NEW QUESTION # 39
You need to implement a Gender dropdown, where the choice labels may need to be altered in the future. The transactional database tables rely on this data for reporting, so the data must be accurate.
What is the recommended action?
- A. Create these entries in a table and reference them through a query entity rule as per the business requirement.
- B. Create an expression rule and modify it as per the business requirement.
- C. Create a constant and modify it as needed per the business requirement.
Answer: A
Explanation:
Storing the dropdown entries in a database table and referencing them through a query entity rule ensures data integrity, flexibility for future changes, and accuracy for reporting purposes.
NEW QUESTION # 40
An insurance company's product details are currently distributed across numerous database tables, encompassing over 60 to 70 fields.
You need to implement a product comparison tool for business users to compare up to three insurance products simultaneously, with all the product details in a tabular format.
Refer to the following sample format:
Which object should be used to transform the data into the required format?
- A. VCCCiews
- B. Record type with relationships
- C. Stored procedure
Answer: A
Explanation:
Database views are ideal for transforming complex, distributed product data into a single, flattened structure tailored for reporting or comparison. In this case, a view can pivot the 60-70 fields and organize them by attribute (e.g., Name, Type, Premium) across multiple product columns, enabling a tabular comparison layout like the one shown. Views also optimize performance and reduce transformation overhead in the interface layer.
NEW QUESTION # 41
The synced record Task has a self-referential relationship defined in the column parentTaskId. There is a many-to-one record relationship between the id and parentTaskId called parentTask.
For a given task ID, you need to return the task name and the parent task name.
What should you do?
- A. Use a!queryRecordType() filtered on the task id once to return the task name and parent task ID. Query the record again to return the parent task name.
- B. Create a sync-time custom record field on the Task record called parentName. Specify this field to return in the query field selection.
- C. Use a!queryRecordType() with a filter on the task id, with fields specified to return recordType!Task.
name and recordType!Task.parentTask.name.
Answer: C
Explanation:
Using a!queryRecordType() with a filter on the task ID and specifying both recordType!Task.name and recordType!Task.parentTask.name in the fields will efficiently return both the task name and its parent task name in a single query.
NEW QUESTION # 42
You're creating a new record type with data sync enabled. Users in the "ACME Employees" group must be able to access the record list and start the New Case action.

NEW QUESTION # 47
Users are experiencing slow load times when retrieving customer records with many transactions.
After using performance monitoring tools, you discover that the following interface definition is responsible for the majority of page load time:
Additionally, both queries (rule!APP_GetTransactionsWithFilters and rule!APP_GetTransactionTypeWithFilters) take approximately 25 milliseconds each to execute when you test them using the expression editor.
Which action would result in the greatest reduction in the load time for this interface component?
- A. Use a synced record for Transactions to improve the query response time for the query performed on line 6.
- B. Avoid fetching the total count when getting transactions.
- C. Prefetch transaction types and use the displayvalue() function to display the Transaction Type for each transaction.
Answer: C
Explanation:
Prefetching all transaction types once (instead of running a separate query for each row in the grid) and then using the displayvalue() function to display the corresponding transaction type name for each transaction will significantly reduce the number of queries executed. This eliminates the N+1 query problem and will greatly improve the interface load time.
NEW QUESTION # 48
A view is created with the primary table PERSON and is joined using a left join with the APPOINTMENT table on the column "PERSON_ID". There is a one-to-many relationship between the PERSON and APPOINTMENT tables.
A Custom Data Type (CDT) and a data store entity have been created based on this view, with the primary key being "PERSON_ID".
Review the data presented in the PERSON and APPOINTMENT tables:
Which two statements are true when the following query entity is executed? (Choose two.)
- A. result totalCount is 3
- B. Appian makes one more query to the database(other than the actual query to fetch the data) to get the totalCount based on the applied filters.
- C. result totalCount is 1
- D. Appian makes one more query to the database(other than the actual query to fetch the data) to get the totalCount based on the applied filters and paging info.
Answer: B,C
Explanation:
Appian makes an additional query to the database (other than the main query for data) to retrieve the totalCount when fetchTotalCount: true() is used.
The result totalCount is 1, as there is only one person (PERSON_ID 1101) being filtered, even though there are multiple "New" appointments for that person; with a CDT based on PERSON_ID as the primary key, only one row is counted per person.

NEW QUESTION # 50
You're developing a user input form for a financial services application.
One component of this form requires you to embed an external site (in the form of a URL) that can receive inputs from Appian and return updates as the user interacts with it.
What should you do?
- A. Use the Appian out-of-the-box Web Content Component. It can display content from a URL and provide both additional inputs, or receive updates as the user interacts with the embedded site.
- B. Use an integration to achieve interaction with the embedded site while displaying information in the Appian out-of-the-box Web Content Component. That way you can refresh for updates and interact with the site.
- C. Use a component plug-in to achieve interaction with the embedded site, because this use case requires input-output or event parameters.
Answer: C
Explanation:
A component plug-in is required because the standard Web Content Component in Appian only displays external sites and does not support direct two-way interaction or input/output event handling. A plug-in enables custom integration to allow input and receive updates as users interact with the embedded site.
NEW QUESTION # 51

You need to update the query entity to display all the cases that are "Accident" case type and "Health Insurance" insurance type, or created in the last ten days.
What is the right configuration for the logical expression?
- A.
- B.
- C.
Answer: C
Explanation:
A filter for createdDate >= today() - 10 (records created in the last 10 days).
A nested AND logical expression that requires both caseType = "Accident" and insuranceType = "Health Insurance".
NEW QUESTION # 53
You receive a warning about approaching the 2,000,000 row limit with synced records in your Production environment.
What are two ways to efficiently address this warning to prevent reaching the limit? (Choose two.)
- A. Design the process to write data in batches of 1,000.
- B. Keep only necessary data and plan to move the archived data to an audit table in a longer run.
- C. Disable data sync immediately to prevent user facing-front end issues.
- D. Apply one or more source filters to limit the number of rows synced in Agpian.
Answer: B,D
Explanation:
Keeping only necessary data and moving archived data to an audit table reduces the number of synced rows, addressing the limit efficiently.
Applying source filters limits the data that is synced, preventing the total row count from exceeding the limit.
NEW QUESTION # 54
You're inspecting the items in a deployment package for issues you might have missed during package preparation.
Which two objects can be in your list of missing precedents for an application? (Choose two.)
- A. Connected System
- B. System Knowledge Center

NEW QUESTION # 55
You need to connect to an external system using OAuth 2.0: SAML Bearer Assertion Flow authentication type, which requests access to an API on of a signed in user.
This standard has several steps involved with the SAML Bearer Assertion Flow.
Which two steps should you perform to connect to the external system? (Choose two.)
- A. Generate a service account key in third-party systems.
- B. Confiqure SAML for sinqle siqn-on (SSO).
- C. Register the connection in the third-party system
- D. Use an a!authorizationLink() on the relevant interface.
Answer: B,C
Explanation:
Configure SAML for single sign-on (SSO).
The bearer-assertion flow relies on an existing SAML SSO configuration so Appian can issue a signed SAML assertion on behalf of the signed-in user.
Register the connection in the third-party system.
You must register (or "trust") Appian's client/certificate with the external system so it will accept the SAML assertion and issue an OAuth 2.0 access-token for the user.
