SPLK-1001 Practice Test 23 — 15 Questions

Question 1

A search returns many events but the 'status' field is missing from some events. The admin wants to set a default value of 'unknown' when the field is absent. Which command should be used?

Accepted Answer

fillnull value=unknown status. The `fillnull` command explicitly sets a default value for specified fields when they are null or missing in search results. In this scenario, `fillnull value=unknown status` replaces all null or absent 'status' field values with 'unknown', ensuring consistency across events. This command is designed specifically for handling missing field values in Splunk, unlike `eval` or `default` which operate differently.

Answer

eval status=coalesce(status, "unknown")

Answer

default status=unknown

Answer

replace status with "unknown"

Question 2

A user runs a search but sees zero results. What is the most common cause for this?

Accepted Answer

The time range picker is set to a period with no data.. The most common cause for zero search results in Splunk is that the time range picker is set to a time period that contains no indexed data. By default, Splunk restricts searches to the selected time range, and if no events were indexed during that window, the search returns zero results regardless of the query syntax or index selection.

Answer

The search did not specify an index.

Answer

The source type is incorrect.

Answer

The search syntax contains a typo.

Question 3

A user wants to create a dashboard panel that refreshes automatically every 60 seconds. Which setting must be configured in the panel's edit mode?

Accepted Answer

Set the Refresh Interval to 60 seconds. The dashboard panel's edit mode includes a 'Refresh Interval' setting that allows you to specify an automatic refresh period in seconds. Setting this to 60 causes the panel to re-run its underlying search and update the visualization every 60 seconds without manual intervention.

Answer

Add | delay 60 to the search

Answer

Schedule the search to run every 60 seconds

Answer

Set the Time Range to Last 60 seconds

Question 4

Refer to the exhibit. What does the log entry indicate about the search job?

Accepted Answer

The search job hit the time limit and returned partial results.. The log entry shows 'Search job completed with partial results' and 'time limit reached', which directly indicates that the search job hit the configured time limit and returned whatever results were available up to that point. This is a standard Splunk behavior when the `maxtime` setting or the search's time window is exceeded, and the job does not fail but returns partial data.

Answer

The search job was cancelled by the user.

Answer

The search job failed due to permission issues.

Answer

The search job found no results.

Question 5

In Splunk Web, which option allows a user to save a search result as a report that can be added to a dashboard later?

Accepted Answer

Click 'Save As' and select 'Report'.. In Splunk Web, the 'Save As' menu provides a direct option to save a search result as a report. A report is a saved search that can be reused, scheduled, and added to dashboards as a dashboard panel later. This workflow is the standard method for creating a persistent search artifact that can be visualized on a dashboard.

Answer

Click 'Save As' and select 'Search'.

Answer

Click 'Save As' and select 'Alert'.

Answer

Click 'Save As' and select 'Dashboard Panel'.

Question 6

A team has a lookup table 'app_errors.csv' that includes a field 'error_code'. They want to automatically join error descriptions from 'error_codes.csv' on 'error_code' every time they search a sourcetype. What is the best way to achieve this?

Accepted Answer

Set up an automatic lookup in props.conf for the sourcetype. An automatic lookup in props.conf allows you to define a lookup that runs automatically on every search for a given sourcetype, without requiring manual invocation. This configuration joins the 'error_code' field from the search results with the 'error_codes.csv' lookup table, appending the description field to every event of that sourcetype. It is the most efficient and consistent method for automatically enriching data at search time.

Answer

Use an eval statement with if() to assign description

Answer

Configure field aliases to rename 'error_code'

Answer

Use the lookup command in every search

Question 7

Which three of the following are valid ways to navigate and interact with data in the Splunk Web interface? (Choose three.)

Accepted Answer

Configuring data inputs through the Settings menu to bring data into Splunk. The Search & Reporting app is the primary interface for running searches and viewing results, making it a valid way to interact with data. Configuring data inputs via the Settings menu is a standard method for bringing data into Splunk. The Dashboards feature allows users to create visualizations from saved searches, which is a core navigation and interaction capability in the Splunk Web interface.

Answer

Creating a new indexer via the Settings menu to store incoming data

Answer

Installing new Splunk licenses through the Splunk Home page

Answer

Editing Splunk configuration files directly from the web interface without command line access

Question 8

A data model 'Network_Traffic' currently has a single root dataset 'Traffic'. The administrator wants to add a child dataset 'Firewall_Logs' that only contains events from sourcetype=firewall. The admin also wants 'Firewall_Logs' to inherit all fields from 'Traffic'. Which approach should they follow?

Accepted Answer

Create 'Firewall_Logs' as a child of 'Traffic' and add a constraint: sourcetype=firewall.. In Splunk data models, child datasets inherit all fields from their parent root dataset automatically. By creating 'Firewall_Logs' as a child of 'Traffic' and adding a constraint of `sourcetype=firewall`, the child dataset will only contain events matching that sourcetype while inheriting all field definitions from the parent 'Traffic' dataset. Constraints in data models filter events at search time, ensuring only relevant events appear in the child dataset.

Answer

Create 'Firewall_Logs' as a separate root dataset and add a constraint: sourcetype=firewall.

Answer

Use the 'merge' function to combine the datasets.

Answer

Create 'Firewall_Logs' as a child of 'Traffic' and add a filter: sourcetype=firewall.

Question 9

Refer to the exhibit. An analyst receives this error when running a tstats search. Which of the following is the most likely cause?

Accepted Answer

The data model name or dataset is misspelled.. The error message in the exhibit indicates that the tstats command cannot find the specified data model or dataset. This typically occurs when the name provided in the 'datamodel=' argument does not match any existing accelerated data model or dataset in Splunk. Option B is correct because a misspelling or incorrect casing in the data model name or dataset is the most common cause of this specific error.

Answer

The syntax should use 'datamodel' as a separate argument without equals sign.

Answer

The analyst does not have permission to use tstats.

Answer

The data model is not accelerated.

Question 10

An analyst wants to remove duplicate events based on the 'user' field, keeping only the first occurrence. Which command should be used?

Accepted Answer

| dedup user. The `dedup` command in Splunk removes duplicate events based on specified fields, keeping only the first occurrence by default. Since the analyst wants to remove duplicates based on the 'user' field and retain the first event, `| dedup user` is the correct command.

Answer

| sort -user

Answer

| uniq user

Answer

| fields user

Question 11

A user creates a calculated field that extracts the domain from email addresses using the expression `| rex field=email "(?P<domain>@\w+\.\w+)"`. However, the calculated field does not appear in search results. What is the most likely reason?

Accepted Answer

Calculated fields must be enabled in props.conf with REPORT clauses.. Calculated fields in Splunk require explicit configuration in props.conf using a REPORT clause to define the extraction. Without this configuration, the calculated field is not available for use in searches, even if the extraction expression is valid. The user's calculated field definition is missing the necessary props.conf setup, so it never gets applied.

Answer

Calculated fields are only applied at search time, not index time.

Answer

The field extraction is incorrect.

Answer

Calculated fields must be used with the `eval` command.

Question 12

Refer to the exhibit. An administrator runs this command. What is the effect?

Accepted Answer

Returns the contents of the CSV file as search results.. The command `inputlookup` reads the contents of the specified CSV file and returns them as search results. It does not create a lookup definition or persistent data input; it is a one-time import for the current search.

Answer

Creates a lookup definition named my_lookup using the file my_lookup.csv.

Answer

Creates a lookup definition and automatically populates it with the file contents.

Answer

Adds the file to the monitor directory.

Question 13

A user wants to create a report that shows the average response time for each web endpoint over the past week. The data has fields: endpoint, response_time. Which search correctly calculates the average?

Accepted Answer

... | stats avg(response_time) by endpoint. The `stats avg(response_time) by endpoint` command calculates the average (mean) of the response_time field for each unique endpoint value. This directly meets the requirement of showing average response time per web endpoint over the past week, assuming the time range is set in the search bar or via an earliest/latest constraint.

Answer

... | stats mean(response_time) by endpoint

Answer

... | stats avg(response_time) by _time

Answer

... | eval avg=sum(response_time)/count | stats values(avg) by endpoint

Question 14

A Splunk administrator is troubleshooting a time-based lookup that is supposed to match events to a lookup table that changes over time. The lookup is defined with time_field 'start_time' and time_format '%Y-%m-%d %H:%M:%S'. Which THREE conditions must be met for the time-based lookup to correctly match an event to a single row in the lookup table? (Choose three.)

Accepted Answer

The lookup definition must specify the time format used in the time_field column. The lookup definition must specify the time format used in the time_field column so that Splunk can correctly parse the time values in the lookup table. Without this format specification, Splunk cannot interpret the timestamps and the time-based matching will fail.

Answer

The lookup table must have exactly one row per unique time value

Answer

The lookup must be defined as an automatic lookup in props.conf

Question 15

Refer to the exhibit. An analyst runs the search and expects the `country`, `region`, and `city` fields to appear in the results, but they do not. What is the most likely reason?

Accepted Answer

The lookup file is not defined as a lookup in Splunk's lookups definitions.. Splunk requires a lookup file to be explicitly defined in Settings > Lookups > Lookup definitions before it can be used in a search. Without this definition, the `lookup` command will not find the file, and no fields will be added to the results, even if the file exists on disk.

Answer

The fields in the lookup must have different names than the output fields.

Answer

The clientip field in the events has a different data type than the lookup.

Answer

The lookup command should use OUTPUTNEW instead of OUTPUT.
