Question :-

After attending a CEH security seminar, you make a list of changes you would like to perform on your network to increase its security. One of the first things you change is to switch the RestrictAnonymous setting from 0 to 1 on your servers. This, as you were told, would prevent anonymous users from establishing a null session on the server. Using Userinfo tool mentioned at the seminar, you succeed in establishing a null session with one of the servers. Why is that?
RestrictAnonymous must be set to "2" for complete security
RestrictAnonymous must be set to "3" for complete security
There is no way to always prevent an anonymous null session from establishing
RestrictAnonymous must be set to "10" for complete security
