The search "fail" "password" returns the same results as ______________.
- A.
Fail AND password
- B.
Fail OR password
- C.
Fail=password
- D.
Fail NOT password
Correct Answer

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:

Which is a valid Splunk comparison operator?
- A.
!=
- B.

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:

A Boolean operator that can be used within an eval command, but can't be used as a Splunk search term is ______________.
- A.
XOR
- B.
NOT
- C.
AND
- D.
OR
Correct Answer
A. XORExplanation
XOR is the correct answer because it is a Boolean operator that can be used within an eval command in Splunk. However, XOR cannot be used as a Splunk search term. XOR (exclusive OR) is used to compare two values and returns true if only one of the values is true.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:

- D.
To aid Splunk in parsing which part of a subsearch to pass to search heads
Correct Answer
C. To return only a part of string field valuesExplanation
The purpose of the substr function is to return only a part of string field values. This means that it allows users to extract a specific portion of a string, such as a substring, based on specified starting and ending positions. This can be useful in various scenarios, such as extracting a specific section of a longer text or manipulating and formatting strings in a desired way.Rate this question:

The eval command substr("Dream Crusher", -7, 5) will result in a string of _____________.
- A.
Crush
- B.
Am Crusher
- C.
Dream C
- D.
Rusher
Correct Answer
A. CrushExplanation
The eval command substr("Dream Crusher", -7, 5) will result in a string of "Crush". The substr() function is used to extract a portion of a string, starting from a specified position and with a specified length. In this case, it starts from the 7th character from the end of the string "Dream Crusher" and extracts a substring of length 5, resulting in "Crush".Rate this question:

Given a field-value pair of Department="Sales", ...| eval Department=upper(Department), will result in a new field-value pair of Department="SALES".
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The given field-value pair of Department="Sales" is being passed through the eval command with the upper() function. The upper() function converts the value of the Department field to uppercase. Therefore, the result will be a new field-value pair of Department="SALES".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.
