Splunk Enterprise Certified Admin Practice Test

What is the purpose of the Last Chance Index?

1. To store all incoming events.

2. To catch and index events destined for non-existent indexes.

3. To limit data retention.

4. To optimize search performance.

The correct answer is: To catch and index events destined for non-existent indexes.

The Last Chance Index serves a specific and crucial role in managing data that is intended for indexing in Splunk. Its primary purpose is to catch and index events that are destined for non-existent indexes. When data is being sent to Splunk, if the specified target index does not exist or is misconfigured, those events would typically be lost. However, by using the Last Chance Index, Splunk can capture these events, preventing loss of valuable data and allowing for subsequent analysis. This functionality is critical for maintaining data integrity and ensuring that important logs and events are not discarded due to mishaps in index configuration. It acts as a safeguard, ensuring that all ingested data is accounted for, even if the intended indexing path is flawed. Using this index simplifies debugging and provides a way to handle misrouted data during the ingestion process effectively.
