ACCAM Exam Domains 2026: Complete Guide to All 5 Content Areas

Exam Overview: What AD0-E328 Actually Tests

The Adobe Campaign Classic Architect Master credential is validated through exam AD0-E328. It's an English-language exam with a 1 hour 40 minute time limit and a published passing criterion of 30 out of 50 scored questions. Adobe's general policy also permits up to 10 additional unscored questions mixed into any exam, which means the item count you see on screen can run higher than the 50 that actually count toward your score.

Unlike associate-level Campaign Classic exams that lean heavily on tool navigation, AD0-E328 is built around five domains that mirror the actual responsibilities of an architect: defining a solution before a single workflow is built, mapping and governing the data that feeds every campaign, standing up and maintaining the platform itself, leading the delivery of the project, and customizing Campaign Classic to fit requirements the out-of-box tool doesn't cover. If you're still deciding whether this exam is the right next step, our overview of What Is ACCAM Certification? and the broader ACCAM Certification page are good starting points before you dive into domain-level prep.

Domain 1: Solution Definition (24%)

Solution Definition sits at 24% of the exam and covers the architect's role before implementation begins: translating business requirements into a Campaign Classic solution design, evaluating constraints, and making defensible architectural decisions. This is where the exam checks whether you can think like someone who has actually scoped multiple Campaign Classic implementations, not just someone who memorized menu paths.

Because this domain is scenario-heavy, rote memorization of feature lists won't get you far. If you want a condensed pass on the terminology and decision criteria this domain draws on, the ACCAM Cheat Sheet 2026: One-Page Review of Must-Know Facts is a useful companion once you've done the deeper reading.

Domain 2: Data Landscaping (24%)

Tied with Solution Definition at 24%, Data Landscaping is about understanding how data flows into, through, and out of Campaign Classic. Architects are expected to know how to map source systems, design the schema, and plan for data governance and quality at scale - not just how to build a single workflow that imports a file.

This domain rewards candidates who have actually planned data architecture for a live implementation, since exam scenarios tend to present messy, multi-source situations rather than clean textbook examples.

Domain 3: Installation and Management (16%)

Installation and Management covers the operational side of running Campaign Classic: setup, configuration of the platform environment, ongoing administration, and the kind of maintenance decisions an architect signs off on even if they're not the one executing them day to day.

At 16%, this domain is smaller than the top two, but it's still worth roughly one in every six or so questions. Candidates coming from a pure consulting background sometimes underestimate this domain because it's less glamorous than solution design - that's exactly the gap worth closing early.

Domain 4: Project Leadership (10%)

Project Leadership is the lightest domain at 10%, but don't mistake "smallest" for "skippable." This section evaluates whether you understand the architect's role in guiding a project team, managing stakeholders, and making delivery-level decisions that keep an implementation on track.

Because this domain is worth only 10%, it typically deserves the least raw study time of the five - but a handful of missed questions here can still be the difference between passing and retaking. For a broader sense of how difficulty is distributed across the whole exam, see How Hard Is the ACCAM Exam? Complete Difficulty Guide 2026.

Domain 5: Customization (26%)

Customization is the single largest domain at 26%, making it the highest-leverage area of preparation. This is where the exam tests your ability to extend Campaign Classic beyond its out-of-box capabilities - scripting, custom workflow logic, API-driven integrations, and template or delivery customization.

How to Weight Your Study Time Against the Blueprint

With five domains and uneven weighting, the most efficient prep plan allocates time roughly proportional to exam weight, then leaves a buffer for whichever domain feels weakest personally. A simple way to visualize this:

A practical sequencing approach is to open your study plan with Customization and Solution Definition since together they cover half the exam and tend to require the most hands-on practice, then move into Data Landscaping while those concepts are fresh, and finish with Installation and Management and Project Leadership as consolidation topics closer to your test date.

Registration, Fees, and Exam-Day Mechanics

Exam AD0-E328 costs USD 225 globally or USD 150 in India. Eligible Adobe partner employees and verified students qualify for a 33% discount, and Adobe employees pay a reduced USD 80. Every attempt requires a new fee - there's no bundled retake included in the initial price. For a full breakdown of these numbers alongside what they mean for your budget, read ACCAM Certification Cost 2026: Complete Pricing Breakdown.

If you don't pass on your first attempt, Adobe's retake policy requires a 24-hour waiting period before scheduling again; a second or subsequent failure extends that wait to 15 calendar days. Given that each retake costs the full fee again, it's worth reviewing the domain breakdown above carefully before you book your first attempt rather than treating the exam as a diagnostic run.

The exam is delivered via Excelsoft easyProctor, which requires a system check, valid photo identification, camera access, and screen sharing during the session. Returning candidates who previously used Guardian Browser are directed to uninstall it before testing again - a detail easy to miss until exam day. Adobe's own preparation resources are the EPG-E328 exam prep guide and the AD4-E328 practice test, which candidates typically use alongside independent domain review.

Adobe recommends three to five years of relevant experience and multiple Campaign Classic implementations before attempting this exam; formal training is not mandatory, though it can shorten the learning curve for candidates newer to the platform. If you're unsure whether your background meets the bar, check ACCAM Requirements 2026: Eligibility, Prerequisites & How to Qualify before committing to a test date.

Once you understand exactly what the passing threshold looks like against the 50 scored questions, it's easier to plan how much margin you need per domain - our ACCAM Passing Score 2026: Exactly What You Need to Pass breaks that down further, and ACCAM Pass Rate 2026: What the Data Shows covers what's publicly known about outcomes. For candidates weighing whether the investment pays off in career terms, Is the ACCAM Certification Worth It? Complete ROI Analysis 2026 and ACCAM Salary Guide 2026: Complete Earnings Analysis are worth reading alongside this domain guide, and ACCAM Jobs gives a sense of where this credential shows up in hiring. You can also test your current domain-by-domain readiness directly on our practice exam before booking your official attempt.
