PDEV02 exam questions

1. Question 1

   Multiple answer

   In a tenancy-renewal process, a sub-page runs six stages in order and has no Recover stage. On the calling page, the Page stage that calls the sub-page sits inside a Block that also contains a Recover stage and a Resume stage. An exception is raised at the third stage of the sub-page.

   Which two statements describe what happens next?

   (Choose two.)

   • A

     The session terminates with the exception unhandled at the sub-page that raised it

   • B

     The Recover stage inside the Block on the calling page catches the exception

   • C

     After the Resume stage, flow returns to the fourth stage of the sub-page

   • D

     Stages four to six of the sub-page do not run for this call

   • E

     Blue Prism skips the calling page and hands the exception to the Main page's recovery

   Reveal answer

   Correct answer

   • B

     The Recover stage inside the Block on the calling page catches the exception

   • D

     Stages four to six of the sub-page do not run for this call

   Explanation

   With no Recover on the sub-page, the exception passes up to the stage that called it. That Page stage sits in the Block, so the Block's Recover catches it.

   Once the exception leaves the sub-page, that call is abandoned. Recovery continues on the calling page, so any clean-up placed later on the sub-page is skipped and must be handled by the caller's recovery path.

2. Question 2

   Single answer

   A medical-device parts supplier's order API returns a nested JSON body. Four processes call it through a Web API Service action whose only output is the raw response text, and each process then converts that text into a Collection and reads order.status and the order.lines array from it.

   What is the BEST change?

   • A

     Add output parameters to the action that map order.status and order.lines with JSON Path, and drop the conversion in all four processes

   • B

     Move the text-to-Collection conversion into one shared utility object action that all four processes call after the request

   • C

     Request an XML response from the supplier instead and read it straight into a Collection with no conversion step

   • D

     Keep the raw text output and extract both fields in each process with a RegEx action from a utility object

   Reveal answer

   Correct answer

   • A

     Add output parameters to the action that map order.status and order.lines with JSON Path, and drop the conversion in all four processes

   Explanation

   An action's output parameters can be mapped from the response body with JSON Path, so each caller receives the status and lines directly and the parsing lives once, in the service. A later change to the mapping is a single edit.

3. Question 3

   Single answer

   A developer is writing an external utility that will add items with Item Data to a Work Queue through the Blue Prism API. They are unsure which fields the request body requires in the version their organization has installed.

   Where should they confirm the request's shape?

   • A

     A request body copied from a forum post written for an earlier release

   • B

     The inputs of the Work Queues business object's Add To Queue action

   • C

     The API specification published with the installed version

   • D

     The columns that Control Room shows for that queue's item list

   Reveal answer

   Correct answer

   • C

     The API specification published with the installed version

   Explanation

   Each release publishes an API specification describing every operation's request and response. It is the authoritative, version-matched source.

5. Question 4

   Single answer

   A loader adds claims to one Work Queue and tags each claim as Standard or Complex. A separate worker process must work only the Complex claims.

   How should that worker process retrieve its items?

   • A

     Call Get Next Item with no filter and skip any item that is not tagged Complex

   • B

     Call Get Next Item with a Tag filter that returns only the Complex items

   • C

     Sort the queue in Control Room so Complex items come first

   • D

     Give Complex items a higher priority so the worker gets only those

   Reveal answer

   Correct answer

   • B

     Call Get Next Item with a Tag filter that returns only the Complex items

   Explanation

   Get Next Item can filter on Tags, so it returns only pending items tagged Complex and never locks a Standard claim.

6. Question 5

   Single answer

   A critical process must keep working if one Digital Worker becomes unavailable.

   Which design supports this?

   • A

     Several Digital Workers sharing one Work Queue

   • B

     One dedicated Digital Worker running the process on a fixed schedule

   • C

     Exception handling disabled across the process and its objects

   • D

     One Digital Worker per item type, each with its own separate queue

   Reveal answer

   Correct answer

   • A

     Several Digital Workers sharing one Work Queue

   Explanation

   Each item is locked to one worker, so if one Digital Worker drops out, the others keep pulling from the shared queue.
