Questions and Answers

In Oracle Integration Cloud (OIC), which of the following actions should you perform to ensure an integration using a REST trigger with authentication only allows access to authorized clients?

Set up an IP whitelist in the OIC Instance, allowing only specific IP addresses to access the integration.

Encrypt the payload using a Custom encryption algorithm and provide the decryption key to authorized clients.

Configure the REST adapter with a Basic Authentication or OAuth 2.0 security policy and provide the required credentials. (correct)

Enable Cross-Origin Resource sharing (CORS) and set an API key in the REST adapter configuration.

What should you do before deploying an integration to a live environment?

Use the 'Test' button in the integration designer to create a request, validate the response, and review the execution logs. (correct)

Upload the integration directly to the production environment.

Export the integration as a .jar file and run it in a local development environment.

Perform a SQL query on the associated database to ensure that the expected data is present.

Which one of the following statements is NOT TRUE about Cross-Origin Resource Sharing (CORS)?

CORS is commonly used to provide access to publicly available APIs. (correct)

By default, browsers prevent web pages from making cross-domain requests to protect users from malicious attacks.

CORS enables secure cross-domain communication between a web client and a server.

Configuring CORS can prevent unauthorized clients from accessing sensitive data in OIC.

Study Notes

OIC Lookup and Integration

OIC lookups are based on a static definition, created and populated during design time and cannot be changed by runtime activities.
The connectivity agent enables creating hybrid integrations and exchanging messages between applications in private or on-premises networks and OIC.

Application-Driven Integration

An application-driven integration can contain one or more trigger (source) connections for requests sent to OIC and one or more invoke (target) connections for requests sent from OIC.

Mapper and Data Structures

When opening the mapper for a request or response message in an integration, the data structures are automatically populated with the information pulled from the source and target connections.

Integration Flow and Timeouts

A legitimate strategy to mitigate timeout issues in synchronous integration flows is to change the implementation logic to invoke multiple fine-grained external API calls within a single loop.

Fault Handling

Adding a Try-Catch action to the integration flow and configuring it to catch and handle faults can mitigate runtime faults.
Implementing a scope fault handler to catch the runtime fault, and then using the Fault Return action providing mapped data for the custom fault, can return a custom business fault message to the client if processing fails.

Messaging Adapters

Both the Apache Kafka and OCI Streaming adapters support XML, JSON, and AVRO message formats.
The Apache Kafka Adapter can be configured to support transactions in case of a producer.

REST Adapter and Endpoint Configuration

Both standard and custom HTTP headers can be defined for both the request and the response using the REST Adapter Endpoint Configuration wizard.
File attachments can be accepted as a request option for the trigger interface.

OIC Service Roles

The ServiceInvoker role does not have permission to run an OIC Integration.

OIC Packages

Packages can be imported directly from the Oracle Marketplace.
Packages cannot be locked to deny other users access to integrations.

Performance Optimization

Analyzing performance metrics, identifying bottlenecks, and optimizing the integration accordingly can help improve integration performance.

Integration Export and Import

Imported integrations cannot be immediately activated if their dependent connection resources are not already present in the target OIC environment.
Exported integrations include all their dependent connection resource information except URLs and credentials.

Security and Authentication

Configuring the REST adapter with a Basic Authentication or OAuth 2.0 security policy and providing the required credentials can ensure that only authorized clients can access the integration.

SOAP and Advantages

SOAP is platform independent and programming language independent.
SOAP typically leverages XML-based payloads to communicate between two client machines across any modern network.
SOAP clients can easily hold stateful references to remote server-side SOAP objects.
