The answer is that the data model acceleration needed to be rebuilt after the upgrade. When Splunk is upgraded, the underlying data model acceleration summaries can become stale or incompatible, causing the CIM Authentication dashboard to show a dramatically lower event count and missing fields even though the raw data is still indexed correctly. This occurs because acceleration creates pre-computed, compressed summaries that must be regenerated to align with any changes in the data model structure or the Splunk version. On the SPLK-1003 exam, this scenario tests your understanding that data model acceleration is not automatically rebuilt during an upgrade, and a common trap is to assume field definitions or permissions are at fault. Remember the memory tip: “After an upgrade, accelerate—rebuild the data model to rehydrate the summaries.”
SPLK-1003 Macros, Saved Searches and CIM Practice Question
This SPLK-1003 practice question tests your understanding of macros, saved searches and cim. 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.
After upgrading Splunk to a new version, the Security team notices that the CIM Authentication dashboard is showing a much lower number of events than before. They verify that the data is still being indexed and that the sourcetype mappings to the Authentication data model are unchanged. The admin runs a search against the data model and sees some fields are missing. What is the most likely cause of the 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 data model acceleration needed to be rebuilt after the upgrade.
Option B is correct: After an upgrade, data model acceleration may need to be rebuilt to incorporate any changes; stale acceleration can cause missing fields and lower event counts. Field definitions rarely change between minor upgrades. Permissions would affect visibility, not data content. Index configuration changes would affect all searches, not just data model.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✓
The data model acceleration needed to be rebuilt after the upgrade.
Why this is correct
Correct: Acceleration may become stale after an upgrade; rebuilding it can restore full data.
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 upgrade changed the CIM field definitions, causing some extractions to fail.
Why it's wrong here
CIM field definitions are stable across minor upgrades.
✗
The permissions on the data model were reset during the upgrade.
Why it's wrong here
Permissions affect who sees the model, not the data within.
✗
The index configuration changed, and the data is now in a different index.
Why it's wrong here
If data moved to a different index, raw searches would also be affected, but the admin confirmed indexing unchanged.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

TExam Day Tips
→Underline the problem statement mentally.
→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-1003 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.
