Setup audit trail is a tool that allows administrators to review recent configuration changes made in their org. It shows a list of up to 180 days of setup changes made by anyone in the org, including the date, time, user, and type of change. It can help administrators track who made what changes and when, and troubleshoot any issues caused by configuration changes. Critical updates are notifications that inform administrators of new features or enhancements that may impact their org; they do not show configuration changes made by users. Debug logs are records of database operations, system processes, and errors that occur when executing a transaction or running unit tests; they do not show configuration changes made by users either. Field history tracking is a feature that allows administrators to track changes to the values of certain fields on records; it does not show configuration changes made in setup.

A flow can be active or inactive depending on whether you want it to run or not. An inactive flow cannot be run by users or processes until you activate it. If a flow in production is supposed to create new records but it is not doing so, it could be because the flow is inactive and needs to be activated.

IP address restrictions allow you to prevent users from accessing Salesforce from outside of their network. You can set IP address restrictions on the profile level or globally for the org. To enforce IP restrictions for API logins, you must select Enforce Login IP Ranges on Every Request in Session Settings.

Split views are a feature that allows users to view records as a split list on object home pages in Lightning Experience apps that use console navigation. Split views show records in two panes: a list view pane on the left and a record detail pane on the right. Users can switch between different list views and records without losing context or scrolling. However, split views are only available on standard objects such as accounts, contacts, leads, opportunities, cases, etc., and not on custom objects such as shipments.

A validation rule is a tool that allows administrators to enforce data quality and integrity by preventing users from saving records that do not meet certain criteria or conditions. For example, a validation rule can display an error message if a user enters an invalid value in a field. In this case, the administrator can create a validation rule on the account object that displays an error if the account annual revenue field is below 0 or greater than 100 billion.
