To create a training sandbox with 160MB of test data that needs to be refreshed every other day, NTO should use either Partial or Developer Pro sandboxes. Partial sandboxes have a storage limit of 10GB and can be refreshed every 5 days. Developer Pro sandboxes have a storage limit of 1GB and can be refreshed every day. Both sandboxes can include test data from production. Reference: https://help.salesforce.com/s/articleView?id=sf.data_sandbox_environments.htm&type=5

Setting a debug log on the Automated Process entity allows capturing information about platform events that are published or subscribed by flows or processes. This can help debug issues related to platform events and flows.

The flow debug option is a tool that allows you to test and troubleshoot your flow by running it in debug mode and inspecting the values of variables and resources at each step. You can also set the debug mode to run as another user and see how the flow behaves for different users with different permissions and settings. In this case, using the flow debug option and setting the selection to run as another user can help identify why one user is experiencing a flow error while others are not.

Identity verification history and login history are two areas that the administrator can review to understand potential root causes of multi-factor authentication issues. Identity verification history shows the methods and results of identity verification attempts for a user, such as email verification, SMS verification, or app verification. Login history shows the status, source, and location of login attempts for a user, as well as any login errors or challenges that occurred. These two areas can help the administrator identify if the user entered the correct verification code, if the user's device or app is compatible with multi-factor authentication, or if there are any network or security issues that prevent successful verification.

To ensure that sales reps' managers can view records containing customer's credit information but their colleagues cannot, NTO should grant access using hierarchies via the sharing settings. This option allows users above another user in the role hierarchy to have access to records owned by or shared with users below them in the hierarchy.
