What is the accurate statement about tsidx files in Splunk?
Short answer
C A tsidx file consists of a lexicon and a posting list.
Question
Key Takeaways
The exam tests the internal structure and lifecycle of tsidx files; the common trap is confusing update/cleanup intervals or assuming a bucket always contains exactly one tsidx file.
The TSIDX file is Splunk's index file containing a lexicon and posting list. Community consensus agrees option C is correct; the file is updated every 5 minutes and outdated data cleaned every 30 minutes, and a bucket may contain more than one tsidx file when accelerated.
Common mistake: Choosing D, assuming each bucket contains only one tsidx file, is the common mistake; in reality, data model acceleration can create additional tsidx files in a bucket.
Expert Analysis
Why the Answer Is Correct
A tsidx file is the actual index used by Splunk, structured like a book index with a lexicon (the unique terms) and a posting list (the locations where terms appear). This matches option C exactly. Community comments confirm this definition and note that the tsidx file is updated every 5 minutes, not 30.
Why the Other Options Are Wrong
Option A is wrong because tsidx files are updated every 5 minutes, not every 30 minutes; the 30-minute interval is for cleaning out outdated data. Option B reverses these intervals. Option D is wrong because while each bucket usually has one tsidx file, data model acceleration can create additional tsidx files, and buckets can contain multiple tsidx files in certain scenarios.
Community Comment Notes
Comment 2 provides the authoritative breakdown: 'The TSIDX is an index file such as a book summary. It contains a Lexicon and a Posting List.' It also clarifies the update and cleanup intervals, and explains that D is false because 'you have naturally one tsidx file, when you accelerate you…' — indicating acceleration creates more. Comment 1 is off-topic but shows real exam interest. The unanimous vote for C matches the suggested answer.

Exam Strategy
Memorize the tsidx file lifecycle: it is updated every 5 minutes and stale data is cleaned every 30 minutes. Also remember that data model acceleration can create additional tsidx files, so a bucket is not limited to one tsidx file.

emlch 👍 1The TSIDX is an index file such as a book summary. It contains a Lexicon and a Posting List. The TSIDX is updated every 5 minutes and gets clean up for outdated data every 30 minutes. What is outdated data? We can think for example in data model acceleration, we have to select a timerange which our datamodel will be accelerate. D is false, you have naturally one tsidx file, when you accelerate your DM you have two.
