Which is the most efficient use of a wildcard character in Splunk?
- A.
Fail*
- B.
*ail
- C.
Fa*l
- D.
F**l
Correct Answer
A. Fail*Explanation
The most efficient use of a wildcard character in Splunk is "fail*". This wildcard allows for matching any term that starts with "fail", which can be useful for searching for multiple variations of a specific term. The other options, "*ail", "fa*l", and "f**l", are less efficient because they either match any term that ends with "ail", any term that has "fa" followed by any character and then "l", or any term that starts with "f" and ends with "l", respectively.Rate this question:

Which of these terms take precedence in this search: (status=fail action=login) OR ((status=failed action=edit) AND ((role=power AND username=*) OR rfid=*))
- A.
Role=power
- B.
Action=login
- C.
Rfid=*
- D.
Status=failed
Correct Answer
A. Role=powerExplanation
In this search query, the term "role=power" takes precedence because it is part of the innermost parentheses. The innermost parentheses are evaluated first, so the conditions within them have higher precedence. Therefore, the condition "role=power" is prioritized over the other conditions in the search query.Rate this question:

Regular expressions in Splunk are NOT case sensitive.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Regular expressions in Splunk are case sensitive. This means that when using regular expressions in Splunk, the pattern matching is sensitive to the case of the characters. For example, if a regular expression is used to search for the word "splunk" in a log file, it will only match instances of "splunk" with the same capitalization. If the word "Splunk" or "SPLUNK" is present in the log file, it will not be considered a match. Therefore, the correct answer is False.Rate this question:

The tonumber function can convert a binary value to a decimal by adding the optional base argument of "2" to the function.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The tonumber function in Lua can convert a binary value to a decimal by adding the optional base argument of "2" to the function. This means that if we pass a binary value as a string to the tonumber function and specify the base as 2, it will convert the binary value to its decimal equivalent. Therefore, the statement "The tonumber function can convert a binary value to a decimal by adding the optional base argument of "2" to the function" is true.Rate this question:

Given a field-value pair of action=addtocart, and a search string of ...| eval SaleMade=if(action=purchase, "Sale", "No Sale"), the value of SaleMade is ______________.
- A.
Sale Made
- B.
No Sale
- C.
Sale
- D.
Purchase Made
Correct Answer
B. No SaleExplanation
The given field-value pair is "action=addtocart" and the search string is "...| eval SaleMade=if(action=purchase, "Sale", "No Sale")". This search string uses the eval command to create a new field called SaleMade. It checks if the value of the action field is "purchase". If it is, then the value of SaleMade is "Sale". If the value of the action field is not "purchase", then the value of SaleMade is "No Sale". Since the given field-value pair is "action=addtocart" and not "action=purchase", the value of SaleMade is "No Sale".Rate this question:

Max(7, 101, 53, "Four", 26, "Eight") would return a maximum value of ___________. Select your answer.
- A.
Eight
- B.
7
- C.
101
- D.
