NEW QUESTION # 37
You are tasked with configuring a process model to store the result of an expression rule for every item in a list.
Which process model design has the lowest memory footprint?
- A. Run MNI over a script task for each item in the list.
- B. Call a sub-process for each item in the list.
- C. Configure a script task to use a!foreach to iterate over each item in the list.
- D. Create a loop of smart service nodes in the process model and execute it for each item in the list.
Answer: C
Explanation:
Explanation
The question is about designing a process model to store the result of an expression rule for every item in a list with the lowest memory footprint. The best design for this purpose is to configure a script task to use a!foreach to iterate over each item in the list, as it allows you to execute an expression rule for each element of an array without creating multiple nodes or subprocesses in the process model. A script task is a node that executes an expression without user interaction, and a!foreach is a function that applies an expression to each element of an array and returns an array of results. The other options are not optimal for this purpose, as they either create more nodes or subprocesses in the process model, which consume more memory and resources.

NEW QUESTION # 39
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 required inputs were not provided.
- D. The view doesn't have a column mapped as a Primary Key in its corresponding CDT.
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 # 40
You are troubleshooting a process model instance with an error in a node.
Which two options will allow you to obtain more information about the error? (Choose two.)
- A. View the process model properties.
- B. Open the process model from the process instance.
- C. View the properties dialog of the affected node.
- D. View the Process Details dialog.
Answer: C,D
Explanation:
Explanation
When troubleshooting a process model instance with an error in a node, two options that can provide more information about the error are to view the Process Details dialog and to view the properties dialog of the affected node. The Process Details dialog shows the status, history, and variables of the process instance, as well as any errors or warnings that occurred during the execution. The properties dialog of the affected node shows the configuration, inputs, outputs, and expressions of the node, as well as any errors or warnings that occurred during the evaluation. These options can help to identify the cause and location of the error, and to apply any necessary fixes. Therefore, the correct answers are B and D.

NEW QUESTION # 41
An organization has decided to integrate with a third-party to scan incoming documents and capture the details in a table called [appian].[document]. Each document will form a new case in Appian to be displayed on a Record List.
The record needs to show data from both [appian].[document] and [appian].[caseData], which holds additional case information.
What is the most efficient way to achieve this?
- A. Create a view between both the [appian].[document] and [appian].[caseData] tables to feed the record.
- B. Create a SSIS package to run at a regular interval.
- C. Create a trigger on the [appian].[document] table to copy all the data across to the [appian].[caseData] table and point the record at [appian].[caseData].
- D. Create a stored procedure to query the data from both the [appian].[document] and [appian].[caseData] tables.
Answer: A
Explanation:
Explanation
The most efficient way to achieve the integration between the third-party document scanner and the Appian record list is to create a view between both the [appian].[document] and [appian].[caseData] tables to feed the record. A view is a virtual table that is defined by a query and does not store any data. It can join, filter, aggregate, or transform data from one or more tables and present it in a desired format. A view can be used to simplify complex queries, provide security, or enhance performance. By creating a view, the record can show data from both tables without duplicating or copying any data. Therefore, the correct answer is C.

NEW QUESTION # 44
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. A large number of instances are encountering process errors, and they are not being addressed by the production support team.
- C. The process instances are long-lived compared to the configured days until archival or deletion.
- D. A large number of smart service nodes are configured in the process model.
Answer: B,C
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 # 47
You have been asked to produce a Tempo report, with the following requirements:
The report should display in Appian.
The data is held in a business database, but performance in Appian is a key requirement.
Which three actions can you take to minimize the performance impact of your report? (Choose three.)
- A. Perform aggregation in the database using a view prior to reading the data into Appian.
- B. Limit the number of series values and categories in the report.
- C. Display the report as a task report on the Tasks tab.
- D. Use the query process analytics function to retrieve the data.
- E. Use local variables in your report interface to avoid redundant database queries.
Answer: A,B,E
Explanation:
Explanation
The three actions that can be taken to minimize the performance impact of the Tempo report are:
* Limit the number of series values and categories in the report. This is because having too many series values and categories can make the report difficult to read and render, as well as increase the amount of data that needs to be transferred from the database to Appian. A good practice is to limit the number of series values to 10 or less, and the number of categories to 20 or less.
* Use local variables in your report interface to avoid redundant database queries. This is because local variables can store the results of database queries and reuse them in multiple places within the interface, reducing the number of times the database is accessed. A good practice is to use local variables for common filters, aggregations, or calculations that are used in multiple charts or grids.
* Perform aggregation in the database using a view prior to reading the data into Appian. This is because performing aggregation in the database can reduce the amount of data that needs to be transferred from the database to Appian, as well as leverage the database's optimization capabilities. A good practice is to create a view in the database that performs the aggregation and then query that view using Appian. References: Report Performance Best Practices

Which performance log should you look at to see the mean evaluation time of this rule every hour?
- A. expressions_metrics.csv
- B. expressions_trace.csv
- C. expressions_details.csv
- D. expressions_summary.csv
Answer: C
Explanation:
Explanation
The performance log that should be used to see the mean evaluation time of a slow-performing expression rule every hour is expressions_details.csv. This log records information about how expression rules are performing in the system, such as the number of evaluations, the total time, the mean total time, and the standard deviation of the total time. The log is written to once every hour, and it provides fine-grain aggregation by type of expression rule. The mean total time column shows the average time it took to evaluate an expression rule in milliseconds. Therefore, the correct answer is A.
