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.
A Splunk administrator notices that a data model acceleration summary is not updating as expected. The data model is accelerated with a summary range of 30 days. What is the most likely cause of this issue?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The summary index is not writable due to insufficient disk space.
Option B is correct because data model acceleration relies on a summary index to store pre-computed results. If the disk hosting that summary index is full, the acceleration process cannot write new data, causing the summary to stop updating. Splunk will log errors related to disk space, and the acceleration status will show as stalled or incomplete.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
The data model is based on a time range older than the summary range.
Why it's wrong here
The summary range covers the data; old data is not a problem.
✓
The summary index is not writable due to insufficient disk space.
Why this is correct
Insufficient disk space prevents summary updates, stopping acceleration.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
The data model includes calculated fields that are not search-time extractable.
Why it's wrong here
Calculated fields are acceptable; acceleration works on search-time fields.
✗
The data model acceleration is configured to run only on real-time searches.
Why it's wrong here
Acceleration runs on scheduled summaries, not on real-time searches.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume the issue is with the data model definition or time range, rather than recognizing that summary index disk space is a common operational cause for acceleration failures.
Detailed technical explanation
How to think about this question
Under the hood, Splunk uses the `summarize` command to populate the summary index, which is stored in the `_summary` index by default. When disk space is exhausted, the indexer cannot write new buckets, and the acceleration job fails silently or with a 'No space left on device' error. In a distributed environment, this can also occur if the summary index is on a volume with insufficient capacity, even if other indexes have space.
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.
