- HPE's certification catalog currently lists Aruba Certified Mobility Expert (ACMX) as inactive, so there is no live passing score to prepare against.
- The written-exam reference tied to this credential family is HPE6-A79, a legacy datacard rather than an open registration target.
- Historical Aruba expert-level exams used scaled scoring, not a simple raw-percentage cutoff, delivered through Pearson VUE.
- The general OnVUE at-home availability statement explicitly excludes Aruba Expert exams, so it cannot be used to infer ACMX availability.
Why "Passing Score" Is a Trick Question for ACMX Right Now
Searches for an exact ACMX passing score usually assume the exam is open for registration today. It isn't. HPE's certification catalog currently lists Aruba Certified Mobility Expert (ACMX) as inactive, which changes the entire framing of this question. There is no live, scheduled version of this credential sitting in the HPE credential management platform waiting for you to book through Pearson VUE, and no published cut score attached to a currently open exam.
That doesn't mean the underlying technical content is worthless. Complex enterprise Aruba mobility design, deployment, authentication, roaming, network security, management, and troubleshooting knowledge remains directly relevant to real-world Aruba deployments and to other credentials in HPE's networking track. But it does mean this article has to do something most "passing score" posts don't: separate historical written-exam mechanics from any implication that you can register for ACMX in 2026 and receive a fresh numeric target.
How Aruba Expert-Level Exams Were Scored
Expert-level Aruba exams, including the written component historically associated with the ACMX track, were not graded on a simple "70% correct equals pass" model. HPE's proctored exams - administered through the HPE credential management platform and delivered via Pearson VUE - commonly use scaled scoring on expert-tier exams. That means your raw number of correct answers is converted into a scaled score, and the specific conversion can shift slightly between exam forms to account for item difficulty.
Practically, this is why you'll rarely find a single trustworthy number like "you need exactly X out of Y correct" floating around for any Aruba expert exam, ACMX included. Anyone publishing a precise universal cut score for an inactive exam is guessing, not reporting fact. If you want a realistic sense of how tough the content itself is - independent of the exact scoring curve - the breakdown in How Hard Is the ACMX Exam? Complete Difficulty Guide 2026 is a better starting point than chasing a phantom percentage.
Key Takeaway
Treat any specific "you need 720/1000" style claim about ACMX with skepticism unless it's sourced directly from HPE's own datacard - scaled scoring on expert exams varies by form, and the credential itself is currently inactive.
HPE6-A79: The Legacy Written Exam Reference
The written-exam identifier most closely tied to this credential family is HPE6-A79. This is a legacy datacard reference, not an active enrollment page you should be booking a seat against today. If you're doing historical research or working through old study notes, HPE's own datacard for HPE6-A79 is the only authoritative place to check what that exam actually specified, since third-party recaps age quickly and drift from the source.
It's worth separating three things that often get blurred together in older forum threads and outdated blog posts:
- The written exam (HPE6-A79) - knowledge-based, multiple-choice/scenario style questions on mobility design and operations.
- Practical lab requirements - hands-on validation historically expected at the expert tier, distinct from the written exam's scoring mechanics.
- Current certification requirements - whatever HPE's live catalog lists today, which may look nothing like the legacy ACMX structure.
Mixing these up is exactly how outdated "passing score" numbers end up recycled onto pages that no longer describe reality. For a full breakdown of what each domain historically covered, see ACMX Exam Domains 2026: Complete Guide to All Content Areas.
Domain Coverage and Why It Mattered for Scoring
Even without a public percentage-by-domain breakdown, the subject areas the written exam drew from are consistent with what expert-level Aruba mobility engineers are expected to know cold. Scaled scoring aggregates performance across the full question pool, so weak performance in any one of these areas could meaningfully drag down an otherwise strong attempt.
Complex Enterprise Mobility Design
Multi-site, multi-controller architecture decisions, capacity planning, and RF design tradeoffs at scale.
- Design patterns for large campus and branch deployments
- Redundancy and failover planning across controllers
Deployment and Configuration
Turning a design into a working configuration across ArubaOS-managed infrastructure, with version-specific behavior differences noted where relevant.
- Staged rollout and validation practices
- Configuration consistency across sites
Authentication, Roaming, and Security
Enterprise authentication flows, secure roaming between APs and controllers, and policy enforcement for mobile clients.
- 802.1X and role-based access control scenarios
- Fast roaming mechanisms and their tradeoffs
Management and Troubleshooting
Centralized management workflows and structured troubleshooting methodology for complex, multi-layer mobility issues.
- Log and diagnostic interpretation
- Root-cause isolation across wired/wireless boundaries

Legacy ACMX vs. the Current HPE Certification Path
Because the passing-score question only makes sense in context, here's how the legacy ACMX credential compares to how HPE structures active certifications today.
| Aspect | Legacy ACMX | Current HPE Certification Path |
|---|---|---|
| Catalog status | Listed as inactive | Actively maintained and updated by HPE |
| Registration | Not open for new candidates | Booked via HPE credential management platform + Pearson VUE |
| Passing score source | No current published figure (historical scaled scoring only) | Defined per active exam in the current catalog |
| Written exam reference | HPE6-A79 (legacy datacard) | Current exam codes listed in HPE's technical certifications catalog |
| Community support | Older Airheads threads, archived material | Active Airheads discussions on current tracks |
If You're Studying Legacy Material Anyway
Some readers land here because they've already started working through ACMX-labeled practice questions and study guides - often for background knowledge, interview prep, or because they're refreshing skills that transfer to a newer Aruba credential. If that's you, structure the review around the domains above rather than around a numeric score target you can't verify.
Design and Architecture Review
- Rebuild multi-site design scenarios from memory
- Note where ArubaOS version differences change the "right" answer
Authentication and Roaming Deep Dive
- Walk through 802.1X and role-based policy flows end to end
- Drill fast-roaming mechanics until they're second nature
Security and Management Consolidation
- Cross-reference policy enforcement with troubleshooting logs
- Practice explaining root-cause findings out loud, not just recognizing them
Full Scenario Runs
- Combine design, security, and troubleshooting into single case studies
- Review the full method in ACMX Study Guide 2026: How to Pass on Your First Attempt

How to Verify What's Actually Current
Before spending money or scheduling time around any Aruba credential, confirm status directly rather than trusting secondhand recaps:
- Check HPE's certification and learning site for the live technical certifications catalog.
- Look up any specific exam code's datacard directly rather than relying on summaries.
- Confirm registration mechanics through the HPE credential management platform and Pearson VUE's HPE program page.
- Remember that general OnVUE at-home testing availability statements explicitly exclude Aruba Expert exams - that exclusion applies here and should not be read as confirming or denying ACMX availability either way.
- For training and hands-on labs tied to current material, HPE Networking Education Services and the Airheads community are the right places to look, not archived ACMX threads.
If you're mapping out prerequisites or eligibility for whatever credential you land on, ACMX Requirements 2026: Eligibility, Prerequisites & How to Qualify covers what historically applied at this tier, and ACMX Certification Cost 2026: Complete Pricing Breakdown puts legacy fee structure in context so you're not budgeting against outdated assumptions.

FAQ
There isn't a current one to report. HPE's catalog lists ACMX as inactive, so no live exam session is generating a fresh, verifiable cut score right now. Historical Aruba expert exams used scaled scoring rather than a flat percentage, and that scaling could vary by exam form.
HPE6-A79 is the written-exam datacard reference associated with this credential family, but it should be treated as a legacy reference point rather than an active registration path. Always check HPE's own datacard for the most accurate current status.
HPE's general OnVUE availability statement specifically excludes Aruba Expert exams, and that exclusion doesn't establish whether ACMX itself is available in any format. With the credential listed as inactive, this question is largely moot for new candidates.
If your goal is deepening real-world Aruba mobility skills - design, authentication, roaming, security, and troubleshooting - the underlying content is still useful. Just don't treat old practice questions as a current exam blueprint; check the domains guide for how the content maps to real skills.
Go directly to HPE's current technical certifications catalog and HPE Networking Education Services for training, and use the Airheads community for peer discussion on whichever active credential you choose.
