SPLK-1001 Splunk Basics and Interface Navigation Practice Question
A medium-sized enterprise uses Splunk Enterprise with a single indexer and one search head. They have 50 universal forwarders sending data from web servers, application servers, and database logs. Recently, the indexer crashed during peak hours. The administrator restarted the indexer and it came back up. After analyzing the crash log, they found that the indexer ran out of memory. The indexer has 16 GB RAM and the default memory settings. The daily indexing volume is about 20 GB. The administrator is concerned about stability. They want to prevent future crashes without adding hardware. What should they do?
⚠ Common exam trap
Test-takers frequently think increasing memory allocation solves performance issues, but in a constrained environment with a single indexer, reducing memory prevents OOM crashes, while increasing it would worsen the problem.
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
✓
Reduce the max memory for the indexer process in limits.conf
The indexer crashed due to running out of memory with 16 GB RAM and default settings. Reducing the max memory for the indexer process in limits.conf (specifically the maxMemMB parameter) limits the heap size used by Splunk, preventing out-of-memory (OOM) kills during peak indexing loads. This is a software-level tuning that avoids hardware upgrades by capping memory consumption to a safe level below the physical RAM.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Reduce the number of forwarders sending data
Why it's wrong here
Would reduce load but not the best first step; might lose data.
- ✗
Switch universal forwarders to heavy forwarders
Why it's wrong here
Heavy forwarders use more resources, not directly addressing indexer memory.
- ✓
Reduce the max memory for the indexer process in limits.conf
Why this is correct
This reduces memory usage and prevents crashes.
- ✗
Increase the max memory for the indexer process in limits.conf
Why it's wrong here
Would increase memory usage, worsening the crash.
