Splunk SPLK-5002 Exam - Topic 5 Question 10 Discussion

Actual exam question for Splunk's SPLK-5002 exam
Question #: 10
Topic #: 5
[All SPLK-5002 Questions]

Which Splunk configuration ensures events are parsed and indexed only once for optimal storage?

Show Suggested Answer Hide Answer
Suggested Answer: C

Why Use Index-Time Transformations for One-Time Parsing & Indexing?

Splunk parses and indexes data once during ingestion to ensure efficient storage and search performance. Index-time transformations ensure that logs are:

Parsed, transformed, and stored efficiently before indexing. Normalized before indexing, so the SOC team doesn't need to clean up fields later. Processed once, ensuring optimal storage utilization.

Example of Index-Time Transformation in Splunk: Scenario: The SOC team needs to mask sensitive data in security logs before storing them in Splunk. Solution: Use an INDEXED_EXTRACTIONS rule to:

Redact confidential fields (e.g., obfuscate Social Security Numbers in logs).

Rename fields for consistency before indexing.

Universal forwarders are great for data collection, but I don't think they relate to how events are indexed or parsed only once.

I practiced a similar question where the focus was on optimizing storage, and I think search head clustering was more about distributing searches rather than indexing.

I remember something about index time transformations being important for how data is stored, but I can't recall if they specifically prevent multiple indexing.

I think summary indexing might be the right answer since it helps reduce storage by summarizing data, but I'm not entirely sure.

I'm feeling pretty confident about this one. Index time transformations are the Splunk feature that ensures events are parsed and indexed only once, which is the most efficient approach for storage. I'm going with C.

Okay, let me think this through step-by-step. Summary indexing is about summarizing data, not ensuring single indexing. Universal forwarder is for forwarding data, not indexing. Search head clustering is for high availability, not single indexing. I think C is the right answer here.

Hmm, I'm a bit confused on this one. I know Splunk has a lot of different configuration options, but I'm not sure which one specifically handles event parsing and indexing. I'll have to think this through carefully.

I don't know, guys. This question seems a bit 'Splunky' to me. Maybe the answer is just to have a good sense of humor and a backup plan. Just sayin'.
