Understanding Reference Data Collections in QRadar: In IBM QRadar, reference data collections are used to store data that can be reused across various rules, searches, and reports. Each type of reference data collection has a specific use case and structure.

Types of Reference Data Collections:

Reference Map: Stores key-value pairs where each key is unique and maps to a specific value.

Reference List: Stores a list of values without any keys.

Reference Table: Stores multiple key-value pairs where each key can have multiple values.

Reference Set: Stores a set of unique values without any keys.

Use Case for Reference Map: When you need to correlate a unique key to a specific value, a reference map is the appropriate data structure. It allows for efficient lookups and associations between keys and their corresponding values.

Reference Confirmation: According to IBM QRadar documentation, a reference map is explicitly designed to correlate unique keys to values, making it the correct choice for such requirements.
