropriate?

A.L2-connected cluster

B.L3-connected cluster

C.Master-local with no cluster

D.VRRP-only redundancy

Explanation: When cluster members are separated by an L3 boundary, configure an L3-connected cluster. L3 clusters support load balancing and failover but do not support all hitless features that require shared L2 (such as a cluster VRRP IP for client gateway). Choose L2 within a site whenever possible.

9What is the maximum number of Mobility Controllers supported in a single ArubaOS 8.x cluster?

A.4

B.8

C.12

D.32

Explanation: ArubaOS 8.x supports up to 12 Mobility Controllers in a single cluster. All members must run the same code train and share the same AP load and license pool through the Mobility Conductor.

10What does the ClusterManager service in ArubaOS 8 do?

A.Provides DHCP scopes for clients

B.Coordinates cluster membership, leader election, AP and client load balancing across members

C.Manages firmware downloads from HPE

D.Performs rogue AP containment

Explanation: ClusterManager is the control-plane process that handles cluster membership, leader election, distribution of AP load and client load, and rebalancing during failover or live upgrade. It uses heartbeats over the cluster control channel to detect node health.

Aruba ACMP Study Tips from Top Performers

1Build a 2-node MC cluster in a lab and trigger a live upgrade — observe bucket map changes with `show ap bucketmap`

2Memorize the configuration hierarchy: /mm scope (MM only) vs /md scope (cascades to managed devices)

3Know AirMatch vs ARM: AirMatch is centralized on the MM with 24-hour data; ARM is local per AP

4Practice 802.1X with EAP-TLS, OCSP revocation checks, and downloadable user roles via ClearPass

5Study CoA flows (Disconnect-Request, CoA-Request) and how ClearPass changes a session role mid-flight

6Be fluent in show commands: show ap database, show ap arm rf-summary, show airmatch, show wms client, show crypto isakmp sa

Frequently Asked Questions

What is the Aruba ACMP exam format?

ACMP (legacy code HPE6-A71) has approximately 60 multiple-choice and scenario questions in 90 minutes at Pearson VUE. Passing is approximately 65%. The exam is being rebranded under the HPE Aruba Networking Certified Professional — Campus Access track but tests the same advanced wireless mobility content.

Do I need ACMA before taking ACMP?

ACMA is recommended but not strictly required. HPE expects candidates to know ArubaOS basics, WLAN design, and ClearPass at an associate level before tackling ACMP's advanced cluster, AirMatch, and security topics.

Is ACMP being retired?

HPE is transitioning the wireless track to the HPE Aruba Networking Certified Professional — Campus Access (HPE7-A01) credential, which combines wired and wireless professional content. ACMP-aligned content (ArubaOS 8.x clusters, AirMatch, ClientMatch, MPSK) remains highly relevant for Campus Access.

What is the hardest ACMP topic for most candidates?

MC cluster behavior — bucket maps, AAC/SAC roles, fast-failover sequencing, and live upgrade ordering — trips up most candidates because it requires hands-on lab time. RF planning (AirMatch vs ARM, AirSlice) is a close second.

How long should I study for ACMP?

Plan 80–120 hours over 8–12 weeks if you already hold ACMA. Focus on hands-on cluster configuration, AirMatch behavior, ClearPass integration with downloadable user roles, and CLI troubleshooting (show ap arm rf-summary, show airmatch, show ap bucketmap).
