Splunk Enterprise Certified Admin Practice Test

What is a disadvantage of indexed field extractions?

1. Improves indexing performance

2. Reduces the number of redundant fields

3. Puts less strain on storage resources

4. Increased storage size compared to original data

The correct answer is: Increased storage size compared to original data

The correct answer highlights a key aspect of indexed field extractions, which is that they can lead to an increased storage size when compared to the original data. Indexed field extractions involve the process of storing specific fields directly in the index at the time of data ingestion. While this allows for faster searching and retrieval of those fields later, it also means that additional space is required to store these extracted fields alongside the original data. When indexed fields are created, the system essentially maintains more copies of data, as both the raw events and the indexed fields coexist. This can lead to an increase in overall storage requirements, which is an important consideration for managing and optimizing data storage in Splunk. Understanding this trade-off is crucial for Splunk administrators when designing systems, as it impacts resource allocation and cost efficiency.
