Your network contains an FTP server that runs Windows Server 2008 R2. You create an FTP site on
the server and allow Read access for all users. You create an IIS Manager user account for a user
named User1. You need to ensure that User1 can connect to the FTP site. What should you do?

A.
Enable FTP user isolation

B.
Enable Basic authentication

C.
Add an FTP authorization rule

D.
Add a custom provider for FTP authentication

Explanation:

IIS Manager Authentication
IIS Manager authentication is a custom authentication method that requires users to provide a valid
IIS Manager user name and password to gain access to content. IIS Manager authentication requires
that the IIS Management Service is installed and configured to use both Windows credentials and IIS
Manager credentials. (The IIS Management Service does not have to be running when you use IIS
Manager authentication.)
