Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Main index: Stores all indexed events by default.
The main index stores all default events. Summary indexes accelerate searching by storing pre-computed results. Metrics indexes handle numeric time-series data, and internal indexes contain Splunk operational logs. Common confusions involve mixing up the main and summary indexes.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Main index: Stores all indexed events by default.
Why this is correct
The main index is the default index where all incoming events are stored unless routed elsewhere.
Summary index: Stores pre-computed results to speed up searches.
Why this is correct
Summary indexes hold pre-calculated results from scheduled searches, making searches over time faster.
Metrics index: Stores numeric time-series data for performance monitoring.
Why this is correct
Metrics indexes are designed for storing numeric data points, such as CPU usage, for efficient analysis.
Internal index: Stores Splunk internal logs.
Why this is correct
The internal index contains Splunk's own logs, such as errors and warnings.
Main index: Stores pre-computed results.
Why it's wrong here
Incorrect — this describes the summary index, not the main index.
Summary index: Stores all indexed events by default.
Why it's wrong here
