The correct answer is A because after a successful POST to a Phantom REST endpoint to create a new

object, the result returned is the new object ID. The object ID is a unique identifier for each object in

Phantom, such as a container, an artifact, an action, or a playbook. The object ID can be used to

retrieve, update, or delete the object using the Phantom REST API. The answer B is incorrect because

after a successful POST to a Phantom REST endpoint to create a new object, the result returned is not

the new object name, which is a human-readable name for the object. The object name can be used

to search for the object using the Phantom web interface. The answer C is incorrect because after a

successful POST to a Phantom REST endpoint to create a new object, the result returned is not the

full CEF name, which is a standard format for event data. The full CEF name can be used to access the

CEF fields of an artifact using the Phantom REST API. The answer D is incorrect because after a

successful POST to a Phantom REST endpoint to create a new object, the result returned is not the

PostGres UUID, which is a unique identifier for each row in a PostGres database. The PostGres UUID

is not exposed to the Phantom REST API. Reference: Splunk SOAR REST API Guide, page 17. When a

POST request is made to a Phantom REST endpoint to create a new object, such as an event, artifact,

or container, the typical response includes the ID of the newly created object. This ID is a unique

identifier that can be used to reference the object within the system for future operations, such as

updating, querying, or deleting the object. The response does not usually include the full name or

other specific details of the object, as the ID is the most important piece of information needed

immediately after creation for reference purposes.
