How is a muitlvalue Add treated from product-"a, b, c, d"?
- A. . . . | makemv delim="," product
- B. . . . | makemv delim{product, ","}
- C. . . . | mvexpand product
- D. . . . | eval mvexpand{makemv{product, ","})
正解：A
解説：
To treat a multivalue field product="a, b, c, d" in Splunk, the correct command is ...| makemv delim="," product (Option D).The makemv command with the delim argument specifies the delimiter (in this case, a comma) to split the field values into a multivalue field. This allows for easier manipulation and analysis of each value within the product field as separate entities.
質問 # 33
Which of the following has a schema or structure embedded in the data itself?
- A. Unstructured data
- B. Embedded data
- C. Self-describing data
- D. Dark data
正解：C
解説：
Self-describing data (Option D) refers to data that includes information about its own structure or schema within the data itself. This characteristic makes it easier to understand and process the data because the structure and meaning of the data are embedded with the data, reducing the need for external definitions or mappings. Examples of self-describing data formats include JSON and XML, where elements and attributes describe the data they contain.
質問 # 34
What happens to panels with post-processing searches when their base search Is refreshed?
- A. Nothing happens to the panels.
- B. The parcels are deleted.
- C. The panels are only refreshed If they have also been configured.
- D. The panels are refreshed automatically.
正解：D
解説：
When the base search of a dashboard panel with post-processing searches is refreshed, the panels with these post-processing searches are refreshed automatically (Option C). Post-processing searches inherit the scope and results of the base search, and when the base search is updated or rerun, the post-processed results are recalculated to reflect the latest data.
質問 # 35
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 # 36
Which statement about the coalesce function is accurate?
- A. It can take a maximum of two arguments.
- B. It can return null or non-null values.
- C. It can be used to create a new field in the results set.
- D. It can take only a single argument.
正解：C
解説：
The coalesce function in Splunk is used to evaluate each argument in order and return the first non-null value.
This function can be used within an eval expression to create a new field in the results set, which will contain the first non-null value from the list of fields provided as arguments to coalesce. This makes it particularly useful in situations where data may be missing or inconsistently populated across multiple fields, as it allows for a fallback mechanism to ensure that some value is always presented.

- A. stats, target, change, and clear
- B. eval, link, change, and clear
- C. eval, link, set, and unset
- D. stats, target, set, and unset
正解：B
解説：
The four types of event actions in Splunk are eval, link, change, and clear (Option C). These actions can be used in dashboard panel configurations to dynamically interact with or manipulate event data based on user inputs or other criteria. Eval is used for calculating fields, link for creating hyperlinks, change for modifying field values, and clear for removing field values or other data elements.
質問 # 40
Which element attribute is required for event annotation?
- A. <search type=$annotation$>
- B. <search type="event_annotation">
- C. <search type="annotation">
- D. <search style="annotation">
正解：C
解説：
In Splunk dashboards, event annotations are used to add informative overlays on timeline visualizations to mark significant events. The required element attribute to define an event annotation within a dashboard panel is <search type="annotation"> (Option D). This attribute specifies that the search within this element is intended to generate annotations, which are then overlaid on the timeline based on the time and information provided by the search results.
質問 # 41
If a search contains a subsearch, what is the order of execution?
- A. The outer search executes first.
- B. The inner search executes first.
- C. The two searches are executed in parallel.
- D. The order of execution depends on whether either search uses a stats command.
正解：B
解説：
In a Splunk search containing a subsearch, the inner subsearch executes first. The result of the subsearch is then passed to the outer search, which often depends on the results of the inner subsearch to complete its execution.
質問 # 42
What does using the tstats command with summariesonly=false do?
- A. Returns results from only non-summarized data.
- B. Returns results from both summarized and non-summarized data.
- C. Prevents use of wildcard characters in aggregate functions.
- D. Returns no results.
正解：B
解説：
Using the tstats command with summariesonly=false instructs Splunk to return results from both summarized (accelerated) data and non-summarized (raw) data. This can be useful when you need a comprehensive view of the data that includes both the high-performance summaries provided by data model acceleration and the detailed granularity of raw data.
質問 # 43
When possible, what is the best choice for summarizing data to improve search performance?
- A. Data model acceleration
- B. Us the fieldsummary command.
- C. Report acceleration
- D. Summary indexing

How is regex passed to the makemv command?
- A. It is specified by the tokenizer argument.
- B. It is specified by the delim argument.
- C. makemv must be preceded by the erex command.
- D. makemv must be preceded by the rex command.
正解：B
解説：
The regex is passed to the makemv command in Splunk using the delim argument. This argument specifies the delimiter used to split a single string field into multiple values, effectively creating a multivalue field.
質問 # 45
Which of the following is not a common default time field?
- A. date minute
- B. date_zone
- C. date_day
- D. date_year
正解：B
解説：
In Splunk, common default time fields include date_minute, date_year, and date_day, which represent the minute, year, and day parts of event timestamps, respectively. date_zone (Option A) is not recognized as a common default time field in Splunk. The platform typically uses fields like _time and various date_* fields for time-related information but does not use date_zone as a standard time field.
