Q: Fields are searchable name and value pairings that differentiates one event from another.

TRUE Explanation: The statement is an accurate definition of a field within the Splunk platform. Fields are fundamental to Splunk's functionality, representing extracted, searchable key-value pairs (also referred to as name-value pairs) from the raw event data. These pairs provide the structured data points that allow users to search, filter, and analyze their data, effectively distinguishing one event from another. For example, in web access logs, the field status=404 clearly differentiates an event from another event with status=200.

Q: Prefix wildcards might cause performance issues.

TRUE Explanation: The statement is correct. Prefix wildcards, also known as leading wildcards (e.g., error), are a significant cause of performance degradation in Splunk searches. The Splunk index and its associated lexicon are optimized for left-to-right, term-based lookups. When a search term begins with a wildcard, Splunk cannot use the lexicon efficiently to identify matching terms. Instead, it must scan every term in the index to check if it ends with the specified string. This exhaustive scan is resource-intensive and can dramatically slow down search performance, especially in large datasets.

Q: In automatic lookup definitions, the _____ fields are those that are not in the event data.

B Explanation: In Splunk, a lookup is used to enrich event data by adding fields from an external source, such as a CSV file. The lookup configuration defines which fields from the lookup source (the output fields) should be added to the events. The process matches one or more fields that already exist in the event data (the input fields) with corresponding fields in the lookup table. Upon a successful match, the values from the specified output fields are appended to the event. Therefore, the output fields are the ones not originally present in the event data.

Question 1

Which command is used to review the contents of a specified static lookup file?

Accepted Answer

C

Explanation: The inputlookup command is a generating command used to read and output the entire contents of a specified lookup file as search results. This allows a user to directly view or "review" the data contained within a static lookup, such as a CSV file, without needing to match it against existing event data. It is the primary method for inspecting the contents of a lookup table directly within the Splunk search interface.

Question 2

What are the three main Splunk components?

Accepted Answer

B

Explanation: A distributed Splunk Enterprise deployment is fundamentally composed of three main components. Forwarders are installed on source machines to collect and send data. Indexers receive, process, and store the data in flat files organized into directories called buckets. Search heads provide the user interface for users to run searches, create reports, and build dashboards; they coordinate search activities across the set of indexers and consolidate the results to present back to the user. This separation of roles allows the Splunk environment to scale effectively for handling large data volumes and user loads.

Question 3

By default, which of the following fields would be listed in the fields sidebar under interesting Fields?

Accepted Answer

B

Explanation: In Splunk Web the Fields sidebar is divided into “Selected Fields” and “Interesting Fields.” The default metadata fields host, source, and sourcetype are always placed in the Selected Fields section. Any other field that occurs in ≥ 20 % of the returned events but is not already in Selected Fields is placed under Interesting Fields. Because index is not one of the default Selected Fields, it meets these criteria and therefore appears in the Interesting Fields list by default.

Question 4

Splunk extracts fields from event data at index time and at search time.

Accepted Answer

TRUE

Explanation: Splunk's data processing architecture performs field extraction at two distinct phases: index time and search time. 1. Index-Time Extraction: As data is ingested, Splunk extracts a small, essential set of default fields. These include host, source, sourcetype, index, and the event timestamp (time). Administrators can also configure persistent index-time field extractions for well-structured data (e.g., JSON, CSV) to improve search performance, though this is less common for unstructured data due to its inflexibility. 2. Search-Time Extraction: This is Splunk's primary and most flexible method for field extraction, often referred to as "schema-on-the-fly." When a search query is executed, Splunk dynamically discovers and extracts fields from the raw event data (raw) based on field extraction configurations and patterns. This allows users to define new fields and change extraction logic without having to re-index the data. Since Splunk utilizes both of these phases for field extraction, the statement is true.

Question 5

You can view the search result in following format (Choose three.):

Accepted Answer

A, B, D

Explanation: After executing a search in the Splunk Search & Reporting application, the results are presented below the events timeline. You can toggle between three primary formats for viewing these results. The Raw format displays the full, unprocessed text of each event. The List format shows the timestamp and presents the fields and values for each event in a structured list. The Table format organizes the events with each event as a row and the selected fields as columns, which is particularly useful for comparing field values across events.

Question 6

This search will return 20 results. SEARCH: error | top host limit = 20

Accepted Answer

FALSE

Explanation: The top command is a transforming command that generates a statistical table of the most frequent values for a specified field. The limit = 20 argument specifies the maximum number of results (rows) to display in that table. The search will only return 20 results if the initial search for "error" finds at least 20 unique values for the host field. If there are fewer than 20 unique host values in the underlying data, the command will return fewer than 20 results. Therefore, the statement that the search will return 20 results is not guaranteed and is false.

Question 7

Which search string matches only events with the status_code of 4:4?

Accepted Answer

D

Explanation: The search string statuscode>403 statuscode 403 AND statuscode < 405. When evaluating numeric fields, the only integer value that satisfies both conditions (being greater than 403 and less than 405) is 404. This method effectively and exclusively filters for the desired events.

Question 8

Fields are searchable name and value pairings that differentiates one event from another.

Accepted Answer

TRUE

Explanation: The statement is an accurate definition of a field within the Splunk platform. Fields are fundamental to Splunk's functionality, representing extracted, searchable key-value pairs (also referred to as name-value pairs) from the raw event data. These pairs provide the structured data points that allow users to search, filter, and analyze their data, effectively distinguishing one event from another. For example, in web access logs, the field status=404 clearly differentiates an event from another event with status=200.

Question 9

Prefix wildcards might cause performance issues.

Accepted Answer

TRUE

Explanation: The statement is correct. Prefix wildcards, also known as leading wildcards (e.g., error), are a significant cause of performance degradation in Splunk searches. The Splunk index and its associated lexicon are optimized for left-to-right, term-based lookups. When a search term begins with a wildcard, Splunk cannot use the lexicon efficiently to identify matching terms. Instead, it must scan every term in the index to check if it ends with the specified string. This exhaustive scan is resource-intensive and can dramatically slow down search performance, especially in large datasets.

Question 10

In automatic lookup definitions, the _____ fields are those that are not in the event data.

Accepted Answer

B

Explanation: In Splunk, a lookup is used to enrich event data by adding fields from an external source, such as a CSV file. The lookup configuration defines which fields from the lookup source (the output fields) should be added to the events. The process matches one or more fields that already exist in the event data (the input fields) with corresponding fields in the lookup table. Upon a successful match, the values from the specified output fields are appended to the event. Therefore, the output fields are the ones not originally present in the event data.

Question 11

Events in Splunk are automatically segregated using data and time.

Accepted Answer

A

Explanation: Splunk is fundamentally architected to handle time-series data. During the indexing process, it automatically performs timestamp extraction for each event, storing this value in the default time field. This timestamp is the primary mechanism Splunk uses to organize, or "segregate," data. Events are stored in index directories called "buckets," which are organized by time range. This automatic, time-based segregation is a core feature that enables efficient searching, data correlation, and the creation of the timeline histogram in the user interface.

Question 12

When an alert action is configured to run a script, Splunk must be able to locate the script. Which is one of the directories Splunk will look in to find the script?

Accepted Answer

A

Explanation: For security and operational integrity, Splunk Enterprise requires that any script triggered by an alert action be located in a specific, recognized directory. The primary system-level directory for these scripts is $SPLUNKHOME/bin/scripts. Placing a script in this location makes it available for selection when configuring the "Run a script" alert action. Splunk also searches for scripts within an app's context at $SPLUNKHOME/etc/apps/ /bin/scripts, but $SPLUNKHOME/bin/scripts is the correct system-wide location listed in the options.

Question 13

Which stats command function provides a count of how many unique values exist for a given field in the result set?

Accepted Answer

A

Explanation: The stats command in Splunk uses various functions to perform calculations on search results. To count the number of unique (or distinct) values for a specific field, the distinctcount() function is used. The dc() function is the officially documented and commonly used alias for distinctcount(). It iterates through the results and returns a count of how many different values appear for the specified field.

Question 14

What is the main requirement for creating visualizations using the Splunk UI?

Accepted Answer

C

Explanation: Splunk visualizations are graphical representations of search results. To create most visualizations, such as charts and graphs, the underlying search must first aggregate and structure the raw event data into a results table. This is accomplished by using transforming commands like stats, chart, timechart, or top. These commands compute statistics and organize the data into the tabular format required by the visualization engine to plot data points, create series, and render the final graphic. Raw, untransformed event data cannot be directly visualized in this manner.

Question 15

Field values are case sensitive.

Accepted Answer

FALSE

Explanation: By default, Splunk searches, including searches on field-value pairs, are case-insensitive. For example, a search for status=error will match events containing status=error, status=ERROR, or status=Error. While there are specific exceptions where case sensitivity is enforced (such as for the metadata fields host, source, and sourcetype), this is not the general rule for all field values. The overarching default behavior of the Search Processing Language (SPL) is case-insensitivity for user-extracted field values.
