ServiceNow Certified System Administration Practice

To save changes on an existing record and return to the previously viewed form, clicking the "Update" button is the correct action. When you click "Update," the changes you have made to the record are saved, and you are directed back to the list of records or the previously accessed area. This is particularly useful in ServiceNow as it allows for a seamless workflow, enabling users to complete their tasks efficiently without needing to navigate manually back to the previous screen after saving.

The alternative options describe different functions that involve either saving or creating records but do not specifically link to the requirement of returning to the previous form after saving existing changes. For example, while "Save" may seem like a plausible choice for saving, it typically functions more in a context where you want to stay on the same form to continue making edits. "Create" is unrelated, as it refers to initiating a new record rather than saving modifications to an existing one. The right-click action to "Save" would be a variation to save but may not necessarily fulfill the requirement of returning you to the previous state like the "Update" button efficiently does.
