An existing integration is implemented in Appian. Its role is to send data for the main case and its related objects in a complex JSON to a REST API, to insert new information into an existing application. This integration was working well for a while. However, the customer highlighted one specific scenario where the integration failed in Production, and the API responded with a 500 Internal Error code. The project is in Post-Production Maintenance, and the customer needs your assistance. Which three steps should you take to troubleshoot the issue?

• A. Obtain the JSON sent to the API and validate that there is no difference between the expected JSON format and the sent one.
• B. Analyze the behavior of subsequent calls to the Production API to ensure there is no global issue, and ask the customer to analyze the API logs to understand the nature of the issue.
• C. Ensure there were no network issues when the integration was sent.
• D. Send a test case to the Production API to ensure the service is still up and running.
• E. Send the same payload to the test API to ensure the issue is not related to the API environment.

As part of an upcoming release of an application, a new nullable field is added to a table that contains customer dat a. The new field is used by a report in the upcoming release and is calculated using data from another table.
Which two actions should you consider when creating the script to add the new field?

• A. Create a script that adds the field and then populates it.
• B. Create a script that adds the field and leaves it null.
• C. Add a view that joins the customer data to the data used in calculation.
• D. Create a rollback script that clears the data from the field.
• E. Create a rollback script that removes the field.

As part of your implementation workflow, users need to retrieve data stored in a third-party Oracle database on an interface. You need to design a way to query this information.
How should you set up this connection and query the data?

• A. Configure an expression-backed record type, calling an API to retrieve the data from the third-party database. Then, use a!queryRecordType to retrieve the data.
• B. Configure a Query Database node within the process model. Then, type in the connection information, as well as a SQL query to execute and return the data in process variables.
• C. Configure a timed utility process that queries data from the third-party database daily, and stores it in the Appian business database. Then use a!queryEntity using the Appian data source to retrieve the data.
• D. In the Administration Console, configure the third-party database as a "New Data Source." Then, use a!queryEntity to retrieve the data.

While working on an application, you have identified oddities and breaks in some of your components. How can you guarantee that this mistake does not happen again in the future?

• A. Create a best practice that enforces a peer review of the deletion of any components within the application.
• B. Ensure that the application administrator group only has designers from that application's team.
• C. Provide Appian developers with the "Designer" permissions role within Appian. Ensure that they have only basic user rights and assign them the permissions to administer their application.
• D. Design and communicate a best practice that dictates designers only work within the confines of their own application.
