SNOW-CSA Database Administration and CMDB Practice Question
This SNOW-CSA practice question tests your understanding of database administration and cmdb. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Which THREE of the following are best practices for CMDB data maintenance? (Choose exactly 3.)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Scheduled reconciliation to identify and merge duplicates
Option A is correct because scheduled reconciliation is a core CMDB best practice that uses identification rules to automatically detect and merge duplicate CIs, ensuring a single source of truth. This process relies on the CMDB's reconciliation engine, which compares CI attributes against defined identification and reconciliation rules to resolve conflicts without manual intervention.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Discovery is key for keeping CMDB updated.
✗
Manually updating all CI attributes
Why it's wrong here
Manual updates are error-prone and not scalable.

Common exam traps
Common exam trap: answer the scenario, not the keyword
ServiceNow often tests the misconception that disabling discovery is a valid maintenance strategy, when in fact it is the opposite; the trap here is confusing 'maintenance' with 'preventing change' rather than 'ensuring data accuracy through automation'.
Detailed technical explanation
How to think about this question
The CMDB reconciliation engine uses a combination of identification rules (which define how CIs are uniquely identified, e.g., by serial number or FQDN) and reconciliation rules (which define how to merge or update attributes from multiple sources). Scheduled reconciliation runs as a job, often using the 'cmdb_reconciliation' scheduled job, and can be configured to run daily or weekly to maintain data integrity. In real-world scenarios, failing to schedule reconciliation can result in duplicate CIs for the same server, causing inaccurate reporting and incident correlation.
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 SNOW-CSA 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.
