NEW QUESTION # 51
You are code-checking your colleague's process model before marking it as Ready for Deployment.
Which three best practices should be applied? (Choose three.)
- A. All XOR/OR gateways should have a single incoming ow.
- B. Activity chaining should be added to the majority of flows.
- C. Node inputs should not make the same query call more than once.
- D. All nodes should have exception flows
- E. All outgoing flows from a gateway should be labeled
Answer: A,C,E
Explanation:
Explanation
Three best practices that should be applied when code-checking a process model are:
* All XOR/OR gateways should have a single incoming flow. This is because XOR/OR gateways are used to split the process flow based on a condition or an event. Having multiple incoming flows to a gateway can cause confusion and ambiguity about the logic and order of execution. If multiple incoming flows are needed, they should be merged into a single flow using an AND gateway before reaching the XOR/OR gateway.
* All outgoing flows from a gateway should be labeled. This is because labels provide clarity and readability to the process model. They also help to document the business logic and rules that determine the path of execution. Labels should be concise, descriptive, and consistent throughout the process model.
* Node inputs should not make the same query call more than once. This is because repeated query calls can negatively impact the performance and efficiency of the process model. They can also cause data inconsistency and duplication if the query results change over time. Node inputs should use variables or rules to store and reuse query results whenever possible.

NEW QUESTION # 54
Which of the following is a sign that an application's performance is degrading and should be addressed with changes to the application design?
- A. Three of the top five most executed process models have a low completion percentage.
- B. The number of objects in the Application has increased from about 100 to about 500.
- C. The number of tasks assigned to users has increased from 1 per day to 5 per day.
- D. Integration calls to an external system are consistently returning an HTTP status code of 500.
Answer: A
Explanation:
Explanation
The question is about a sign that an application's performance is degrading and should be addressed with changes to the application design. The following is a sign of this:
* Three of the top five most executed process models have a low completion percentage. This means that a large proportion of the process instances are not reaching the end event, either because they are taking too long to complete, or because they are encountering errors or exceptions. This can affect the performance of the application, as it can consume more memory and resources, and reduce the availability and reliability of the application. You should review the process model design and identify the causes of the low completion rate, and make changes to improve the process efficiency and error handling.
The following are not signs of performance degradation that require changes to the application design:
* Integration calls to an external system are consistently returning an HTTP status code of 500. This means that the external system is experiencing an internal server error, which is not related to the application design. You should contact the external system provider and report the issue, or implement a fallback or retry mechanism in your integration logic.
* The number of tasks assigned to users has increased from 1 per day to 5 per day. This means that the workload or demand for the application has increased, which is not necessarily a sign of performance degradation. You should monitor the task completion rate and user feedback to see if the increase in tasks is affecting the user experience or satisfaction, and adjust the task assignment or prioritization logic if needed.
* The number of objects in the Application has increased from about 100 to about 500. This means that the application has grown in size and complexity, which is not necessarily a sign of performance degradation. You should follow the best practices for application design and maintenance, such as using folders, prefixes, dependencies, and documentation, to keep the application organized and manageable.

Answer: B,C,E
NEW QUESTION # 56
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 # 59
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 SSIS package to run at a regular interval.
- B. Create a view between both the [appian].[document] and [appian].[caseData] tables to feed the record.
- 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: B
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 # 60
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!columnOverlay()
- C. a!cardLayout()
- D. a!sideBySideLayout()
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
NEW QUESTION # 61

What should you do?
- A. Inspect the application server log.
- B. Observe the runtime of all test cases.
- C. Access the Rule Performance tab in the Administration Console.
- D. Use the Monitoring tab to find rules with a low completion percentage.
Answer: C
NEW QUESTION # 62
Which two practices are strongly discouraged for activity chaining? (Choose two.)
- A. More than 5 seconds between attended activities
- B. Less than or equal to 5 seconds between attended activities.
- C. Less than or equal to 50 node instances
- D. More than 50 node instances
Answer: A,D
Explanation:
Explanation
Activity chaining is a feature that allows users to complete multiple tasks in a row without returning to their task list. However, activity chaining can also have some drawbacks, such as increased memory consumption, longer transaction times, and reduced user feedback. Therefore, some practices are strongly discouraged for activity chaining, such as having more than 50 node instances or more than 5 seconds between attended activities. These practices can cause performance issues, user frustration, or process failures. Therefore, the correct answers are B and C.
