What are three prerequisites for designing the integration?

A. Understand the content of the expected body, including each field type and their limits. B. Understand whether this integration will be used in an interface or in a process model. C. Understand the business rules to be applied to ensure the business logic of the data. D. Define the HTTP method that the integration will use. E.

Question 2

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 the changes directly in PROD. 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. B. 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. C. 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. D. 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.

Question 3

You are planning a strategy around data volume testing for an Appian application that queries and writes to a MySQL database. You have administrator access to the Appian application and to the database. What are two key considerations when designing a data volume testing strategy?

A. Large datasets must be loaded via Appian processes. B. Data from previous tests needs to remain in the testing environment prior to loading prepopulated data. C. The amount of data that needs to be populated should be determined by the project sponsor and the stakeholders based on their estimation. D. Data model changes must wait until towards the end of the project. E. Testing with the correct amount of data should be in the definition of done as part of each sprint.

Question 4

You are designing a process that is anticipated to be executed multiple times a day. This process retrieves data from an external system and then calls various utility processes as needed. The main process will not use the results of the utility processes, and there are no user forms anywhere.
Which design choice should be used to start the utility processes and minimize the load on the execution engines?

A. Start the utility processes via a subprocess asynchronously. B. Start the utility processes via a subprocess synchronously. C. Use the Start Process Smart Service to start the utility processes. D. Use Process Messaging to start the utility process.

Question 5

What are two advantages of having High Availability (HA) for Appian Cloud applications?

A. A typical Appian Cloud HA instance is composed of two active nodes. B. In the event of a system failure, your Appian instance will be restored and available to your users in less than 15 minutes, having lost no more than the last 1 minute worth of data. This is an advantage of having HA, as it guarantees a high level of service availability and reliability for your Appian instance. If one of the nodes fails or becomes unavailable, the other node will take over and continue to serve requests without any noticeable downtime or data loss for your users. C. In the event of a system failure, your Appian instance will be restored and available to your users in less than 15 minutes, having lost no more than the last 1 minute worth of data. D. An Appian Cloud HA instance is composed of multiple active nodes running in different availability zones in different regions. E. Data and transactions are continuously replicated across the active nodes to achieve redundancy and avoid single points of failure.
