SPLK-1003 Practice Test 32 — 15 Questions

Question 1

Refer to the exhibit. What does the pct field represent?

Accepted Answer

The percentage of each status within each one-hour time bucket.. The `pct` field in the context of a time-based chart (e.g., `timechart count by status`) represents the percentage of each status value within each one-hour time bucket. This is calculated by dividing the count of a specific status in that bucket by the total count of all statuses in the same bucket, then multiplying by 100. Option C correctly identifies this per-bucket proportional breakdown.

Answer

The running total percentage of events over time.

Answer

The percentage of each status across the entire time range.

Answer

The percentage of events for that status compared to the maximum count in that hour.

Question 2

Which command extracts a field named 'ip' from the raw event using a regex pattern?

Accepted Answer

rex "ip=(?\d+\.\d+\.\d+\.\d+)". Option B is correct because the `rex` command uses the named capture group syntax `(?...)` to extract a field named 'ip' from the raw event. The pattern `(?\d+\.\d+\.\d+\.\d+)` matches an IPv4 address and assigns it to the field 'ip'. By default, `rex` operates on the `_raw` field, so no explicit `field=_raw` is needed, and the syntax `(?...)` is the correct Splunk named capture group syntax.

Answer

rex "ip=(?\d+\.\d+\.\d+\.\d+)"

Answer

rex field=_raw "ip=(?P<ip>\d+\.\d+\.\d+\.\d+)"

Answer

rex field=_raw "ip=(?<ip>\d+\.\d+\.\d+\.\d+)"

Question 3

Refer to the exhibit. The search returns 50 results after the `where` command. What is the purpose of the `eval` command?

Accepted Answer

To create a new field 'severity' based on a condition.. The `eval` command in Splunk is used to create new fields or evaluate expressions. In this context, the `eval` command creates a new field called 'severity' by evaluating a conditional expression that assigns a value based on the 'count' field. This is confirmed by the search returning 50 results after the `where` command, meaning the `eval` command does not filter results but instead adds a computed field.

Answer

To filter out results with count ≤ 100.

Answer

To modify the 'count' field.

Answer

To rename the 'count' field to 'severity'.

Question 4

A user wants to create a report that shows the top 5 sources of errors, excluding a specific source 'host1'. Which SPL is correct?

Accepted Answer

index=main sourcetype=access_combined status>400 NOT host="host1" | top limit=5 source. Option A is correct because it filters out 'host1' before the `top` command runs, ensuring that the top 5 sources of errors are calculated from the remaining data. The `NOT host="host1"` clause is placed in the base search, which is the most efficient approach and guarantees that 'host1' is excluded from the statistical aggregation.

Answer

index=main sourcetype=access_combined status>400 | top limit=5 source | where source!="host1"

Answer

index=main sourcetype=access_combined status>400 | top limit=5 source | search source!="host1"

Answer

index=main sourcetype=access_combined status>400 | search NOT host=host1 | top limit=5 source

Question 5

Refer to the exhibit. The lookup 'lookup_user_info' is used in a search: `| lookup lookup_user_info user_id OUTPUT department`. Users report that many events show 'UNKNOWN' as department even though the user_id exists in the CSV. What is the most likely cause?

Accepted Answer

The field name in the CSV header is 'User_ID' (capital U), while the event field is 'user_id' (lowercase). Splunk field matching is case-sensitive.. Option B is correct because Splunk lookups are case-sensitive when matching field values. The exhibit shows the CSV header uses 'User_ID' (capital U), while the search references 'user_id' (lowercase). Since the lookup field name in the definition must exactly match the event field name, the mismatch causes the lookup to fail, returning 'UNKNOWN' for all events even when the user_id exists in the CSV.

Answer

The lookup file is not distributed to all indexers.

Answer

The match_type is not specified, defaulting to EXACT, but the CSV contains case variations.

Answer

The max_matches should be set to 0.

Answer

The lookup definition is missing the default_match setting, which should be set to 'no_match'.

Question 6

A search returns duplicate events for the same user. The analyst wants to keep only the first occurrence of each user based on timestamp. Which sequence of commands is best?

Accepted Answer

sort _time | dedup user. Option D is correct because it first sorts events by timestamp in ascending order (oldest first), then applies `dedup user` to keep only the first occurrence of each user. Since `dedup` retains the first event it encounters for each field value, sorting by `_time` ensures that the earliest event for each user is kept, satisfying the requirement to keep only the first occurrence based on timestamp.

Answer

sort -_time | dedup user

Answer

dedup user

Answer

dedup user | sort _time

Question 7

Refer to the exhibit. What does the final result represent?

Accepted Answer

Hours where any user's logon count is more than double the average for that hour.. The `eventstats` command calculates a per-hour average logon count across all users. The `where` clause then filters for events where a specific user's logon count for that hour is more than double that hourly average. This directly matches option C: hours where any user's logon count exceeds twice the average for that hour.

Answer

Users who log on more than twice on average.

Answer

Hours where the total logon count is more than double the average.

Answer

Users who have a logon count greater than twice their personal average.

Question 8

Which TWO of the following are limitations of the transaction command in Splunk?

Accepted Answer

It defaults to a maximum of 1000 events per transaction.. Option C is correct because the transaction command defaults to a maximum of 1000 events per transaction. If a transaction exceeds this limit, Splunk will close the transaction and start a new one, which can lead to incomplete or unexpected results. This limit can be increased using the maxevents argument, but it is a key constraint to be aware of when correlating large sequences of events.

Answer

It cannot be used inside an eval statement.

Answer

It only works with indexed fields.

Answer

It cannot correlate events from multiple sourcetypes.

Question 9

Which TWO of the following are valid ways to define arguments in a Splunk macro?

Accepted Answer

In the macro definition, use $arg1$, $arg2$ as placeholders for the arguments.. Option A is correct because Splunk macros use named placeholders like $arg1$, $arg2$ in the macro definition to represent arguments. When the macro is invoked, these placeholders are replaced with the actual values passed by the user, allowing flexible and reusable search snippets.

Answer

In the macro definition, use $1$, $2$ as positional placeholders.

Answer

Arguments are automatically inferred from the search string in the macro definition.

Answer

In the macro definition, use named placeholders like $error_code$.

Question 10

Refer to the exhibit. A security analyst notices that some transactions have a duration greater than 600 seconds even though maxpause is set to 5 minutes (300 seconds). What is the most likely reason?

Accepted Answer

The maxspan setting of 30 minutes allows the total transaction duration to reach up to 1800 seconds.. Option D is correct because the `maxspan` parameter in the transaction command sets an upper limit on the total duration of the transaction from the first to the last event, regardless of the `maxpause` setting. With `maxspan=30m` (1800 seconds), a transaction can have a total duration up to 1800 seconds, even if individual gaps between events exceed `maxpause=5m` (300 seconds). The `maxpause` only limits the idle time between consecutive events, not the overall span, so transactions with gaps larger than 300 seconds but within the 1800-second span are still valid.

Answer

The transaction command is including events that are more than 5 minutes apart because the maxpause is ignored when maxspan is set.

Answer

The eventcount field is inflated, causing duration to be calculated incorrectly.

Answer

The duration field represents milliseconds, so 600 seconds is actually 0.6 seconds.

Question 11

Which SPL command can be used to create a new field based on a conditional evaluation, such as setting a status field to 'critical' if a numeric threshold is exceeded?

Accepted Answer

| eval status=if(value>100,"critical","normal"). The `eval` command in SPL is used to create new fields or modify existing ones by evaluating expressions. The `if()` function within `eval` allows conditional logic, making `| eval status=if(value>100,"critical","normal")` the correct syntax to create a new field 'status' that is set to 'critical' when the numeric field 'value' exceeds 100, and 'normal' otherwise.

Answer

| makemv

Answer

| rex field=_raw

Answer

| convert status=if(value>100,"critical","normal")

Question 12

Which command returns the list of all sourcetypes in a specific index?

Accepted Answer

| metadata type=sourcetypes index=main. Option D is correct because the `| metadata` command with `type=sourcetypes` retrieves a list of all sourcetypes present in a specified index, along with their earliest and latest timestamps. This command queries the index metadata directly, making it the appropriate tool for listing sourcetypes within a given index.

Answer

| sourcetype count index=main

Answer

| eventtype count index=main

Answer

| metasearch index=main sourcetype=*

Question 13

A user wants to add a field showing the average value of a numeric field `latency` for each host, without reducing the number of events. Which command should be used?

Accepted Answer

eventstats. The `eventstats` command is correct because it calculates aggregate statistics (like average) over a field and appends the result as a new field to every event, preserving the original event count. Unlike `stats`, which reduces the dataset to one row per group, `eventstats` enriches each event with the computed value without removing any events.

Answer

eval

Answer

stats

Answer

streamstats

Question 14

Refer to the exhibit. What is the purpose of this search?

Accepted Answer

To enrich the server list with current status from the main index.. The search uses `inputlookup` to load a lookup file (server_list), then pipes it into `eval` to create a `status` field set to 'missing'. The `append` command adds all events from the main index (source=main sourcetype=access_combined) that match the server names in the lookup. The `stats values(*) as * by server` merges the two datasets per server, so if a server from the lookup has matching events in the main index, its `status` field will be overwritten with the actual status from the main index (e.g., '200'). Servers with no matching events retain 'missing'. This enriches the lookup data with current status from the main index.

Answer

To compare two datasets and show only matching server names.

Answer

To update the lookup file with current status.

Answer

To find servers that are missing from the lookup.

Question 15

Which of the following searches correctly computes the average response time per host?

Accepted Answer

index=main | stats mean(response_time) by host. Option A is correct because the `stats` command with `mean(response_time)` calculates the arithmetic mean of the response_time field, and the `by host` clause groups the calculation per host, producing the average response time for each host. This is the standard Splunk syntax for computing averages in a grouped statistics table.

Answer

index=main | stats average(response_time) by host

Answer

index=main | eventstats avg(response_time) by host

Answer

index=main | stats avg response_time by host
