Correct Answer: A

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.

Correct Answer: C

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. References: Relational Database Guidance Views

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.

Correct Answer: C

The question is about AMUs (Appian Memory Units), which is a metric that measures the memory usage of a process model. The following statement is correct regarding this metric:

Memory usage is considered low when it is below 100,000 AMUs. This is based on the Appian recommendation that each process model should use less than 100,000 AMUs on average, as higher memory usage can affect the performance

or stability of Appian.

The following statements are not correct regarding this metric:

Memory usage is considered low when it is below 10,000 AMUs. This is too low, as most process models will use more than 10,000 AMUs on average, depending on their complexity and data size.

Memory usage is considered low when it is below 1,000 AMUs. This is too low, as even simple process models will use more than 1,000 AMUs on average, depending on their configuration and parameters. AMUs is not a good measurement

for process memory usage. This is not true, as AMUs is a standardized and consistent measurement that reflects the relative memory usage of different process models in Appian.

Correct Answer: ABC

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. References: Plug-ins Appian Cloud Approved Plug-ins

Correct Answer: BD

When creating a Web API, you need to configure two items in the Administration Console: an API key and a service account. An API key is a unique identifier that is used to authenticate requests to your Web API. You can create and manage API keys in the Administration Console under Integration > API Keys. A service account is a user account that is used to execute the Web API expression rule. You can select a service account in the Administration Console under Integration > Web APIs when you create or edit a Web API. References: [Web APIs], [API Keys], [Service Accounts]

Correct Answer: B

The question is about a sign that an application's performance is degrading and should be addressed with changes to the application design. The following is a sign of this: Three of the top five most executed process models have a low completion percentage. This means that a large proportion of the process instances are not reaching the end event, either because they are taking too long to complete, or because they are encountering errors or exceptions. This can affect the performance of the application, as it can consume more memory and resources, and reduce the availability and reliability of the application. You should review the process model design and identify the causes of the low completion rate, and make changes to improve the process efficiency and error handling. The following are not signs of performance degradation that require changes to the application design: Integration calls to an external system are consistently returning an HTTP status code of 500. This means that the external system is experiencing an internal server error, which is not related to the application design. You should contact the external system provider and report the issue, or implement a fallback or retry mechanism in your integration logic. The number of tasks assigned to users has increased from 1 per day to 5 per day. This means that the workload or demand for the application has increased, which is not necessarily a sign of performance degradation. You should monitor the task completion rate and user feedback to see if the increase in tasks is affecting the user experience or satisfaction, and adjust the task assignment or prioritization logic if needed. The number of objects in the Application has increased from about 100 to about 500. This means that the application has grown in size and complexity, which is not necessarily a sign of performance degradation. You should follow the best practices for application design and maintenance, such as using folders, prefixes, dependencies, and documentation, to keep the application organized and manageable.

Correct Answer: B

Creating a trigger on the database table to capture the audit trail to a table is the most efficient and has the least impact on the Appian application, because it avoids adding extra logic or calls to the Appian application, which could affect its performance and scalability. A trigger is a database object that automatically executes when a specified event occurs on a table or view. A trigger can be used to insert, update, or delete data from another table based on the changes made to the original table. References: [Triggers], [Audit Trail]

Correct Answer:

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. References: Pie Chart Line Chart Bar Chart
