Custom CI Table Visibility: Setting sys_class_name

This SNOW-CSA practice question tests your understanding of database administration and cmdb. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.

A custom table called 'u_cmdb_ci_application' has been created to extend cmdb_ci. After importing data into this table, the new records do not appear in the 'Configuration Items' module. What is the most likely reason?

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.

A
The 'sys_class_name' field was not set to 'u_cmdb_ci_application' during import.
Without the correct sys_class_name, the records may appear in the base table or not be recognized as the proper class.
B
The import set used the wrong transform map.
Why wrong: Wrong transform map would cause mapping errors, but the records would still appear if they are in the table.
C
The table was created in the wrong application scope.
Why wrong: Application scope affects visibility but usually does not prevent records from appearing in CMDB modules.
D
The user does not have access to the custom table.
Why wrong: Access issues would cause errors, not missing records in the module.

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

✓

The 'sys_class_name' field was not set to 'u_cmdb_ci_application' during import.

The 'Configuration Items' module filters records based on the 'sys_class_name' field to display only those belonging to the cmdb_ci class or its subclasses. When importing data into a custom table that extends cmdb_ci, if the 'sys_class_name' field is not explicitly set to 'u_cmdb_ci_application', the records will inherit a default value (often the base class name) and thus be excluded from the module's view. This is a common requirement for CMDB extension tables to ensure proper classification and visibility.

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

A common misconception is that the Configuration Items module shows all records from any table extending cmdb_ci automatically, but the trap here is that the module relies on the 'sys_class_name' field to filter records, so failing to set this field during import will hide the records even if the table extension is correct.

Detailed technical explanation

How to think about this question

In ServiceNow, the 'sys_class_name' field is a system field that stores the exact table name of the record, enabling polymorphic behavior in CMDB. When a record is created via import, the platform automatically sets 'sys_class_name' to the table name of the import target, but if the import is done via a transform map that maps to a parent table or if the field is omitted, the class may default to the parent. Real-world scenarios often involve importing data from spreadsheets where the 'sys_class_name' column is missing, causing all records to appear under 'cmdb_ci' instead of the custom subclass, leading to confusion in CMDB reporting and discovery.

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.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.

Variation 1. An administrator notices that a custom table 'u_custom_infrastructure' was created as a child of 'cmdb_ci'. However, records in this table are not appearing in the CMDB dashboard reports that show all CIs. What is the likely reason?

hard

A.The table has permissions that restrict report access
B.The records have not passed data certification
C.The table's 'Display in CMDB dashboard' property is disabled
✓ D.The table is not included in the 'CMDB Base Class' report definition

Why D: The CMDB dashboard reports are typically configured to display records from specific base classes or tables. If 'u_custom_infrastructure' is a child of 'cmdb_ci' but is not explicitly included in the 'CMDB Base Class' report definition, the report will not query that table, so its records will not appear. This is a common configuration oversight when extending the CMDB schema.
