Question 1

During a SOC handoff review at Lucerne Publishing, the Tier 2 analyst must choose the table that contains the event family required by the hunting question. Which action most directly satisfies the requirement for the research subscription, response wave 1? The design priority is to retain evidence for follow-up analysis.

Select the Microsoft Defender XDR or Sentinel table whose schema contains the event type needed for the hunt
Use Microsoft Defender XDR threat analytics to understand the active threat, affected products, exposure, and recommended mitigations
Create the Microsoft Sentinel hunting query and monitor its results for recurring or emerging suspicious activity
Write or refine the KQL query so it filters, correlates, summarizes, or joins the security data needed to expose the suspected threat pattern
Create or manage a Summary rule that materializes the required aggregated data into a summary table

Correct answer: A

Why: Effective KQL hunting starts with the correct table because device, identity, email, cloud, and other event families are stored in different schemas. This directly addresses the requirement: choose the table that contains the event family required by the hunting question.

Write or refine the KQL query so it filters, correlates, summarizes, or joins the security data needed to expose the suspected threat pattern
Create or use the hunting graph to visualize connected entities and assess the incident blast radius
Create or manage the Microsoft Sentinel Data Lake KQL job for the required large-scale or historical processing task
Use Microsoft Defender XDR threat analytics to understand the active threat, affected products, exposure, and recommended mitigations
Create or manage a Summary rule that materializes the required aggregated data into a summary table

Correct answer: A

Option review:

B: Hunting graphs help analysts reason about entity relationships and visualize how an attack may have spread across connected assets. It can be appropriate in another security-operations scenario, but it does not most directly address this requirement: use KQL operators to isolate and correlate the activity that represents the suspected threat.

D: Threat analytics provides curated intelligence and organizational exposure context so analysts can understand relevant campaigns and prioritize mitigation. It can be appropriate in another security-operations scenario, but it does not most directly address this requirement: use KQL operators to isolate and correlate the activity that represents the suspected threat.

E: Summary rules pre-aggregate selected data into tables that can improve query performance and make recurring analytical patterns easier to query. It can be appropriate in another security-operations scenario, but it does not most directly address this requirement: use KQL operators to isolate and correlate the activity that represents the suspected threat.
