The answer is that fields extracted automatically are available for searching immediately. This is correct because Splunk’s automatic field extraction, often called auto kv or key-value extraction, parses structured data formats like JSON and XML during indexing, identifying key-value pairs and making them searchable without any manual configuration. On the SPLK-1002 exam, this concept tests your understanding of how Splunk handles structured versus unstructured data—a common trap is assuming all fields require manual extraction or that auto extraction only works on raw text. Remember, Splunk’s auto kv is format-aware: if your data is JSON or XML, the fields are ready to search the moment the data is indexed. A useful memory tip is “JSON and XML auto kv—fields are free and immediate.”
SPLK-1002 Using Fields and Lookups Practice Question
This SPLK-1002 practice question tests your understanding of using fields and lookups. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which THREE of the following are true about automatic field extraction in Splunk?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It can extract fields from structured data like JSON and XML.
Option A is correct because Splunk's automatic field extraction (also known as 'auto kv' or 'key-value extraction') can parse structured data formats such as JSON and XML. When Splunk indexes data, it automatically identifies key-value pairs in these formats and extracts them as searchable fields without requiring manual configuration.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Auto extraction cannot be disabled for specific sourcetypes.
Why it's wrong here
It can be disabled via props.conf.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Splunk often tests the misconception that automatic field extraction is mutually exclusive with custom extractions, but in reality they can be used together, and auto extraction can be selectively disabled per sourcetype.
Detailed technical explanation
How to think about this question
Under the hood, Splunk's automatic field extraction uses the `kv` search command and the `AUTO_KV` setting in props.conf. For JSON and XML, Splunk uses a built-in parser that recursively extracts nested keys. A subtle behavior is that auto extraction may not capture fields from malformed or deeply nested structures, requiring custom extractions or the `spath` command for reliable parsing. In real-world scenarios, disabling auto extraction for high-volume sourcetypes can improve indexing performance.

→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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
