質問 # 115
Given the macro definition below, what should be entered into the Name and Arguments fileds to correctly configured the macro?
- A. The macro name issessiontrackerand the arguments are$action$, $JESSIONID$.
- B. The macro name issessiontracker(2)and the Arguments are$action$, $JESSIONID$.
- C. The macro name issessiontrackerand the arguments areaction, JESSIONID.
- D. The macro name issessiontracker(2)and the arguments areaction, JESSIONID.
正解：D
解説：
Reference:https://docs.splunk.com/Documentation/Splunk/8.0.3/Knowledge/Definesearchmacros The macro definition below shows a macro that tracks user sessions based on two arguments: action and JSESSIONID.
sessiontracker(2)
The macro definition does the following:
It specifies the name of the macro as sessiontracker. This is the name that will be used to execute the macro in a search string.
It specifies the number of arguments for the macro as 2. This indicates that the macro takes two arguments when it is executed.
It specifies the code for the macro asindex=main sourcetype=access_combined_wcookie action=$action$ JSESSIONID=$JSESSIONID$ | stats count by JSESSIONID. This is the search string that will be run when the macro is executed. The search string can contain any part of a search, such as search terms, commands, arguments, etc. The search string can also include variables for the arguments using dollar signs around them.
In this case, action and JSESSIONID are variables for the arguments that will be replaced by their values when the macro is executed.
Therefore, to correctly configure the macro, you should enter sessiontracker as the name and action, JSESSIONID as the arguments. Alternatively, you can use sessiontracker(2) as the name and leave the arguments blank.
質問 # 116
Which of the following search modes automatically returns all extracted fields in the fields sidebar?
- A. Verbose
- B. Smart
- C. Fast
正解：A
解説：
The search modes determine how Splunk processes your search and displays your results2. There are three search modes: Fast, Smart and Verbose2. The search mode that automatically returns all extracted fields in the fields sidebar is Verbose2. The Verbose mode shows all the fields that are extracted from your events, including default fields, indexed fields and search-time extracted fields2. The fields sidebar is a panel that shows the fields that are present in your search results2. Therefore, option C is correct, while options A and B are incorrect because they are not search modes that automatically return all extracted fields in the fields sidebar.

質問 # 118
What will you learn from the results of the following search? sourcetype=cisco_esa | transaction mid, dcid,
icid | timechart avg(duration)
- A. The average time for each event within each transaction
- B. The average time elapsed during each transaction for all transactions
- C. The average time between each transaction
正解：B
質問 # 119
The timechart command is an example of which of the following command types?
- A. Generating
- B. Statistical
- C. Orchestrating
- D. Transforming
正解：D
解説：
Explanation
The correct answer is B. Transforming.
The explanation is as follows:
The timechart command is a Splunk command that creates a time series chart with corresponding table of statistics12.
A timechart is a statistical aggregation applied to a field to produce a chart, with time used as the X-axis1. You can specify a split-by field, where each distinct value of the split-by field becomes a series in the chart1.
Transforming commands are commands that change the format of the search results into a data structure that can be easily visualized3. Transforming commands often use stats functions to aggregate and summarize data3.
Therefore, the timechart command is an example of a transforming command, as it transforms the search results into a chart and a table using stats functions123.
質問 # 120
Which of the following statements describes calculated fields?
- A. Calculated fields are a shortcut for repetitive and complex eval commands.
- B. Calculated fields are only used on fields added by lookups.
- C. Calculated fields automatically calculate the simple moving average for indexed fields.
- D. Calculated fields are a shortcut for repetitive and complex calc commands.
正解：A
質問 # 121
Which one of the following statements about the search command is true?
- A. It behaves exactly like search strings before the first pipe.
- B. It does not allow the use of wildcards.
- C. It can only be used at the beginning of the search pipeline.
- D. It treats field values in a case-sensitive manner.
正解：A
質問 # 122
Which of the following statements describe the search below? (select all that apply) Index=main I transaction clientip host maxspan=30s maxpause=5s
- A. The first and last events are no more than 5 seconds apart.
- B. Events in the transaction occurred within 5 seconds.
- C. The first and last events are no more than 30 seconds apart.
- D. It groups events that share the same clientip and host.
正解：B、C、D
解説：
The search below groups events by two or more fields (clientip and host), creates transactions with start and end constraints (maxspan=30s and maxpause=5s), and calculates the duration of each transaction.
index=main | transaction clientip host maxspan=30s maxpause=5s
The search does the following:
It filters the events by the index main, which is a default index in Splunk that contains all data that is not sent to other indexes.
It uses the transaction command to group events into transactions based on two fields: clientip and host. The transaction command creates new events from groups of events that share the same clientip and host values.
It specifies the start and end constraints for the transactions using the maxspan and maxpause arguments. The maxspan argument sets the maximum time span between the first and last events in a transaction. The maxpause argument sets the maximum time span between any two consecutive events in a transaction. In this case, the maxspan is 30 seconds and the maxpause is 5 seconds, meaning that any transaction that has a longer time span or pause will be split into multiple transactions.
It creates some additional fields for each transaction, such as duration, eventcount, startime, etc. The duration field shows the time span between the first and last events in a transaction.
質問 # 123
Which of the following statements describes this search?
sourcetype=access_combined I transaction JSESSIONID | timechart avg (duration)
- A. This is a valid search and will display a stats table showing the maximum pause among transactions.
- B. This is a valid search and will display a timechart of the average duration, of each transaction event.
- C. No results will be returned because the transaction command must include the startswith and endswith options.
- D. No results will be returned because the transaction command must be the last command used in the search pipeline.
正解：B
質問 # 124
Which field will be used to populate the field if the productName and product:d fields have values for a given event?
| eval productINFO=coalesco(productName,productid)
- A. The value for the field because it appears second.
- B. Neither field value will be used and the field will be assigned a NULL value for the given event.
- C. Both field values will be used and the product INFO field will become a multivalue field for the given event.
- D. The value for the productName field because it appears first.
正解：D
解説：
The correct answer is B. The value for the productName field because it appears first.
The coalesce function is an eval function that takes an arbitrary number of arguments and returns the first value that is not null. A null value means that the field has no value at all, while an empty value means that the field has a value, but it is "" or zero-length1.
The coalesce function can be used to combine fields that have different names but represent the same data, such as IP address or user name. The coalesce function can also be used to rename fields for clarity or convenience2.
The syntax for the coalesce function is:
coalesce(<field1>,<field2>,...)
The coalesce function will return the value of the first field that is not null in the argument list. If all fields are null, the coalesce function will return null.
For example, if you have a set of events where the IP address is extracted to either clientip or ipaddress, you can use the coalesce function to define a new field called ip, that takes the value of either clientip or ipaddress, depending on which is not null:
| eval ip=coalesce(clientip,ipaddress)
In your example, you have a set of events where the product name is extracted to either productName or productid, and you use the coalesce function to define a new field called productINFO, that takes the value of either productName or productid, depending on which is not null:
| eval productINFO=coalesce(productName,productid)
If both productName and productid fields have values for a given event, the coalesce function will return the value of the productName field because it appears first in the argument list. The productid field will be ignored by the coalesce function.
Therefore, the value for the productName field will be used to populate the productINFO field if both fields have values for a given event.

質問 # 125
Which search string would only return results for an event type called success ful_purchases?
- A. successful_purchases
- B. event type-success ful_purchases
- C. tag=success ful_purchases
- D. Event Type:: successful purchases
正解：A
解説：
Explanation
This is because event types are added to events as a field named eventtype, and you can use this field as a search term to find events that match a specific event type. For example, eventtype=successful_purchases returns all events that have been categorized as successful purchases by the event type definition. The other options are incorrect because they either use a different field name (tag), a different syntax (Event Type:: or event type-), or have a typo (success ful_purchases). You can learn more about how to use event types in searches from the Splunk documentation1.
質問 # 126

- B. Creates a table of the total count of mysterymeat corndogs split by user.
- C. Creates a table that groups the total number of users by vegetarian corndogs.
- D. Creates a table with the count of all types of corndogs eaten split by user.
正解：B
質問 # 127
When is a GET workflow action needed?
- A. To define how events flow from forwarders to indexes.
- B. To retrieve information from an external resource.
- C. To use field values to perform a secondary search.

正解：B
質問 # 128
Calculated fields can be based on which of the following?
- A. Fields generated from a search string
- B. Extracted fields
- C. Output fields for a lookup
- D. Tags
正解：B
解説：
"Calculated fields can reference all types of field extractions and field aliasing, but they cannot reference lookups, event types, or tags."
質問 # 129
Which of the following is true about data model attributes?
- A. They cannot be edited if inherited from a parent dataset.
- B. They can be added to a dataset from search time field extractions.
- C. They can only be added into a root search dataset.
- D. They cannot be created within the data model.
正解：B
解説：
Data model attributes are fields that are added to a dataset from search time field extractions, calculated fields, lookups, or aliases. They can be created within the data model editor or inherited from a parent dataset. They can be edited or removed unless they are required by the data model. They can be added to any type of dataset, not just root search datasets.ReferencesSee About data models, [Define data model attributes], and [Edit data model datasets] in the Splunk Documentation.
質問 # 130

- A. Determined automatically based on the data source.
- B. Turned on
- C. Determined automatically based on the sourcetype.
- D. Turned off
正解：A
質問 # 131
Which of the following actions can the eval command perform?
- A. Group transactions by one or more fields.
- B. Create or replace an existing field.
- C. Save SPL commands to be reused in other searches.
- D. Remove fields from results.
正解：B
解説：
The eval command is used to create new fields or modify existing fields based on an expression2. The eval
command can perform various actions such as calculations, conversions, string manipulations and more2. One
of the actions that the eval command can perform is to create or replace an existing field with a new value
based on an expression2. For example, | eval status=if(status="200","OK","ERROR") will create or replace the
status field with either OK or ERROR depending on the original value of status2. Therefore, option B is
correct, while options A, C and D are incorrect because they are not actions that the eval command can
perform.
質問 # 132
Why would the following search produce multiple transactions instead of one?
- A. The transaction and commands cannot be used together.
- B. The transaction command has a limit of 1000 events per transaction.
- C. The maxspan option is not included.
- D. The stats list () function is used.
正解：B
解説：
Explanation
The correct answer is B. The transaction command has a limit of 1000 events per transaction.
The transaction command is used to group events that share some common values into a single record, called a transaction. A transaction can span multiple events and multiple sources, and can be useful for correlating events that are related but not contiguous1.
However, the transaction command has some limitations, one of which is that it can only group up to 1000 events per transaction. This means that if there are more than 1000 events that match the criteria for a transaction, they will be split into multiple transactions. This can result in incomplete or inaccurate transactions2.
To avoid this limitation, you can use the stats command instead of the transaction command. The stats command can also group events by common values, but it does not have a limit on the number of events per group. The stats command also performs faster and consumes less memory than the transaction command1.
In your search, you are using the stats list() function to group events by src_ip and dest_ip. This function returns a multivalue field that contains all the values of a given field for each group. However, this function does not create a single correlated event like the transaction command does. Instead, it creates a table of results with one row per group and one column per field3.
Therefore, your search will produce multiple transactions instead of one because you are using the transaction command with a limit of 1000 events per transaction, and you are using the stats list() function that does not create a single correlated event.

質問 # 133
If there are fields in the data with values that are " " or empty but not null, which of the following would add a value?
- A. | eval notNULL = if(isnull (notNULL), "0" notNULL)
- B. | eval notNULL = if(isnull (notNULL), "0"
- C. | eval notNULL = "" | nullfill value=0 notNULL
- D. | eval notNULL = "" fillnull value=0 notNULL
正解：D
解説：
Explanation
The correct answer is D. | eval notNULL = "" fillnull value=0 notNULL
Option A is incorrect because it is missing a comma between the "0" and the notNULL in the if function. The correct syntax for the if function is if (condition, true_value, false_value).
Option B is incorrect because it is missing the false_value argument in the if function. The correct syntax for the if function is if (condition, true_value, false_value).
Option C is incorrect because it uses the nullfill command, which only replaces null values, not empty strings. The nullfill command is equivalent to fillnull value=null.
Option D is correct because it uses the eval command to assign an empty string to the notNULL field, and then uses the fillnull command to replace the empty string with a zero. The fillnull command can replace any value with a specified replacement, not just null values.
