SPLK-1004 Lookups And Alerts Practice Test 3 — 15 Questions

Question 1

Where is the most appropriate place to check for errors related to a failed lookup execution?

Accepted Answer

The _internal index. The _internal index stores Splunk's own operational logs, including search-time errors, lookup execution failures, and messages from the search process. Checking _internal is the standard way to diagnose why a lookup failed, as it contains detailed error messages from the search and knowledge object subsystems.

Answer

The Splunk Web UI dashboard

Answer

The lookup csv file

Answer

The savedsearches.conf file

Question 2

You need to update a lookup table periodically using the output of a scheduled search. Which command is required to write the search results to the lookup file?

Accepted Answer

outputlookup. The outputlookup command is used to write search results to a lookup file. It takes the results of a search and outputs them to a specified lookup table, either overwriting or appending.

Answer

lookup_update

Answer

inputlookup

Answer

lookup

Question 3

You have configured an automatic lookup that is failing to populate. You verified the lookup definition and the automatic lookup rule. What is the most likely reason for the failure?

Accepted Answer

Field name mismatch between event and lookup.. An automatic lookup joins fields from the lookup table to fields in the event stream at search time. If the field name referenced in the lookup definition (the 'Lookup input field') does not exist in the events, or the case/name differs from what the lookup CSV header expects, the lookup silently returns no matches and the lookup fields remain null. Since the definition and automatic rule were already verified, the most common remaining cause is a field name mismatch between the event data and the lookup table.

Answer

The lookup is set to read-only.

Answer

The lookup is shared globally.

Answer

The lookup table file is too large.

Question 4

You need to ensure that an alert notifies a specific team via email only when the number of errors exceeds 50 in 5 minutes. What is the correct way to implement this?

Accepted Answer

Set trigger condition to 'greater than' 50 results in 5 minutes.. The trigger condition in a Splunk saved search defines the threshold that must be met for the alert to fire. Setting it to 'greater than' 50 results over a 5-minute window directly implements the requirement of notifying only when errors exceed 50. The alert action (email) is configured separately, and the trigger condition is what governs when that action executes.

Answer

Enable 'Real-time' alert mode.

Answer

Use a cron expression of */5.

Answer

Configure the 'Action' to 'Email'.

Question 5

A user wants to restrict an alert to trigger only once per hour, even if the search returns results every minute. Which setting should be modified?

Accepted Answer

Throttling. Alert throttling in Splunk suppresses alert actions for a specified period after a trigger, so setting throttling to one hour ensures the alert fires at most once per hour even if the search runs every minute. Throttling can be configured per alert and can suppress based on fields or the entire alert.

Answer

Cron schedule

Answer

Alert frequency

Answer

Trigger conditions

Question 6

Which action can be triggered by a Splunk alert?

Accepted Answer

Send an email. Splunk alerts can trigger a variety of actions, including sending an email, running a script, using a webhook, or logging the event. Sending an email is a standard alert action, making C correct.

Answer

Restart the indexer

Answer

Modify user passwords

Answer

Delete search history

Question 7

You are using an automatic lookup. If you want to overwrite an existing field in your search results with a value from the lookup, which setting should be enabled?

Accepted Answer

Overwrite field values. The 'Overwrite field values' setting in an automatic lookup configuration allows values from the lookup to replace existing field values in the search results. This is necessary when you want the lookup to take precedence over fields already present in the events. Without this setting, the lookup will not overwrite existing fields.

Answer

Default values

Answer

Force match

Answer

Strict match

Question 8

What is the result of using 'OUTPUTNEW' instead of 'OUTPUT' in a lookup command?

Accepted Answer

It only adds fields if they do not already exist.. In a lookup command, OUTPUTNEW only adds fields from the lookup if those fields do not already exist in the event. If the field already exists, the lookup value is ignored. This contrasts with OUTPUT, which overwrites existing fields. Thus, option C is correct.

Answer

It forces an error if the lookup is empty.

Answer

It performs a case-insensitive lookup.

Answer

It creates a new lookup table.

Question 9

What is the primary purpose of a lookup?

Accepted Answer

To add external data to events.. A lookup in Splunk is a mechanism that enriches events by adding fields from an external data source (like a CSV file or a KV Store collection) based on a common field. This allows you to correlate indexed event data with additional context, such as user details, asset information, or threat intelligence, without re-indexing the raw data. The primary purpose is to add external data to events, making option B correct.

Answer

To store user dashboards.

Answer

To index raw data.

Answer

To filter out unwanted data.

Question 10

When configuring a CSV lookup file, where is the file uploaded in Splunk?

Accepted Answer

Settings > Lookups > Lookup table files. CSV lookup files in Splunk are managed as lookup table files, which are uploaded and stored via Settings > Lookups > Lookup table files. This is the dedicated location where Splunk stores the actual CSV content that lookup definitions reference. Once uploaded here, a lookup definition is created to bind the file to a name usable in SPL via the lookup command.

Answer

Settings > Indexes

Answer

Settings > Field extractions

Answer

Settings > Data inputs

Question 11

Which of the following is a key advantage of using KV Store lookups over CSV lookups?

Accepted Answer

They support dynamic updates and data types.. KV Store lookups support dynamic updates and preserve data types, unlike CSV lookups which are static files. This makes KV Store ideal for lookups that change frequently or require field-type fidelity. CSV lookups are read-only at search time and treat all values as strings.

Answer

They don't require lookup definitions.

Answer

They use less disk space.

Answer

They are faster for static data.

Question 12

Which search command is used to display the contents of a lookup table?

Accepted Answer

inputlookup. The 'inputlookup' command is specifically designed to read and display the contents of a lookup table file (CSV or KV Store) as search results. It is the standard command for viewing lookup data without joining it to an event stream. Running '| inputlookup mylookup.csv' returns all rows and columns from the lookup.

Answer

table

Answer

lookup

Answer

outputlookup

Question 13

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 14

You need to ensure that an alert does not fire multiple times for the same user if they trigger the alert 50 times in one minute. Which throttling setting should you use?

Accepted Answer

Suppress results by field. To prevent an alert from firing multiple times for the same user, you need to suppress results based on a field (e.g., user). The 'Suppress results by field' throttling setting groups results by a specified field and only triggers once per unique field value within the throttle window. This ensures one alert per user even if they trigger 50 times in a minute.

Answer

Suppress all results

Answer

Throttling by time only

Answer

Result limit

Question 15

What is the result of setting an alert's priority to 'High'?

Accepted Answer

It elevates the alert in the Triggered Alerts list.. In Splunk, an alert's priority setting (High, Medium, Low) does not change execution speed, resource usage, or notification behavior. It only affects the sort order in the Triggered Alerts list, elevating High-priority alerts to the top for visibility. This is purely a UI/display attribute.

Answer

It triggers faster.

Answer

It uses more CPU.

Answer

It sends extra emails.
