Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
KV Store lookup updated via REST API
KV Store lookups can be updated via REST API calls without reindexing and provide fast search-time lookups. Option A is incorrect because file lookups require rewriting the file and reloading. Option B is incorrect because index-time lookups require reindexing. Option C is incorrect because scripted lookups call the API on every search, causing severe performance issues.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
CSV file lookup updated by a scheduled script
Why it's wrong here
Frequent file updates cause concurrency issues and delays as Splunk reloads the file.
- ✗
Index-time lookup using a transformation that queries the API during indexing
Why it's wrong here
Index-time lookups are static after indexing; updating them requires reindexing.
- ✗
Scripted lookup that calls the API on each search
Why it's wrong here
Calling an API on every search is very slow and impractical for high-frequency updates.
- ✓
KV Store lookup updated via REST API
Why this is correct
KV Store supports rapid updates and efficient indexed lookups at search time.
