Question 1 of 71

A junior developer is trying to make a reusable object so that a record status will show up as an icon with a specific color.
If no status is designated, then "N/A" should display. They have already created relevant constants for all status values and colors needed. This status will be used both on the record list and within the record summary view.
Which strategy should you recommend?

Create an interface that includes an a!match(), which is used to select a a!iconIndicator() or defaulted a!richTextItem("N/A") based on a rule input made for the value parameter of the a!match().

Create an expression that includes a a!richTextDisplayField(), where a!match() is used to select a a!richTextIcon() or defaulted a!richTextItem("N/A") based on a rule input made for the value parameter of the a!match().

Create expressions for each a!richTextIcon() option with appropriate constants. Use an a!match() in the target interface to choose from the icon expressions or a!richTextItem("N/A"), based on the target data's status.

Question 2 of 71

You have an external system where data is exposed through a REST API endpoint. You have created a service-backed record type that connects to this external system, and configured a record data source expression and a sync expression. You have also configured syncing in batches.
When initiating a full sync of the record type for the first time, the sync fails and returns the following error:
“Unable to sync due to an error in the Record Data Source during batch number 1,026.”
After performing a direct query with an API analyzer such as Postman, you see that the external system returns an “416 Undefined” error at 1,026, indicating that there are no more records to be synced.
When the API returns a “416” error, how should you handle this error in the record data source expression and ensure the full sync on the record type completes successfully?

Return an empty record type constructor.

Return an empty list.

Return an empty integration response.

Question 3 of 71

A large manufacturing company is looking to build their first Appian application.
They want to improve efficiency and productivity across various departments, but they also want to start with a manageable project that will quickly demonstrate the value of Appian.
Which idea should you recommend for the company's first Appian project?

A comprehensive enterprise resource planning (ERP) system that coordinates all business processes and data across the company.

A customer relationship management (CRM) system that centralizes customer data and automates sales and marketing processes

A departmental expense approval application that streamlines the expense submission and approval process for employees and managers.

The Support Tickets source table has approximately two (2) million rows of data over the current sync limit, with statuses of either “Open” or “Closed.”
The organization needs to view, report, and take action on “Open” tickets in Appian, and have the ability to retain access to “Closed” tickets for audit purposes.
Which data structure should you recommend?

Two synced record types, one for “Open” tickets and one for “Closed” tickets, with sync filters enabled.

One synced record type for “Open” tickets, with sync filters enabled, and one unsynced record type for all tickets.

One synced record type on the Support Ticket source table, with the setting Keep data available at high volumes enabled.
