The ACD201 exam validates your expertise as an Appian Certified Senior Developer within the Appian Certification Program. This credential demonstrates your ability to design, build, and optimize enterprise applications on the Appian platform at an advanced level. This page outlines the exam structure, core topics, and practical preparation strategies to help you succeed. Whether you're advancing your career or deepening your technical foundation, understanding what ACD201 measures is the first step toward confident test day performance.
Use this topic map to guide your study for Appian ACD201 (Appian Certified Senior Developer) within the Appian Certification Program path.
ACD201 measures both conceptual knowledge and practical decision-making through varied question types. Each format tests your ability to apply Appian principles in realistic development scenarios.
Questions progress in difficulty, requiring you to connect concepts across design, development, and operations to reflect real-world application delivery.
An effective study plan maps each topic area to dedicated study blocks, allowing time for hands-on practice and concept review. Allocate 4-6 weeks to balance breadth across all five domains while reinforcing weaker areas through targeted practice.

Advanced Appian Concepts and Performance and Scalability typically account for a larger portion of the exam, reflecting their importance in real-world senior developer roles. However, all five domains are tested, so balanced preparation across all topics is essential. Prioritize deeper understanding of advanced topics while maintaining solid foundational knowledge in the other three areas.
These three topics form the core development workflow: you design applications (Application Design and Development), structure and secure data (Data Management), and then deploy and maintain them in production (Platform and Application Management). Understanding how decisions in one area affect the others is crucial for answering scenario-based questions correctly. For example, a data model choice impacts both query performance and how you configure environments for optimal throughput.
Practical experience building at least two to three complete applications on Appian is recommended, including designing interfaces, writing rules and process models, integrating data sources, and deploying to production. Focus on projects where you've had to optimize performance, troubleshoot issues, and manage application versions. Lab exercises covering all five topic areas will fill gaps if your project experience is limited in certain domains.
Many candidates underestimate the depth of Advanced Appian Concepts and Performance and Scalability, treating them as secondary topics. Others rush through scenario questions without fully analyzing the business context and constraints, leading to suboptimal design choices. Additionally, some candidates confuse similar features or configuration options without understanding when to apply each one. Slow down on scenario items, reread requirements, and practice explaining your reasoning for each answer choice.
Review high-weight topics and revisit any practice questions you answered incorrectly, focusing on understanding the underlying concepts rather than memorizing answers. Take one full-length timed practice test to assess your readiness and identify remaining weak areas. Avoid cramming new material in the last two days; instead, use that time to review notes, build confidence, and ensure you're well-rested before test day. Trust your preparation and approach each question methodically.
You're creating a new entity-backed record type without data sync enabled. Users in the "ACME Supervisors" group must be able to access the Delete Case related action on the record summary view.
What are two valid steps that you should perform to grant users the appropriate access?
Adding 'ACME Supervisors' as members of 'Database Editors' with DELETE privileges allows them to perform delete operations.
Updating the 'Delete Case' record action security and including 'ACME Supervisors' in the visibility settings ensures they have access to the related action on the record summary view.
You need to configure Appian user authentication against an external directory server. The requirement is to use the same corporate logon information without single sign-on (SSO).
Which authentication type should you use?
LDAP authentication allows users to log in with their corporate credentials by authenticating against an external directory server, without requiring single sign-on (SSO).
You're maintaining a client's case management system.
The client needs you to review the performance of one of their interfaces as it is perceived to be quite slow
The interface is a start form that users use to edit party records in the system. They can edit these party records either through the participant view of the case record or directly through the party record.
Given a party record may consist of many attributes, Custom Data Types (CDT) have been used for the purpose of writing to the database, while record types have been used to retrieve data.
What might be a potential cause for this issue, and what should you do?
You have set up SAML for single sign-on (SSO) in your cloud environment.
Which three options could you enable in the Attribute Mapping section of the Admin Console to sync with a user's profile in Appian? (Choose three.)
Create new users upon sign in - provisions new Appian users automatically when they first authenticate through SAML.
Reactivate deactivated users upon sign in - automatically re-enables an Appian account if the user returns after being deactivated.
Update user attributes upon sign in - refreshes profile details (e.g., name, email, custom attributes) each time the user signs in.
An application consists of a record type with sync enabled. This record type is used as a source to create a read-only grid.
A field "Number of days since created" is configured in the interface and a logic is implemented to calculate the number of days since a record is created in the application.
You need to implement sorting on this field.
What should you do?
Creating a custom record type field to calculate 'Number of days since created' allows you to use this field in the sorting configuration of your read-only grid.
