You are using pie charts.
What is correct representation of Appian best practices? (Choose the best answer.)
- A. Pie charts should only be used to represent data that can be placed into identical categories.
- B. Use as many slices as possible.
- C. Try to use multiple pie charts when comparing multiple sets of data.
- D. Use pie charts to show proportional data.
Answer: D
Explanation:
Explanation
The correct representation of Appian best practices for using pie charts is to use pie charts to show proportional data. Pie charts are generally used to show how individual parts contribute to a whole, such as percentages or fractions. Pie charts should only be used to represent data that can be placed into distinct categories and should not consist of more than 6 slices. Pie charts should also include value and category labels for each slice, and sort the data values in ascending or descending order. References: Pie Chart Component, Charts UX Design Guide
NEW QUESTION # 14
You need to update the archival settings for a process model. You modified the automatic process clean-up settings and selected the archive processes option with 'n' days.
Which instances of that process model will be affected? (Choose the best answer.)
- A. Future and past instances of the process model including subprocesses.
- B. Future instances of the process model only including subprocesses.
- C. Future instances of the process model only.
- D. Future and past instances of the process model.

NEW QUESTION # 17
Your table contains several indexes.
Which two statements regarding indexes are correct? (Choose two.)
- A. Indexes increase the performance of Read operations.
- B. Indexes decrease the performance of Write operations.
- C. Indexes decrease he performance of Read operations.
- D. Indexes increase the performance of Write operations.
Answer: A,B
Explanation:
Explanation
An index is a data structure that allows for faster retrieval of data from a table based on one or more columns.
Indexes increase the performance of read operations, such as select queries, by reducing the number of records that need to be scanned. However, indexes decrease the performance of write operations, such as insert, update, and delete queries, by requiring additional work to maintain the index structure and ensure its consistency with the table data. Therefore, indexes should be used judiciously and only on columns that are frequently used in queries and have high selectivity (i.e., low number of duplicate values).
NEW QUESTION # 18
You are designing a case management application. The initiator creates a case, and the reviewer reviews it approximately 7 days later.
You have already designed a process model for the initiators to create the case.
Which process model design will result in the lowest memory impact? (Choose the best answer.)
- A. When all case details are entered, the case appears as a case record, and when the reviewer is ready to review the record, they can do so via a related action from the case record.
- B. When all case details are entered, the process flow will call a Sub-Process node to initialize a review process model for the reviewer.
- C. When all case details are entered, the process flow will call a Start Process node to initialize a review process model for the reviewer.
- D. When all case details are entered, the process flow will proceed and assign a task to the reviewer to review the record.
Answer: A
Explanation:
Explanation
The best process model design for a case management application is to use a case record and a related action.
This way, the process flow does not have to wait for the reviewer to complete the task, which can take up to 7 days. This reduces the memory impact of the process, as well as the risk of process timeouts or errors. The case record also provides a better user experience, as the reviewer can access the case details and the related action from one place. Therefore, the best answer is A.

NEW QUESTION # 19
There is a need to relate two entities in the data structure: Employee and Skill.
Employees can have multiple skills, and a single skill can relate to multiple employees.
What kind of relationship would these entities have, and what is the minimum number of tables required to implement the design, according to Appian best practices? (Choose the best answer.)
- A. One-to-many; 2 tables
- B. Many-to-many; 3 tables
- C. Many-to-one; 2 tables
- D. Many-to-many; 2 tables
Answer: B
Explanation:
Explanation
A many-to-many relationship is a type of relationship where multiple records in one table are associated with multiple records in another table. To implement a many-to-many relationship, a third table is needed to store the associations between the two entities. In this case, the third table would store the employee ID and the skill ID for each pair of employee and skill. This design allows for efficient querying and updating of the data, as well as avoiding data redundancy and inconsistency.
NEW QUESTION # 20
You need to show joined data from 5 tables. Each table contains a large number of rows and could generate a large result set after executing the Joins.

What should you use? (Choose the best answer.)
- A. Table
- B. Stored procedure
- C. Materialized view
- D. View
Answer: C
Explanation:
A materialised view is a physical table that holds the results of the SQL that a VIEW would normally be constructed from and can be generated periodically.
NEW QUESTION # 21
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 an expression rule and update it as per the business requirement.
- B. Create a stored procedure 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.

NEW QUESTION # 28
Which of the following is a sign that an application's performance is degrading and should be addressed with changes to the application design?
- A. The number of objects in the Application has increased from about 100 to about 500.
- B. Three of the top five most executed process models have a low completion percentage.
- C. Integration calls to an external system are consistently returning an HTTP status code of 500.
- D. The number of tasks assigned to users has increased from 1 per day to 5 per day.
Answer: B
Explanation:
Explanation
The question is about a sign that an application's performance is degrading and should be addressed with changes to the application design. The following is a sign of this:
* Three of the top five most executed process models have a low completion percentage. This means that a large proportion of the process instances are not reaching the end event, either because they are taking too long to complete, or because they are encountering errors or exceptions. This can affect the performance of the application, as it can consume more memory and resources, and reduce the availability and reliability of the application. You should review the process model design and identify the causes of the low completion rate, and make changes to improve the process efficiency and error handling.
The following are not signs of performance degradation that require changes to the application design:
* Integration calls to an external system are consistently returning an HTTP status code of 500. This means that the external system is experiencing an internal server error, which is not related to the application design. You should contact the external system provider and report the issue, or implement a fallback or retry mechanism in your integration logic.
* The number of tasks assigned to users has increased from 1 per day to 5 per day. This means that the workload or demand for the application has increased, which is not necessarily a sign of performance degradation. You should monitor the task completion rate and user feedback to see if the increase in tasks is affecting the user experience or satisfaction, and adjust the task assignment or prioritization logic if needed.
* The number of objects in the Application has increased from about 100 to about 500. This means that the application has grown in size and complexity, which is not necessarily a sign of performance degradation. You should follow the best practices for application design and maintenance, such as using folders, prefixes, dependencies, and documentation, to keep the application organized and manageable.
