質問 # 25
When using a nested search macro, how can an argument value be passed to the inner macro?
- A. An argument cannot be used with an inner nested macro.
- B. An argument cannot be used with an outer nested macro.
- C. The argument value must be specified in the outer macro.
- D. The argument value may be passed to the outer macro.
正解:D
解説:
When using a nested search macro in Splunk, an argument value can be passed to the inner macro by specifying the argument in the outer macro's invocation (Option A). This allows the outer macro to accept arguments from the user or another search command and then pass those arguments into the inner macro, enabling dynamic and flexible macro compositions that can adapt based on input parameters.
質問 # 26
Which command processes a template for a set of related fields?
- A. bin
- B. xyseries
- C. untable
- D. foreach
正解:D
解説:
The foreach command applies a processing step to each field in a set of related fields. It allows repetitive operations to be applied to multiple fields in one go, streamlining tasks across several fields.
質問 # 27
What is returned when Splunk finds fewer than the minimum matches for each lookup value?
- A. The first match unless the time_field attribute is specified.
- B. The default value NULL until the minimum match threshold is reached.
- C. Only the first match.
- D. The default match value until the minimum match threshold Is reached.
正解:B
解説:
When Splunk's lookup feature finds fewer than the minimum matches specified for each lookup value, it returns the default value NULL for those unmatched entries until the minimum match threshold is reached (Option A). This behavior ensures that lookups return consistent and expected results, even when the available data does not meet the specified criteria for a minimum number of matches.
質問 # 28
How can the inspect button be disabled on a dashboard panel?
- A. Set link.inspect .visible to 0
- B. Set inspect.link.disabled to 1
- C. Set link.inspectSearch.visible too
- D. Set link.search.disabled to 1
正解:A
解説:
To disable the inspect button on a dashboard panel in Splunk, you can set the link.inspect.visible attribute to 0 (Option B) in the panel's source code. This attribute controls the visibility of the inspect button, and setting it to 0 hides the button, preventing users from accessing the search inspector for that panel.
質問 # 29
What type of drilldown passes a value from a user click into another dashboard or external page?
- A. Contextual
- B. Visualization
- C. Event
- D. Dynamic
正解:A
解説:
Contextual drilldown (Option D) is the type of drilldown that allows passing a value from a user click (e.g., from a table row or chart element) into another dashboard or an external page. This feature enables the creation of interactive dashboards where clicking on a specific element dynamically updates another part of the dashboard or navigates to a different page with relevant information, using the clicked value as a context for the subsequent view.
質問 # 30
Which of the following Is valid syntax for the split function?
- A. ...| eval split (phone-Number, "_", areaCodes)
- B. ...| eval areaCodes = split (phonNumber, "_"
- C. ...| eval split phoneNUmber by "_" as areaCodes.
- D. ...| eval phoneNumber split("-", 3, areaCodes)
正解:B
解説:
The valid syntax for using the split function in Splunk is ... | eval areaCodes = split(phoneNumber, "_") (Option B). The split function divides a string into an array of substrings based on a specified delimiter, in this case, an underscore. The resulting array is stored in the new field areaCodes.
質問 # 31
Which search generates a field with a value of "hello"?
- A. | Makeresults field-''hello''
- B. | Makeresults | fields''hello''
- C. | Makeresults | eval field =make{''hello''}
- D. | Makeresults | eval field-''hello''
正解:D
解説:
To generate a field with a value of "hello" using the makeresults command in Splunk, the correct syntax is | makeresults | eval field="hello" (Option C). The makeresults command creates a single event, and the eval command is used to add a new field (named "field" in this case) with the specified value ("hello"). This is a common method for creating sample data or for demonstration purposes within Splunk searches.
質問 # 32
When would a distributable streaming command be executed on an Indexer?
- A. If all preceding search commands are executed on the Indexer.
- B. If all preceding search commands are executed on me indexer, and a streamstats command is used.
- C. If some of the preceding search commands are executed on the indexer, and a Timerchart command is used.
- D. If any of the preceding search commands are executed on the search head.
正解:A
解説:
A distributable streaming command would be executed on an indexer if all preceding search commands are executed on the indexer (Option C). Distributable streaming commands are designed to be executed where the data resides, reducing data transfer across the network and leveraging the processing capabilities of indexers.
This enhances the overall efficiency and performance of Splunk searches, especially in distributed environments.
質問 # 33
Which of the following best describes the process for tokenizing event data?
- A. The event Cats is broken up by values in the punch field.
- B. The event data has all punctuation stripped out and is then space delinked.
- C. The event data is broken up by a series of user-defined regex patterns.
- D. The event data is broken up by major breaker and then broken up further by minor breakers.
正解:D
解説:
The process for tokenizing event data in Splunk is best described as breaking the event data up by major breakers and then further breaking it up by minor breakers (Option B). Major breakers typically identify the boundaries of events, while minor breakers further segment the event data intofields. This hierarchical approach to tokenization allows Splunk to efficiently parse and structure the incoming data for analysis.
質問 # 34
Which commands can run on both search heads and indexers?
- A. Transforming commands
- B. Centralized streaming commands
- C. Distributable streaming commands
- D. Dataset processing commands
正解:C
解説:
Distributable streaming commands operate on each event independently and can be distributed across indexers for parallel execution, improving search efficiency and scalability.
質問 # 35
Which is a regex best practice?
- A. Avoid backtracking.
- B. Use complex expressions rather than simple ones.
- C. Use * rather than +.
- D. Use greedy operators (.*) instead of non-greedy operators (.*?).
正解:A
解説:
One of the best practices in regex is to avoid backtracking, which can degrade performance by revisiting parts of the input multiple times. Optimizing regex patterns to prevent unnecessary backtracking improves efficiency, especially when dealing with large datasets.
質問 # 36
How can the inspect button be disabled on a dashboard panel?
- A. Set inspect.link.disabled to 1
- B. Set link.inspectSearch.visible to 0
- C. Set link.search.disabled to 1
- D. Set link.inspect.visible to 0
正解:D
解説:
To disable the inspect button on a dashboard panel, set the link.inspect.visible attribute to 0. This hides the button, preventing users from accessing the search inspector for that panel.
質問 # 37
When using the bin command, which argument sets the bin size?
- A. volume
- B. span
- C. mazDataSizeMB
- D. max
正解:B
解説:
When using the bin command in Splunk, the span argument is used to set the size of each bin (Option D). The span argument determines the granularity or width of each bin when segmenting data over a time range or numerical field, which is essential for time series analysis, histogram generation, or other aggregated data visualizations.
質問 # 38
Which of the following are potential string results returned by the typeof function?
- A. Number, String, Null
- B. True, False, Unknown
- C. Field, Value, Lookup
- D. Number, String, Bool
正解:A
解説:
The typeof function in Splunk returns a string representing the data type of the evaluated expression. The possible results include "Number", "String", and "Null".
質問 # 39
Which of the following best describes the process for tokenizing event data?
- A. The event data has all punctuation stripped out and is then space-delimited.
- B. The event data is broken up by major breakers and then broken up further by minor breakers.
- C. The event data is broken up by values in the punch field.
- D. The event data is broken up by a series of user-defined regex patterns.
正解:B
解説:
The process for tokenizing event data in Splunk involves breaking the event data up by major breakers (which typically identify the boundaries of events) and further breaking it up by minor breakers (which segment the event data into fields). This hierarchical approach allows Splunk to efficiently parse and structure the data.

Which of the following is not a common default time field?
- A. date_zone
- B. date_day
- C. date_minute
- D. date_year
正解:A
解説:
Fields like date_minute, date_year, and date_day are common default time fields in Splunk, while date_zone is not typically a default field for time-related data.
質問 # 41
When using the bin command, which argument sets the bin size?
- A. volume
- B. span
- C. max
- D. maxDataSizeMB
正解:B
解説:
In Splunk, the span argument is used to set the size of each bin when using the bin command, determining the granularity of segmented data over a time range or numerical field.
