1. You are reviewing the Engine Performance Logs in Production for a single application that has been live for six months. This application experiences concurrent user activity and has a fairly sustained load during business hours. The client has reported performance issues with the application during business hours.

During your investigation, you notice a high Work Queue - Java Work Queue Size value in the logs. You also notice unattended process activities, including timer events and sending notification emails, are taking far longer to execute than normal.

The client increased the number of CPU cores prior to the application going live.

What is the next recommendation?

A. Add more engine replicas.

B. Optimize slow-performing user interfaces.

C. Add more application servers.

D. Add execution and analytics shards

2. You are developing a case management application to manage support cases for a large set of sites. One of the tabs in this application s site Is a record grid of cases, along with Information about the site corresponding to that case. Users must be able to filter cases by priority level and status.

You decide to create a view as the source of your entity-backed record, which joins the separate case/site tables (as depicted in the following Image).

Which three column should be indexed?

3. 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. Create your own object with the same code base, replace the dependent object in the application, and deploy to PROD.

B. Halt the production deployment and contact the other team for guidance on promoting the object to PROD.

C. Check the dependencies of the necessary object. Deploy to PROD if there are few dependencies and it is low risk.

D. Push a functionally viable package to PROD without the dependencies, and plan the rest of the deployment accordingly with the other team’s constraints.

4. You need to design a complex Appian integration to call a RESTful API. The RESTful API will be used to update a case in a customer’s legacy system.

What are three prerequisites for designing the integration?

A. Define the HTTP method that the integration will use.

B. Understand the content of the expected body, including each field type and their limits.

C. Understand whether this integration will be used in an interface or in a process model.

D. Understand the different error codes managed by the API and the process of error handling in Appian.

E. Understand the business rules to be applied to ensure the business logic of the data.

6. 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. Create constants for text size and color, and update each section to reference these values.

B. 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.

C. In the common application, create one rule for each application, and update each application to reference its respective rule.

D. In each individual application, create a rule that can be used for section headers, and update each application to reference its respective rule.

7. You are tasked to build a large-scale acquisition application for a prominent customer. The acquisition process tracks the time it takes to fulfill a purchase request with an award.

The customer has structured the contract so that there are multiple application development teams.

How should you design for multiple processes and forms, while minimizing repeated code?

8. HOTSPOT

For each scenario outlined, match the best tool to use to meet expectations. Each tool will be used once Note: To change your responses, you may deselected your response by clicking the blank space at the top of the selection list.

9. You are required to create an integration from your Appian Cloud instance to an application hosted within a customer’s self-managed environment.

The customer’s IT team has provided you with a REST API endpoint to test with:

https://internal.network/api/api/ping.

Which recommendation should you make to progress this integration?

A. Expose the API as a SOAP-based web service.

B. Deploy the API/service into Appian Cloud.

C. Add Appian Cloud’s IP address ranges to the customer network’s allowed IP listing.

D. Set up a VPN tunnel.

10. You have an active development team (Team A) building enhancements for an application (App X) and are currently using the TEST environment for User Acceptance Testing (UAT).

A separate operations team (Team B) discovers a critical error in the Production instance of App X that they must remediate. However, Team B does not have a hotfix stream for which to accomplish this. The available environments are DEV, TEST, and PROD.

Which risk mitigation effort should both teams employ to ensure Team A’s capital project is only minorly interrupted, and Team B’s critical fix can be completed and deployed quickly to end users?

A. Team B must communicate to Team A which component will be addressed in the hotfix to avoid overlap of changes. If overlap exists, the component must be versioned to its PROD state before being remediated and deployed, and then versioned back to its latest development state. If overlap does not exist, the component may be remediated and deployed without any version changes.

B. Team A must analyze their current codebase in DEV to merge the hotfix changes into their latest enhancements. Team B is then required to wait for the hotfix to follow regular deployment protocols from DEV to the PROD environment.

C. Team B must address changes in the TEST environment. These changes can then be tested and deployed directly to PROD. Once the deployment is complete, Team B can then communicate their changes to Team A to ensure they are incorporated as part of the next release.

D. Team B must address the changes directly in PROD. As there is no hotfix stream, and DEV and TEST are being utilized for active development, it is best to avoid a conflict of components. Once Team A has completed their enhancements work, Team B can update DEV and TEST accordingly.

11. As part of an upcoming release of an application, a new nullable field is added to a table that contains customer data. 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?

12. You are the lead developer for an Appian project, in a backlog refinement meeting. You are presented with the following user story:

“As a restaurant customer, I need to be able to place my food order online to avoid waiting in line for takeout.”

Which two functional acceptance criteria would you consider ‘good’?

A. The user will click Save, and the order information will be saved in the ORDER table and have audit history.

B. The user will receive an email notification when their order is completed.

C. The system must handle up to 500 unique orders per day.

D. The user cannot submit the form without filling out all required fields.

13. 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. Start the utility processes via a subprocess synchronously.

C. Use Process Messaging to start the utility process.

D. Start the utility processes via a subprocess asynchronously.

14. 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 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.

B. 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.

C. 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.

D. In the Administration Console, configure the third-party database as a “New Data Source.” Then, use a!queryEntity to retrieve the data.

15. Users must be able to navigate throughout the application while maintaining complete visibility in the application structure and easily navigate to previous locations.

Which Appian Interface Pattern would you recommend?
