Appian ACD200 Exam Dumps

Correct Answer: C

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.

Correct Answer: BD

When building a process model that transforms a large data set, two things that should be ensured to include in the process model are an XOR gateway before the transformation node, to check for empty/null values, and a transformation

applied with an expression rule that takes the data set as an input, and loops through the dataset using a looping function, such as foreach. These things can help to improve the performance and reliability of the process model. The XOR

gateway can prevent unnecessary processing of empty or null data sets, which can save time and resources. The expression rule can perform the transformation in one transaction, instead of using multiple nodes or subprocesses, which can

reduce the memory footprint and the database load of the process model. Therefore, the correct answers are B and D.

Correct Answer: B

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]
