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.

Exhibit

```json
{
  "name": "Linux Server Probe",
  "table": "cmdb_ci_linux_server",
  "condition": "sys_class_name=cmdb_ci_linux_server AND operational_status=1",
  "fields": ["name", "serial_number", "cpu_type"],
  "source": "ServiceNow Discovery"
}
```

Refer to the exhibit. What is the purpose of the 'condition' field in this discovery probe?

A
It defines the condition under which the probe triggers.
Why wrong: Probes are triggered by schedules, not conditions.
B
It specifies the condition for identifying duplicates.
Why wrong: Duplicate identification is handled by identification rules.
C
It filters which discovered CIs should be updated by this probe.
The condition restricts the probe's updates to CIs matching the criteria.
D
It limits the probe to only query the database for existing records matching the condition.
Why wrong: The probe does not query based on this condition; it uses it to update existing CIs.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

It filters which discovered CIs should be updated by this probe.

In ServiceNow discovery probes, the 'condition' field is used to filter which discovered CIs should be updated by the probe. It acts as a predicate that evaluates against the discovered CI's attributes; only CIs that match the condition will have their fields updated by the probe's actions. This prevents the probe from overwriting CIs that do not meet specific criteria, ensuring targeted and accurate CI updates.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse the 'condition' field with the probe's trigger condition or with the identification rule, leading them to select option A or B, when in fact it is a post-discovery filter for updates.

Detailed technical explanation

How to think about this question

Under the hood, the condition field in a ServiceNow discovery probe is evaluated against the CI's attributes after the probe has collected data from the target (e.g., via SNMP, WMI, or SSH). If the condition evaluates to false, the probe skips the update operation for that CI, but the probe still runs and may create new CIs or perform other actions. This is particularly useful in multi-source discovery scenarios where you want to update only certain CIs (e.g., only Windows servers with a specific OS version) without affecting others.

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.
