NEW QUESTION # 11
What is the lowest permission required on the data store in order to query, write, and delete data?
- A. Editor
- B. Manager
- C. Administrator
- D. Viewer
Answer: D
Explanation:
Explanation
The lowest permission required on the data store in order to query, write, and delete data is Viewer. This is because the data store permissions only control the ability to view and modify the data store object in Appian Designer, not the actual data in the database. To query, write, and delete data, the user needs to have the appropriate SQL permissions on the database tables or views that are mapped to the data store entities. References: Data Store Permissions
NEW QUESTION # 12
You are designing a case management application. The initiator creates a case, and the reviewer reviews it approximately 7 days later.
You have already designed a process model for the initiators to create the case.
Which process model design will result in the lowest memory impact? (Choose the best answer.)
- A. When all case details are entered, the process flow will proceed and assign a task to the reviewer to review the record.
- B. When all case details are entered, the case appears as a case record, and when the reviewer is ready to review the record, they can do so via a related action from the case record.
- C. When all case details are entered, the process flow will call a Start Process node to initialize a review process model for the reviewer.
- D. When all case details are entered, the process flow will call a Sub-Process node to initialize a review process model for the reviewer.
Answer: B
Explanation:
Explanation
The best process model design for a case management application is to use a case record and a related action.
This way, the process flow does not have to wait for the reviewer to complete the task, which can take up to 7 days. This reduces the memory impact of the process, as well as the risk of process timeouts or errors. The case record also provides a better user experience, as the reviewer can access the case details and the related action from one place. Therefore, the best answer is A.

NEW QUESTION # 13
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 stored procedure to query the data from both the [appian].[document] and [appian].[caseData] tables.
- B. 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].
- C. Create a view between both the [appian].[document] and [appian].[caseData] tables to feed the record.
- D. Create a SSIS package to run at a regular interval.
Answer: C
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 # 14
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. Call a sub-process for each item in the list.
- B. Configure a script task to use a!foreach to iterate over each item in the list.
- C. Create a loop of smart service nodes in the process model and execute it for each item in the list.
- D. Run MNI over a script task for each item in the list.
Answer: B
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.

* Script Task
* a!foreach()

NEW QUESTION # 17
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. User Interface (UI) Testing
- C. Load Testing
- D. Unit Testing
Answer: D
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 # 20
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 instances of the process model only.
- B. Future and past instances of the process model including subprocesses.
- C. Future instances of the process model only including subprocesses.
- D. Future and past instances of the process model.
Answer: D
Explanation:
Explanation
The instances of the process model that will be affected by modifying the automatic process clean-up settings are future and past instances of the process model. The automatic process clean-up settings allow you to specify how long completed or canceled processes should be kept before being archived or deleted. These settings apply to all instances of the process model, regardless of when they were started or completed.
However, these settings do not affect any subprocesses that are part of the process model. Subprocesses have their own archival settings that can be configured separately. References: Automatic Process Clean-up Settings, Archiving Processes
NEW QUESTION # 21
You need to show joined data from 5 tables. Each table contains a large number of rows and could generate a large result set after executing the Joins.
The business is not expecting live data, and a 2-hour refresh is acceptable. Performance is a top priority.
What should you use? (Choose the best answer.)
- A. View
- B. Table
- C. Materialized view
- D. Stored procedure
Answer: C
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 # 22
You need to insert the deleted row of a table into a history table for audit purposes.
What is the most efficient method to achieve this?
- A. Process model
- B. Materialized view
- C. View
- D. Trigger
Answer: D
Explanation:
Explanation
The most efficient method to insert the deleted row of a table into a history table for audit purposes is Trigger.
This is because a trigger is a database object that automatically executes a specified SQL statement when a certain event occurs on a table or view. A trigger can be defined to run before or after a delete operation on a table, and can access the deleted row using a special table called deleted. A trigger can perform the insertion of the deleted row into the history table without any additional logic or overhead from Appian. References: Triggers
NEW QUESTION # 23

- A. The view doesn't have a column mapped as a Primary Key in its corresponding CDT.
- B. The rule contains a missing syntax.
- C. The required inputs were not provided.
- D. The view contains a large number of rows, requiring more time to fetch the data.
Answer: D
NEW QUESTION # 24

NEW QUESTION # 25
Which XSD element is NOT supported within an Appian CDT? (Choose the best answer.)
- A. <xsd:simpleContent>
- B. <xsd:annotation>
- C. <xsd:complexType>
- D. <xsd:key>
Answer: D
Explanation:
Explanation
The xsd:key element is not supported within an Appian CDT. This element is used to define a key constraint for an element or a group of elements. Appian does not support key constraints in CDTs, as they are not relevant for data storage or manipulation. Instead, Appian uses primary keys and foreign keys to enforce uniqueness and referential integrity in CDTs. These keys are specified using the @Id and @JoinColumn JPA annotations, respectively. References: Supported XSD Elements and JPA Annotations

NEW QUESTION # 27
You need to show joined data from 5 tables. Each table contains a large number of rows and could generate a large result set after executing the Joins.
The business is not expecting live data, and a 2-hour refresh is acceptable. Performance is a top priority.
What should you use? (Choose the best answer.)
- A. View
- B. Table
- C. Materialized view
- D. Stored procedure
Answer: C
Explanation:
Explanation
A materialized view is the best option to show joined data from 5 tables that contain a large number of rows and could generate a large result set after executing the joins. A materialized 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. A materialized view can improve performance by reducing the execution time of complex queries that involve multiple joins, aggregations, or calculations. A materialized view can also reduce the load on the database server by storing the query results in advance. A materialized view can be refreshed at regular intervals or on demand to reflect the changes in the underlying tables. References: [Materialized Views], [View Performance]

NEW QUESTION # 31
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. Limit the number of series values and categories in the report.
- B. Display the report as a task report on the Tasks tab.
- C. Use the query process analytics function to retrieve the data.
- D. Use local variables in your report interface to avoid redundant database queries.
- E. Perform aggregation in the database using a view prior to reading the data into Appian.
Answer: A,D,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
NEW QUESTION # 32
You have a requirement that can only be achieved by using a plug-in, where more than one plug-in does a similar job.
What are three primary considerations in choosing the right plugin? (Choose three.)
- A. What are the compatible Appian versions?
- B. What is the size of the plug-in?
- C. What are the limitations of the plug-in?
- D. Is the plug-in Cloud-approved?
- E. Who is the plug-in author?
Answer: A,C,D
Explanation:
Explanation
The question is about choosing the right plug-in for a requirement that can only be achieved by using a plug-in. The following are three primary considerations in choosing the right plug-in:
* What are the compatible Appian versions? This is important because some plug-ins may not work with older or newer versions of Appian due to changes in APIs or features. You should check the plug-in
* documentation or release notes to see which Appian versions are supported by the plug-in.
* Is the plug-in Cloud-approved? This is important because some plug-ins may not be allowed in Appian Cloud environments due to security or performance reasons. You should check the Appian Cloud Approved Plug-ins list to see which plug-ins are approved for use in Appian Cloud.
* What are the limitations of the plug-in? This is important because some plug-ins may have known issues or limitations that could affect your requirement or use case. You should check the plug-in documentation or forums to see if there are any reported bugs or limitations for the plug-in.
The following are not primary considerations in choosing the right plug-in:
* What is the size of the plug-in? This is not a major factor, as plug-ins are usually small in size and do not affect the performance or storage of Appian significantly. However, you should still follow the best practices for managing plug-ins and avoid installing unnecessary or unused plug-ins.
* Who is the plug-in author? This is not a decisive factor, as plug-ins can be authored by Appian, third-party vendors, or community members. However, you should still consider the reputation and reliability of the plug-in author and check their support and update policies.
