Appian Certified Lead Developer Sample Questions:
You have 5 applications on your Appian platform in production. Users are now beginning to use multiple applications across the platform, and the client wants to ensure a consistent user experience across all applications You notice that some applications use rich text some use section layouts, and others use box layouts. The result is that each application has a different color and size for the header.
What would you recommend to ensure consistency across the platform?
- A. In the common application, create one rule for each application, and update each application to reference its respective rule
- B. In the common application, create a rule that can be used across the platform for section headers, and update each application to reference this new rule
- C. Create constants for text size and color, and update each section lo reference these values.
- D. In each individual application, create a rule that can be used lot tot section headers, and update each application lo reference its respective rule

For each requirement, match the most appropriate approach to creating or utilizing plug-ins Each approach 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.
Correct Answer:
Explanation
Requirement: Read barcode values from images containing barcodes and QR codes. Correct approach: C.
Smart Service plug-in Exact explanation of correct approach taken from Appian Documentation: A smart service plug-in is a type of plug-in that allows you to create custom smart services that can be used in process models. A smart service can perform complex logic, interact with external systems, or manipulate data in Appian. A smart service plug-in can also leverage Java code to implement the functionality of the smart service. A smart service plug-in would be suitable for reading barcode values from images, as it can use Java libraries or APIs that can scan and decode barcodes and QR codes from image files. A smart service plug-in can also return the barcode values as outputs that can be used by other nodes or processes in Appian. A smart service plug-in can also be configured with input parameters, such as the image file, the barcode type, or the output format, that can customize the behavior of the smart service. A smart service plug-in can also have error handling and logging features that can handle any exceptions or failures that might occur during the barcode reading process.
Requirement: Display an externally hosted geolocation mapping applications interface within Appian to allow users of Appian to see where a customer (stored within Appian)is located. Correct approach: A. Web-content field Exact explanation of correct approach taken from Appian Documentation: A web-content field is a type of user interface component that allows you to display web content from an external source in a SAIL interface. A web-content field would be suitable for displaying an externally hosted geolocation mapping applications interface, as it can embed the web content in an iframe and render it within the Appian interface.
You can also pass parameters to the web content, such as the customer's location, using the url parameter of the web-content field. A web-content field can also interact with other components in the Appian interface, such as buttons, grids, or forms, using the postMessage API. This way, you can create a seamless user experience that integrates the external geolocation mapping applications interface with the Appian functionality.
Requirement: Display an externally hosted geolocation mapping applications interface within Appian to allow users of Appian to select where a customer is located and store the selected address in Appian. Correct approach: A. Web-content field and C. Smart Service plug-in Exact explanation of correct approach taken from Appian Documentation: A web-content field and a smart service plug-in would be suitable for displaying an externally hosted geolocation mapping applications interface within Appian to allow users of Appian to select where a customer is located and store the selected address in Appian. A web-content field would be suitable for displaying the external geolocation mapping applications interface, as explained above. A smart service plug-in would be suitable for storing the selected address in Appian, as it can use Java code to receive the address data from the web content, validate it, and write it to a data store entity or a process variable.
Requirement: Generate a barcode image file based on values entered by users. Correct approach: B.
Component plug-in Exact explanation of correct approach taken from Appian Documentation: A component plug-in is a type of plug-in that allows you to create custom user interface components that can be used in SAIL interfaces. A component plug-in can also leverage Java code to implement the functionality of the component. A component plug-in would be suitable for generating a barcode image file, as it can use Java libraries or APIs that can encode values into barcode formats and generate image files. A component plug-in can also display the barcode image file in the Appian interface and allow users to download or print it. A component plug-in can also interact with other components in the Appian interface, such as text fields, buttons, or forms, using the a!refreshVariable() function. This way, you can create a dynamic user experience that updates the barcode image file based on the values entered by users.
You have an active development team (Team A) building enhancements for an application (App X'). and ate currently using the TEST environment for UAT.
A separate operations team ('Team B) discovers a critical error in the Production instance of App X that they must remediate However. Team 6 does not have a hotfix stream for which to accomplish this The available environments are DEV. TEST, and PROD Which risk mitigation effort should both teams employ to ensure Team AS capital project is only minorly interrupted, and Team B s critical fix can be completed and deployed quickly to end users?
- A. Team 8 must address changes in the TEST environment These changes can then be tested and deployed directly to PROD. Once the deployment is complete. Team B can then communicate their changes to Teams to ensure they are Incorporated as a part of the next release.
- B. Team 8 must communicate to Team A which component will be addressed in the hotfix to avoid overlap of changes It overlap exists, the component must be versioned to its PROD state before being remediated and deployed, and then versioned back to its latest development state If overlap does not exist, the component may be remediated and deployed without any version changes
- C. Team A must analyze their current codebase in OEV lo merge the hotfix changes into their latest enhancements. Team B is then requited to wait for the hotfix to follow regular deployment protocols from DEV to the PROO environment.
- D. Team 8 must address the changes directly in PROD. As there is no hotfix stream, and OEV and TEST are being utilized for active development it is best to avoid a conflict of components. Once Team A has completed their enhancements work. Team 6 can update DEV and TEST accordingly.
Correct Answer: B 🗳️
Explanation: Only visible for Pass4training members. You can sign-up / login (it's free).
Your Appian project just went live with the following environment setup; DEV > TEST (SIT/DAT) > PROD Your client is considering adding a support team to manage production defects and minor enhancements, white the original development team focuses on Phase 2 Your client is asking you for a new environment strategy that will have the least impact on Phase 2 development work.
Which option involves the lowest additional server cost and the least code retrofit effort?
- A. Phase 2 development work stream: OEV > TEST (Srr/DAT) > PROO Production support work stream. DEV2 > TEST (SIT/UAT) > PROD
- B. Phase 2 development work steam: DEV > TEST (SIT) > STAGE (UAT) > PROO Production support work stream DEV > TEST2 (SIT/UAT)>PROO
- C. Phase 2 development work stream: DEV > TEST (SIT/UAT) >PROD Production support work stream DEV > TEST2 (SIT/UAT) > PROO
- D. Phase 2 development work Stream: DEV > TEST (SIT) > STAGE (UAT) > PROO Production support work stream DEV2 > STAGE (S1T/UAT) > PROD
