Question 90
A reliability engineer combines indexed host filtering with computed error-rate filtering. In this extended practice exercise, which THREE statements about the required Splunk behavior are correct? Choose THREE.
- Use where with match() or another eval function for expression-based matching
- Use search to evaluate arbitrary arithmetic across two fields as though it were eval syntax
- Use an ordinary search field=value term for a straightforward field-value match
- Check whether missing fields make a planned where condition exclude records
- Use eval as a filter without assigning a field or a supported predicate
- Claim a failed where expression is proof the raw event was deleted from the index
Explanation
Correct Answers
A:Where accepts evaluation expressions.
C:Search provides field matching in the search language.
D:Null results may not satisfy a Boolean expression.
Incorrect Answers
B:Use where for complex comparisons requiring eval expressions.
E:Eval computes an expression into a field.
F:Search filtering does not delete indexed events.
Question 91
A compliance report needs a display placeholder for missing department values. Which Splunk approach is technically appropriate for this need?
- Apply fillnull value="Unassigned" to the intended field list
- Use rename to replace every null value without specifying a new name
- Assume fillnull creates a search-time index for the missing field
- Replace all numeric nulls with the string Unassigned and claim numeric stats remain unchanged
Explanation
Correct Answer
A:Fillnull substitutes configured values for nulls in result fields.
Incorrect Answers
B:Rename changes field names, not missing values.
C:Null substitution is not index construction.
D:Type changes can alter numeric calculations.
Question 92
A compliance report needs a display placeholder for missing department values. Which implementation detail accurately describes the required behavior?
- Replace all numeric nulls with the string Unassigned and claim numeric stats remain unchanged
- Assume fillnull creates a search-time index for the missing field
- Limit fillnull to chosen fields so unrelated nulls retain their meaning
- Treat a populated field value of 0 as a null that fillnull must overwrite
Explanation
Correct Answer
C:A field list constrains the replacement scope.
Incorrect Answers
A:Type changes can alter numeric calculations.
B:Null substitution is not index construction.
D:Zero and null are not equivalent.
Question 93
A compliance report needs a display placeholder for missing department values. Which validation or design decision would make the result reliable?
- Assume fillnull creates a search-time index for the missing field
- Use rename to replace every null value without specifying a new name
- Treat a populated field value of 0 as a null that fillnull must overwrite
- Distinguish true zero values from null before selecting a replacement token
Explanation
Correct Answer
D:A legitimate zero should not be interpreted as missing.
Incorrect Answers
A:Null substitution is not index construction.
B:Rename changes field names, not missing values.
C:Zero and null are not equivalent.
Question 94
A compliance report needs a display placeholder for missing department values. Which explanation best preserves the intended data meaning or control?
- Inspect events where the field never appears before claiming complete coverage
- Use rename to replace every null value without specifying a new name
- Replace all numeric nulls with the string Unassigned and claim numeric stats remain unchanged
- Treat a populated field value of 0 as a null that fillnull must overwrite
Explanation
Correct Answer
A:Field existence and null behavior can affect the command's result.
Incorrect Answers
B:Rename changes field names, not missing values.
C:Type changes can alter numeric calculations.
D:Zero and null are not equivalent.
Question 95
A compliance report needs a display placeholder for missing department values. In this extended practice exercise, which TWO statements about the required Splunk behavior are correct? Choose TWO.
- Replace all numeric nulls with the string Unassigned and claim numeric stats remain unchanged
- Treat a populated field value of 0 as a null that fillnull must overwrite
- Distinguish true zero values from null before selecting a replacement token
- Apply fillnull value="Unassigned" to the intended field list
- Assume fillnull creates a search-time index for the missing field
Explanation
Correct Answers
C:A legitimate zero should not be interpreted as missing.
D:Fillnull substitutes configured values for nulls in result fields.
Incorrect Answers
A:Type changes can alter numeric calculations.
B:Zero and null are not equivalent.
E:Null substitution is not index construction.
Question 96
An observability report has some null owner fields that should show Unassigned. Which Splunk approach is technically appropriate for this need?
- Apply fillnull value="Unassigned" to the intended field list, and limit fillnull to chosen fields so unrelated nulls retain their meaning
- Limit fillnull to chosen fields so unrelated nulls retain their meaning, but assume fillnull creates a search-time index for the missing field
- Apply fillnull value="Unassigned" to the intended field list, but replace all numeric nulls with the string Unassigned and claim numeric stats remain unchanged
- Distinguish true zero values from null before selecting a replacement token, but treat a populated field value of 0 as a null that fillnull must overwrite
Explanation
Correct Answer
A:The two controls work together: Fillnull substitutes configured values for nulls in result fields. A field list constrains the replacement scope.
Incorrect Answers
B:The first clause can be sound, but the second is not: Null substitution is not index construction.
C:The first clause can be sound, but the second is not: Type changes can alter numeric calculations.
D:The first clause can be sound, but the second is not: Zero and null are not equivalent.
