- A
Increase the bucket size in the acceleration settings to reduce the number of buckets being rebuilt.
Why wrong: Incorrect: Increasing bucket size would increase summary size and rebuild time, not decrease.
- B
Create a custom data model that includes only the fields needed for security investigations and enable acceleration.
Why wrong: Incorrect: This does not directly reduce summary size or rebuild time; it may still be large.
- C
Reduce the acceleration time range from 'All time' to 'Last 7 days' to limit the summary size and rebuild duration.
Correct: Limiting the acceleration range reduces both storage and rebuild time, still covering recent data.
- D
Disable acceleration and instead rely on the security team to use more focused time ranges.
Why wrong: Incorrect: This removes the acceleration benefit and does not solve the underlying performance issue.
SPLK-1002 Data Models and Best Practices Practice Question
This SPLK-1002 practice question tests your understanding of data models and best practices. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
You are a Splunk administrator for a large e-commerce company. The security team frequently runs searches against the web access logs (sourcetype=access_combined) to investigate suspicious activity. These searches often take 5-10 minutes to complete, and the team is frustrated. You decide to implement a data model to accelerate these searches. After creating a data model based on the CIM Web model and enabling acceleration for the 'Web' dataset, you notice that the acceleration summary size grows to over 50 GB and the rebuild process takes more than an hour every night, causing some searches to time out during the rebuild window. What is the most effective way to address this issue?
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 acceleration time range from 'All time' to 'Last 7 days' to limit the summary size and rebuild duration.
Option C is correct because reducing the acceleration time range from 'All time' to a shorter window like 'Last 7 days' directly limits the amount of data the acceleration summary must cover. This shrinks the summary size (under 50 GB) and shortens the nightly rebuild time, preventing search timeouts during the rebuild window while still accelerating the most relevant recent data for security investigations.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often think customizing fields (Option B) is the best fix, but they overlook that the time range is the primary driver of summary size and rebuild time in high-volume environments.
Detailed technical explanation
How to think about this question
Data model acceleration in Splunk works by pre-computing a summary of indexed data into a TSIDX (time-series index) file, which is rebuilt nightly based on the acceleration time range. The rebuild process scans all raw data within that range, so a range of 'All time' can cause massive summary sizes (e.g., 50+ GB) and long rebuild durations, especially with high-volume sourcetypes like access_combined. Limiting the time range to 'Last 7 days' reduces the data scanned during rebuild, making it faster and less resource-intensive, while still accelerating the most frequently queried recent data for security investigations.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the SPLK-1002 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
