Click for Answer
C. Utilize specific fields to return only the data that is required.
Answer Description Explanation : When creating performant searches in Splunk, it is a best practice to utilize
specific fields to return only the data that is required. This approach minimizes the amount
of data processed and speeds up search performance. By explicitly specifying the fields of
interest using commands likefields, you reduce the overhead on Splunk’s processing
engine, leading to faster and more efficient queries. In contrast, using wildcards or overly
broad searches can lead to slower performance due to the increased data volume being
processed.
