Objective 4.1
Enterprise Certified ArchitectList sizing considerations
Objective 4.1 sits in Infrastructure Planning: Resource Planning, which carries 7% of the Enterprise Certified Architect exam. The questions below are original, written from the official objective title above, and each explanation cites the Splunk page it rests on.

A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
An indexer with 24 idle cores is not keeping up with ingest, so you turn on index parallelization. What does that feature let the indexer maintain?
Correct.
Checked against help.splunk.com, August 2026Concept
A second pipeline set uses cores and disk that would otherwise sit idle. It is a way to spend spare capacity rather than to add machines.
Why D
Splunk states that index parallelization is a feature that allows an indexer to maintain multiple pipeline sets, and that a pipeline set handles the processing of data from ingestion through event processing to writing events to disk.

Splunk Docs: Manage pipeline sets for index parallelization, checked August 2026Index parallelization is a feature that allows an indexer to maintain multiple pipeline sets. A pipeline set handles the processing of data from ingestion of raw data, through event processing, to writing the events to disk.
Now you: objective 4.1 questions
No account needed. The explanation opens when you answer.
Sample question 1 of 3
You have not changed any indexing settings on a freshly installed indexer. How many pipeline sets does it run?
Sample question 2 of 3
Your indexer has spare cores and spare I/O, so you configure it to run two pipeline sets. What does that do to its indexing throughput capacity?
Sample question 3 of 3
You enable two pipeline sets on an indexer, but one feed sees no throughput gain at all. Which data cannot use index parallelization?
