Which two structured analytics operations require an analytics profile?

The correct choice highlights that both Email Threading and name normalization require an analytics profile to function properly. An analytics profile is essential because it defines the parameters and configuration settings that guide how the structured analytics are processed.

Email Threading is a process that identifies relationships between emails, allowing users to visualize them as threads based on their timestamps and reply patterns. This operation relies on a well-defined analytics profile to accurately establish those relationships and present them coherently.

Name normalization is concerned with standardizing the ways names are represented in the data set, which also requires an analytics profile to apply relevant rules and formats consistently. This ensures that variations in name spelling, abbreviations, or different naming conventions are harmonized throughout the data, facilitating effective analysis.

The other options involve operations that may not necessitate an established analytics profile or may function without the nuanced data processing that a profile provides. For instance, document identification and attachment sorting focus more on structural aspects of documents rather than the systematic analysis governed by an analytics profile.
