20+ practice questions focused on Performance Tuning — one of the most tested topics on the Splunk Enterprise Certified Architect (SPLK-2002) (SPLK-2002) exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Performance Tuning PracticeA Splunk administrator needs to identify why a specific search is experiencing high 'Disk Read' wait times. Which tool or log source should be utilized to correlate search IDs with specific disk latency metrics?
Explanation: The Monitoring Console aggregates indexer metrics, including disk latency, and can correlate those with search activity. Audit logs record search IDs and user actions, so combining audit logs with indexer metrics via the Monitoring Console allows an administrator to link a specific search ID to disk read wait times. The other tools either lack the necessary correlation or do not provide disk latency metrics.
You are tuning a Splunk heavy forwarder. The 'parsingQueue' is consistently full. Which configuration change in props.conf or inputs.conf is recommended?
Explanation: The parsing queue is typically blocked by complex regex transformations or heavy parsing loads. Adjusting pipeline settings or splitting the workload across more CPUs is necessary.
Which setting in indexes.conf should be tuned to balance memory usage and indexing speed for a high-volume indexer?
Explanation: maxDataSize controls the target size of hot buckets before Splunk rolls them to warm; tuning it directly balances how much memory the indexer dedicates to active buckets versus how frequently it performs bucket rolling and disk I/O. Larger values keep more data in memory (faster search/indexing) but consume more RAM, while smaller values reduce memory pressure at the cost of more frequent rolling. This is the primary knob in indexes.conf for that trade-off.
An administrator notices that searches are slow due to high CPU utilization on indexers. Which configuration change in limits.conf directly controls the maximum number of concurrent searches allowed on an indexer?
Explanation: max_searches_per_cpu in limits.conf sets the multiplier applied to the number of CPU cores to determine the maximum concurrent searches an indexer will run. Splunk computes the cap as max_searches_per_cpu × number of cores, so lowering this value directly throttles concurrent search load and reduces CPU contention. This is the documented knob for controlling search concurrency per indexer.
When using Data Model acceleration, which setting should be monitored to ensure the background summary search does not starve other searches of resources?
Explanation: The 'tstats_max_search_time' or similar limits in limits.conf manage how long these accelerated searches run, but the 'accelerated_search_max_threads' setting controls the concurrency.

Practice all Performance Tuning questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of Performance Tuning. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Performance Tuning questions on the SPLK-2002 frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Performance Tuning is tested as part of the Splunk Enterprise Certified Architect (SPLK-2002) (SPLK-2002) blueprint. Practicing with targeted Performance Tuning questions ensures you can handle any format or difficulty that appears.
