Practice scenarios

Question 1mediummultiple choice

Full question →

A Splunk administrator is troubleshooting a slow search that uses the transaction command. The search correlates events by 'user_uuid' with a maxspan of 1 hour. The administrator suspects that many orphan events (events that never complete a transaction) are causing performance issues. Which approach can help identify and possibly exclude orphan events from the transaction?

A
Increase maxspan to allow more events to complete.
Why wrong: Increasing maxspan may include more events but does not specifically address orphans and could worsen performance.
B
Use the 'mvlist' option to list all user_uuid values.
Why wrong: mvlist is not a valid transaction option.
C
Use the 'keepevicted=true' option and then filter out evicted events in a subsequent search.
keepevicted=true preserves events that were not included in any transaction, allowing you to analyze or exclude them.
D
Add 'closed_txn=1' to the transaction command to only output complete transactions.
Why wrong: closed_txn is not a valid transaction option.

Question 2mediummulti select

Full question →

A Splunk administrator is troubleshooting a search that uses the `transaction` command. The search is taking too long to complete and returning incomplete results. Which TWO changes are most likely to improve performance and accuracy of transaction searches? (Choose TWO.)

A
Remove the `maxspan` parameter to allow transactions of any duration.
Why wrong: Removing maxspan can cause very long transactions, increasing memory and time.
B
Use `mvcombine` to combine multivalued fields before the transaction.
Why wrong: mvcombine is not relevant to transaction performance.
C
Use `fields` before `transaction` to include only necessary fields.
Reduces data volume processed by transaction.
D
Increase the `maxevents` value to allow more events per transaction.
Why wrong: Increases memory usage and may worsen performance.
E
Set an appropriate `maxspan` value based on the expected duration of correlated events.
Limits the time window for grouping, improving performance and preventing runaway transactions.

Question 3hardmultiple choice

A search `index=main | eval weekday=strftime(_time,"%A") | stats count by weekday | sort - count` shows that Monday has the highest count. However, the user suspects that Monday data is double-counted due to timezone offset. What should be done to investigate?

A
Use `date_wday` field which is based on the local time by default if configured.
`date_wday` is automatically generated by Splunk based on the configured timezone in the source type.
B
Use `strftime(_time,"%w")` instead of %A to avoid string comparison issues.
Why wrong: Using numeric weekday does not address timezone concerns.
C
Apply `| convert timeformat="%A" tz=US/Mountain _time as weekday` to adjust timezone.
Why wrong: `convert` does not accept timezone parameter in that way.
D
Use `eval weekday=strftime(_time + timezone_offset, "%A")` with a fixed offset.
Why wrong: Hardcoding offset is not robust; the timezone may vary.

Question 4mediummultiple choice

Full question →

A Splunk administrator is troubleshooting a slow dashboard that uses a timechart with a large dataset. Which of the following is a best practice to improve performance?

A
Increase the number of concurrent searches
Why wrong: Concurrent searches do not improve the speed of a single search.
B
Use the eval command to add fields
Why wrong: Adding eval commands increases processing time.
C
Use data model acceleration
Data model acceleration speeds up searches on data models significantly.
D
Increase the search bucket count
Why wrong: More buckets can increase overhead; not a best practice for performance.

Refer to the exhibit. An administrator is configuring a CIDR match lookup for geo-IP. The lookup is not working. What is most likely the issue?

Exhibit

[transform:geo_ip]
filename = GeoLiteCity.dat
max_matches = 1
[match_type = cidr

A
The max_matches setting should be 0
Why wrong: max_matches=1 is valid; 0 would allow multiple matches.
B
The filename should include the full path
Why wrong: The filename is correct as just the file name; Splunk looks in the lookups directory.
C
The stanza name should be 'geo_ip' without brackets
Why wrong: The brackets are correct for the stanza header.
D
The match_type should be 'match_type = cidr' without brackets
It should be a setting, not a stanza header.

An admin is troubleshooting a saved search that uses the `| `my_macro` command. The macro definition is `stats count by $1$`. The saved search is scheduled to run hourly. Which of the following issues could cause the saved search to fail? (Choose three.)

A
The macro argument passed in the saved search contains a space without quotes
Correct: Spaces in arguments require quoting.
B
The macro definition includes a pipe at the start but the invocation also includes a pipe
Correct: Double pipe results in syntax error.
C
The saved search's time range is set to 'All time'
Why wrong: Incorrect: 'All time' may not cause failure, though it can be resource-intensive.
D
The macro is not shared to the app where the saved search is stored
Correct: Macro must be accessible to the saved search's app.
E
The saved search has a cron schedule that overlaps with another saved search
Why wrong: Incorrect: Overlap may cause skip but not failure.

Question 7mediummultiple choice

Full question →

An admin notices that a saved search with a scheduled alert is not triggering as expected even though the search returns results. The search uses a macro with arguments. Which troubleshooting step should the admin take first?

A
Ensure that the macro name does not conflict with existing commands or other macros.
Why wrong: Conflict is possible but less likely than syntax error.
B
Review the macro definition for syntax errors, such as missing brackets or incorrect argument references.
Macro syntax errors are a common cause of search failure.
C
Verify the macro's permissions are set to global.
Why wrong: Permissions are important but not the first step if it was recently defined.
D
Check the search head's job inspector for the expanded search string.
Why wrong: Job inspector shows the executed search; it's a good step but not first.

Question 8hardmultiple choice

Full question →

A user defined a macro that includes a lookup command. The macro works correctly in ad-hoc searches. However, when the macro is used in a scheduled saved search, the macro fails to expand. Administration confirms the macro is shared globally. What is the most likely cause of this failure?

A
The macro expects arguments that are not provided in the saved search.
Why wrong: If the macro works ad-hoc, arguments are likely provided correctly.
B
The lookup used in the macro is not accessible in the saved search's app context.
All knowledge objects used in the macro must be accessible from the saved search's app context.
C
The macro is not shared to the global context despite confirmation.
Why wrong: The question states it is shared globally.
D
The macro contains a syntax error that only appears at schedule time.
Why wrong: If the macro works ad-hoc, there is no syntax error.

Question 9hardmultiple choice

Full question →

A security team uses the CIM 'Authentication' data model to investigate failed logins. They have enabled acceleration on the data model and set a summary range of '1d'. After one week, searches against the data model are still slow and use the `search` command instead of `tstats`. What should they check first?

A
Confirm that the data model acceleration is built and that the search time range is within the summary range.
If the search time range exceeds the summary range, `tstats` cannot be used and Splunk falls back to search.
B
Verify that the 'Authentication' data model is assigned to the correct index.
Why wrong: Data models are not assigned to indices; they rely on tags and field extractions.
C
Ensure that the 'Authentication' data model has the 'authentication' tag on relevant events.
Why wrong: While tags are required, if acceleration is already enabled and events are in the model, this is not the first check.
D
Check that the data model acceleration has completed building for the exact time range of the search.
Why wrong: Acceleration builds increments; as long as the range is within the summary range, exact match not required.

Question 10easymultiple choice

Full question →

A user reports that a macro named `my_macro` is not working in a search. The macro is defined with no arguments and uses a simple search string. What is the most likely issue?

A
The macro permissions are not shared to the user's role.
Correct: Macros require proper permissions to be usable by others.
B
The macro is defined with wrong arguments.
Why wrong: Since the macro has no arguments, this is not relevant.
C
The macro name is misspelled in the search.
Why wrong: Misspelling would cause an error message, not a silent failure.
D
The macro contains a subsearch that fails.
Why wrong: A subsearch failure would produce an error, not just no results.

A Splunk admin is troubleshooting a transaction that groups firewall allow and deny events by session ID. The transaction should end when a deny event occurs for that session. Which transaction option should be used to define the end condition?

A
endswith="action=allow"
Why wrong: Incorrect: This would end on allow, which is opposite of the requirement.
B
startswith="action=deny"
Why wrong: Incorrect: This defines the start condition, not the end.
C
endswith="action=deny"
Correct: This ends the transaction when a deny event is encountered.
D
maxevents=2
Why wrong: Incorrect: This limits the number of events per transaction, not the end condition.

Question 12hardmultiple choice

Full question →

A Splunk administrator is troubleshooting a search that uses the transaction command to group login and logout events. The search runs but returns no results even though both types of events exist. The events are separated by at most 5 minutes. The current transaction command is:

`index=auth (action=login OR action=logout) | transaction action maxspan=10m maxpause=2s`

What is the most likely cause?

A
The maxspan value is too large, causing events to be grouped incorrectly.
Why wrong: maxspan is the maximum total duration; 10 minutes is reasonable.
B
The transaction command requires the connected=true argument to group events.
Why wrong: connected=true is the default; changing it would affect ordering but not grouping.
C
The transaction command requires keepevents=true to retain all events.
Why wrong: keepevents only affects whether raw events are appended; missing events is not the issue.
D
The maxpause value is too small; events may be more than 2 seconds apart.
maxpause sets the maximum time between events in a transaction; 2 seconds may be too restrictive.

Question 13easymultiple choice

Full question →

The security operations center (SOC) team at a medium-sized enterprise uses Splunk to investigate potential threats. They maintain a CSV lookup file named 'threat_intel.csv' that contains a list of known malicious IP addresses along with a threat score. The lookup is configured in transforms.conf as:

[threat_intel]

filename = threat_intel.csv match_type = WILDCARD(ip)

They frequently run the following search to enrich firewall events with threat scores:

index=firewall sourcetype=firewall_logs | lookup threat_intel src_ip OUTPUT threat_score | where threat_score > 5

Recently, analysts noticed that some IP addresses known to be present in the lookup file are not being matched in search results. They have verified that the lookup file is correctly formatted and contains those IPs, and the transforms.conf has not been altered. They also confirmed that the events contain the field src_ip with the correct IP addresses. Which of the following is the most likely cause of the missing matches?

A
The IP addresses in the lookup file are stored in a different case (e.g., uppercase) than in the events (lowercase).
Lookups are case-sensitive by default; mismatched case prevents matching. This is a common issue.
B
The search is limited to a time range that excludes events with those IP addresses.
Why wrong: The analysts confirmed the events exist, so time range is not the issue.
C
The lookup file contains duplicate entries for some IPs, causing conflicts.
Why wrong: Duplicate entries would not cause missing matches; they might cause multiple matches but not prevent matching.
D
The lookup command requires the input_fields parameter to specify which field to use for matching.
Why wrong: The lookup command automatically uses the field name from the event if no input_fields is specified; it is not required.

Question 14mediummultiple choice

Full question →

A large e-commerce company uses Splunk to monitor its web application performance. The application logs every HTTP request with fields: `transaction_id`, `url`, `response_time_ms`, `status`. Currently, the team uses the following search to identify slow page loads:

`index=web sourcetype=access_combined | transaction transaction_id maxspan=60s | eval total_time = sum(response_time_ms) | where total_time > 5000`

However, the search returns no results even though there are known slow pages. The team verified that logs contain `transaction_id` values and that some pages take over 10 seconds. What is the most likely reason the search fails to identify slow pages?

A
The `maxspan=60s` is too short; some page loads may take longer than 60 seconds, causing incomplete transactions.
Why wrong: Even if some take longer, known 10-second loads should be captured.
B
The `transaction` command is grouping by `transaction_id`, but the events might have different transaction_id values for the same page load.
Why wrong: If transaction_id is correctly logged, this should work.
C
The field name is misspelled; it should be `response_time` not `response_time_ms`.
Why wrong: No evidence of misspelling.
D
The `eval total_time = sum(response_time_ms)` is incorrect because after `transaction`, `response_time_ms` is a multivalue field, and `sum()` does not automatically calculate the sum of multivalue fields.
`sum()` is a statistical function; you need `eval total_time = mvsum(response_time_ms)` or use `stats sum` in a different approach.
