NEW QUESTION # 14
A lead designer receives this requirement:
Every time a record is modified, the data changed must be stored for audit.
Which design is the most efficient and has the least impact on the Appian application? (Choose the best answer.)
- A. Create a trigger on the database table to capture the audit trail to a table.
- B. Create an Appian process to capture the change history and write the audit trail to the database.
- C. Create a custom plugin that can write an audit trail to a log file.
- D. Create a web API call to an audit history system and write the audit trail to file.
Answer: A
Explanation:
Explanation
Creating a trigger on the database table to capture the audit trail to a table is the most efficient and has the least impact on the Appian application, because it avoids adding extra logic or calls to the Appian application, which could affect its performance and scalability. A trigger is a database object that automatically executes when a specified event occurs on a table or view. A trigger can be used to insert, update, or delete data from another table based on the changes made to the original table. References: [Triggers], [Audit Trail]
NEW QUESTION # 15
You are analyzing a poorly-performing process model.
You find that the process model in question has a lot of nodes and is mainly used to do background updates.
Which two things can be done to increase its performance? (Choose two.)
- A. Remove all activity chaining.
- B. Use swim lanes in the process model.
- C. Define the correct alerts for the process model.
- D. Refactor some nodes into subprocesses when possible.
Answer: A,D
Explanation:
Explanation
Two things that can be done to increase the performance of a poorly-performing process model that has a lot of nodes and is mainly used to do background updates are:
* Remove all activity chaining. Activity chaining is a feature that allows a process to move from one node to another without waiting for a commit point. This can improve the performance of some processes, but it can also cause memory issues and data inconsistency if used excessively or incorrectly. Removing activity chaining can reduce the memory consumption and ensure data integrity of the process model.
* Refactor some nodes into subprocesses when possible. Subprocesses are processes that are called from within another process model. Refactoring some nodes into subprocesses can simplify the main process model and improve its readability and maintainability. It can also reduce the memory usage and execution time of the main process model, as subprocesses are executed in parallel and have their own memory allocation.

NEW QUESTION # 16
You are investigating a slow-performing query entity which is mapped to a view and you decide to look in the data_store_details.csv log to gain more information. You see that the majority of the time is spent in the transform phase.
Which two actions can you take to reduce the time spent in the transform phase? (Choose two.)
- A. Reduce the number of columns returned from the query.
- B. Reduce the use of unnecessary columns in the GROUP BY clause in the database view.
- C. Lower the batch size parameter of the query.
- D. Create a database index on the column being filtered against.
Answer: A,C
Explanation:
Explanation
The data_store_details.csv log provides information about the performance of query entities. The log shows the time spent in three phases: extract, transform, and load. The extract phase is the time it takes to execute the SQL query on the database. The transform phase is the time it takes to convert the SQL result set into Appian data types. The load phase is the time it takes to return the data to the expression that invoked the query entity.
To reduce the time spent in the transform phase, two possible actions are to reduce the number of columns returned from the query and to lower the batch size parameter of the query. These actions can decrease the amount of data that needs to be converted and transferred, which can improve the performance of the query entity. Therefore, the correct answers are B and D.

Which XSD element is NOT supported within an Appian CDT? (Choose the best answer.)
- A. <xsd:complexType>
- B. <xsd:key>
- C. <xsd:annotation>
- D. <xsd:simpleContent>
Answer: B
Explanation:
Explanation
The xsd:key element is not supported within an Appian CDT. This element is used to define a key constraint for an element or a group of elements. Appian does not support key constraints in CDTs, as they are not relevant for data storage or manipulation. Instead, Appian uses primary keys and foreign keys to enforce uniqueness and referential integrity in CDTs. These keys are specified using the @Id and @JoinColumn JPA annotations, respectively. References: Supported XSD Elements and JPA Annotations

Your organization is in the process of redesigning its user interfaces in order to use space efficiently.
Which layout component is most appropriate for displaying the interface where the meaningful order of components is vertical?
- A. a!columnsLayout()
- B. a!sideBySideLayout()
- C. a!cardLayout()
- D. a!columnOverlay()
Answer: A
Explanation:
Explanation
The requirement is to use space efficiently in a user interface where the meaningful order of components is vertical. A columns layout is the most appropriate layout component for this requirement, as it allows you to arrange components into columns that stack vertically on smaller devices. A columns layout also provides options to control the width, alignment, and visibility of each column. The other options are not suitable for this requirement, as they either do not preserve the vertical order of components or do not use space efficiently. References:
* Columns Layout
