質問 # 47
You are investigating a slow-performing query entity which is mapped to a view and you decide to look in the data_store_details.csv log to gain more information. You see that the majority of the time is spent in the transform phase.
Which two actions can you take to reduce the time spent in the transform phase? (Choose two.)
- A. Lower the batch size parameter of the query.
- B. Reduce the use of unnecessary columns in the GROUP BY clause in the database view.
- C. Create a database index on the column being filtered against.
- D. Reduce the number of columns returned from the query.
正解：A、D
解説：
Explanation
The data_store_details.csv log provides information about the performance of query entities. The log shows the time spent in three phases: extract, transform, and load. The extract phase is the time it takes to execute the SQL query on the database. The transform phase is the time it takes to convert the SQL result set into Appian data types. The load phase is the time it takes to return the data to the expression that invoked the query entity.
To reduce the time spent in the transform phase, two possible actions are to reduce the number of columns returned from the query and to lower the batch size parameter of the query. These actions can decrease the amount of data that needs to be converted and transferred, which can improve the performance of the query entity. Therefore, the correct answers are B and D.

質問 # 48
During a sprint retrospective meeting, you need to get the team thinking about the outcomes of the last sprint.
Which two basic questions should you ask? (Choose two.)
- A. What went well?
- B. What are the blockers?
- C. What didn't go well and can be improved?
- D. Who did well in this sprint?
正解：A、C
解説：
Explanation
A sprint retrospective is a meeting that takes place at the end of each sprint, where the team reflects on what went well and what can be improved in their work process. The purpose of the retrospective is to identify and implement actions that can enhance the team's performance and satisfaction in future sprints. Two basic questions that can help facilitate the retrospective are: What went well? and What didn't go well and can be improved? These questions allow the team to celebrate their achievements, acknowledge their challenges, and generate ideas for improvement.
質問 # 49
Users are reporting that their application is slow to load customer records with many transactions.
Using performance monitoring tools, you find that the following interface definition is responsible for the vast majority of page load time:
You also notice that both queries (rule!APP_GetTransactionsWithFilters and rule!APP_GetTransactionTypeWithFilters) take about 25 milliseconds each to execute when you test them using expression editor.
Which change would decrease the load time of this interface component the most? (Choose the best answer.)
- A. Use a synced record for Transactions to improve the query response time for the query performed on line 6.
- B. Don't fetch total count when getting transactions.
- C. Prefetched transation types and use the displayvalue() function to display the Transaction Type for each transaction.
- D. On line 4, increase the paginginfo batch size to 50 so more data is prefetched.
正解：C

質問 # 54
You need to create a service account for a consumer to access the Appian Web API.
Which user type should be created?
- A. Initiator
- B. Basic User
- C. Editor
- D. System Administrator
正解：B
解説：
Explanation
The requirement is to create a service account for a consumer to access the Appian Web API. A basic user is the user type that should be created for this purpose, as it has the minimum permissions needed to invoke web APIs and does not consume a license. A basic user can also be assigned to specific groups or roles to control the access to web APIs. The other options are not suitable for this purpose, as they either have more permissions than needed or consume a license. References:
* User Types
* Web API Security
質問 # 55
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. Stored procedure
- B. Materialized view
- C. View
- D. Table
正解：B
解説：
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]
質問 # 56
You are referencing and using arrays of a CDT (Custom Data Type).
Which two statements are true? (Choose two.)
- A. The function where contains can act on operands of different types.
- B. Other Appian functions can be used within the square brackets "[]" when using dot notation to return specific data from the array.
- C. An array of integers can be passed as the second parameter to the index() function to return the data at those position in the array.
- D. There is no difference between using "dot notation" and the index() function.
正解：C、D
解説：
Explanation
The question is about referencing and using arrays of a CDT (Custom Data Type). The following statements are true:
* There is no difference between using "dot notation" and the index() function. Both methods can be used to access elements of an array by their position. For example, if a is an array of CDTs, then a[1] and index(a, 1) will return the same element.
* An array of integers can be passed as the second parameter to the index() function to return the data at those positions in the array. For example, if a is an array of CDTs, then index(a, {1, 3, 5}) will return an array of CDTs containing the elements at positions 1, 3, and 5 in a.
The following statements are false:
* Other Appian functions can be used within the square brackets "[]" when using dot notation to return specific data from the array. This is not possible, as dot notation only accepts integers or integer arrays as indices. For example, if a is an array of CDTs, then a[length(a)] will cause an error, as length(a) is not a valid index.
* The function wherecontains can act on operands of different types. This is not true, as wherecontains only works on operands of the same type. For example, if a is an array of CDTs and b is an array of integers, then wherecontains(a, b) will cause an error, as a and b are not of the same type.
References:
* Dot Notation
* index()
* wherecontains()
質問 # 57
Your organization requires a process to be initiated via an Appian web API.
Which HTTP request methods should the API use?
- A. GET
- B. POST
- C. CONNECT
- D. HEAD
正解：B
解説：
Explanation
The question is about initiating a process via an Appian web API. The HTTP request method that the API should use is POST, as it is the method that allows sending data to the server and creating or updating a resource. In this case, the data would be the process parameters and the resource would be the process instance. The other options are not suitable for this purpose, as they either do not allow sending data or do not create or update a resource. References:
* HTTP Request Methods
* Start Process Web API
質問 # 58
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."

- B. The view contains a large number of rows, requiring more time to fetch the data.
- C. The view doesn't have a column mapped as a Primary Key in its corresponding CDT.
- D. The required inputs were not provided.
正解：B
質問 # 59
You want to display a Gender dropdown, and its choice label may change in the future as per the business requirement.

- A. Create these entries in a table and reference them through a query entity rule as per the business requirement.
- B. Create a constant and update it as per the business requirement.
- C. Create an expression rule and update it as per the business requirement.
- D. Create a stored procedure and update it as per the business requirement.
正解：A
