Explanation
Data Management is where in Setup they could accomplish this task. Data Management is a section in Setup that allows marketers to manage their data sources, imports, exports, and transfers in Marketing Cloud. Data Management includes a subsection called FTP Accounts, where marketers can create and manage their SFTP users and passwords for secure file transfers.

Explanation
To create a new user to fill in for a campaign manager who is out on parental leave, NTO should disable the campaign manager's user and create a new user. Disabling a user means that NTO can temporarily deactivate a user's access to Marketing Cloud without deleting their user information or settings. Creating a new user means that NTO can add a new user with their own user information and settings. This way, NTO can reuse an existing license without losing any data or configurations from the campaign manager's user. The other options are incorrect because:
* Delete the campaign manager's user and create a new user. This option will create a new user to fill in for a campaign manager who is out on parental leave, but it will also delete the campaign manager's user information and settings permanently. This means that NTO will lose any data or configurations associated with the campaign manager's user, such as roles, permissions, preferences, reports, or dashboards.
* Transfer the campaign manager's permissions to a new user. This option will create a new user to fill in for a campaign manager who is out on parental leave, but it will also transfer the campaign manager's permissions to the new user. This means that NTO will change the access level of both users, which may cause security or compliance issues.
* Deactivate the campaign manager's license and assign it to the new user. This option will create a new user to fill in for a campaign manager who is out on parental leave, but it will also deactivate the campaign manager's license permanently. This means that NTO will reduce their number of available licenses by one, which may affect their future user management.
