Question 257 of 510
Basic Searching and Transforming CommandsmediumMultiple ChoiceObjective-mapped

Quick Answer

The answer is 3. This is correct because the `dedup` command with a specified field removes duplicate events based on that field’s value, keeping only the first occurrence of each unique value. In this search, even though there are 15 total events, the field in question contains only 3 distinct values, so `dedup` outputs exactly those 3 unique events. On the Splunk Core Certified User SPLK-1002 exam, this tests your understanding of how `dedup` command behavior differs from simply counting events—a common trap is assuming `dedup` removes all duplicates across multiple fields or that it counts events after deduplication, but it strictly retains the first instance per unique field value. To remember this, think of `dedup` as a filter that collapses a dataset down to its distinct categories, not a count of total rows. A helpful memory tip: “Dedup drops duplicates, keeping one per unique—so the output count equals the number of unique field values, not the original event total.”

Correct answer & explanation

3

The search uses the `dedup` command with a field name, which removes duplicate events based on that field. With 15 total events but only 3 unique values in the specified field, `dedup` keeps the first occurrence of each unique value, outputting exactly 3 events.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

    Why it's wrong here

    This is before stats aggregation.

  • 3

    Why this is correct

    stats count by user produces one event per distinct user.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Splunk often tests the misconception that `dedup` counts all events or that it operates on the total event count rather than the number of unique field values, leading candidates to pick the total event count (15) instead of the correct unique count (3).

Detailed technical explanation

How to think about this question

The `dedup` command in Splunk works by comparing the specified field values across events, keeping only the first occurrence of each unique value and discarding subsequent duplicates. Under the hood, it uses a hash table to track seen values, and the order of events is determined by the search pipeline (e.g., index time or any prior sorting). In real-world scenarios, this is critical for reducing noise in log analysis, such as keeping only the first login event per user from a stream of repeated authentication attempts.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A practitioner preparing for the SPLK-1002 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
