質問 # 21
You want to generate an email body which varies from one Appian environment to another. For instance, between DEV and TEST.
According to Appian best practices, how should you define the environment name? (Choose the best answer.)
- A. Create an environment-specific constant.
- B. Create a constant and update its value post-deployment.
- C. Create a stored procedure.
- D. Create an expression rule and update its value post-deployment.
正解：A
解説：
Explanation
According to Appian best practices, environment-specific constants should be used to define values that vary from one Appian environment to another. For example, if you want to generate an email body that contains the environment name, you can create a constant named ENVIRONMENT_NAME and assign it different values for DEV and TEST environments. This way, you can avoid hard-coding values in your expressions or rules, and simplify your deployment process by using automatic constant value mapping.
質問 # 22

質問 # 23
The IT stakeholder wants to understand which processes have the highest footprint.
What are the two places to get information on process model memory usage? (Choose two.)
- A. Administration Console
- B. Appian Health Check report
- C. Process monitoring tab
- D. Application server log file
正解：B、C
解説：
Explanation
Two places to get information on process model memory usage are:
* Process monitoring tab. The process monitoring tab is a feature in the Appian Designer that allows you to monitor and manage the performance and status of process models and instances. You can use the process monitoring tab to view various metrics and statistics about your processes, such as memory usage, execution time, node count, error count, etc. You can also filter, sort, and export the data for further analysis. The process monitoring tab can help you identify which processes have the highest memory footprint and potential performance issues.
* Appian Health Check report. The Appian Health Check report is a tool that provides insights into application design patterns and performance risks in your environment. The report covers four areas of your environment: design, user experience, infrastructure, and configuration. The report also includes graphs highlighting historical trends, such as user activity, average response times, and resource utilization. The Appian Health Check report can help you identify which processes have the highest memory consumption and suggestions for mitigating them.

質問 # 24
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 call a Sub-Process node to initialize a review process model for the reviewer.
- B. When all case details are entered, the process flow will proceed and assign a task to the reviewer to review the record.
- C. 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.
- D. When all case details are entered, the process flow will call a Start Process node to initialize a review process model for the reviewer.
正解：C
解説：
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.

質問 # 25
You need to create a service account for a consumer to access the Appian Web API.
Which user type should be created?
- A. Basic User
- B. Initiator
- C. System Administrator
- D. Editor
正解：A
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 # 26
You are using pie charts.
What is correct representation of Appian best practices? (Choose the best answer.)
- A. Try to use multiple pie charts when comparing multiple sets of data.
- B. Use pie charts to show proportional data.
- C. Pie charts should only be used to represent data that can be placed into identical categories.
- D. Use as many slices as possible.
正解：B
解説：
Explanation
The correct representation of Appian best practices for using pie charts is to use pie charts to show proportional data. Pie charts are generally used to show how individual parts contribute to a whole, such as percentages or fractions. Pie charts should only be used to represent data that can be placed into distinct categories and should not consist of more than 6 slices. Pie charts should also include value and category labels for each slice, and sort the data values in ascending or descending order. References: Pie Chart Component, Charts UX Design Guide
質問 # 27
You need to create a plug-in to perform a job in the background. The plug-in should not be available under an expression rule, connected system, or the process model.
What type of plug-in should you create? (Choose the best answer.)
- A. Connected systems
- B. Servlet
- C. Function
- D. Smart service
正解：B
解説：
Explanation
The type of plug-in that should be created to perform a job in the background and not be available under an expression rule, connected system, or the process model is a servlet plug-in. A servlet plug-in is a plug-in that allows you to create custom servlets that can be accessed through a URL. Servlets are Java classes that run on a web server and handle requests and responses. Servlet plug-ins can be used to perform background tasks, such as sending notifications, logging events, or integrating with external systems, without exposing them to the end users or developers. References: Servlet Plug-ins, Appian Suite Plug-ins

- A. A large number of smart service nodes are configured in the process model.
- B. A large value is configured for days until archival or deletion compared to other process models in your application.
- C. The process instances are long-lived compared to the configured days until archival or deletion.
- D. A large number of instances are encountering process errors, and they are not being addressed by the production support team.
正解：C、D
質問 # 29
Which two statements about the a!queryEntity() function are true? (Choose two.)
- A. The queries defined using the query parameter return a constrained subset of matching data records by default.
- B. The entity value must be given as a constant of type Data Store Entity.
- C. The queries defined using the query parameter are not limited in how long they wait to return results.
- D. Setting the fetchTotalCount parameter to False can improve the performance of the rule.
正解：B、D
質問 # 30
You are presenting data through data visualization.
Match the chart types to the data they are best suited to represent. Each answer will be used once.
Note: To change your responses, you may deselect your response by clicking the blank space at the top of the selection list.
正解：
解説：
Explanation
The question is about presenting data through data visualization and matching the chart types to the data they are best suited to represent. The following are the correct matches:
* A pie chart is best suited to represent proportional data in one category and can help us understand the contribution of parts to a whole. A pie chart shows the relative size of each part as a slice of a circular pie, and can display percentages or absolute values. For example, a pie chart can show the market share of different smartphone brands in one country.
* A line chart is best suited to represent direct comparison of data with multiple categories with a relatively small set of positive and negative values. A line chart shows the change or trend of data over time or another variable, and can display multiple lines for different categories. For example, a line chart can show the temperature change of different cities over a year.
* A bar chart is best suited to represent values across a relatively large number of categories that are not sequential or time-based. A bar chart shows the magnitude or frequency of data using horizontal or vertical bars, and can display multiple bars for different categories. For example, a bar chart can show the number of students enrolled in different courses in a university.

質問 # 31
In the next year, you expect the number of concurrent active users of your application to increase from approximately 50 to 500.
Which two recommendations for your Appian environment would address the performance risk of this large increase in users? (Choose two.)
- A. Add more process execution engines.
- B. Add more application server memory.
- C. Add more design engines.
- D. Switch from a records-centric to a process-centric design.
正解：A、B
解説：
Explanation
The question is about the recommendations for Appian environment to address the performance risk of a large increase in users. The following are two recommendations for this purpose:
* Add more process execution engines. This means adding more servers or nodes that can execute process instances in parallel, which can improve the scalability and availability of Appian. This can help handle the increased workload and demand from more users without affecting the response time or reliability of Appian.
* Add more application server memory. This means increasing the amount of memory allocated to each server or node that runs Appian components, such as web servers, engines, or analytics servers. This can help improve the performance and stability of Appian by reducing memory pressure and garbage collection.
The following are not recommendations for Appian environment to address the performance risk of a large increase in users:
* Add more design engines. This means adding more servers or nodes that can execute expression rules or interface components in parallel, which can improve the performance and scalability of Appian.
However, this is not directly related to the number of users, but rather to the complexity and frequency of expression rules or interface components in the application.
* Switch from a records-centric to a process-centric design. This means changing the application design to focus more on process models and tasks, rather than records and reports. This does not affect the Appian environment, but rather the application logic and functionality. This may or may not improve the performance of the application, depending on the requirements and use cases.

* Memory Recommendations
* Design Engines
* Records-Centric vs Process-Centric Design

According to Appian best practices, what is the preferred style and size for the images?
- A. style: "AVATAR"
size: "LARGE" - B. style: "AVATAR"
size: "SMALL" - C. style: "STANDARD"
size: "LARGE" - D. style: "STANDARD"
size: "ICON"
正解：B
質問 # 34
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 required inputs were not provided.
- B. The rule contains a missing syntax.
- C. The view doesn't have a column mapped as a Primary Key in its corresponding CDT.
- D. The view contains a large number of rows, requiring more time to fetch the data.
正解：D
解説：
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]
質問 # 35
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 call a Sub-Process node to initialize a review process model for the reviewer.
- B. When all case details are entered, the process flow will proceed and assign a task to the reviewer to review the record.
- C. 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.
- D. When all case details are entered, the process flow will call a Start Process node to initialize a review process model for the reviewer.
正解：C
