• Question 11:

  Your organization is considering automating the running of expression rule test cases to provide unit tests for your Appian applications.

  Which three methods could be used to launch a test run when required? (Choose three.)

  A. Via the DevOps section of the Administration Console.
  B. A process model invoked via an API.
  C. A process model exposed to users as an action.
  D. A web hook from a content versioning system (CVS).
  E. A SAIL interface embedded in a report.
  B. A process model invoked via an API.
  C. A process model exposed to users as an action.
  E. A SAIL interface embedded in a report.

  ---

  Explanation/Reference:

  Three methods that could be used to launch a test run for expression rule test cases when required are: A process model invoked via an API. A process model can be designed to run test cases for expression rules using the a!testRule() function or the Test Rule smart service. This process model can be exposed as a web API with an HTTP method such as POST or PUT, allowing external systems or applications to invoke it through an HTTP request. A process model exposed to users as an action. A process model can also be designed to run test cases for expression rules using the same function or smart service as above. This process model can be exposed to users as an action on an interface, such as a button or a link, allowing users to trigger it manually when needed. A SAIL interface embedded in a report. A SAIL interface can be created to run test cases for expression rules using the a!testRule() function. This interface can be embedded in a report, such as a grid or a chart, allowing users to view the test results interactively on an interface.

• Question 12:

  Which user role should be used to allow external systems to invoke Appian web APIs?

  A. Service Account
  B. System Administrator
  C. Application User
  D. Designer
  A. Service Account

  ---

  Explanation/Reference:

  The question is about allowing external systems to invoke Appian web APIs. A service account is the user role that should be used for this purpose, as it is a special type of basic user that can be configured to authenticate with web APIs using an API key. A service account can also be assigned to specific groups or roles to control the access to web APIs. The other options are not user roles, but rather groups or user types that are not suitable for this purpose. References: Service Accounts Web API Security

• Question 13:

  The IT stakeholder wants to understand which processes have the highest footprint.

  What are the two places to get information on process model memory usage? (Choose two.)

  A. Administration Console
  B. Process monitoring tab
  C. Appian Health Check report
  D. Application server log file
  B. Process monitoring tab
  C. Appian Health Check report

  ---

  Explanation/Reference:

  Two places to get information on process model memory usage are: Process monitoring tab. The process monitoring tab is a feature in the Appian Designer that allows you to monitor and manage the performance and status of process models and instances. You can use the process monitoring tab to view various metrics and statistics about your processes, such as memory usage, execution time, node count, error count, etc. You can also filter, sort, and export the data for further analysis. The process monitoring tab can help you identify which processes have the highest memory footprint and potential performance issues. Appian Health Check report. The Appian Health Check report is a tool that provides insights into application design patterns and performance risks in your environment. The report covers four areas of your environment: design, user experience, infrastructure, and configuration. The report also includes graphs highlighting historical trends, such as user activity, average response times, and resource utilization. The Appian Health Check report can help you identify which processes have the highest memory consumption and suggestions for mitigating them.

• Question 14:

  Your organization requires a process to be initiated via an Appian web API.

  Which HTTP request methods should the API use?

  A. HEAD
  B. GET
  C. POST
  D. CONNECT
  C. POST

  ---

  Explanation/Reference:

  The question is about initiating a process via an Appian web API. The HTTP request method that the API should use is POST, as it is the method that allows sending data to the server and creating or updating a resource. In this case, the data would be the process parameters and the resource would be the process instance. The other options are not suitable for this purpose, as they either do not allow sending data or do not create or update a resource. References: HTTP Request Methods Start Process Web API

• Question 15:

  You create an interface, but it fails to load. When you open the design errors log, you see a memory circuit breaker error.

  What are two possible root causes of this error? (Choose two.)

  A. A database query is taking too long to evaluate.
  B. The interface contains some special characters.
  C. The interface is storing too much data in local variables.
  D. The interface component is looping over too many items.
  C. The interface is storing too much data in local variables.
  D. The interface component is looping over too many items.

  ---

  Explanation/Reference:

  A memory circuit breaker error occurs when an interface consumes too much memory on the server. This can happen when the interface is storing too much data in local variables or when the interface component is looping over too many items. Both of these scenarios can cause excessive memory allocation and garbage collection, which can degrade the performance of the interface and the server. Therefore, the possible root causes of this error are C and D. References: Memory Circuit Breaker Performance Best Practices

• Question 16:

  You want to display a Gender dropdown, and its choice label may change in the future as per the business requirement.

  Given transactional database tables rely on this data for reporting, what is the most appropriate action? (Choose the best answer.)

  A. Create a constant and update it as per the business requirement.
  B. Create a stored procedure and update it as per the business requirement.
  C. Create an expression rule and update it as per the business requirement.
  D. Create these entries in a table and reference them through a query entity rule as per the business requirement.
  D. Create these entries in a table and reference them through a query entity rule as per the business requirement.

  ---

  Explanation/Reference:

  The most appropriate action to display a Gender dropdown whose choice label may change in the future as per the business requirement is to create these entries in a table and reference them through a query entity rule as per the business requirement. This is because storing the choice labels in a table allows for easy maintenance and modification of the data without affecting the transactional database tables that rely on this data for reporting. Using a query entity rule allows for retrieving the data from the table and populating the dropdown component dynamically and consistently across different interfaces or processes that use this data.

• Question 17:

  You are required to display information for pending tasks for each individual in an application. There will be tasks for a single specific application.

  Which context type should you choose for the Task Report Type?

  A. Tasks by process model
  B. Tasks attributed to user
  C. Tasks by process
  D. Tasks assigned to a group
  B. Tasks attributed to user

  ---

  Explanation/Reference:

  The context type that should be chosen for the Task Report Type is Tasks attributed to user. This is because this context type allows you to display information for pending tasks for each individual in an application. You can filter the tasks by application name, process model name, or task name. This context type also supports drilldown functionality, which enables users to view more details about a specific task or complete it directly from the report. References: Task Report Types

• Question 18:

  You are creating the group structure of a new application.

  Which three best practices apply? (Choose three.)

  A. Avoid creating custom group types unless there is a strong need/requirement.
  B. Only create the groups necessary for task assignment or security.
  C. Flat group structures should be avoided.
  D. Group names should not include the application prefix.
  E. Keep group names unique.
  A. Avoid creating custom group types unless there is a strong need/requirement.
  B. Only create the groups necessary for task assignment or security.
  E. Keep group names unique.

• Question 20:

  When looking at the process model metrics for your application, you see that one of your process models has a low completion rate of 10%.

  What are two potential causes of this? (Choose two.)

  A. The process instances are long-lived compared to the configured days until archival or deletion.
  B. A large number of instances are encountering process errors, and they are not being addressed by the production support team.
  C. A large value is configured for days until archival or deletion compared to other process models in your application.
  D. A large number of smart service nodes are configured in the process model.
  A. The process instances are long-lived compared to the configured days until archival or deletion.
  B. A large number of instances are encountering process errors, and they are not being addressed by the production support team.

  ---

  Explanation/Reference:

  The question is about the potential causes of a low completion rate of 10% for a process model. The following are two possible causes of this:

  The process instances are long-lived compared to the configured days until archival or deletion. This means that the process instances take a long time to complete, and they are archived or deleted before they reach the end event. This

  reduces the completion rate, as only the instances that reach the end event are counted as completed.

  A large number of instances are encountering process errors, and they are not being addressed by the production support team. This means that the process instances are stuck in an error state, and they cannot proceed to the next step or

  the end event. This reduces the completion rate, as only the instances that reach the end event are counted as completed.

  The following are not likely causes of a low completion rate:

  A large value is configured for days until archival or deletion compared to other process models in your application. This means that the process instances have more time to complete before they are archived or deleted. This should increase

  the completion rate, as more instances can reach the end event before they are removed from the system.

  A large number of smart service nodes are configured in the process model. This means that the process model has a complex logic or functionality that requires multiple smart services. This does not directly affect the completion rate, as

  long as the smart services execute successfully and do not cause errors or delays.
