Which command removes results with duplicate field values?

  1. Dedup

  2. Limit

  3. Join

  4. Distinct

The correct answer is: Dedup

The command designed to remove results with duplicate field values is the dedup command. When you use dedup in Splunk, it effectively filters out any duplicate values for a specified field, ensuring that only the first occurrence of each unique value is retained in your results. This is particularly useful when you want to simplify your data set by eliminating redundancy, making it easier to analyze or visualize. For instance, if you are analyzing log entries with the same user ID, dedup can help you focus on each user’s first entry instead of seeing repetitive data. In contrast, other options do not serve this function: limit is used to restrict the number of results returned in a search, join merges two data sets based on a common field but does not eliminate duplicates, and distinct, while commonly used in data handling, is not a command in Splunk's search language. Thus, dedup rightly stands out as the correct choice for removing duplicate field values.
