Appian Certified Lead Developer Sample Questions:

1. Your team has deployed an application to Production with an underperforming view. Unexpectedly, the production data is ten times that of what was tested, and you must remediate the issue. What is the best option you can take to mitigate their performance concerns?

A) Create a materialized view or table.
B) Bypass Appian's query rule by calling the database directly with a SQL statement.
C) Create a table which is loaded every hour with the latest data.
D) Introduce a data management policy to reduce the volume of data.

2. You are asked to design a case management system for a client. In addition to storing some basic metadata about a case, one of the client's requirements is the ability for users to update a case. The client would like any user in their organization of 500 people to be able to make these updates. The users are all based in the company's headquarters, and there will be frequent cases where users are attempting to edit the same case. The client wants to ensure no information is lost when these edits occur and does not want the solution to burden their process administrators with any additional effort. Which data locking approach should you recommend?

A) Allow edits without locking the case CDI.
B) Add an @Version annotation to the case CDT to manage the locking.
C) Design a process report and query to determine who opened the edit form first.
D) Use the database to implement low-level pessimistic locking.

3. You need to generate a PDF document with specific formatting. Which approach would you recommend?

A) There is no way to fulfill the requirement using Appian. Suggest sending the content as a plain email instead.
B) Use the Word Doc from Template smart service in a process model to add the specific format.
C) Create an embedded interface with the necessary content and ask the user to use the browser "Print" functionality to save it as a PDF.
D) Use the PDF from XSL-FO Transformation smart service to generate the content with the specific format.

4. You have an active development team (Team A) building enhancements for an application (App X) and are currently using the TEST environment for User Acceptance Testing (UAT).
A separate operations team (Team B) discovers a critical error in the Production instance of App X that they must remediate. However, Team B 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 A's capital project is only minorly interrupted, and Team B's critical fix can be completed and deployed quickly to end users?

A) Team B 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 Team A to ensure they are incorporated as part of the next release.
B) Team B must address the changes directly in PRO As there is no hotfix stream, and DEV 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 B can update DEV and TEST accordingly.
C) Team B must communicate to Team A which component will be addressed in the hotfix to avoid overlap of changes. If 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.
D) Team A must analyze their current codebase in DEV to merge the hotfix changes into their latest enhancements. Team B is then required to wait for the hotfix to follow regular deployment protocols from DEV to the PROD environment.

5. You add an index on the searched field of a MySQL table with many rows (>100k). The field would benefit greatly from the index in which three scenarios?
