SPLK-1003 Multiple Select — 10 Questions

Question 1

Which TWO statements correctly describe the behavior of the transaction command in Splunk?

Accepted Answer

It can concatenate the raw text of all events in the transaction into a single event.. Option C is correct because the transaction command can be configured with the `mvraw` option to concatenate the raw text of all events in the transaction into a single event. This is useful when you need to preserve the full log lines of a correlated sequence, such as a multi-step user session or a series of API calls.

Answer

It is not recommended for use with large datasets because it consumes too much memory.

Answer

It merges all fields from all events into a single event, with the last event's field value taking precedence.

Answer

It automatically calculates the duration of each transaction as the difference between the first and last event timestamps.

Question 2

Which TWO of the following are valid reasons to use the Common Information Model (CIM) in a Splunk environment?

Accepted Answer

It improves the ability to correlate events from different technologies.. Option A is correct because the Common Information Model (CIM) provides a standardized set of field names and event tags across different data sources, enabling correlation of events from disparate technologies (e.g., firewalls, IDS, endpoints) using common fields like 'dest_ip', 'src_ip', 'user', and 'action'. This normalization allows Splunk to join or relate events that share the same CIM-compliant fields, making it possible to build coherent security or operational stories across heterogeneous data.

Answer

It improves search performance by pre-aggregating data.

Answer

It provides built-in security monitoring use cases.

Answer

It eliminates the need for custom field extractions.

Question 3

Which TWO of the following are valid uses of the Common Information Model (CIM) in Splunk?

Accepted Answer

Defining tags and event types to categorize data.. Option D is correct because the CIM provides a standardized set of tags and event types that allow you to categorize and classify data from diverse sources, enabling consistent searching and correlation across your Splunk environment. Option E is correct because the CIM defines common field names (e.g., src_ip, dest_ip, user) to normalize data from different technologies, ensuring that searches and dashboards work uniformly regardless of the original data source.

Answer

Defining user roles and permissions for data access.

Answer

Managing license usage across indexers.

Answer

Creating new indexes for faster search performance.

Question 4

Which TWO statements about lookups in Splunk are correct? (Choose two.)

Accepted Answer

The lookup command can be used to add fields from a lookup table to search results. Option A is correct because the `lookup` command in Splunk is specifically designed to enrich search results by adding fields from a lookup table (such as CSV, KV Store, or external lookups) based on matching field values. This is a fundamental use case for lookups in Splunk, allowing you to augment raw event data with additional context from a static or dynamic source.

Answer

External lookups can only be used with CSV files

Answer

CSV lookups can be updated in real-time by adding rows to the CSV file

Answer

Automatic lookups are configured in macros.conf

Question 5

Which TWO are valid methods to join data from a CSV file in a Splunk search?

Accepted Answer

`| lookup myfile.csv`. Option C is correct because the `| lookup` command can reference a CSV file defined as a lookup table in Splunk, allowing field-based enrichment of search results. This is a standard method for joining data from a CSV file within a search, provided the lookup is properly configured in transforms.conf and props.conf.

Answer

`| append myfile.csv`

Answer

`| join myfile.csv`

Answer

`| csvlookup myfile.csv`

Question 6

Which THREE of the following are best practices when using lookups in Splunk?

Accepted Answer

Use the lookup command instead of inputlookup when possible to reduce memory usage. Option A is correct because using the `lookup` command with the `local=t` argument (or when the lookup table is small enough to be loaded into memory) can reduce memory usage compared to `inputlookup`, which always loads the entire lookup file into memory. The `lookup` command can stream results and only loads necessary fields, making it more efficient for large datasets. This is a best practice to avoid out-of-memory errors in distributed search environments.

Answer

Store lookup tables in KV Store when the table has more than 1 million rows

Answer

Always use KV Store lookups for faster performance compared to CSV lookups

Question 7

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.)

Accepted Answer

Use `fields` before `transaction` to include only necessary fields.. Option C is correct because using the `fields` command before `transaction` reduces the amount of data Splunk must process by retaining only the fields necessary for correlation and output. This minimizes memory and CPU overhead, directly improving search performance and reducing the risk of incomplete results due to resource limits.

Answer

Remove the `maxspan` parameter to allow transactions of any duration.

Answer

Use `mvcombine` to combine multivalued fields before the transaction.

Answer

Increase the `maxevents` value to allow more events per transaction.

Question 8

A security analyst needs to correlate authentication events from multiple Windows domain controllers to identify failed logon attempts from a specific user account, and then enrich the results with the user's department and manager from an HR database. Which TWO Splunk features should the analyst use?

Accepted Answer

Data model acceleration. Data model acceleration (B) is correct because it pre-computes and indexes authentication event data from multiple Windows domain controllers, enabling fast, efficient correlation of failed logon attempts for a specific user. Lookup definition (D) is correct because it allows the analyst to define a lookup that enriches the authentication events with the user's department and manager from an external HR database, mapping fields like username to the HR data.

Answer

Time-based lookup

Answer

Subsearch

Answer

Calculated field

Question 9

Which THREE of the following are valid Splunk search commands for determining the number of distinct values of a field?

Accepted Answer

| stats dc(field). Option B is correct because `| stats dc(field)` uses the `dc` (distinct count) function to return the exact number of unique values for the specified field. This is the direct and most efficient command for counting distinct values in Splunk.

Answer

| stats count(field)

Answer

| stats distinct_count(field)

Question 10

Which TWO of the following are valid ways to reference a macro in a search?

Accepted Answer

`macro_name(arg1, arg2)`. Option C is correct because in Splunk, a macro is invoked using backticks with parentheses around its arguments, as in `macro_name(arg1, arg2)`. This syntax tells the search processor to expand the macro definition with the provided arguments before executing the search.

Answer

$macro_name(arg1, arg2)$

Answer

macro_name:arg1, arg2

Answer

| macro_name(arg1, arg2)
