Shown solved, with the whole explanation open: this is what every question here carries.

6-1Threat Hunting and Remediation

An Enterprise Security upgrade brings in the Machine Learning Toolkit as the model generation package. What does it take over from, and why?

Correlation searches, for accuracyCorrelation searches remain the detection mechanism.
Extreme Search, for better scaleCorrect · your answerCorrect.
The risk framework, for speedThe risk framework is unrelated to model generation.
Data model acceleration, for costAcceleration is a search performance feature.

Correct.

Concept

Statistical modeling earns its place when the normal shape of activity is not known in advance. A threshold somebody typed in only works until the environment changes.

Why B

Splunk documents that MLTK is replacing Extreme Search as a model generation package, scaling at larger volume and identifying more abnormal events through its models.

Source

The Splunk Machine Learning Toolkit (MLTK) is replacing Extreme Search (XS) as a model generation package in Enterprise Security (ES). MLTK can scale at larger volume and also can identify more abnormal events through its models.
