Which type of user authentication is configured?

A user wants to establish an FTP session to a server behind an SRX device but must authenticate to a Web page
on the SRX device for additional authentication. Which type of user authentication is configured?

A.
pass-through

B.
WebAuth

C.
WebAuth with Web redirect

D.
pass-through with Web redirect

Explanation:
Web authentication is valid for all types of traffic. With Web authentication configured, users must first
directly access the Junos security platform using HTTP. The user enters the address or hostname of the device
into a Web browser and then receives a prompt for a username and password. If authentication is successful,
the user can then access the restricted resource directly. Subsequent traffic from the same source IP address is
automatically allowed access to the restricted resource, as long as security policy allows for it.
