NEW QUESTION # 24
When looking at the process model metrics for your application, you see that one of your process models has a low completion rate of 10%.
What are two potential causes of this? (Choose two.)
- A. A large value is configured for days until archival or deletion compared to other process models in your application.
- B. The process instances are long-lived compared to the configured days until archival or deletion.
- C. A large number of smart service nodes are configured in the process model.
- D. A large number of instances are encountering process errors, and they are not being addressed by the production support team.
Answer: B,D
Explanation:
Explanation
The question is about the potential causes of a low completion rate of 10% for a process model. The following are two possible causes of this:
* The process instances are long-lived compared to the configured days until archival or deletion. This means that the process instances take a long time to complete, and they are archived or deleted before they reach the end event. This reduces the completion rate, as only the instances that reach the end event are counted as completed.
* A large number of instances are encountering process errors, and they are not being addressed by the production support team. This means that the process instances are stuck in an error state, and they cannot proceed to the next step or the end event. This reduces the completion rate, as only the instances that reach the end event are counted as completed.
The following are not likely causes of a low completion rate:
* A large value is configured for days until archival or deletion compared to other process models in your application. This means that the process instances have more time to complete before they are archived or deleted. This should increase the completion rate, as more instances can reach the end event before they are removed from the system.
* A large number of smart service nodes are configured in the process model. This means that the process model has a complex logic or functionality that requires multiple smart services. This does not directly affect the completion rate, as long as the smart services execute successfully and do not cause errors or delays.

NEW QUESTION # 26
Your table contains several indexes.
Which two statements regarding indexes are correct? (Choose two.)
- A. Indexes increase the performance of Write operations.
- B. Indexes increase the performance of Read operations.
- C. Indexes decrease he performance of Read operations.
- D. Indexes decrease the performance of Write operations.
Answer: B,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 # 27

NEW QUESTION # 28
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.
- C. Future and past instances of the process model.
- D. Future instances of the process model only including subprocesses.
Answer: C
Explanation:
Explanation
By default, the process is automatically archived after 7 days. Setting one of these configurations to 0 as an interval will immediately archive or delete the instance after completion. Any changes made on this form are applied to all instances of the process model, including ones already completed. Subprocesses do not inherit this setting https://docs.appian.com/suite/help/22.4/process-model-object.html#data-management-tab
NEW QUESTION # 29
You are reviewing process model metrics and looking at AMUs to evaluate a process's memory usage.
Which statement is correct regarding this metric?
- A. AMUs is not a good measurement for process memory usage.
- B. Memory usage is considered low when it is below 10,000 AMUs.
- C. Memory usage is considered low when it is below 100,000 AMUs.
- D. Memory usage is considered low when it is below 1,000 AMUs.
Answer: C
Explanation:
Explanation
The question is about AMUs (Appian Memory Units), which is a metric that measures the memory usage of a process model. The following statement is correct regarding this metric:
* Memory usage is considered low when it is below 100,000 AMUs. This is based on the Appian recommendation that each process model should use less than 100,000 AMUs on average, as higher memory usage can affect the performance or stability of Appian.
The following statements are not correct regarding this metric:
* Memory usage is considered low when it is below 10,000 AMUs. This is too low, as most process models will use more than 10,000 AMUs on average, depending on their complexity and data size.
* Memory usage is considered low when it is below 1,000 AMUs. This is too low, as even simple process models will use more than 1,000 AMUs on average, depending on their configuration and parameters.
* AMUs is not a good measurement for process memory usage. This is not true, as AMUs is a standardized and consistent measurement that reflects the relative memory usage of different process models in Appian.

NEW QUESTION # 39
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. Use swim lanes in the process model.
- B. Define the correct alerts for the process model.
- C. Remove all activity chaining.
- D. Refactor some nodes into subprocesses when possible.
Answer: C,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.

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 a trigger on the database table to capture the audit trail to a table.
- C. Create an Appian process to capture the change history and write the audit trail to the database.
- D. Create a web API call to an audit history system and write the audit trail to file.
Answer: B
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]
