Discuss Splunk SPLK-1001 Exam Topic 7 Question 87

What is the result of the following search?

index=myindex source=c: \mydata. txt NOT error=*

AOnly data where the error field is present and does not contain a value will be displayed.

BOnly data with a value in the field error will be displayed.

COnly data that does not contain the error field will be displayed.

DOnly data where the value of the field error does not equal an asterisk (*) will be displayed.

Suggested Answer: C

The search query index=myindex source=c: mydata. txt NOT error=* specifies three criteria for the events to be returned:

The index must be myindex, which is a user-defined index that contains the data from a specific source or sources.

The source must be c: mydata. txt, which is the name of the file or directory where the data came from.

The error field must not exist in the events, which is indicated by the NOT operator and the wildcard character (*).

The NOT operator negates the following expression, which means that it returns the events that do not match the expression. The wildcard character () matches any value, including an empty value or a null value. Therefore, the expression NOT error=means that the events must not have an error field at all, regardless of its value.

The search query does not use quotation marks around the source value, which means that it is case-sensitive and exact. If there are any variations in the source name, such as capitalization or spacing, they will not match the query.

D seems off to me, an asterisk is just a wildcard, right?

Julieta 11 months ago

I’m leaning towards A, but not sure.

Reuben 11 months ago

Wait, so does that mean errors are completely ignored?

Merilyn 11 months ago

Totally agree with C! Makes sense.

Scot 11 months ago

I think it's C, no error field means no errors.

Tequila 12 months ago

I feel like I might have seen something about how NOT works with fields, but I can't recall if it was about excluding fields entirely or just their values.

Cheryl 12 months ago

I'm a bit confused about the NOT operator here. Does it really mean that only entries without the error field will show up?

Lindsey 12 months ago

I remember practicing a question similar to this, and I think it was about filtering out specific fields. Could it be option C?

Shonda 1 year ago

I think the search is excluding any entries that have the error field, but I'm not sure if it means only those without the field at all.

I'm pretty confident that the answer is D. The NOT error=* part means it will show data where the error field doesn't equal an asterisk, so it's excluding any data where the error field is either empty or contains an asterisk.

Ezekiel 1 year ago

Okay, I think I've got it. The query is looking for data from the c:\mydata.txt file in the myindex index, and it's excluding any data where the error field contains a value. So the answer is C - it will only display data that doesn't have the error field.

Hmm, the NOT error=* part is confusing me. I'm not sure if that means it will only show data where the error field is present but doesn't contain an asterisk, or if it will show data where the error field is not present at all. I'll have to re-read the question a few times.

This looks like a Splunk query, so I'll need to think through the logic carefully. The NOT operator is throwing me off a bit, but I think I can figure this out.

Carmen 1 year ago

This question seems to be asking about some kind of metric or calculation that considers different data sources. I'll need to think carefully about what information is being combined and how that might be calculated as an average.

I agree with user3. The NOT part excludes any data with the error field.

Brandon 2 years ago

No, B isn't right. If it has NOT error=*, it shouldn’t include fields with any value in error.

Albert 2 years ago

Could be B, though. It might mean only data with an error field gets shown.

Vonda 2 years ago

I think it's C. It says NOT error=* so it should exclude records with the error field.

Lauryn 2 years ago

Yeah, I'm a bit confused. What do you think the answer is?

Brandon 2 years ago

This question on search results seems tricky.
