The correct answer is C because the last step of the 12A2 design methodology is to list the outputs of the playbook design. The outputs are the expected results or outcomes of the playbook execution, such as sending an email, creating a ticket, blocking an IP, etc. The outputs should be aligned with the objectives and goals of the playbook. See Splunk SOAR Certified Automation Developer for more details.
The 12A2 design methodology in the context of Splunk SOAR (formerly Phantom) refers to a structured approach to developing playbooks. The last step in this methodology focuses on defining the outputs of the playbook design. This step is crucial as it outlines what the expected results or actions the playbook should achieve upon its completion. These outputs can vary widely, from sending notifications, creating tickets, updating statuses, to generating reports. Defining the outputs is essential for understanding the playbook's impact on the security operation workflows and how it contributes to resolving security incidents or automating tasks.

The correct REST Django expression to retrieve events with the label "notable" that are in the "new" status is using the container endpoint, as containers are used to store events and associated data in Splunk SOAR. The expression correctly filters the events by label (_filter_label="notable") and status (_filter_status="new"), ensuring only notable events that are still in the "new" status are selected.
A and D reference the wrong endpoints (event and notable respectively), which do not align with the container-based model used in Splunk SOAR for storing and filtering events.
B is incorrect due to the use of _filter_name instead of _filter_label, which is not a valid filter in this context.

Splunk Phantom supports different types of backups to safeguard data. Full backups create a complete copy of the current state of the system, while incremental backups only save the changes made since the last backup.
This approach allows for efficient use of storage space and faster backups after the initial full backup. Delta backups, which would save changes since the last full or incremental backup, are not a standard part of Phantom's backup capabilities according to available documentation. Therefore, the complete list of backups supported by Phantom would be Full and Incremental backups.

Explanation
The correct answer is A because the _filter parameter is used to filter the results based on a field value, and the icontain operator is used to perform a case-insensitive substring match. The filePath field is part of the Common Event Format (CEF) standard, and the cef_ prefix is used to access CEF fields in the REST API. The answer B is incorrect because it uses the wrong syntax for the REST API. The answer C is incorrect because it uses the wrong endpoint (result instead of artifact) and the wrong syntax for the REST API. The answer D is incorrect because it uses the wrong syntax for the REST API and the wrong spelling for the icontains operator.

Explanation
The correct answer is C because without customizing container status within Phantom, the three types of status for a container are New, Open, and Resolved. A container is a data object that represents an event or incident that needs to be investigated or remediated. A container has a status attribute that indicates its current state. The default values for the status attribute are New, Open, and Resolved. New means that the container has been created but not yet processed. Open means that the container is being processed by a playbook or a user. Resolved means that the container has been processed and closed. You can customize the container status values in the Phantom UI by going to Administration > Product Settings > Container Status. See Splunk SOAR Documentation for more details.
