Read the first 7 Automate Business Processes with Power Automate flashcards as text

  1. A developer is building a flow that must call an on-premises REST API. Which component is required to enable this connectivity from a cloud flow?

    Answer: On-premises data gateway

    The on-premises data gateway acts as a secure bridge between Power Automate cloud flows and on-premises resources.

  2. In Power Automate, which expression function checks whether a string contains a specific substring and returns a Boolean?

    Answer: contains()

    The `contains()` function returns true if the specified string includes the given substring.

  3. A developer wants to limit a cloud flow so that no more than 5 instances run simultaneously. Where is this setting configured?

    Answer: Trigger settings > Concurrency Control

    Concurrency Control in the trigger settings allows developers to set a maximum degree of parallelism for simultaneous flow runs.

  4. A flow exports Dataverse records to a CSV file. The developer uses 'Create CSV table' action. Which input must be provided to this action?

    Answer: An array of objects

    The 'Create CSV table' action requires an array of objects (typically from a 'List rows' action), with each object becoming a CSV row.

  5. When a Power Automate flow uses the HTTP action to call an external API with a JSON body, which header must be set to ensure the API interprets the request body correctly?

    Answer: Content-Type: application/json

    The `Content-Type: application/json` header tells the receiving API that the request body is JSON-formatted.

  6. A developer needs to loop through Dataverse records until a field value condition is met, with a maximum iteration cap. Which action is most appropriate?

    Answer: Do Until

    'Do Until' repeats actions until a specified condition is true, and has a built-in count and timeout limit to prevent infinite loops.

  7. A team wants to share a cloud flow so that another user can edit it but the original owner retains run history visibility. Which sharing permission level should be assigned?

    Answer: Co-owner

    Co-owner permission grants the ability to edit the flow while both the owner and co-owner can view run history.
