- HPE announced the phaseout of ClearPass Associate, Professional, and Expert certifications in December 2022.
- The historical ACCX exam was an eight-hour hands-on practical covering design decisions and working implementations.
- Candidate skill areas spanned Policy Manager, Guest, Onboard, OnGuard, profiling, posture, and multi-server deployments.
What Is ACCX, Exactly?
ACCX stands for Aruba Certified ClearPass Expert, a career-track certification issued through Hewlett Packard Certification and Learning under Hewlett Packard Enterprise / Aruba. It sat at the top of the ClearPass certification ladder, above the Associate and Professional levels, and was designed to validate that a candidate could design, deploy, and troubleshoot ClearPass Policy Manager environments at an expert level, not just answer multiple-choice questions about features.
If you've landed here searching for "what is a ACCX," it's worth pinning down this identity early: this page is exclusively about the Aruba ClearPass credential. Other acronyms that look similar belong to entirely different certifying bodies and have nothing to do with network access control, ClearPass Policy Manager, or Aruba's security stack. For a deeper breakdown of the name itself, see our companion piece on ACCX meaning and the related explainer on what ACCX stands for.
Current Status: Why ACCX Was Retired
ACCX is a retired career credential. In December 2022, HPE announced the phaseout of the ClearPass Associate, Professional, and Expert certifications as part of a broader expansion of the Network Security certification track. This wasn't a rebrand of ACCX under a new name - it was a structural shift in how HPE Aruba Networking organizes its security certifications going forward.
That means there is no active booking process, no current exam fee schedule, and no live testing window for ACCX today. Anyone searching for registration steps or a scheduling portal for ACCX specifically is looking for something that no longer exists as an active offering. If your goal is passing a currently bookable exam, you'll want to look at HPE's present-day tracks instead - but if your goal is understanding ClearPass at an expert level, or you're researching this credential for historical, resume-verification, or skills-building reasons, the underlying technical material is still extremely relevant.
Key Takeaway
Treat any ACCX content you find today - including this site's practice material - as legacy certification content and product-skills training, not as a live exam booking offer.
Who Pursued (and Still Studies) ACCX
Historically, ACCX candidates were network security engineers, senior network administrators, and NAC (network access control) specialists who already had hands-on ClearPass deployment experience before attempting the exam. This was not an entry-level credential. HPE's guidance for the exam described a candidate profile comfortable with production-scale, multi-server ClearPass architectures - not someone who had only completed a lab guide once.
People studying ACCX material today generally fall into a few groups:
- Engineers who earned ACCX before the 2022 phaseout and want reference material or troubleshooting scenarios to keep skills sharp.
- Job seekers whose resumes list ACCX and want to be ready to explain the technical depth behind it in interviews.
- Network security professionals using ClearPass in production who want expert-level scenario practice regardless of certification status.
- Students exploring whether ACCX certification is worth pursuing as a concept, even in its retired form, before choosing a current-track alternative.
If you're mapping out career relevance, our ACCX jobs overview and ACCX salary guide discuss how this background is viewed by employers who run ClearPass in production.
The Eight-Hour Practical: How ACCX Was Tested
What made ACCX distinctive - and genuinely difficult - was its exam format. According to historical HPE employee guidance, the ACCX assessment was an eight-hour, hands-on practical exam, not a timed multiple-choice test. Candidates had to make real design decisions and produce working implementations inside live ClearPass environments.
This format tested things a question bank simply cannot:
- Whether a candidate could architect a multi-server ClearPass deployment that actually functioned under given constraints.
- Whether policy, role mapping, and enforcement decisions held up once traffic and authentication requests were flowing.
- Whether the candidate could diagnose and fix a broken configuration under time pressure, not just recognize the "correct" answer from a list.
For anyone trying to gauge just how demanding this was relative to expectations, our article on ACCX passing score walks through how expert-level practical exams like this were evaluated, and how that differs from a simple percentage cutoff.
The Technical Content Areas Behind ACCX
ACCX's practical exam drew from a well-defined set of ClearPass technical domains. If you're building a study plan - even an informal one for skills development - these are the areas that mattered:
Deployment and Clustering
Candidates needed to understand multi-server ClearPass cluster architecture, redundancy, and how Policy Manager nodes coordinate policy enforcement across a deployment.
- Publisher/subscriber cluster relationships
- Sizing and redundancy planning for production environments
Authentication Sources and Role Mapping
ACCX required fluency in connecting ClearPass to identity stores and translating authentication results into meaningful roles.
- Configuring multiple authentication sources
- Building role mapping policies that feed downstream enforcement
Enforcement Policy
Turning authentication and role data into actual network behavior was central to the practical exam's "working implementation" requirement.
- Enforcement profiles and policy chaining
- Conditions based on device, role, and posture state
Guest Workflows
ClearPass Guest configuration - from self-registration to sponsor approval flows - was part of the expected candidate skill set.
- Guest self-registration and sponsor-based workflows
- Guest network access policy integration with core enforcement
Certificates and BYOD (Onboard)
Onboard-driven BYOD flows required candidates to understand certificate provisioning end to end.
- Certificate authority integration and provisioning workflows
- Device onboarding policy design for BYOD scenarios
Endpoint Posture and Profiling (OnGuard)
OnGuard posture checks and device profiling were core to demonstrating expert-level policy design.
- Posture policy configuration and remediation actions
- Device profiling accuracy and fingerprinting behavior
Integrations and Troubleshooting
Because the exam was hands-on, the ability to troubleshoot a broken multi-component deployment mattered as much as building one from scratch.
- Third-party integration points (switches, controllers, MDM)
- Diagnosing failed authentication, enforcement, or posture checks
For a full walkthrough of how these areas fit together conceptually, see our ACCX exam domains guide, which maps each content area to the kind of scenario you'd realistically face in a practical assessment.
What Replaced ACCX at HPE Aruba Networking
Since the December 2022 phaseout announcement, HPE Aruba Networking has organized its current security certifications differently. Two current offerings are relevant to anyone coming from a ClearPass background, and it's important to keep them conceptually separate from ACCX rather than assuming exam specs carry over:
| Credential | Nature | Relationship to ACCX |
|---|---|---|
| HPE Advanced Product Certified - ClearPass | Current product-focused certification | Successor track; not a direct continuation of ACCX's format or scope |
| HPE Aruba Networking Certified Expert - Network Security | Current expert-level security certification | Part of the broader Network Security track that ACCX was folded into |
| ClearPass Advanced Configuration course | Skills training, explicitly not certification prep | Useful for ClearPass skills, but does not map to any ACCX exam blueprint |
Key Takeaway
Don't assume the current HPE Advanced Product Certified - ClearPass exam or the Network Security Expert track shares ACCX's exact eight-hour practical format - treat them as distinct, current-generation credentials.
Why Study Legacy ACCX Material Today
Even though ACCX itself can no longer be booked, the underlying ClearPass expertise it validated hasn't gone anywhere. Organizations running Policy Manager, Guest, Onboard, and OnGuard in production still need engineers who can design clusters, write enforcement policy, and troubleshoot posture failures under pressure. That's exactly the skill set ACCX was built to prove.
This is why our practice material on the main ACCX practice test platform is framed as legacy certification content and product-skills training rather than a live exam booking service. The scenarios mirror the kind of design decisions and troubleshooting problems that appeared in the original eight-hour practical - useful whether you're preparing for a current HPE exam, maintaining ClearPass in your job, or simply want to validate expert-level ClearPass knowledge for your own resume.
If you want the full picture of how this credential fits into a broader career decision, our ACCX certification overview and ACCX requirements article cover the prerequisite experience HPE expected candidates to already have before attempting the practical.
Approaching the Material Efficiently
Because ACCX's real exam was scenario-based rather than recall-based, the most effective preparation mirrors that structure: work through configuration problems domain by domain instead of memorizing flashcards.
Deployment and Authentication Foundations
- Build a multi-server cluster mentally or in a lab
- Configure multiple authentication sources and role mapping
Enforcement, Guest, and Onboard
- Write enforcement profiles tied to role and posture conditions
- Practice guest self-registration and certificate-based BYOD flows
Posture, Profiling, and Troubleshooting
- Configure OnGuard posture checks and remediation actions
- Run deliberate troubleshooting drills on broken configs
Our ACCX study guide expands on this sequencing with scenario-specific practice, and the ACCX cheat sheet condenses the must-know configuration facts into a single reference page. If you're benchmarking your own readiness, the ACCX pass rate article discusses what the available data actually shows, without inflating numbers that weren't part of the historical record.
Frequently Asked Questions
No. HPE announced the phaseout of ClearPass Associate, Professional, and Expert certifications in December 2022 as its Network Security certification track expanded. ACCX is a retired credential, though the underlying ClearPass skills remain highly relevant.
Historical HPE guidance describes ACCX as an eight-hour hands-on practical exam requiring real design decisions and working implementations across Policy Manager, Guest, Onboard, OnGuard, profiling, and posture in multi-server deployments - not a question bank.
HPE currently offers HPE Advanced Product Certified - ClearPass and HPE Aruba Networking Certified Expert - Network Security. These are distinct, current-generation credentials and shouldn't be assumed to share ACCX's exact exam blueprint.
The technical skills ACCX validated - clustering, authentication, role mapping, enforcement, guest workflows, certificates, posture, and troubleshooting - are still used daily in production ClearPass environments, so this content is preserved as legacy study and skills-training material.
Network security engineers and NAC specialists with existing hands-on ClearPass deployment experience, since the practical exam assumed familiarity with production-scale, multi-server architectures rather than introductory knowledge.
