You are building a dashboard for the security team. The base search returns events from the `authentication` sourcetype. You need to enrich each event with the user's department and manager, which are stored in a CSV lookup named `user_info.csv`. The lookup has not been defined in Splunk yet. You want the enrichment to happen at search time without modifying the raw events. Which search command should you use?
You manage a Splunk deployment where a scheduled alert named "Failed_Logins" is configured to run every 15 minutes. The alert searches for failed login events and appends a lookup field `user_risk` from a CSV lookup named `user_risk_lookup`. The alert has been triggering as expected, but the `user_risk` field is missing from the results. You have verified that the lookup file exists and contains the correct data. You run the search manually and see that the `user_risk` field is populated. What is the most likely reason the field is missing in the alert results?
A security analyst maintains a CSV lookup file named threat_actors.csv that maps attacker IP addresses to campaign names. The lookup definition uses the default match type and is case-sensitive. A new batch of events contains IP addresses stored in a transformed field called src_ip. The analyst runs a search that includes the lookup command and notices that some events are not enriched. Which lookup command syntax will correctly enrich the events with campaign names from the lookup while preserving all existing fields?
You are creating a lookup definition that uses a KV Store collection. The lookup will be used in a search to enrich events with user details. You want to ensure that the lookup returns only the first matching entry when multiple entries match the lookup key. Which setting should you configure in the lookup definition?
You are using the `lookup` command in a search to enrich events with data from a CSV lookup definition named `user_info`. After running the search, you notice that events with a `user` field containing uppercase letters (e.g., `JSMITH`) are not being enriched, while events with lowercase `user` values (e.g., `jsmith`) are enriched correctly. The lookup definition has `case_sensitive_match` set to its default value. What is the most likely cause of this behavior?
You are using the lookup command to enrich events with a CSV lookup that contains a field named priority. Your events already have a field named priority with different values. You want the lookup to add a new field called severity based on the lookup's priority, but you do not want to overwrite the existing priority field. Which syntax should you use?
You need to create an alert that runs a search every hour and, when the results contain more than 100 events, sends an email to the security team and adds a note to a KV Store collection for further analysis. The alert should not trigger more than once per hour even if the condition remains true. Which alert configuration should you use?
You are configuring a new alert in Splunk Enterprise. The alert must trigger an action that sends a formatted message to a third-party incident management system via a webhook. You need to define the alert action. Which two steps are required to set up this custom webhook alert action? (Choose two.)
You are optimizing a search that uses a large CSV lookup. The lookup is applied to millions of events, and you need to improve performance. Which two actions can you take to reduce lookup overhead? (Choose two.)
You are designing a lookup strategy for a large environment with millions of events per day. You need to optimize lookup performance and reduce search time. Which two actions should you take? (Choose two.)
You are using the `lookup` command in a search to enrich events with data from a CSV lookup. You want to replace the value of an existing field in your events with a value from the lookup, but only if the lookup returns a match. Which argument should you use in the `lookup` command?
You are troubleshooting a scheduled alert that is not triggering. You have verified that the search returns results when run manually, the alert is enabled, and the schedule is correct. You also confirmed that the alert's permissions are set correctly. Which additional configuration should you check that could prevent the alert from triggering?
You are creating a lookup definition that points to a CSV file. The CSV contains a 'user' column with values like 'JSMITH' and a search result has 'jsmith'. You need the lookup to match regardless of case. Which configuration setting should you change?
You have an automatic lookup that enriches events with user details from a CSV file. The lookup is configured to output a field called 'department'. However, you notice that some events already have a 'department' field with a value, and you want to preserve the original value. Which setting in the automatic lookup configuration should you use?
You have an alert that runs a scheduled search every hour. The search uses a lookup to filter events, but the lookup file is updated daily at 2 AM. You notice that the alert sometimes triggers with stale lookup data. Which configuration should you adjust to ensure the alert uses the most current lookup data?
A threat intelligence team maintains a KV Store collection named `malware_hashes` containing a `hash` field. Analysts want to enrich events in a search by adding a `malware_family` field, but the input field in the events is named `file_hash` and must be matched against the `hash` field in the collection. The lookup definition `malware_lookup` already exists and points to this collection. Which search syntax correctly enriches the events?
A security team wants an alert that enriches blocked-connection events with a department name from a CSV lookup, but the lookup file is replaced nightly by an automated job. The lookup occasionally becomes unreadable mid-replacement, causing the alert to return no enriched results. Which approach most reliably keeps the alert working while the file is replaced?
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?
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?
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?
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?
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?
You are configuring a lookup definition named `product_owner` that uses a CSV file. The lookup contains a field `product_id` that in your event data is sometimes lowercase and sometimes uppercase. You need the lookup to match regardless of case. Which advanced setting in the lookup definition should you configure?
You have an automatic lookup that enriches events with `user_department` from a CSV file. You run a search and notice that the `user_department` field is not appearing in the results, even though the lookup file contains the correct mappings and the automatic lookup is enabled. Which of the following is the most likely cause?
You need to create a lookup that will be updated frequently with new data from a search. Which lookup type should you use to allow for fast, concurrent writes and reads?
You have an alert that runs a search every 15 minutes and triggers when the number of failed login attempts exceeds 10. The alert is configured to send an email. After a week, you notice that the alert triggered multiple times but no emails were received. You verify the search returns results and the email settings are correct. What is the most likely cause?
You maintain a KV Store lookup named asset_inventory in the search app. A scheduled search populates it every 15 minutes. A dashboard user reports that when they run a search that joins against asset_inventory, some events return no lookup fields, even though the assets exist in the collection. You confirm the lookup definition is shared globally and the collection contains the expected keys. Which action should you take to ensure the lookup is usable by the dashboard user's searches without granting them write access to the collection?
You are building a dashboard panel that must display the top 10 source IP addresses by count of failed logins, and the results must be returned as a single results set with a field named 'fail_count'. You also need to add a drilldown that passes the selected source IP to another dashboard. Which search command sequence correctly produces the required results set while keeping the field name 'fail_count'?
A Splunk administrator is designing a lookup that will be used in a real-time alert to enrich incoming events with user department information. The lookup must support rapid updates without restarting Splunk, allow multiple users to modify entries concurrently, and provide the ability to define a lookup with a case-sensitive match. The administrator wants to use a KV Store lookup instead of a CSV lookup. Which two statements accurately describe KV Store lookups in this context? (Choose two.)
An analyst uses the following search to enrich events: index=web | lookup local=1 web_assets clientip OUTPUTNEW asset_owner, asset_criticality. They notice that events where clientip matches multiple entries in web_assets get an arbitrary owner value. They need deterministic behavior where the first matching entry in the lookup is used. Which approach should they take?
You have a CSV lookup file 'employees.csv' with fields employee_id, department, and manager. You need to enrich incoming events that contain 'user' by matching user to employee_id and adding department and manager to the events. The lookup should apply automatically to all searches against the 'main' index without requiring users to add a lookup command. What should you configure?
A Splunk power user is configuring an alert that must trigger only when a search returns more than 100 events in a 5-minute window. The user wants to avoid duplicate alerts for the same set of events and wants the alert to include a link to the search results in the notification email. Which alert configuration should the user set to prevent duplicate alerts?
A security team wants to trigger an alert when a user account is locked out more than five times in 10 minutes. They create a saved search with the following SPL: index=security EventCode=4740 | stats count by user | where count > 5. They configure the alert to run every 10 minutes and trigger when the number of results is greater than 0. Which alert action should they configure to automatically create a ticket in their incident management system?
You have a lookup definition 'user_info' that maps user to department. In a search, you run: index=main | lookup user_info user OUTPUTNEW department AS dept. Some events already contain a field named 'dept'. What is the result for those events?
You have a lookup definition named `employee_lookup` that maps `employee_id` to `department` and `manager`. You want to use this lookup in a search to add the `department` and `manager` fields to your events, but you also want to ensure that if the `department` field already exists in the event, it is not overwritten. Which `lookup` command syntax achieves this?
You are configuring a new alert in Splunk Enterprise Security. You want to ensure that the alert triggers only when a specific condition is met and that it performs multiple actions. Which two alert settings are required to define the alert's trigger condition and actions? (Choose two.)
You need to create a lookup definition that references a CSV file stored in the `lookups` directory of your app. Which configuration file is used to define the lookup?
You have a scheduled alert that runs every hour and triggers when the number of results is greater than 0. The alert is configured to send an email. You notice that the alert triggers and sends an email every hour, even when there are no new events. The search itself returns results because it includes a `stats` command that always returns at least one row (e.g., a count of 0). How can you modify the alert to only trigger when there are actual events?

You are using the lookup command to enrich your search results with a CSV lookup. You want to add a field from the lookup only if that field does not already exist in your events. Which argument should you use?
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.)
A compliance officer needs an alert that runs a saved search every day at 06:00 and emails a report of all privileged account creations found in the previous 24 hours, regardless of how many events are returned. Which trigger configuration accomplishes this?
A Splunk administrator uploads a new CSV lookup file containing a column of IPv4 addresses in CIDR notation. Analysts need searches to match individual event IPs against these ranges rather than requiring exact string equality. Which lookup definition setting must be configured?
