SPLK-1004 Practice Test 21 — 15 Questions

Question 1

A Splunk administrator is reviewing the performance of several data models and wants to optimize them for acceleration. The administrator plans to make changes to the data models to improve acceleration efficiency. Which of the following actions would likely improve data model acceleration performance? (Choose two.)

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Reducing the number of fields in the data model by removing unnecessary fields.. Reducing the number of fields and adding constraints both reduce the volume of data that must be summarized during acceleration. Fewer fields mean less data to store and process, while constraints filter out events that do not need to be accelerated. These actions lead to smaller summary files and faster acceleration times.

Answer

Enabling acceleration on all data models simultaneously to share resources.

Answer

Increasing the acceleration summary range to cover all time.

Answer

Using a shorter acceleration interval to refresh summaries more frequently.

Question 2

A Splunk power user is creating a workflow action of type 'Search' that will run a secondary search when an analyst clicks a field value in the results. The user wants the secondary search to open in a new browser tab and to pass the clicked field value as an argument to the search. Which configuration should the user apply?

Accepted Answer

Set the 'Search string' field to the secondary search using `$field_value$` and enable 'Open in new window'.. A workflow action of type 'Search' requires the secondary search to be defined in the 'Search string' field. The clicked field value is passed using a token such as `$field_value$`. To make the search open in a new browser tab, the 'Open in new window' option must be enabled. This configuration satisfies both the argument passing and the new-tab requirement.

Answer

Set the 'Link URI' field to a URL that includes the search string and enable 'Open in new window'.

Answer

Set the 'Search string' field to the secondary search using `$field_value$` and enable 'Run in background'.

Answer

Set the 'Link URI' field to the search string and enable 'Open in new window'.

Question 3

Which command sorts results by a field in descending order?

Accepted Answer

sort -field. In Splunk SPL, prefixing a field name with a minus sign in the sort command sorts that field in descending order, so 'sort -field' is correct. Ascending order is the default and uses no prefix, while a plus sign explicitly requests ascending. This is a fundamental SPL syntax rule tested on SPLK-1004.

Answer

sort desc(field)

Answer

sort field=desc

Answer

sort field

Question 4

You want an alert to run every Monday at 8 AM. How should you configure the schedule?

Accepted Answer

Use a cron expression of 0 8 * * 1.. To schedule an alert for every Monday at 8 AM, you need a cron expression that specifies minute 0, hour 8, any day of month, any month, and day of week 1 (Monday). The expression '0 8 * * 1' exactly matches this schedule. Splunk's alert scheduler uses cron expressions for precise timing.

Answer

Run every 1 hour.

Answer

Use the Weekly setting.

Answer

Use the Daily setting.

Question 5

A Splunk user has a search that returns events with a field named status_code containing values like 200, 404, and 500. The user wants to create a new field named status_category that contains the text Success for 200, Client Error for 4xx codes, and Server Error for 5xx codes, without removing the original status_code field. Which eval expression accomplishes this?

Accepted Answer

eval status_category=case(status_code==200, "Success", status_code>=400 AND status_code<500, "Client Error", status_code>=500, "Server Error"). To map multiple numeric ranges to text labels, the case function is appropriate because it evaluates a list of condition-value pairs in order and returns the value for the first true condition. This allows 200 to map to Success, 4xx to Client Error, and 5xx to Server Error in a single eval, while the original status_code field remains available.

Answer

eval status_category=if(status_code==200, "Success", "Error")

Answer

eval status_category=replace(status_code, "200", "Success")

Answer

eval status_category=coalesce(status_code, "Success", "Client Error", "Server Error")

Question 6

A user complains that a calculated field is not showing up. Which of the following is the best first step to troubleshoot?

Accepted Answer

Check if the field is in the 'Selected Fields' or 'Interesting Fields' list.. When a calculated field (defined via props.conf EVAL- or a calculated field in the UI) does not appear, the most likely cause is that the field was not extracted or the search did not return it in the current result set. The fastest, least invasive first step is to check whether the field appears in the 'Selected Fields' or 'Interesting Fields' sidebar, since Splunk only lists fields that were actually extracted in the returned events. This confirms whether the field exists at all before escalating to configuration or infrastructure changes.

Answer

Restart the Splunk service.

Answer

Change the indexer's cluster master.

Answer

Delete the index and re-ingest the data.

Question 7

An engineer defines a calculated field in Settings > Fields with the expression `eval total_bytes = upload_bytes + download_bytes` scoped to sourcetype `netflow`. Searches confirm the field appears. Later, a new field named `total_bytes` is extracted from the raw event by a search-time extraction. What is the resulting behavior for the calculated field?

Accepted Answer

The extracted total_bytes value takes precedence, and the calculated field is not applied.. Search-time extraction precedes calculated field evaluation, and calculated fields are applied only when their target field is absent. Once the extraction supplies total_bytes, the calculated expression is not executed for those events, so the extracted value is the one returned by searches.

Answer

The calculated field overwrites the extracted value because calculated fields run last.

Answer

The calculated field continues to apply and silently replaces the extraction at index time.

Answer

Both values are retained, and the field becomes multivalued with two entries.

Question 8

Where can users find a list of all currently available workflow actions?

Accepted Answer

Settings > Fields > Workflow actions. Workflow actions are managed under Settings > Fields > Workflow actions, where administrators can view, create, edit, and enable/disable all workflow actions available in the Splunk instance. This is the central management page for both GET and POST workflow actions, and it lists every action along with its app context and permissions.

Answer

Settings > Search

Answer

Settings > User interface

Answer

Settings > Data inputs

Question 9

A power user is optimizing a dashboard that uses a base search with post-process searches. The base search returns events with many fields, but only a few fields are used by the post-process searches. Which action will most effectively reduce the amount of data transferred from the base search to the post-process searches?

Accepted Answer

Add `| fields field1, field2, field3` to the base search, listing only the required fields.. To minimize data transferred from the base search to post-process searches, you should include only the fields that are actually used. Using the fields command to explicitly list required fields removes all other fields, including _raw, thereby reducing the size of the result set. This is more effective than just removing _raw when many other unused fields exist.

Answer

Use `| table field1, field2, field3` in the base search.

Answer

Add `| fields - _raw` to the base search.

Answer

Add `| dedup` to the base search to remove duplicate events.

Question 10

A dashboard uses a base search with post-process searches. Users report that some panels show incorrect results after the base search completes. You need to troubleshoot the issue. Which two actions should you take to identify the cause? (Choose two.)

Accepted Answer

Verify that the base search includes all fields required by the post-process searches.. Incorrect results in post-process panels often stem from missing fields or incompatible commands. The base search must provide all fields that post-process searches need. Also, if the base search removes _raw, post-process searches cannot use commands that depend on _raw. Checking these two aspects will resolve many common issues with post-process searches.

Answer

Ensure that the base search is a transforming search and does not return raw events.

Answer

Increase the max result count for the base search to prevent truncation.

Answer

Confirm that the base search time range is set to 'All time' to ensure all events are included.

Question 11

A Splunk power user is building a dashboard that must display the total revenue per product category. The raw events contain a field named `price` (numeric) and a field named `quantity` (numeric). The user wants to create a calculated field named `revenue` that multiplies these two fields, and ensure it is available for all future searches without modifying the raw data. Which of the following is the correct method to achieve this?

Accepted Answer

Define a calculated field in the `props.conf` file using the `EVAL-revenue` setting that evaluates `price * quantity`.. Calculated fields are defined in `props.conf` using the `EVAL-<fieldname>` syntax. They compute new fields at search time based on existing fields, without modifying raw data. This makes them ideal for creating derived fields like `revenue` that should be available across all searches. The other options either do not persist, are not designed for calculations, or are impractical for dynamic computations.

Answer

Use the `eval` command in each search to create the `revenue` field, and save the search as a report to ensure it is always available.

Answer

Create a lookup definition that maps each combination of `price` and `quantity` to a precomputed `revenue` value, and configure automatic lookup.

Answer

Create a field extraction using the Interactive Field Extractor (IFX) and define a regular expression to capture the product of price and quantity.

Question 12

A Splunk power user has created a macro named `convert_time` that accepts one argument, a time field, and returns the time in epoch format. The user wants to use this macro in a search and also wants to ensure that if the macro is called without an argument, it uses a default field named `_time`. Which approach should be used?

Accepted Answer

Define two macros: one with one argument and one with zero arguments that calls the one-argument macro with `_time`.. Splunk macros do not support default values for arguments. To achieve a default behavior, the best approach is to create two macros: one that accepts an argument and performs the conversion, and another that takes no arguments and calls the first macro with the default field `_time`. This allows users to call the zero-argument macro when they want the default, or the one-argument macro when they need to specify a different field. This pattern is widely used in Splunk to simulate optional parameters.

Answer

Define the macro with one argument and use the `eval` command to check if the argument is null, then set it to `_time`.

Answer

Define the macro with one argument and instruct users to always pass `_time` if they want to use the default.

Answer

Define the macro with one argument and set the argument's default value in the macro's permissions settings.

Question 13

An analyst is building an alert that must fire only when the count of events from a search exceeds a threshold, and the alert must suppress duplicate notifications for the same host for one hour. The search is `index=firewall action=blocked | stats count by src_ip`. Which TWO alert configuration elements are required to satisfy these requirements? (Choose two.)

Accepted Answer

Configure alert suppression with a suppression field of `src_ip` and a suppression period of 1 hour. The stats command produces one row per source IP with a count field, so the threshold must be applied to that field through a where clause or a trigger condition referencing count. Duplicate notifications for the same host are prevented by configuring alert suppression keyed on `src_ip` for a one-hour window, which is the documented mechanism for per-field deduplication.

Answer

Set the alert to run in real-time with a sliding window of one hour

Answer

Set the trigger condition to "Number of Results" greater than 0 with a custom threshold on the stats output

Answer

Enable throttling by setting the alert's expiration to one hour without specifying a suppression field

Question 14

A Splunk power user is creating a macro that will be used in a search. The macro definition includes a search command that is not permitted by the user's role. What happens when the user attempts to run a search that calls this macro?

Accepted Answer

The macro is expanded, but the search fails with an error indicating that the command is not permitted.. When a macro is used in a search, it is expanded inline, and the resulting search is executed with the permissions of the user. If the macro contains a command that the user's role does not permit, the search will fail with a permission error. Macros do not bypass role-based access controls. Therefore, the search will not run successfully.

Answer

The macro is expanded, but the disallowed command is replaced with a null command.

Answer

The macro is skipped, and the search continues without the macro's content.

Answer

The macro is executed with elevated privileges, allowing the command to run.

Question 15

A Splunk administrator is reviewing an accelerated data model for network traffic. They notice that the acceleration summary contains only events from the last 7 days, but the data model is configured to retain 30 days of summaries. The administrator checks the acceleration settings and sees that the 'Acceleration time range' is set to 'All time'. What is the most likely reason for the discrepancy?

Accepted Answer

The data model's acceleration is using a summary index that has a retention policy of 7 days.. Data model acceleration stores summarized results in a summary index. The retention of these summaries is governed by the retention policy of that index, not by the acceleration time range. If the summary index is configured to retain only 7 days of data, the acceleration summaries will only cover the last 7 days, regardless of the acceleration time range setting. Checking the summary index's retention policy resolves the discrepancy.

Answer

The data model's acceleration is not enabled for the entire time range due to a permissions issue.

Answer

The data model's acceleration is configured with a summary range that only covers the last 7 days.

Answer

The data model's acceleration is limited by the search head's available disk space, causing older summaries to be deleted.
