Appian ACD200 Online Questions & Answers

• Question 21:

  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. Don't fetch total count when getting transactions.
  B. On line 4, increase the paginginfo batch size to 50 so more data is prefetched.
  C. Use a synced record for Transactions to improve the query response time for the query performed on line 6.
  D. Prefetched transation types and use the displayvalue() function to display the Transaction Type for each transaction.
  D. Prefetched transation types and use the displayvalue() function to display the Transaction Type for each transaction.

  ---

  Explanation/Reference:

  The load time of this interface component can be improved by reducing the number of queries performed and the amount of data transferred. One way to achieve this is to prefetch the transaction types and use the displayvalue() function to display the Transaction Type for each transaction. This way, only one query is performed to get the transactions, and the transaction types are retrieved from a local variable instead of a separate query. This reduces the network latency and the database load, which can improve the performance of the interface. Therefore, the best answer is D. References: Prefetching Data displayvalue() Function

• Question 22:

  You are referencing and using arrays of a CDT (Custom Data Type).

  Which two statements are true? (Choose two.)

  A. Other Appian functions can be used within the square brackets "[]" when using dot notation to return specific data from the array.
  B. There is no difference between using "dot notation" and the index() function.
  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. The function where contains can act on operands of different types.
  B. There is no difference between using "dot notation" and the index() function.
  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.

  ---

  Explanation/Reference:

  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.

  C. Application Viewers
  D. Application Administrators Group
  E. Application Editors
  A. Specified Reviewer Group
  B. System Administrators
  D. Application Administrators Group

  ---

  Explanation/Reference:

  The question is about approving or rejecting an incoming deployment. The following roles allow you to do so:

  Specified Reviewer Group: This is a group that can be specified by the application administrator when creating a deployment package. Members of this group can approve or reject the deployment package in the target environment. System

  Administrators: This is a group that has full access and control over all applications and system settings in Appian. Members of this group can approve or reject any deployment package in any environment. Application Administrators Group:

  This is a group that has full access and control over a specific application in Appian. Members of this group can approve or reject any deployment package for their application in any environment. The following roles do not allow you to

  approve or reject an incoming deployment:

  Application Viewers: This is a group that has read-only access to a specific application in Appian. Members of this group cannot approve or reject any deployment package for their application in any environment. Application Editors: This is a

  group that has edit access to a specific application in Appian. Members of this group can create and export deployment packages for their application in any environment, but they cannot approve or reject them.

• Question 24:

  You are required to test a Related Action that updates record data. You need to make sure that the correct users can access the form and that the data is updating successfully.

  Which is the most appropriate testing method to achieve this using Appian?

  A. Unit Testing
  B. User Interface (UI) Testing
  C. Load Testing
  D. Performance Testing
  A. Unit Testing

  ---

  Explanation/Reference:

  The most appropriate testing method to achieve this using Appian is Unit Testing. This is because unit testing allows you to test individual components of your application, such as forms, rules, or expressions, in isolation from other components or dependencies. Unit testing can help you verify that your Related Action works as expected for different users and data scenarios, as well as identify and fix any errors or bugs before deploying your application to production. References: Unit Testing

• Question 25:

  You are troubleshooting a process model instance with an error in a node.

  Which two options will allow you to obtain more information about the error? (Choose two.)

  A. Open the process model from the process instance.
  B. View the Process Details dialog.
  C. View the process model properties.
  D. View the properties dialog of the affected node.
  B. View the Process Details dialog.
  D. View the properties dialog of the affected node.

  ---

  Explanation/Reference:

  When troubleshooting a process model instance with an error in a node, two options that can provide more information about the error are to view the Process Details dialog and to view the properties dialog of the affected node. The Process Details dialog shows the status, history, and variables of the process instance, as well as any errors or warnings that occurred during the execution. The properties dialog of the affected node shows the configuration, inputs, outputs, and expressions of the node, as well as any errors or warnings that occurred during the evaluation. These options can help to identify the cause and location of the error, and to apply any necessary fixes. Therefore, the correct answers are B and

  D.

• Question 26:

  More than one user is editing the same record in database.

  With XSD, how do you avoid the collision of data from Application? (Choose the best answer.)

  A. @Version
  B. @OrderBy
  C. @inheritance
  D. @AssociationOverrides
  A. @Version

  ---

  Explanation/Reference:

  The @Version annotation is used to avoid the collision of data from an application when more than one user is editing the same record in a database. The @Version annotation enables optimistic locking, which is a mechanism to detect and prevent concurrent updates on the same record. Optimistic locking assumes that multiple transactions can complete without affecting each other, and that therefore transactions do not need to lock data resources until they are ready to commit. However, if a transaction tries to commit changes to a record that has been modified by another transaction since it was last read, an OptimisticLockException is thrown and the transaction is rolled back. The @Version annotation can be applied to a field or property of a CDT that stores a numeric value. This value is used as a version number that is automatically incremented by Appian every time the record is updated.

• Question 27:

  Your organization is considering options for integrating with external systems from within Appian.

  Which Appian object is designed to allow you to share base URL and authentication details across multiple integrations? (Choose the best answer.)

  A. A web API
  B. An integration
  C. A connector function
  D. A connected system
  D. A connected system

  ---

  Explanation/Reference:

  A connected system is an Appian object that is designed to allow you to share base URL and authentication details across multiple integrations4. A connected system represents an external system that is integrated with Appian. Connected systems allow you to easily connect to external integrations and data sources. They also allow you to deploy connection information across environments and use different connection information for each environment. You can choose from different types of connected systems, such as HTTP, SQL, or pre-built connected systems for common services like Google Drive or Salesforce5.

• Question 28:

  Your organization is considering the adoption of Behavior-Driven Development (BDD) and automated testing as part of application development.

  Which three testing tools have packages preconfigured to work with Appian applications and are available via the AppMarket? (Choose three.)

  A. Cucumber
  B. Jenkins
  C. Selenium API
  D. Git
  E. FitNesse
  A. Cucumber
  C. Selenium API
  E. FitNesse

  ---

  Explanation/Reference:

  The question is about the testing tools that have packages preconfigured to work with Appian applications and are available via the AppMarket. The following are three testing tools that meet these criteria:

  Cucumber: This is a tool that supports Behavior-Driven Development (BDD) and automated testing by allowing users to write test scenarios in plain language and execute them using step definitions. Cucumber has a package called Appian

  Cucumber Test Framework that provides a set of predefined step definitions and helper methods for testing Appian applications.

  Selenium API: This is a tool that allows users to automate web browser interactions and test web applications. Selenium API has a package called Appian Selenium Framework that provides a Java library and a set of helper methods for

  testing Appian applications.

  FitNesse: This is a tool that allows users to create and run acceptance tests using wiki pages and tables. FitNesse has a package called Appian FitNesse Testing Framework that provides a set of fixtures and helper methods for testing

  Appian applications.

  The following are not testing tools that have packages preconfigured to work with Appian applications and are available via the AppMarket:

  Jenkins: This is a tool that allows users to automate software development tasks such as building, testing, and deploying applications. Jenkins does not have a package specifically for Appian applications, but it can be integrated with other

  testing tools such as Cucumber or Selenium API.

  Git: This is a tool that allows users to manage version control and collaboration for software projects. Git does not have a package specifically for Appian applications, but it can be used to store and share test scripts or scenarios created by other testing tools.

• Question 29:

  You are creating an expression rule that will be reused throughout your environment.

  What are two benefits of including meaningful test cases when creating a new expression rule? (Choose two.)

  A. Speed up unit, regression, and exploratory testing.
  B. Improve the appearance of the code.
  C. Improve performance.
  D. Increase code quality.
  A. Speed up unit, regression, and exploratory testing.
  D. Increase code quality.

• Question 30:

  An organization has decided to integrate with a third-party to scan incoming documents and capture the details in a table called [appian].[document]. Each document will form a new case in Appian to be displayed on a Record List.

  The record needs to show data from both [appian].[document] and [appian].[caseData], which holds additional case information.

  What is the most efficient way to achieve this?

  A. Create a trigger on the [appian].[document] table to copy all the data across to the [appian].[caseData] table and point the record at [appian].[caseData].
  B. Create a SSIS package to run at a regular interval.
  C. Create a view between both the [appian].[document] and [appian].[caseData] tables to feed the record.
  D. Create a stored procedure to query the data from both the [appian].[document] and [appian].[caseData] tables.
  C. Create a view between both the [appian].[document] and [appian].[caseData] tables to feed the record.

  ---

  Explanation/Reference:

  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
