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.
An administrator notices that a scheduled job that queries the cmdb_ci table is taking longer than expected. The job uses a glide query with multiple encoded queries. What is the best approach to improve performance without altering the job's results?
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
✓
Add an index on the fields used in the encoded query conditions.
Adding an index on the fields used in the encoded query conditions directly reduces the number of rows scanned by the database engine when executing the GlideRecord query. This improves query performance without changing the logic or results of the scheduled job, as indexes only affect data access speed, not the data returned.
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.
✗
Create a database view on the cmdb_ci table and query the view instead.
Why it's wrong here
A view does not improve performance; indexing the underlying tables is more effective.
✓
Add an index on the fields used in the encoded query conditions.
Why this is correct
Indexing the filter fields accelerates query execution.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Convert the glide query to a direct database query using System SQL.
Why it's wrong here
Direct SQL bypasses ACLs and is not a supported best practice.
✗
Add an index on the sys_created_on field.
Why it's wrong here
This only helps if the query filters or sorts by creation date.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume creating a view or using direct SQL will magically speed up queries, but ServiceNow's architecture requires proper indexing on the filtered columns to achieve performance gains without breaking platform security or result integrity.
Detailed technical explanation
How to think about this question
ServiceNow uses the underlying MySQL/MariaDB database, where indexes are B-tree structures that allow the database to locate rows without full table scans. When a GlideRecord query includes multiple encoded queries (e.g., 'active=true^category=hardware'), a composite index on those exact columns can drastically reduce query time, especially on large CMDB tables like cmdb_ci that often contain millions of records. Without proper indexing, the database performs a full table scan, which is the most common cause of slow scheduled jobs.
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.
