NEW QUESTION # 20
You have been asked to produce a Tempo report, with the following requirements:
The report should display in Appian.
The data is held in a business database, but performance in Appian is a key requirement.
Which three actions can you take to minimize the performance impact of your report? (Choose three.)
- A. Limit the number of series values and categories in the report.
- B. Use the query process analytics function to retrieve the data.
- C. Display the report as a task report on the Tasks tab.
- D. Use local variables in your report interface to avoid redundant database queries.
- E. Perform aggregation in the database using a view prior to reading the data into Appian.
Answer: A,D,E
Explanation:
Explanation
The three actions that can be taken to minimize the performance impact of the Tempo report are:
* Limit the number of series values and categories in the report. This is because having too many series values and categories can make the report difficult to read and render, as well as increase the amount of data that needs to be transferred from the database to Appian. A good practice is to limit the number of series values to 10 or less, and the number of categories to 20 or less.
* Use local variables in your report interface to avoid redundant database queries. This is because local variables can store the results of database queries and reuse them in multiple places within the interface, reducing the number of times the database is accessed. A good practice is to use local variables for common filters, aggregations, or calculations that are used in multiple charts or grids.
* Perform aggregation in the database using a view prior to reading the data into Appian. This is because performing aggregation in the database can reduce the amount of data that needs to be transferred from the database to Appian, as well as leverage the database's optimization capabilities. A good practice is to create a view in the database that performs the aggregation and then query that view using Appian. References: Report Performance Best Practices

NEW QUESTION # 22
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. Administration Console
- C. Application server log file
- D. Appian Health Check report
Answer: A,D
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.

You are presenting data through data visualization.
Match the chart types to the data they are best suited to represent. Each answer will be used once.
Note: To change your responses, you may deselect your response by clicking the blank space at the top of the selection list.
Answer:
Explanation:
Explanation
The question is about presenting data through data visualization and matching the chart types to the data they are best suited to represent. The following are the correct matches:
* A pie chart is best suited to represent proportional data in one category and can help us understand the contribution of parts to a whole. A pie chart shows the relative size of each part as a slice of a circular pie, and can display percentages or absolute values. For example, a pie chart can show the market share of different smartphone brands in one country.
* A line chart is best suited to represent direct comparison of data with multiple categories with a relatively small set of positive and negative values. A line chart shows the change or trend of data over time or another variable, and can display multiple lines for different categories. For example, a line chart can show the temperature change of different cities over a year.
* A bar chart is best suited to represent values across a relatively large number of categories that are not sequential or time-based. A bar chart shows the magnitude or frequency of data using horizontal or vertical bars, and can display multiple bars for different categories. For example, a bar chart can show the number of students enrolled in different courses in a university.

NEW QUESTION # 27
You are creating an ERD that models the data for a college and includes a Many-to-Many relationship, Student-to-Class, where a student can be enrolled in multiple classes, and a class can enroll multiple students.
How can you handle this relationship so that it can be supported in Appian and remain in at least First Normal Form? (Choose the best answer.)
- A. It cannot be done, because Appian CDTs cannot handle Many-to Many relationships.
- B. The Class table should have a Student field to hold an array of Student IDs.
- C. The Student table should have a Class field to hold an array of Class IDs.
- D. A joining table can be used to hold instances of Student/Class relationships.
Answer: D
Explanation:
Explanation
A joining table can be used to hold instances of Student/Class relationships, so that it can be supported in Appian and remain in at least First Normal Form. A joining table is a table that contains only foreign keys that reference the primary keys of other tables. A joining table can be used to model a Many-to-Many relationship between two entities, such as Student and Class. For example, a joining table called Enrollment could have two columns: Student_ID and Class_ID, which reference the primary keys of the Student and Class tables respectively. Each row in the Enrollment table represents an instance of a student enrolled in a class. References: [Joining Tables], [Many-to-Many Relationships], [First Normal Form]

NEW QUESTION # 32
You are about to deploy a package to another environment.
Which two statements are true? (Choose two.)
- A. It is not possible to undo changes from an import to all types of objects.
- B. It is possible to import the same package multiple times.
- C. It is possible to undo changes from an import to all types of objects.
- D. It is not possible to import the same package multiple times.
Answer: A,B
Explanation:
Explanation
Two true statements are:
* It is not possible to undo changes from an import to all types of objects. Once a package is imported to an environment, it applies changes to the existing objects or creates new objects based on the package contents. There is no built-in mechanism to revert these changes or delete these objects automatically.
Therefore, it is important to test the package in a non-production environment before importing it to production, and to backup any objects that may be overwritten by the import.
* It is possible to import the same package multiple times. A package can be imported to an environment more than once, as long as it does not contain any conflicts or errors that would prevent the import.
However, importing the same package multiple times may not have any effect if there are no changes in the package contents or in the target environment since the last import. References: Prepare Deployment Packages, Application Deployment Guidelines

NEW QUESTION # 36
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 web hook from a content versioning system (CVS).
- B. Via the DevOps section of the Administration Console.
- C. A process model exposed to users as an action.
- D. A process model invoked via an API.
- E. A SAIL interface embedded in a report.
Answer: C,D,E
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.

NEW QUESTION # 37
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 stored procedure and update it as per the business requirement.
- B. Create an expression rule and update it as per the business requirement.
- C. Create a constant 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.
Answer: D
Explanation:
Explanation
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.
