• A. Commit
• B. Preview
• C. Retrieve
• D. Test

Answer: (C)

The first step when applying an update set in ServiceNow is to preview the update set. Previewing allows you to assess the changes included in the update set before they are applied to the target instance. During this step, ServiceNow checks for any potential conflicts with existing data or scripts, ensuring that the update will not adversely affect the current configuration or functionality of the instance.

By previewing, administrators can review the items that will be modified, added, or deleted, giving them an opportunity to take corrective actions if necessary—such as resolving conflicts or making adjustments—prior to committing the changes to the instance. This step helps maintain system stability and integrity as updates are made.
