Appian Senior Developer Sample Questions (Q27-Q32):

NEW QUESTION # 27
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. Avoid fetching the total count when getting transactions.
B. Use a synced record for Transactions to improve the query response time for the query performed on line 6.
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 # 28
You need to configure your process model to store the result of an expression rule for every item in a list.
Your design must have the smallest memory footprint.
What should you do?

A. Invoke a sub-process for each item in the list.
B. Execute MNI over a script task for 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. Configure a script task to use a!forEach() to iterate over each item in the list.

Answer: D

Explanation:
Configuring a script task to use a!forEach() to iterate over each item in the list allows you to process all items within a single task, minimizing the memory footprint compared to multiple subprocesses or smart service loops.

NEW QUESTION # 29
You're developing a functionality to manage transactions for an insurance company. Each transaction can have multiple items where respective item type and item amount can be entered. The amount entered can be either negative or positive, and is a decimal data type with a precision of 8 and a scale of 2.
A maximum of 10 items can be entered for a transaction. Once all the items are entered, you need to calculate and show the sum of all items' total amounts at the transaction level.
What is the best way to calculate and display the sum of all item amounts?

A. fixed(sum(ri!items.amount),2,false())
B. round(sum(ri!items.amount),2)
C. text(sum(ri!items.amount),"00.00")

Answer: A

Explanation:
fixed(sum(ri!items.amount),2,false()) is the best option because it returns the sum as a text value formatted to exactly two decimal places, which is ideal for currency or financial amounts. This ensures the total displays correctly as a string, maintaining precision and formatting for both positive and negative values.

NEW QUESTION # 30
You're conducting a design review.
You identify slow-performing expression rules querying a specific data store, and need to understand the
"number of operations against data stores."
Which metric from the data_store_details.csv file is helpful to you?

A. TCCCotal Count
B. Execute Count
C. Query Count

Answer: C

Explanation:
The "Query Count" metric in the data_store_details.csv file indicates the number of operations (queries) performed against data stores, helping you analyze data store usage.

NEW QUESTION # 31
An insurance application has a dashboard in which all the cases with "Accident" case type and "Health Insurance" insurance type are displayed to the user, using the following query:

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?

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".
