NEW QUESTION # 125
A calculated field is a shortcut for performing repetitive, long, or complex transformations using which of the following commands?
- A. eval
- B. transaction
- C. stats
- D. lookup
Answer: A
Explanation:
The correct answer is D. eval.
A calculated field is a field that is added to events at search time by using an eval expression. A calculated field can use the values of two or more fields that are already present in the events to perform calculations. A calculated field can be defined with Splunk Web or in the props.conf file. They can be used in searches, reports, dashboards, and data models like any other extracted field1.
A calculated field is a shortcut for performing repetitive, long, or complex transformations using the eval command. The eval command is used to create or modify fields by using expressions. The eval command can perform mathematical, string, date and time, comparison, logical, and other operations on fields or values2.
For example, if you want to create a new field named total that is the sum of two fields named price and tax, you can use the eval command as follows:
| eval total=price+tax
However, if you want to use this new field in multiple searches, reports, or dashboards, you can create a calculated field instead of writing the eval command every time. To create a calculated field with Splunk Web, you need to go to Settings > Fields > Calculated Fields and enter the name of the new field (total), the name of the sourcetype (sales), and the eval expression (price+tax). This will create a calculated field named total that will be added to all events with the sourcetype sales at search time. You can then use the total field like any other extracted field without writing the eval expression1.
The other options are not correct because they are not related to calculated fields. These options are:
A) transaction: This 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 contiguous3.
B) lookup: This command is used to enrich events with additional fields from an external source, such as a CSV file or a database. A lookup can add fields to events based on the values of existing fields, such as host, source, sourcetype, or any other extracted field.
C) stats: This command is used to calculate summary statistics on the fields in the search results, such as count, sum, average, etc. It can be used to group and aggregate data by one or more fields.

NEW QUESTION # 126
Which of the following statements about event types is true? (select all that apply)
- A. Event types categorize events based on a search.
- B. Event types can be a useful method for capturing and sharing knowledge.
- C. Event types can be tagged.
- D. Event types must include a time range,
Answer: A,B,C
Explanation:
Reference:
As mentioned before, an event type is a way to categorize events based on a search string that matches the events2. Event types can be tagged, which means that you can apply descriptive labels to event types and use them in your searches2. Therefore, option A is correct. Event types categorize events based on a search string, which means that you can define an event type by specifying a search string that matches the events you want to include in the event type2. Therefore, option C is correct. Event types can be a useful method for capturing and sharing knowledge, which means that you can use event types to organize your data into meaningful categories and share them with other users in your organization2. Therefore, option D is correct. Event types do not have to include a time range, which means that you can create an event type without specifying a time range for the events2. Therefore, option B is incorrect.
NEW QUESTION # 127
Which of the following eval commands will provide a new value for host from src if it exists?
- A. | eval host = if (NOT src = host, src, host)
- B. | eval host = if (isnotnull (src), src, host)
- C. | eval host = if (src = host, src, host)
- D. | eval host = if (isnu11 (src), src, host)
Answer: B
Explanation:
The eval command is a Splunk command that allows you to create or modify fields using expressions .
The if function is an expression that evaluates a condition and returns a value based on whether the condition is true or false. The syntax of the if function is if(X,Y,Z), where X is the condition, Y is the value to return if X is true, and Z is the value to return if X is false.
The isnotnull function is an expression that returns true if the argument is not null, and false otherwise. The syntax of the isnotnull function is isnotnull(X), where X is the argument to check.
Therefore, the expression if (isnotnull (src), src, host) returns the value of src if it is not null, and the value of host otherwise. This means that it will provide a new value for host from src if it exists, and keep the original value of host otherwise.
NEW QUESTION # 128
After manually editing; a regular expression (regex), which of the following statements is true?
- A. It is no longer possible to edit the field extraction in the Field Extractor (FX) UI.
- B. The Field Extractor (FX) UI keeps its own version of the field extraction in addition to the one that was manually edited.
- C. Changes made manually can be reverted in the Field Extractor (FX) UI.
- D. It is not possible to manually edit a regular expression (regex) that was created using the Field Extractor (FX) UI.
Answer: A
Explanation:
After manually editing a regular expression (regex) that was created using the Field Extractor (FX) UI, it is no longer possible to edit the field extraction in the FX UI. The FX UI is a tool that helps you extract fields from your data using delimiters or regular expressions. The FX UI can generate a regex for you based on your selection of sample values or you can enter your own regex in the FX UI. However, if you edit the regex manually in the props.conf file, the FX UI will not be able to recognize the changes and will not let you edit the field extraction in the FX UI anymore. You will have to use the props.conf file to make any further changes to the field extraction. Changes made manually cannot be reverted in the FX UI, as the FX UI does not keep track of the changes made in the props.conf file. It is possible to manually edit a regex that was created using the FX UI, as long as you do it in the props.conf file.
Therefore, only statement B is true about manually editing a regex.
NEW QUESTION # 129
The timechart command is an example of which of the following command types?
- A. Orchestrating
- B. Generating
- C. Transforming
- D. Statistical
Answer: C
Explanation:
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.

NEW QUESTION # 133
What type of command is eval?
- A. Report generating
- B. Distributable streaming
- C. Centralized streaming
- D. Streaming in some modes
Answer: B
Explanation:
Explanation
The correct answer is C. Distributable streaming. This is because the eval command is a type of command that can run on the indexers before the results are sent to the search head. This reduces the amount of data that needs to be transferred and improves the search performance. Distributable streaming commands can operate on each event or result individually, without depending on other events or results. You can learn more about the types of commands and how they affect search performance from the Splunk documentation1.
NEW QUESTION # 134
Which of the following actions can the eval command perform?
- A. Create or replace an existing field.
- B. Remove fields from results.
- C. Save SPL commands to be reused in other searches.
- D. Group transactions by one or more fields.
Answer: A
Explanation:
Explanation
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.
NEW QUESTION # 135
What is the correct syntax to search for a tag associated with a value on a specific fields?
- A. Tag<filed(tagname.)
- B. Tag::<filed>=<tagname>
- C. Tag-<field?
- D. Tag=<filed>::<tagname>
Answer: B
Explanation:
Reference:
https://docs.splunk.com/Documentation/Splunk/8.0.3/Knowledge/TagandaliasfieldvaluesinSplunkWeb A tag is a descriptive label that you can apply to one or more fields or field values in your events2. You can use tags to simplify your searches by replacing long or complex field names or values with short and simple tags2. To search for a tag associated with a value on a specific field, you can use the following syntax: tag::<field>=<tagname>2. For example, tag::status=error will search for events where the status field has a tag named error. Therefore, option D is correct, while options A, B and C are incorrect because they do not follow the correct syntax for searching tags.

- A. Pipes
- B. Colons
- C. Spaces
- D. Tabs
Answer: A,C,D
Explanation:

https://community.splunk.com/t5/Splunk-Search/Field-Extraction-Separate-on-Colon/m-p/29751 The Field Extractor (FX) is a tool that helps you extract fields from your data using delimiters or regular expressions. Delimiters are characters or strings that separate fields in your data. Some of the delimiters that will work with FX are:
Tabs: horizontal spaces that align text in columns.
Pipes: vertical bars that often indicate logical OR operations.
Spaces: blank characters that separate words or symbols.
Therefore, the delimiters A, B, and D will work with FX.
NEW QUESTION # 140
What does the transaction command do?
- A. Returns the number of credit card transactions found in the event logs.
- B. Separates two events based on one or more values.
- C. Creates a single event from a group of events.
- D. Groups a set of transactions based on time.
Answer: C
Explanation:
The transaction command is a search command that creates a single event from a group of events that share some common characteristics. The transaction command can group events based on fields, time, or both. The transaction command can also create some additional fields for each transaction, such as duration, eventcount, startime, etc. The transaction command does not group a set of transactions based on time, but rather groups a set of events into a transaction based on time. The transaction command does not separate two events based on one or more values, but rather joins multiple events based on one or more values. The transaction command does not return the number of credit card transactions found in the event logs, but rather creates transactions from the events that match the search criteria.
NEW QUESTION # 141
When creating a Search workflow action, which field is required?
- A. Search string
- B. Data model name
- C. Permission setting
- D. An eval statement
Answer: A
Explanation:
Reference: https://docs.splunk.com/Documentation/Splunk/8.0.3/Knowledge/Setupasearchworkflowaction A workflow action is a link that appears when you click an event field value in your search results2. A workflow action can open a web page or run another search based on the field value2. There are two types of workflow actions: GET and POST2. A GET workflow action appends the field value to the end of a URI and opens it in a web browser2. A POST workflow action sends the field value as part of an HTTP request to a web server2. When creating a Search workflow action, which is a type of GET workflow action that runs another search based on the field value, the only required field is the search string2. The search string defines the search that will be run when the workflow action is clicked2. Therefore, option A is correct, while options B, C and D are incorrect because they are not required fields for creating a Search workflow action.
