SNOW-CSA Database Administration and CMDB Practice Question
This SNOW-CSA practice question tests your understanding of database administration and cmdb. 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 responsible for the CMDB at a large enterprise. The CMDB is used for change management and incident management. Recently, during a major incident, it was found that several critical CIs were missing from the CMDB, causing delays in troubleshooting. Further analysis reveals that the Discovery probes were not running on those devices due to schedule conflicts. You need to ensure that all critical devices are discovered regularly. What is the most effective solution?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a dedicated Discovery schedule for critical devices with a higher frequency.
Option C is correct because creating a dedicated Discovery schedule for critical devices ensures they are discovered at a higher frequency without being affected by schedule conflicts that impact the general discovery schedule. This approach guarantees that critical CIs are consistently updated in the CMDB, which is essential for effective change and incident management. By isolating critical devices into their own schedule, you avoid the overhead of increasing frequency for all devices while meeting the specific requirement for regular discovery of critical assets.
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.
✗
Manually add the missing CIs and set a reminder to check every week.
Why it's wrong here
Manual processes are error-prone and do not guarantee regular discovery.
✗
Use horizontal discovery to prioritize critical devices.
Why it's wrong here
Horizontal discovery discovers many devices in a range, but does not provide scheduled priority.
✓
Create a dedicated Discovery schedule for critical devices with a higher frequency.
Why this is correct
A dedicated schedule ensures critical devices are discovered consistently regardless of other schedules.

✗
Increase the frequency of Discovery schedules for all devices.
Why it's wrong here
This would strain resources and may not resolve the specific scheduling conflict for critical devices.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse 'horizontal discovery' (which expands discovery scope) with 'prioritization' or 'scheduling,' leading them to select Option B, when in fact horizontal discovery does not address frequency or schedule conflicts.
Detailed technical explanation
How to think about this question
ServiceNow Discovery uses schedules defined in the Discovery Schedules module, which can be configured with specific IP ranges, credentials, and probe types. By creating a dedicated schedule for critical devices, you can set a higher frequency (e.g., every 2 hours) and assign it to a separate discovery worker or MID server to avoid conflicts with the main schedule. This approach leverages the 'Schedule' field in the Discovery Definition, allowing you to run multiple discovery jobs concurrently without interference, ensuring critical CIs are always up-to-date in the CMDB.
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.
