ACD300 Practice Questions

Question # 1
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. Deluding 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 handing m Appall
E. Understand the business rules to be applied to ensure the business logic of the data


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

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

D. Understand the different error codes managed by the API and the process of error handing m Appall

Explanation:

To design a complex Appian integration to call a RESTful API, you need to have some prerequisites, such as:

Define the HTTP method that the integration will use. The HTTP method is the action that the integration will perform on the API, such as GET, POST, PUT, PATCH, or DELETE. The HTTP method determines how the data will be sent and received by the API, and what kind of response will be expected.

Understand the content of the expected body, including each field type and their limits. The body is the data that the integration will send to the API, or receive from the API, depending on the HTTP method. The body can be in different formats, such as JSON, XML, or form data. You need to understand how to structure the body according to the API specification, and what kind of data types and values are allowed for each field.

Understand the different error codes managed by the API and the process of error handling in Appian. The error codes are the status codes that indicate whether the API request was successful or not, and what kind of problem occurred if not. The error codes can range from 200 (OK) to 500 (Internal Server Error), and each code has a different meaning and implication. You need to understand how to handle different error codes in Appian, and how to display meaningful messages to the user or log them for debugging purposes.

The other two options are not prerequisites for designing the integration, but rather considerations for implementing it.

Understand whether this integration will be used in an interface or in a process model. This is not a prerequisite, but rather a decision that you need to make based on your application requirements and design. You can use an integration either in an interface or in a process model, depending on where you need to call the API and how you want to handle the response. For example, if you need to update a case in real-time based on user input, you may want to use an integration in an interface. If you need to update a case periodically based on a schedule or an event, you may want to use an integration in a process model.

Understand the business rules to be applied to ensure the business logic of the data. This is not a prerequisite, but rather a part of your application logic that you need to implement after designing the integration. You need to apply business rules to validate, transform, or enrich the data that you send or receive from the API, according to your business requirements and logic. For example, you may need to check if the case status is valid before updating it in the legacy system, or you may need to add some additional information to the case data before displaying it in Appian.



Question # 2
You have created a Web API in Appian. with the following URL to call it: https://exampleappiancloud.com/suite/webapi/usef_managefnent/ users ?username=)=john.smith. Which is the connect syntax forreferring to the user name parameter'
A. httpirequest.queryParameters users username
B. httpirequest usees username
C. httpirequest formData username
D. httpirequest queryParameters.username


D. httpirequest queryParameters.username

Explanation:

The correct syntax for referring to the username parameter in the Web API URL is httpirequest.queryParameters.username. This syntax allows you to access the value of the username parameter that is passed in the query string of the URL after the question mark (?). For example, if the URL ishttps://exampleappiancloud.com/suite/webapi/user_management/users?username=john.smith, then httpirequest.queryParameters.username will return john.smith. Verified References: Appian Documentation, section “Web API”.



Question # 3
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 mam 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 lo star! the utility process.
D. Start the utility processes via a subprocess asynchronously


C. Use Process Messaging lo star! the utility process.

Explanation:

To design a process that is anticipated to be executed multiple times a day, that retrieves data from an external system and then calls various utility processes as needed, you should use Process Messaging to start the utility process and minimize the load on the execution engines. Process Messaging is a feature that allows you to send and receive messages between processes in Appian. By using Process Messaging, you can start the utility process asynchronously, which means that the main process does not have to wait for the utility process to finish before continuing. This way, you can improve the performance and scalability of your process design, and reduce the load on the execution engines.

The other options are not as effective. Option A, using the Start Process Smart Service to start the utility processes, would also start the utility process asynchronously, but it would require more configuration and maintenance than Process Messaging. Option B, starting the utility processes via a subprocess synchronously, would start the utility process as a part of the main process flow, which means that the main process would have to wait for the utility process to finish before continuing. This would reduce the performance and scalability of your process design, and increase the load on the execution engines. Option D, starting the utility processes via a subprocess asynchronously, would also start the utility process as a part of the main process flow,but it would not wait for the utility process to finish before continuing. However, this option would still create more overhead than Process Messaging, as it would create more instances of processes in Appian.



Question # 4
During a sprint planning session, you are reviewing a user story that reads: “As a customer, I need to be able to track the status of my order in real-time." What two functional acceptance criteria would be considered 'good' for this feature?
A. The system will show the order status in a user-friendly dashboard.
B. The user must manually refresh the page to see the updated status.
C. The system will send a push notification each time the order status changes.
D. The user will see a progress bar indicating the status of their order.
E. The system must be able to handle up to 1000 simultaneous users querying their order status at once.


A. The system will show the order status in a user-friendly dashboard.
D. The user will see a progress bar indicating the status of their order.



Question # 5
You have an active development team (Team A) building enhancements for an application (App X'). and ate currently using the TEST environment for UAT.

A separate operations team ('Team B) discovers a critical error in the Production instance of App X that they must remediate However. Team 6 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 AS capital project is only minorly interrupted, and Team B s critical fix can be completed and deployed quickly to end users?
A. Team 8 must communicate to Team A which component will be addressed in the hotfix to avoid overlap of changes It 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 OEV lo merge the hotfix changes into their latest enhancements. Team B is then requited to wait for the hotfix to follow regular deployment protocols from DEV to the PROO environment.
C. Team 8 must address changes in the TEST environment These changes can then be tested and deployed directly to PRO
D. Once the deployment is complete. Team B can then communicate their changes to Teams to ensure they are Incorporated as a part of the next release.
E. Team 8 must address the changes directly in PRO


A. Team 8 must communicate to Team A which component will be addressed in the hotfix to avoid overlap of changes It 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



Question # 6
You are asked to design a case management system for a client in addition to storing some basic metadata about a case, one of the client s requirements Is the ability for users to update a case The client would like any user in their organization of 500 people to be able to make these updates The users are all based in the company's headquarters, and there will be frequent cases where users are attempting to edit the same case. The client wants to ensure no information Is lost when these edits occur and does not want the solution to burden their process administrators with any additional effort.
Which data locking approach should you recommend?
A. Allow edits without locking the case GDI
B. Use the database lo implement tow lewd pessimistic locking.
C. Add an ©Version annotation to the case COT to manage Vie locking
D. Design a process report and query to determine who opened the edit form first


C. Add an ©Version annotation to the case COT to manage Vie locking



Question # 7
Your Agile Scrum project requires you to manage two teams, with three developers per team. Both teams are to work on the same application In parallel. How should the work be divided between the teams, avoiding issues caused by cross-dependency?
A. Group epics and stones by technical difficulty, and allocate one team the more challenging stories
B. Group epics and stones by feature, and allocate work between each team by feature.
C. Allocate stories to each team based on the cumulative years of experience of the team members.
D. Have each team choose the stones they would like to work on based on personal preference


B. Group epics and stones by feature, and allocate work between each team by feature.

Explanation:

The best way to divide the work between the teams, avoiding issues caused by cross-dependency, is to group epics and stories by feature, and allocate work between each team by feature. This way, each team can focus on a specific feature and minimize the need for coordination or integration with the other team. This also reduces the risk of conflicts or errors when merging the code from both teams.
