What action depicts configuring the IBM Watson Discovery service collection?

The action that accurately represents configuring the IBM Watson Discovery service collection is switching from a default configuration to a custom configuration using uploaded personal data.

In IBM Watson Discovery, configuring a collection typically involves customizing the setup to suit specific needs or use cases. This can include defining how the service should interact with the data that is being ingested, which might involve using uploaded personal data to inform the service about the domain it will operate within. This allows the service to deliver more relevant insights tailored to the unique context of the data provided.

The other options describe important steps in the overall process of utilizing IBM Watson Discovery but do not specifically represent the act of configuration itself. Converting, enriching, and normalizing data refers to preprocessing stages that prepare the data for ingestion rather than configuring the service. Testing query methods focuses on evaluating the search and retrieval functionalities, while determining resource allocation involves infrastructure planning, which is not primarily about configuring the service but rather about ensuring that the environment can support it.
