Correct Answer: BC

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.

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

Correct Answer: A

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]
