When creating a custom table in ServiceNow, the platform automatically assigns a table name prefixed with 'u_' to differentiate custom tables from out-of-the-box (OOB) tables.

Naming Convention for Custom Tables:

The default prefix 'u_' is applied to all custom global tables.

The table name follows the format: 'u_' + [custom name].

Example:

If you create a table named 'abc', the system assigns it the table name: u_abc.

Why 'C. u_abc' is Correct?

All custom tables created by users automatically receive the 'u_' prefix.

Prevents conflicts with ServiceNow's internal tables.

Ensures custom tables are easy to identify.

Explanation of Incorrect Options:

A . snc_abc -- Incorrect

'snc_' is not used for custom tables; it is reserved for internal ServiceNow functionality.

B . abc -- Incorrect

Custom tables do not use raw names; they always include a prefix (u_).

D . sys_abc -- Incorrect

'sys_' is reserved for system tables (e.g., sys_user, sys_db_object).
