Microsoft Azure Data Fundamentals DP-900 Practice Question

You are reviewing a set of application log files that are saved as JSON documents. Each document uses key-value pairs to describe events, but some events have additional keys that others do not. Which statement best explains why this data is considered semi-structured?

  • The documents contain tags or key-value pairs that provide a flexible, self-describing structure, so each record can vary in the attributes it stores.

  • The data is stored in fixed columns defined by a relational schema, and every record must match that schema exactly.

  • The documents can only be processed with image recognition algorithms because they lack any machine-readable structure.

  • The documents are stored as binary objects that have no inherent tags, making their meaning understandable only to humans.
