Microsoft Security Operations Analyst Associate SC-200 Practice Question

ASIM supplies ready-made Kusto functions-also called parsers-that union the relevant tables from every connected data source and project the fields defined in the ASIM schema. For DNS investigations you call the imDns() parser (sometimes surfaced as _Im_Dns). This function brings together DNS events from sources such as Microsoft Defender for Endpoint, DNS analytics logs, and Sysmon, and standardizes them to the DNS activity schema, exposing fields like DnsQuery, DnsResponseName, SrcIpAddr, and Computer. Using generic tables like SecurityEvent or DeviceNetworkEvents directly would miss data from other sources, and the UnifiedTables function is intended for UEBA enrichment, not ASIM normalization. Therefore, starting the query with imDns() is the correct approach.
