Splunk Core Certified Power User Practice Test

Answer choices

1. A. Use `stats` grouped by `session_id` to calculate `count`, `earliest(_time)`, `latest(_time)`, and `avg(response_ms)`.
2. B. Use `transaction` because it is always faster for any grouping by an identifier. The proposed advantage is that transaction boundaries would remain intact while the aggregation is performed over the same logical activity.
3. C. Use `join` because statistical commands cannot calculate per-session durations.
4. D. Use `dedup session_id` before calculating statistics so each session has one event.

Wrong-answer review

• B. Use `transaction` because it is always faster for any grouping by an identifier. The proposed advantage is that transaction boundaries would remain intact while the aggregation is performed over the same logical activity.: `transaction` has additional memory and grouping work and is not automatically faster for simple field-based aggregation.
• C. Use `join` because statistical commands cannot calculate per-session durations.: `stats` can calculate min/max times and grouped metrics without a join.
• D. Use `dedup session_id` before calculating statistics so each session has one event.: Deduplication would discard events needed to determine duration and other statistics.

Answer choices

1. A. `index=api | timechart count BY status`
2. B. `index=api | chart count OVER service BY status`
3. C. `index=api | stats count BY service status` because `stats` will format the grouped service/status counts into the same two-dimensional chart matrix automatically.
4. D. `index=api | chart count BY status`

Answer choices

1. A. `| fillnull owner,team value="unknown"`
2. B. `| fillnull(owner,team,"unknown")`
3. C. `| fillnull value="unknown" owner team`
4. D. `| fields owner team | nullvalue="unknown"`

Answer choices

1. A. CIM normalization is normally performed at search time with knowledge objects that map source data to common fields and tags.
2. B. Rewrite each event into CIM field names at index time before storing it; data-model datasets cannot consume search-time aliases, lookups, or calculated fields.
3. C. CIM works only when all source systems emit the standard CIM field names natively.
4. D. CIM is an ingest-time parsing engine that replaces props.conf and transforms.conf.

Answer choices

1. A. The command fails because at least one field name is mandatory.
2. B. Only the `_raw` field is evaluated when the field list is omitted.
3. C. A new field literally named `N/A` is created for every event.
4. D. The replacement is applied to null values in all fields that exist in the result set.

Answer choices

1. A. `` `pair_filter(host,web01)` ``
2. B. `` `pair_filter(field=host,value=web01)` ``
3. C. `$pair_filter$host$web01$`
4. D. `| pair_filter host web01`

Answer choices

1. A. Nothing changes; delimiter field names are bound to semantic values rather than column positions.
2. B. Only `_time` can shift; user-defined delimiter fields always stay aligned automatically.
3. C. Fields after the inserted column can shift positions and be assigned the wrong names, so the extraction must be retested and updated.
4. D. Accept the extra delimiter column because Field Extractor automatically converts unexpected columns into tags instead of adding another extracted field.

Answer choices

1. A. Leaves the value completely unescaped in every case.
2. B. Converts the value to Base64 before adding it to the URI.
3. C. URL-encodes the substituted field value.
4. D. Drops punctuation and spaces before sending the request.

Answer choices

1. A. Increase the event type's color priority; color controls which events are included.
2. B. Refine the defining simple search so it returns exactly the intended event category before saving or deploying the event type.
3. C. Add a calculated field named `eventtype` to override the broad matches.
4. D. Move the qualifying search into a POST workflow action; events for which the action executes are then persisted as members of the event type.

Answer choices

1. A. Replace the entire pattern with `(?<path>.*)` so every event produces a value.
2. B. Remove the field label from the regex and capture the first token on every line.
3. C. Keep the stable field label and make only the expected whitespace flexible, for example `path=\s*"(?<path>[^"]+)"`.
4. D. Make the capture optional with `.*?` before and after it, without keeping any stable surrounding text.
