SPLK-1001 Practice Test 4 — 10 Questions

Question 1

Which THREE of the following are capabilities of the rex command?

Accepted Answer

Extract fields using regex named groups.. The `rex` command can extract fields using regex named groups, where the group name becomes the field name and the matched value becomes the field value. This is a core capability of `rex` for field extraction in Splunk.

Answer

Perform case-insensitive extraction by default.

Answer

Set a default value for a field.

Question 2

A large enterprise uses Splunk to monitor 500+ servers. A search returns results slowly due to high data volume. Which best practice can improve performance when using the top command?

Accepted Answer

Add a limit to top, e.g., top limit=20. Adding a limit to the top command (e.g., top limit=20) restricts the number of results returned, reducing the computational load and memory usage. In high-volume environments, this directly improves search performance by limiting the aggregation work Splunk must perform across all 500+ servers.

Answer

Use the fields command to remove unnecessary fields

Answer

Use rare instead of top to reduce output

Answer

Apply the sort command before top

Question 3

A security analyst runs a search that returns many fields, most of which are not needed. Which command should be used to remove all fields except 'src_ip', 'dest_ip', and 'action'?

Accepted Answer

| fields + src_ip, dest_ip, action. The `fields` command with the `+` prefix explicitly keeps only the listed fields and removes all others from the search results. This is the correct way to retain only `src_ip`, `dest_ip`, and `action` while discarding the rest.

Answer

| rename src_ip as src, dest_ip as dest, action as act

Answer

| fields - src_ip, dest_ip, action

Answer

| table src_ip, dest_ip, action

Question 4

Refer to the exhibit. A user runs the search shown. The search returns results, but the user wants to use a data model to make future searches faster and more consistent. Which data model should the user select and what is the correct acceleration setting?

Accepted Answer

Use the CIM Web data model and accelerate the 'Web' dataset.. The search shown uses fields like `status`, `action`, `uri`, and `method`, which are standard fields in the CIM Web data model. Accelerating the 'Web' dataset pre-computes the relevant field extractions and aggregations, making future searches faster and more consistent without requiring the user to manually define field extractions or transformations.

Answer

Use the CIM Web data model and select 'Accelerate All Datasets' from the settings.

Answer

Create a new data model called 'Access' and enable acceleration on root events.

Answer

Use the built-in 'Searches' data model to pre-compute the count and status fields.

Question 5

Which TWO actions increase the performance of a dashboard in Splunk? (Choose two.)

Accepted Answer

Use scheduled reports as base searches. Scheduled reports as base searches pre-compute and cache results, reducing the real-time query load on the indexers when the dashboard loads. This shifts expensive computation to off-peak times, improving dashboard rendering speed.

Answer

Add a large number of drilldowns

Answer

Use real-time searches

Answer

Add multiple time range pickers to the dashboard

Question 6

An administrator notices that a data model is not appearing in the Pivot interface. What is a possible reason?

Accepted Answer

The data model is not shared with the user's role.. The Pivot interface only displays data models that have been explicitly shared with the user's role via permissions. If the data model is not shared, it will not appear in the Pivot editor, regardless of its internal validity or acceleration status. This is a core access control mechanism in Splunk.

Answer

The data model acceleration is disabled.

Answer

The data model contains errors in field definitions.

Answer

The data model has no root datasets.

Question 7

A user has a search that produces a chart of error counts by host. They want to add a calculated field 'error_rate' as errors per million events. Which approach is correct?

Accepted Answer

Use eventstats to get total counts, then eval to compute rate, then chart. It uses `eventstats` to compute the total count of events per host across the entire result set, then `eval` to calculate the error rate as (error_count / total_count) * 1,000,000, and finally `chart` to display the results. This two-step approach ensures the total count is available for each row before the rate calculation, which is necessary because `chart` alone cannot reference a field computed in the same command.

Answer

Use chart eval(error_count/total_count) by host

Answer

Use stats to compute error_rate directly: stats avg(error_rate) by host

Answer

Use the lookup command to apply a calculated field

Question 8

Which THREE of the following are best practices when designing data models in Splunk?

Accepted Answer

Enable acceleration only on data models that are used frequently.. Enabling acceleration on all data models consumes significant disk space and processing overhead. Acceleration should be reserved for data models that are queried frequently to optimize resource usage and query performance. Splunk's acceleration feature pre-computes summaries for the root events and child objects, which is only beneficial when the data model is regularly accessed.

Answer

Design the data model based on the most common reports to ensure quick results.

Answer

Include every possible field in the data model to avoid future modifications.

Question 9

A security analyst runs a search for failed logins and wants to display the source IP address, username, and count of failures. However, the field 'src_ip' is not showing in the field picker. Which of the following is the most likely reason?

Accepted Answer

The field is not extracted by default from the data source.. In Splunk, fields like 'src_ip' are not automatically extracted from raw event data unless the data source has a predefined source type that includes field extraction rules (e.g., via a technology add-on or custom regex). If the field does not appear in the field picker, it typically means the search has not extracted it from the raw events, so the analyst must use commands like `rex` or `extract` to parse it.

Answer

The field has no values in the results.

Answer

The user does not have permission to view the field.

Answer

The field name contains a typo.

Question 10

Match each index type to its purpose.

Accepted Answer

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

Main index: Stores pre-computed results.

Answer

Summary index: Stores all indexed events by default.
