Exam CSA topic 1 question 41 discussion

dictionary overrides can be used to set field properties in extended tables in ServiceNow. An extended table is a custom database table that is created by extending an existing base table in the platform. When you create an extended table, you can specify which fields from the base table you want to include in the new table, as well as any additional fields that are specific to the extended table. You can use dictionary overrides to modify the properties of fields in an extended table in much the same way as you would for fields in a base table. For example, you might use a dictionary override to change the label or description of a field, or to specify a default value or a custom picker for that field. It is important to note that dictionary overrides apply to the specific field that they are defined for, and do not affect other fields in the same table or in related tables. So if you want to modify the properties of multiple fields in an extended table, you will need to create separate dictionary overrides for each field.

D is correct.

A Dictionary Override is a feature of the ServiceNow platform, which is used for IT service management. It allows customers to update or modify the metadata (dictionary) of a specific table in a ServiceNow instance, even if that table has been customized by the instance owner. This allows for greater flexibility in customization and ensures that customer updates can be easily managed and tracked. In simple terms, a Dictionary Override occurs when a customer updates the metadata of a table in a ServiceNow instance that has already been customized by the instance owner. The customer update is stored separately from the instance owner's customization, and can be easily identified and managed.

D is correct

Dictionary overrides provide the ability to define a field on an extended table differently from the field on the parent table. For example, for a field on the Task [task] table, a dictionary override can change the default value on the Incident [incident] table without affecting the default value on Task [task] or on Change [change]
