   What is the primary purpose of Cortex Data Models (XDMs) in the XSIAM data pipeline?

   • ATo normalize data from diverse sources into a standardized schema for consistent analytics
   • BTo store raw logs in their original format for long-term archival
   • CTo replace the need for any data ingestion or parsing configurations in XSIAM
   • DTo encrypt all data at rest and in transit within the XSIAM platform

   What is a key advantage of using XDM-normalized data over raw data for security analytics?

   • AXDM data is stored in a compressed format that uses less storage space
   • BXDM data provides a consistent structure that allows for efficient cross-source correlation
   • CXDM data is always complete and contains every field from the original log
   • DXDM data is always accurate and free of parsing errors

   What happens to a source-specific field like 'src_ip' from a firewall log when it is ingested into XSIAM?

   • AIt is converted to a string and stored in a generic 'metadata' field
   • BIt is stored as 'src_ip' in the XDM schema without any changes
   • CIt is mapped to the standardized XDM field 'source.ip'
   • DIt is discarded because XSIAM only keeps standardized fields
