100+ Free Blue Prism Pro Developer Practice Questions

The Blue Prism Professional Developer exam (exam code AD01) is the advanced developer certification from SS&C Blue Prism. It validates expertise in building production-grade RPA solutions including complex process design, work queue architecture, exception handling strategies, VBO object-oriented design, and integrations with external systems (databases, SOAP, REST). It is typically taken after gaining experience with the Blue Prism Developer credential.

The AD01 is considered advanced difficulty. It requires deep practical knowledge of Blue Prism — not just basic process creation but architectural decision-making: when to use environment locks vs. tags, how to design resilient exception strategies, how to configure work queues for the dispatcher-performer pattern, and how to securely handle credentials and environment variables. Candidates typically need 6-12 months of hands-on Blue Prism experience before attempting it.

The exam covers: Robotic Operating Model (ROM) roles and documentation (PDD, SDD); advanced process design (templates, state, startup parameters); Visual Business Object (VBO) design using OO principles; Work Queue features (priority, SLA dates, tags, defer, auto-retry, environment locks); exception handling (Block/Recover, system vs business exceptions, re-throw); Code Stages in VB.NET/C#; integrations (SOAP web services, REST APIs, SQL databases, MAPIEx); Credential Manager and environment variables; Login Agent; and logging configuration.

The Blue Prism Professional Developer (AD01) exam typically contains around 60 multiple-choice questions with a 1.5-hour time limit. The passing score is 70%.

A System Exception indicates an unexpected technical failure — the application behaved unexpectedly (element not found, timeout, connection error). A Business Exception is a planned exception — the application worked correctly but the data doesn't meet business rules (duplicate invoice, missing field). They are handled differently: business exceptions typically skip the item and mark it as a known exception; system exceptions often trigger retries or escalation. The AD01 exam tests this distinction extensively.

The Dispatcher-Performer pattern is a core Blue Prism scalability design. A Dispatcher process reads source data (e.g., from a spreadsheet or database) and loads items into a work queue. Multiple Performer robots simultaneously pick up and process items from the queue. This decouples data loading from processing, enables parallel scale-out by adding more Performer robots, and provides built-in retry, SLA tracking, and audit capabilities through the work queue.

Environment Locks provide a named mutex mechanism for coordinating exclusive access to shared resources. A robot acquires a named lock before accessing a shared resource (e.g., a single-seat application, shared file, printer). Other sessions attempting the same lock wait until it is released. Locks have a configurable timeout — if a session crashes while holding a lock, the server automatically releases it after the timeout, preventing permanent deadlock.
