CSA Database Schema and Tables 3

Question 1

Which of the following is TRUE about the 'Task' table (task) in ServiceNow?

Accepted Answer

It is a base table that Incident, Problem, and Change all extend

Answer

The Task table is the foundational base class in ServiceNow; Incident, Problem, Change Request, and many other tables extend it, inheriting its common fields.

Question 2

What happens to data in a ServiceNow table field when you change the field's maximum length to a shorter value via the dictionary?

Accepted Answer

Existing data is unaffected; the constraint applies only to new records

Answer

Reducing a field's max length in the dictionary does not alter or truncate existing data — it only enforces the new constraint on records saved after the change.

Question 3

In ServiceNow, which access control mechanism governs whether a user can read or write a specific field on a table?

Accepted Answer

Both A and B

Answer

ACL rules enforce server-side read/write permissions on fields, while Data Policies can additionally make fields mandatory or read-only based on conditions.

Question 4

What is the maximum number of characters a 'String' field in ServiceNow can store by default (without using a 'Large' field)?

Accepted Answer

255

Answer

Standard String fields in ServiceNow default to a maximum of 255 characters; for longer text you must use Large Text or change the max length.

Question 5

A ServiceNow administrator wants to add a custom column to the 'Incident' table. Which method is recommended?

Accepted Answer

Adding the field through the Table's dictionary in Studio or the Dictionary module

Answer

Custom fields should always be added through ServiceNow's Dictionary editor or Studio, ensuring proper metadata, upgrade safety, and scope tracking.
