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 custom plugin that can write an audit trail to a log file.
- B. Create an Appian process to capture the change history and write the audit trail to the database.
- C. Create a web API call to an audit history system and write the audit trail to file.
- D. Create a trigger on the database table to capture the audit trail to a table.
Answer: D
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 # 44
Using a View, you pull a report on different employee transactions. You receive the following error:
"a!queryEntity: An error occurred while retrieving the data."
What is the most likely root cause? (Choose the best answer.)
- A. The rule contains a missing syntax.
- B. The view contains a large number of rows, requiring more time to fetch the data.
- C. The view doesn't have a column mapped as a Primary Key in its corresponding CDT.
- D. The required inputs were not provided.
Answer: B
Explanation:
Explanation
The most likely root cause of the error is that the view contains a large number of rows, requiring more time to fetch the data. This can result in a timeout or an out-of-memory error. To avoid this, you can use pagination or filters to limit the number of rows returned by the view. You can also optimize the view performance by using indexes, avoiding unnecessary joins, and reducing the number of columns. References: [Views], [View Performance]

NEW QUESTION # 47
You are required to test a Related Action that updates record data. You need to make sure that the correct users can access the form and that the data is updating successfully.
Which is the most appropriate testing method to achieve this using Appian?
- A. Performance Testing
- B. Load Testing
- C. Unit Testing
- D. User Interface (UI) Testing
Answer: C
Explanation:
Explanation
The most appropriate testing method to achieve this using Appian is Unit Testing. This is because unit testing allows you to test individual components of your application, such as forms, rules, or expressions, in isolation from other components or dependencies. Unit testing can help you verify that your Related Action works as expected for different users and data scenarios, as well as identify and fix any errors or bugs before deploying your application to production.

NEW QUESTION # 55
Your table contains several indexes.
Which two statements regarding indexes are correct? (Choose two.)
- A. Indexes decrease he performance of Read operations.
- B. Indexes increase the performance of Write operations.
- C. Indexes increase the performance of Read operations.
- D. Indexes decrease the performance of Write operations.
Answer: C,D
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 # 56

What should you use? (Choose the best answer.)
- A. Table
- B. Materialized view
- C. View
- D. Stored procedure
Answer: B
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 # 59
What should you use to create a virtual relation in a database to query the data?
- A. View
- B. Function
- C. Procedure
- D. Index
Answer: A
Explanation:
Explanation
The database object that should be used to create a virtual relation in a database to query the data is a view. A view is a searchable object that is defined by a query. It does not store any data but retrieves data from one or more tables at run time, creating a virtual table and returning the data in the defined format. It is created using joins, filters, aggregations, or other SQL operations. A view can be used to simplify complex queries, provide security, or enhance performance. Therefore, the correct answer is D.

According to Appian best practices, how should you define the environment name? (Choose the best answer.)
- A. Create an expression rule and update its value post-deployment.
- B. Create a constant and update its value post-deployment.
- C. Create a stored procedure.
- D. Create an environment-specific constant.
Answer: D
Explanation:
Explanation
According to Appian best practices, environment-specific constants should be used to define values that vary from one Appian environment to another. For example, if you want to generate an email body that contains the environment name, you can create a constant named ENVIRONMENT_NAME and assign it different values for DEV and TEST environments. This way, you can avoid hard-coding values in your expressions or rules, and simplify your deployment process by using automatic constant value mapping.
