NEW QUESTION # 37
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. The interface component is looping over too many items.
- B. The interface is storing too much data in local variables.
- C. The interface contains some special characters.
- D. A database query is taking too long to evaluate.
Answer: A,B
Explanation:
Explanation
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.

An organization has decided to integrate with a third-party to scan incoming documents and capture the details in a table called [appian].[document]. Each document will form a new case in Appian to be displayed on a Record List.
The record needs to show data from both [appian].[document] and [appian].[caseData], which holds additional case information.

- A. Create a trigger on the [appian].[document] table to copy all the data across to the [appian].[caseData] table and point the record at [appian].[caseData].
- B. Create a view between both the [appian].[document] and [appian].[caseData] tables to feed the record.
- C. Create a SSIS package to run at a regular interval.
- D. Create a stored procedure to query the data from both the [appian].[document] and [appian].[caseData] tables.
Answer: B

You need to build a QC review process for a factory that allows a technician to review each production line on a regular basis.
A QC technician has 30 minutes to complete their review, after which time the review will expire and be marked as a "missed review." If this, occurs, a supervisor should be notified via email and the review data should not be saved. Additional requirements are as follows:
The user should be able to save a draft of their review before submission, and come back to work on it later.
Once submitted, the review data should be saved to the database.
Which option needs to be implemented to meet the requirements?

NEW QUESTION # 43
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. Process monitoring tab
- B. Appian Health Check report
- C. Application server log file
- D. Administration Console
Answer: A,B
Explanation:
Explanation
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.

NEW QUESTION # 44
Which two statements about the a!queryEntity() function are true? (Choose two.)
- A. Setting the fetchTotalCount parameter to False can improve the performance of the rule.
- B. The queries defined using the query parameter return a constrained subset of matching data records by default.
- C. The entity value must be given as a constant of type Data Store Entity.
- D. The queries defined using the query parameter are not limited in how long they wait to return results.
Answer: A,C
Explanation:
Explanation
The two statements about the a!queryEntity() function that are true are:
* The entity value must be given as a constant of type Data Store Entity. This is because the entity value specifies which data store entity (table or view) to query from. The value must be a constant that references an existing data store entity in Appian Designer. You cannot use a variable or an expression for this value.
* Setting the fetchTotalCount parameter to False can improve the performance of the rule. This is because setting this parameter to False tells Appian not to calculate the total number of records that match the query criteria, which can be an expensive operation for large data sets. By default, this parameter is set to True, which means Appian will return the total count along with the query results.

- B. Define the correct alerts for the process model.
- C. Use swim lanes in the process model.

NEW QUESTION # 52
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. A process model invoked via an API.
- B. A process model exposed to users as an action.
- C. A SAIL interface embedded in a report.
- D. A web hook from a content versioning system (CVS).
- E. Via the DevOps section of the Administration Console.
Answer: A,B,C
Explanation:
Explanation
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.
