Integration-Architect Questions Bank

The system types, the error handling mechanisms, and the data volume and processing volume are three constraints and pain-points that an integration architect should consider when choosingthe integration pattern/mechanism. The system types determine what kind of interfaces and protocols are available or required for the integration, such as APIs, file systems, email, etc. The error handling mechanisms ensure that the integration can handleany failures or exceptions gracefully and provide appropriate logging and notification.The data volume and processing volume affect the performance and scalability of the integration, as well as the choice of synchronous or asynchronous methods.

Option B is correct because platform events are published after the Apex transaction completes. Platform events are asynchronous messages that are published and consumed by different processes or systems. When an Apex transaction publishes a platform event, the event is not sent immediately, but rather added to a temporary queue. The event is only published and delivered to the subscribers after the Apex transaction commits successfully. This ensures that the event data is consistent with the database state and that the event is not lost in case of a rollback.

Option A is incorrect because platform events are not published immediately before the Apex transaction completes. As explained above, platform events are published after the Apex transaction commits successfully. Publishing events before the transaction completes can cause data inconsistency and event loss issues.

Option C is incorrect because platform events can have a trigger in Apex, but this is not related to the question of when events are published. A platform event trigger is a special type of Apex trigger that executes when a platform event message is received by Salesforce. A platform event trigger can perform logic based on the event data, such as updating records, sending notifications, or calling external services. A platform event trigger does not affect the publishing of events, but rather the consumption of events.

Option D is incorrect because platform events can be published from Apex, but this does not answer the question of when events are published. Platform events can be published from various sources, such as Apex code, Process Builder, Flows, or API calls. Publishing events from Apex requires creating an instance of a platform event object and using the EventBus.publish method to add it to the temporary queue. The actual publishing of events happens after the Apex transaction completes, regardless of the source of the events.

Create a special user solely for the integration purposes. This is the first thing that the Architect should do when building a solution that allows a service to access Salesforcethrough the API. Creating a special user for the integration purposes can help to ensure security, accountability, and traceability of the API calls. The special user should have a unique username, password, security token, and profile that grants only thenecessary permissions and access for the integration. The special user should also be assigned to an API-only user license type that prevents logging in to the Salesforce UI.

Option D is correct because Tooling API is the Salesforce API that can be used to retrieve code coverage and test results for Apex classes and triggers. Tooling API provides REST and SOAP interfaces to access metadata about code, execute tests, and get test results12

Option A is incorrect because SOAP API is a Salesforce API that can be used to create, retrieve, update, or delete records, but not to get code coverage and test results. SOAP API uses a WSDL file to define the parameters for accessing data through the API3

Option B is incorrect because Analytics REST API is a Salesforce API that can be used to access data from reports and dashboards, but not from code coverage and test results. Analytics RESTAPI provides a programmatic way to interact with analyticsfeatures such as lenses, datasets, and dashboards4

Option C is incorrect because Metadata API is a Salesforce API that can be used to retrieve, deploy, create, update, or delete customization information, such as custom object definitions and page layouts, but not code coverage and test results. Metadata API is mainlyused for development tools or backup tools5
