Appian ACD200 Exam With Confidence Using Practice Dumps

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]

 A many-to-many relationship is a type of relationship where multiple records in one table are associated with multiple records in another table. To implement a many-to-many relationship, a third table is needed to store the associations between the two entities. In this case, the third table would store the employee ID and the skill ID for each pair of employee and skill. This design allows for efficient querying and updating of the data, as well as avoiding data redundancy and inconsistency. 

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.
