The correct answer is to set 'Extends' to 'Incident' and configure the 'Application' field to the desired scope while checking 'Display in application navigator.' Setting 'Extends' to 'Incident' establishes the inheritance relationship, allowing the new table to automatically inherit all fields, business rules, and behaviors from the Incident table, which itself extends Task. Configuring the 'Application' field ensures the table belongs to the correct application context, and enabling 'Display in application navigator' makes the table visible in the navigator menu—this directly addresses the search intent for "extended table navigator visibility." On the ServiceNow Certified Application Developer CAD exam, this tests your understanding of table inheritance and application scoping, often appearing as a scenario where a developer must ensure a custom table both inherits correctly and appears in the navigator. A common trap is forgetting to set the application scope, which can hide the table from the navigator even if inheritance is correct. Memory tip: "Extend for fields, scope for sight"—inheritance gives you the data, application scope gives you the visibility.
SNOW-CAD Creating and customizing tables and data Practice Question
This SNOW-CAD practice question tests your understanding of creating and customizing tables and data. 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 developer is creating a new table 'u_incident_custom' to extend the Incident table. Which TWO configurations will ensure that the new table inherits the correct behavior and displays in the application navigator?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set 'Application' to the desired scope and check 'Display in application navigator'
Option A is correct because setting 'Application' to the desired scope ensures the table belongs to the correct application context, and checking 'Display in application navigator' makes the table visible in the application navigator menu. Option D is correct because setting 'Extends' to 'Incident' establishes the inheritance relationship, allowing the new table to inherit all fields, business rules, and behaviors from the Incident table, which itself extends Task.
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.
✓
Set 'Application' to the desired scope and check 'Display in application navigator'
Why this is correct
This ensures the table is scoped correctly and appears in the navigator.
Related concept
Read the scenario before looking for a memorised answer.
✗
Create a module pointing to the new table
Why it's wrong here
Modules are for custom navigation; the table will appear automatically under its parent if configured.
✗
Set 'Label' to 'Incident Custom'
Why it's wrong here
Label is for display only and does not affect inheritance.
✓
Set 'Extends' to 'Incident'
Why this is correct
Extending the parent table ensures inheritance of fields, business rules, and ACLs.
Related concept

✗
Set 'Extends' to 'Task'
Why it's wrong here
Extending Task would not inherit Incident-specific behavior like state model.
Common exam traps
Common exam trap: answer the scenario, not the keyword
ServiceNow often tests the distinction between table inheritance (Extends field) and navigator visibility (Display in application navigator), and candidates mistakenly think that setting a label or creating a module alone will achieve inheritance or navigator display.
Detailed technical explanation
How to think about this question
In ServiceNow, table inheritance is implemented via the 'Extends' field in the dictionary, which creates a parent-child relationship where the child table inherits all columns, business rules, ACLs, and UI policies from the parent. The 'Display in application navigator' checkbox sets the 'sys_db_object.display' field to true, which controls whether the table appears as a menu item in the application navigator; without this, the table exists but is hidden from the navigator. A common real-world scenario is creating a custom incident table for a specific business unit (e.g., 'u_incident_custom') that needs to inherit all incident workflows but appear separately in the navigator for that team.

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-CAD 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.

What is the correct answer to this question?
The correct answer is: Set 'Application' to the desired scope and check 'Display in application navigator' — Option A is correct because setting 'Application' to the desired scope ensures the table belongs to the correct application context, and checking 'Display in application navigator' makes the table visible in the application navigator menu. Option D is correct because setting 'Extends' to 'Incident' establishes the inheritance relationship, allowing the new table to inherit all fields, business rules, and behaviors from the Incident table, which itself extends Task.
