Appian ACD-301 Prüfungsfragen : Appian Certified Lead Developer

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

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. 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.
• B. Ensure that the application administrator group only has designers from that application's team.
• C. Create a best practice that enforces a peer review of the deletion of any components within the application.
• D. Design and communicate a best practice that dictates designers only work within the confines of their own application.

You are running an inspection as part of the first deployment process from TEST to PROD. You receive a notice that one of your objects will not deploy because it is dependent on an object from an application owned by a separate team.
What should be your next step?

• A. Check the dependencies of the necessary object. Deploy to PROD if there are few dependencies and it is low risk.
• B. Push a functionally viable package to PROD without the dependencies, and plan the rest of the deployment accordingly with the other team's constraints.
• C. Halt the production deployment and contact the other team for guidance on promoting the object to PROD.
• D. Create your own object with the same code base, replace the dependent object in the application, and deploy to PROD.

You are designing a process that is anticipated to be executed multiple times a day. This process retrieves data from an external system and then calls various utility processes as needed. The main process will not use the results of the utility processes, and there are no user forms anywhere.
Which design choice should be used to start the utility processes and minimize the load on the execution engines?

• A. Use the Start Process Smart Service to start the utility processes.
• B. Use Process Messaging to start the utility process.
• C. Start the utility processes via a subprocess asynchronously.
• D. Start the utility processes via a subprocess synchronously.

You have 5 applications on your Appian platform in Production. Users are now beginning to use multiple applications across the platform, and the client wants to ensure a consistent user experience across all applications.
You notice that some applications use rich text, some use section layouts, and others use box layouts. The result is that each application has a different color and size for the header.
What would you recommend to ensure consistency across the platform?

• A. In the common application, create a rule that can be used across the platform for section headers, and update each application to reference this new rule.
• B. In each individual application, create a rule that can be used for section headers, and update each application to reference its respective rule.
• C. In the common application, create one rule for each application, and update each application to reference its respective rule.
• D. Create constants for text size and color, and update each section to reference these values.
