Question 46
Which SPL command is used to create a table displaying only the specified fields from events?
A) table
B) stats
C) eval
D) dedup
Answer: A
Explanation:
In Splunk, data often contains multiple fields, some of which are irrelevant for a particular analysis, visualization, or report. A specific SPL command allows analysts to display only selected fields in a structured tabular format. This is particularly useful for presenting data in a clear and concise manner without altering the underlying events or removing them from the search results. For example, analysts may want to show only timestamp, host, user, and status fields from a set of events to focus on the most important information while preparing dashboards, reports, or exportable datasets. The command ensures that only the specified fields appear in the output, improving readability and reducing clutter.
One incorrect command aggregates events to calculate metrics like count, sum, average, or distinct counts. While it produces summaries, it does not simply filter or display selected fields as-is. Another choice evaluates expressions to create new fields or transform existing ones. Though useful for deriving additional data, it does not limit the output to specific fields for display. A third incorrect command removes duplicate events based on field values; it reduces redundancy but does not structure or restrict the columns shown in the output.
The correct command is widely used in operational, security, and business analytics. In operational monitoring, displaying only server, application, and error code fields helps focus on actionable metrics. Security analysts can isolate the timestamp, IP address, and event type for reviewing alerts without distractions. In business analytics, analysts may display only customer ID, transaction ID, and purchase amount to generate concise reports. The command works well in conjunction with other SPL commands, such as sort, dedup, or wher, to refine which events are included in the output.
It also integrates seamlessly with dashboards and reports. By selecting only relevant fields, it improves the clarity of visualizations and tables in panels, enabling decision-makers to focus on key metrics. Unlike aggregation commands, it does not summarize or change data values; it only filters the fields that are displayed. This ensures the original events remain intact for further analysis, making it ideal for exploratory searches or initial data review.
Additionally, the command is essential when exporting datasets to CSV, JSON, or other formats. By displaying only the necessary fields, it reduces file size and ensures that the exported data is meaningful and easy to interpret. Analysts often combine it with time-based filtering, sorting, or deduplication to produce clean and organized tables suitable for reporting or downstream processing.
The command displays only specified fields in a tabular format, improving readability, dashboard clarity, and exportable output. Unlike stats, eval, or dedup, it does not perform calculations, create new fields, or remove duplicate events; it solely structures the output for presentation purposes. It is a foundational tool for focusing on relevant information in Splunk searches and reports.
Therefore, the correct answer is table.
Question 47
Which SPL command is used to calculate the moving average of a numeric field over a specified number of events?
A) movingavg
B) accum
C) stats
D) eval
Answer: A
Explanation:
In Splunk, analyzing trends in numeric data often requires smoothing out fluctuations or noise. A specific SPL command allows analysts to calculate the moving average of a numeric field over a defined window of events. This provides insight into underlying patterns, making it easier to detect trends, spikes, or gradual changes over time. For example, calculating the moving average of CPU usage per server, response times per application, or sales per day enables analysts to identify periods of sustained high activity or performance degradation. The command evaluates each event within the specified window and computes the average for that subset, producing a new field with the calculated moving average.
One incorrect command computes cumulative totals for a numeric field, adding values sequentially across events. While useful for tracking running totals, it does not smooth data or calculate averages over a defined window. Another choice aggregates statistics like count, sum, or average across groups of events. Unlike moving averages, this produces a single summary value rather than calculating averages sequentially across event windows. A third incorrect command evaluates expressions or derives new fields per event, but does not inherently calculate moving averages or account for a defined window of events.
The correct command is widely used in operational, security, and business analytics. In operations, analysts monitor system metrics like CPU usage, memory utilization, or network traffic, and moving averages help reveal trends without being misled by short-term spikes. In security, moving averages of failed login attempts or alert counts allow detection of sustained abnormal activity rather than reacting to occasional anomalies. Business analysts use moving averages of sales, revenue, or customer activity to smooth fluctuations and identify long-term trends or seasonal effects.
It supports window sizes defined by the number of events, allowing flexibility in smoothing granularity. Smaller windows provide sensitivity to rapid changes, while larger windows reveal long-term trends. The command integrates seamlessly with sort and table or chart for visualization, enabling analysts to display smoothed time-series graphs. It also allows combination with eval or where to further refine or transform moving average calculations, ensuring accurate trend analysis.
Using this command improves accuracy in anomaly detection, trend visualization, and predictive analytics. Unlike cumulative sums, general statistics, or basic field derivation, moving averages focus on smoothing numeric trends over a specified number of events, providing a clearer picture of underlying patterns and behaviors.
The command calculates moving averages over a specified number of events, helping to smooth data and reveal trends. It supports flexible window sizes, integrates with visualization commands, and is essential for operational, security, and business analysis of numeric metrics.
Therefore, the correct answer is movingavg.
Question 48
Which SPL command is used to perform horizontal aggregation by one or more fields, producing a multi-dimensional summary table?
A) chart
B) stats
C) timechart
D) table
Answer: A
Explanation:
In Splunk, analysts frequently need to summarize data across multiple dimensions to understand relationships between fields and metrics. A specific SPL command performs horizontal aggregation, grouping events by one or more fields and calculating statistical functions such as count, sum, average, or maximum for each combination. This produces a multi-dimensional summary table, often called a pivot table in other analytics tools, which is particularly useful for operational monitoring, security analysis, and business reporting. For example, analysts can compute total sales by product and region, error counts by host and application, or login attempts by user and source IP.
One incorrect command aggregates events but does not produce a horizontal summary table; it produces single-row summaries for each grouping field. While stats is versatile and powerful for aggregation, it does not automatically format results into a multi-dimensional table suitable for horizontal analysis. Another choice aggregates data over time, creating time-based visualizations; it is not designed for multi-dimensional horizontal summaries. A third incorrect command formats selected fields for display without performing aggregation; it focuses on presentation rather than calculation or multi-dimensional analysis.
The correct command is particularly valuable for operational analytics. For instance, by aggregating error counts per host and per application, analysts can identify high-impact problem areas. In security, combining metrics per user and per event type enables the detection of patterns of suspicious behavior. In business contexts, aggregating revenue or sales per product category and region supports performance tracking, forecasting, and decision-making. Producing a structured multi-dimensional view, it allows analysts to uncover insights that may be hidden in raw event data.
It supports multiple statistical functions and can handle multiple grouping fields simultaneously, allowing complex combinations of metrics and categories. Analysts can further combine it with sort, table, or visualization commands to generate charts, dashboards, or summary reports. The command also supports optional arguments for controlling the display format, top results, and aggregation behavior, increasing flexibility and control over the output.
Using this command ensures efficient analysis of multi-dimensional datasets, accurate reporting, and clear visualization of relationships between fields. Unlike stats, timechart, or table, it focuses on producing horizontal aggregation tables that provide insight into multiple dimensions simultaneously, making it a foundational tool for structured multi-dimensional analysis in Splunk.
The command performs horizontal aggregation across multiple fields, producing a multi-dimensional summary table with statistical metrics. It supports complex grouping, multiple functions, and integration with visualization commands, enabling operational, security, and business analytics.

Question 49
Which SPL command is used to combine the results of two searches based on a common field, similar to a database join?
A) join
B) append
C) stats
D) eval
Answer: A
Explanation:
In Splunk, analysts often need to correlate data from different sources or indexes. A specific SPL command allows combining the results of two searches by matching values in a common field, similar to SQL joins. This enables horizontal merging of datasets, creating a single output where fields from the secondary search are appended to the primary search when the key matches. For example, analysts can join web server logs with user account information using the user ID as the key to enrich event data with additional context, such as department or location. This is essential for operational, security, and business analysis, where cross-referencing datasets provides deeper insights.
One incorrect command simply stacks results from a secondary search beneath the primary search without merging by a key. While it combines datasets, it does not correlate events, so relationships between fields are not preserved. Another choice calculates statistics across events, aggregating values but not merging datasets based on matching fields. It summarizes rather than joins, making it unsuitable for horizontal merging of datasets. A third incorrect command evaluates expressions to create or modify fields within each event; it does not combine events from multiple searches.
The correct command is particularly useful in security, operational, and business contexts. Security analysts can join threat intelligence feeds with firewall logs, correlating IP addresses to known malicious actors. In operations, server metrics can be joined with configuration data to analyze performance issues per configuration type. In business analytics, sales transactions can be joined with customer demographics to enrich the analysis of purchase patterns. By correlating datasets based on a shared field, analysts gain a more comprehensive view, making this command critical for context-aware insights.
It supports one-to-one and one-to-many joins, allowing flexibility in combining datasets. Analysts can specify the fields to include, manage naming conflicts, and control the join type (inner join or left join). Additionally, it can handle subsearches, where the secondary search provides dynamic results that feed into the primary search, enhancing real-time analytics.
Using this command ensures that datasets are enriched with relevant contextual information without losing the event-level details of the primary search. Unlike append, which vertically stacks datasets, or stats and eval, which transform data rather than merge, this command horizontally correlates datasets based on a key field, making it indispensable for cross-source analysis in Splunk.
The command merges datasets from two searches based on a common field, producing a horizontally enriched result. It supports flexible join types, subsearches, and field management, enabling analysts to correlate events across sources. It is essential for operational, security, and business analytics requiring context-aware merging.
Therefore, the correct answer is join.

A) rex
B) eval
C) mvexpand
D) top
Answer: A
Explanation:
In Splunk, many log sources contain multi-line fields, such as stack traces, messages, or JSON content, where critical information may be embedded. A specific SPL command allows analysts to search within these multi-line fields using regular expressions and extract specific content into a new field. This capability is crucial for structuring unstructured data, enabling further analysis, correlation, or reporting. For instance, extracting error codes from stack traces, extracting hostnames from messages, or identifying transaction identifiers embedded within multi-line logs ensures that essential information is accessible for monitoring, alerting, or visualization.
One incorrect command evaluates expressions per event to derive new fields based on arithmetic or string operations. While powerful for calculations and transformations, it does not perform pattern-based extraction within multi-line text fields. Another choice expands multivalue fields into multiple events; it operates on lists rather than extracting patterns from text. A third incorrect command identifies the most frequent values in a dataset but does not perform text extraction.
The correct command is widely used in operational, security, and business contexts. In operational monitoring, extracting error codes or service identifiers from multi-line logs allows teams to quickly identify and analyze incidents. Security analysts can extract IP addresses, usernames, or suspicious patterns from log messages or threat reports for correlation with other events. Business analysts can extract embedded product or customer identifiers from transaction messages for reporting and analysis. By converting unstructured text into structured fields, the command enables precise aggregation, filtering, and visualization.
It supports multiple capturing groups and named fields, allowing simultaneous extraction of several values from a single field. Analysts can apply inline extraction within a search or define persistent field extractions for repeated use. Combined with commands like stats, table, chart, or timechart, extracted fields can be aggregated, visualized, or included in dashboards. Conditional patterns can also be used to selectively extract relevant portions of multi-line content.
Using this command enhances search efficiency, ensures accurate metrics, and enables granular analysis. Unlike eval, mvexpand, or top, it specifically focuses on pattern-based extraction from potentially multi-line text fields, making it indispensable for transforming raw data into actionable information.
The command extracts patterns from multi-line text fields using regular expressions, creating new fields for analysis, correlation, and visualization.

Therefore, the correct answer is rex.
Question 51
Which SPL command is used to calculate the cumulative sum of a numeric field across events while preserving the order of events?
A) accum
B) stats
C) eventstats
D) table
Answer: A
Explanation:
In Splunk, there are scenarios where analysts need to track running totals over time, such as cumulative revenue, ongoing error counts, or sequential activity tracking. A specific SPL command calculates the cumulative sum of a numeric field across events while preserving the original order of events. Each event retains its position in the dataset, and a new field is added showing the running total up to that event. This allows analysts to monitor trends, detect anomalies, or visualize ongoing metrics without losing temporal or event-level context. For example, cumulative login failures per user, ongoing server transaction counts, or total sales revenue over time can be tracked using this command.
One incorrect command aggregates events across groups but does not preserve individual event context or calculate running totals. It summarizes rather than providing sequential accumulation. Another choice calculates statistics and appends aggregated metrics to events, but is not designed for sequential running totals. A third incorrect command displays specified fields in tabular format without performing any aggregation or sequential calculation.
The correct command is widely used in operational, security, and business scenarios. In operations, it can track cumulative system errors or service requests, helping identify persistent issues. Security analysts use it to monitor cumulative failed login attempts or alert occurrences, enabling threshold-based alerting. Business analysts can calculate cumulative sales, customer acquisition, or revenue trends to assess progress toward targets. By maintaining event order, the command ensures that the cumulative metric accurately reflects progression over time.
It works best when events are properly sorted by time or sequence before application. Analysts can combine it with sort, eval, or timechart for visualization and trend analysis. Unlike simple aggregation commands, it produces sequential accumulation while keeping all original events intact, enabling further per-event analysis alongside cumulative metrics.
The command calculates cumulative sums of numeric fields across events while preserving event order. It is essential for tracking ongoing totals, trends, and sequential metrics in operational, security, and business contexts.

Answer: A
Explanation:
In Splunk, field names in event data may be inconsistent, unclear, or too technical for reporting purposes. A specific SPL command allows analysts to rename one or more fields in search results, giving them descriptive, standardized, or easier-to-read names. For example, renaming “src_ip” to “SourceIP” or “user_id” to “UserID” ensures clarity in dashboards, reports, and tables. This command does not modify the underlying events in the index; it only changes field names for the search results output, which helps improve readability and consistency in downstream analysis.
One incorrect command evaluates expressions to create new fields or transform existing ones. While eval is powerful for generating new data, it does not inherently rename existing fields. Another choice formats output in a tabular form by selecting specific fields, improving readability, but not changing field names. A third incorrect command filters events to include or exclude fields; it does not modify field names.
The correct command is particularly useful in operational, security, and business analytics. In operational monitoring, fields representing metrics like CPU usage, memory, or disk activity can be renamed for clarity in dashboards. In security analysis, fields such as “src_ip” or “dest_port” can be renamed to more descriptive names for alert visualization. In business reporting, transaction fields or product identifiers can be renamed to match corporate reporting standards. By standardizing field names, analysts ensure consistent interpretation of metrics across teams and reports.
It allows multiple fields to be renamed simultaneously using a straightforward syntax, making it efficient for large datasets. The command also integrates seamlessly with table, stats, chart, and timechart to produce user-friendly dashboards or visualizations. Analysts can combine it with dedup, eval, or sort for more advanced transformations while maintaining clear field names.
Using this command ensures that dashboards, reports, and visualizations remain intuitive and accessible. Unlike eval, table, or fields, which either create new fields, format output, or select fields, rename focuses solely on altering field names in the search result, without affecting values or data structure. It helps create polished outputs for stakeholders and avoids confusion caused by technical or inconsistent field names. The command renames one or more fields in search results, improving clarity, consistency, and readability. It is widely used in operational, security, and business contexts for dashboards, reports, and analytics, providing clear and standardized field labels without modifying underlying events.
Therefore, the correct answer is rename.
Question 53
Which SPL command is used to calculate the percentage of each value of a field relative to the total count?
A) eventstats with count and eval
B) top
C) stats count
D) table
Answer: A
Explanation:
In Splunk, analysts often need to calculate proportions or percentages to understand the distribution of data relative to the total. A specific combination of SPL commands allows this by first calculating the total count using eventstats and then applying eval to compute the percentage for each value of a field. For example, calculating the percentage of events per error type, per user, or per product category helps visualize dominance, frequency, or relative impact within a dataset. This approach ensures that each event retains context while being enriched with proportional information for better analysis.
One incorrect command displays the most frequent values of a field but does not calculate precise percentages across all events. Another choice simply counts events by field value, providing totals but not normalized percentages relative to the total dataset. A third incorrect command formats fields for presentation; it does not perform counting or proportional calculations.
The correct command is widely applicable in operational, security, and business contexts. In operational monitoring, analysts can compute the percentage of errors by host or service relative to total errors, aiding prioritization and troubleshooting. Security analysts can calculate the percentage of login failures per user or source IP relative to the total, which is crucial for identifying abnormal behavior. In business analytics, percentages of product sales per category or customer engagement relative to total transactions provide actionable insights for marketing or inventory decisions.
Eventstats is used to calculate the total count across all events and append it to each event as a new field. Eval is then applied to compute the percentage by dividing the count of each specific value by the total count and multiplying by 100. This combination preserves individual events while providing proportional context, allowing downstream commands like table, chart, or timechart to visualize relative distributions effectively.
Using this approach ensures accurate representation of proportions and prevents misinterpretation caused by raw counts alone. Unlike top, stats, or table alone, which either display frequencies, aggregate totals, or format fields, this method provides normalized percentages while maintaining event-level context. Analysts can apply additional filters or grouping fields to refine percentages across specific dimensions, enhancing precision and insight.
eventstats with count and eval calculates percentages of field values relative to the total count, preserving event-level data and providing normalized insight. It is essential for operational, security, and business analytics when understanding relative distributions or proportions of events, metrics, or transactions.
Therefore, the correct answer is eventstats with count and eval.
Question 54
Which SPL command is used to combine multiple values of a field into a single multivalue field?
A) mvcombine
B) mvexpand
C) stats
D) eval

Explanation:
In Splunk, some analyses require consolidating multiple values from a single field across events into one multivalue field. A specific SPL command allows analysts to achieve this by combining values from multiple events into a single multivalue field. This is particularly useful when tracking all related items associated with a particular key, such as combining all error codes for a host, all product IDs in a transaction, or all IP addresses associated with a user. By consolidating values, it simplifies downstream processing, aggregation, and visualization.
One incorrect command performs the opposite operation by splitting multivalue fields into individual events. While mvexpand is useful for per-value analysis, it does not combine values. Another choice aggregates events and produces statistical summaries, but does not create a multivalue field from multiple values of a field. A third incorrect command evaluates expressions to create or transform a field, but does not automatically consolidate multiple event values into a single multivalue field.
The correct command is widely used in operational, security, and business analytics. In operations, combining all error codes for a host into a single multivalue field provides a consolidated view of issues without repeating events. Security analysts can combine all IP addresses accessed by a user or associated with an alert, simplifying correlation and investigation. In business analytics, consolidating all products purchased by a customer in a single field supports comprehensive customer behavior analysis.
It allows specifying a delimiter for the combined values and works seamlessly with stats, eval, or table for further manipulation and visualization. The resulting multivalue field can be expanded later if needed, giving flexibility for both aggregation and per-value analysis. This command enhances reporting, dashboard clarity, and analytical efficiency by reducing redundancy and consolidating related information.
Unlike mvexpand, stats, or eval, which split, aggregate, or manipulate individual events, this command focuses specifically on horizontal consolidation into a multivalue field. It ensures that analysts have a compact and manageable representation of related data, improving workflow efficiency and analytical insight.
The command combines multiple values of a field into a single multivalue field, providing consolidated and manageable datasets.

A) where
B) eval
C) search
D) table
Answer: A
Explanation:
In Splunk, filtering events based on specific conditions is a fundamental part of refining search results. A particular SPL command allows analysts to apply logical or comparative conditions directly to fields in events to determine which events should be included in the output. This command supports Boolean operators such as AND, OR, and NOT, as well as comparison operators like =, !=, >, <, >=, and <=. For example, an analyst might filter events where the status code equals 500, where CPU usage exceeds a threshold, or where the error message contains a specific keyword. This precise filtering ensures that only relevant events are analyzed, reducing noise and improving search efficiency.
One incorrect command evaluates expressions to create new fields or transform existing ones. While eval is versatile, it does not inherently filter events; it only calculates values or derives new fields per event. Another choice performs searches but generally filters across the entire pipeline rather than applying field-specific logical conditions in-line with event processing. A third incorrect command formats events as a table of selected fields for display purposes, but does not filter events based on conditional logic.
The correct command is widely used in operational, security, and business analytics. In operational monitoring, filtering for events where CPU usage is above a threshold allows teams to focus on performance issues. In security, analysts can filter logs for events where login attempts fail or where source IPs belong to a certain range, enabling targeted incident investigation. In business analytics, filtering for transactions above a certain dollar amount or customers from a specific region allows precise reporting and analysis.
This command can be combined with eval to create conditional fields and then filter based on those derived values. It is also compatible with other commands such as stats, chart, or table, allowing filtered events to be further summarized or visualized. By applying filtering at the search stage, it reduces unnecessary processing of irrelevant events downstream, improving both performance and clarity.
Using this command ensures accurate and efficient data analysis by allowing targeted inclusion of events based on field-specific criteria. Unlike eval, search, or table, which focus on transformation, broad searching, or formatting, this command applies conditional logic directly to the events themselves, maintaining the integrity and context of the filtered dataset.
The command filters events based on conditions applied to fields, supporting Boolean and comparative operators. It is essential in operational, security, and business contexts for targeted analysis, precise reporting, and efficient search workflows.
Therefore, the correct answer is where.

A) split
B) rex
C) eval
D) mvcombine
Answer: A
Explanation:
In Splunk, extracting specific portions of field values is often required for structured analysis. A specific SPL command allows analysts to split a field into multiple components based on a defined delimiter, such as a comma, space, colon, or semicolon. This command converts a single field into a multivalue field, where each value represents a portion of the original text. For instance, splitting a comma-separated list of product IDs, a colon-separated timestamp, or a space-separated hostname allows analysts to normalize data for filtering, aggregation, or visualization. Using delimiters, it avoids the complexity of regular expressions while achieving precise extraction of structured components.
One incorrect command uses regular expressions for pattern-based extraction. While flexible, regex can be overkill for simple delimiter-based splits and requires pattern knowledge. Another choice evaluates expressions or derives new fields, but does not automatically split a field into multiple values. A third incorrect command combines multiple values into a single multivalue field, which is the opposite of splitting.
The correct command is widely used in operational, security, and business analytics. In operational contexts, splitting a field containing multiple error codes or log parameters allows detailed per-value analysis. In security, analysts can split URLs, IP ranges, or event tags to monitor each component separately. In business, splitting transaction items, customer attributes, or product categories allows aggregation, filtering, and reporting based on individual components rather than the concatenated field.
It produces a multivalue field that can be expanded later using mvexpand for event-level analysis. It also works with stats, chart, timechart, and eval to facilitate further calculations or visualization. Analysts can specify the delimiter and manage cases with variable-length values or missing components, ensuring robust data normalization.
Using this command improves efficiency, reduces complexity, and enables analysts to work with individual components of a field without creating complex regex patterns. Unlike rex, eval, or mvcombine, it focuses specifically on splitting fields into multiple values based on simple delimiters, making it a practical and straightforward tool for structured extraction.

C) stats
D) eval
Answer: A
Explanation:
In Splunk, analysts often need to combine results from multiple searches into a single dataset for comprehensive analysis. A specific SPL command allows appending the results of a secondary search to the primary search, stacking datasets vertically. This means that events from the secondary search appear below events from the primary search, without merging based on fields. This approach is useful for combining datasets from different indexes, time ranges, or criteria, allowing comparison, trend analysis, or consolidated reporting. For example, appending logs from two hosts, sales data from two periods, or security alerts from multiple sources enables a complete dataset for analysis.
One incorrect command merges datasets horizontally by matching fields. While this is useful for correlation, it does not simply stack events. Another choice calculates aggregated statistics, producing summarized datasets rather than combining raw events. A third incorrect command evaluates expressions or derives new fields without combining searches, focusing on transformation rather than appending.
The correct command is widely used in operational, security, and business analytics. In operations, combining logs from multiple servers into one dataset allows holistic monitoring. In security, combining alerts from multiple detection systems provides a unified view of potential threats. In business analytics, appending datasets from different regions, departments, or product lines enables consolidated reporting and analysis.
It supports specifying the secondary search inline or referencing saved searches, providing flexibility in search composition. Analysts can combine it with dedup, table, sort, or chart to refine the resulting stacked dataset. Although it stacks events vertically, it preserves all original event fields and values, maintaining the integrity and completeness of the data.
Using this command ensures comprehensive datasets for analysis, reporting, and visualization. Unlike join, stats, or eval, which merge horizontally, summarize, or transform, this command vertically combines event sets, providing a simple and effective way to consolidate results from multiple searches.
The command appends the results of one search to another, stacking events vertically. It is essential to combine datasets from different sources, time periods, or criteria in operational, security, and business analytics, preserving all original event information.
Therefore, the correct answer is append.
Question 58
Which SPL command is used to expand a multivalue field into individual events, creating one event per value?
A) mvexpand
B) mvcombine
C) eval
D) table
Answer: A
Explanation:
In Splunk, multivalue fields often store multiple discrete values within a single event. While this is useful for consolidating information, some analyses require examining each value individually. A specific SPL command allows analysts to expand a multivalue field so that each value becomes a separate event. This transformation is essential for granular analysis, aggregation, visualization, or reporting. For instance, if a field contains multiple IP addresses accessed by a user, expanding the field generates separate events for each IP address, making it possible to calculate per-IP statistics or monitor individual activity.
One incorrect command combines multiple values of a field into a single multivalue field, which is the opposite of expanding. Another choice evaluates expressions to create new fields or transform existing ones, but does not split multivalue fields into multiple events. A third incorrect command formats selected fields for display in a table but does not alter the structure of events or split values.
The correct command is widely used in operational, security, and business analytics. In operations, expanding multivalue fields containing multiple error codes per host allows detailed tracking and troubleshooting. Security analysts can expand lists of IP addresses, user sessions, or threat indicators to analyze each element individually, facilitating correlation, alerting, and incident investigation. In business analytics, expanding fields with multiple purchased product IDs per transaction allows calculation of per-item sales metrics or inventory analysis.
It integrates seamlessly with aggregation and visualization commands such as stats, chart, timechart, or table. Analysts can combine it with sort, dedup, or eval for further processing while maintaining one-to-one event relationships. The command preserves all other fields in the event, ensuring that contextual information remains available while focusing analysis on individual multivalue elements.
Using this command improves precision in reporting, anomaly detection, and trend analysis. Unlike mvcombine, which merges values into one field, or table, which only formats output, mvexpand transforms the dataset into a granular format suitable for per-value metrics and visualization. It is essential for workflows where multivalue fields must be broken down for accurate statistical or operational insight.
The command expands multivalue fields into individual events, enabling per-value analysis while preserving context. It is critical in operational, security, and business analytics when granular inspection of each value is required, facilitating aggregation, visualization, and detailed reporting.
Therefore, the correct answer is mvexpand.

Question 60
Which SPL command is used to find the most common values of a field and their frequency?
A) top
B) stats
C) table
D) dedup
Answer: A
Explanation:
In Splunk, identifying the most frequent occurrences of a field is a common analytical requirement. A specific SPL command calculates the most common values for a field and their corresponding frequencies, providing insight into dominant trends, recurring events, or patterns. For example, identifying the top error codes, most accessed URLs, or most active users helps analysts prioritize monitoring, investigate issues, or generate business insights. This command returns a concise summary of the top N values with counts and percentages, which can be visualized or reported directly.
One incorrect command aggregates data across events but produces broader statistics, such as count, sum, or average, rather than identifying the most common individual values. Another choice formats selected fields into a table, but does not analyze frequency. A third incorrect command removes duplicate events, reducing redundancy without summarizing common occurrences.
The correct command is widely used in operational, security, and business analytics. In operations, analyzing the top error codes or log sources allows teams to focus on the most impactful issues. In security, identifying the most frequently used source IPs or user accounts can highlight normal behavior or potential malicious activity. In business analytics, determining the top-selling products, top-performing stores, or most frequent customer interactions helps inform decision-making, marketing strategies, and inventory planning.
It supports options to limit the number of values displayed, calculate percentages, and include rare or additional values. Analysts can combine it with sort, table, or chart to create dashboards and reports, visualizing patterns effectively. Unlike stats, which requires specifying aggregation functions, this command simplifies the process of frequency analysis, providing an immediate view of dominant values in a dataset.
Using this command ensures efficient identification of patterns, hotspots, or priorities. Unlike stats, table, or dedup, which summarize, format, or filter data, this command focuses specifically on frequency analysis, making it essential for monitoring, anomaly detection, and business intelligence. The command identifies the most common values of a field and calculates their frequency, enabling operational, security, and business insights. It simplifies pattern detection, supports visualization, and highlights key trends in datasets.
Therefore, the correct answer is top.
