How does Java applet filtering distinguish between trusted and untrustedapplets?

A.
Examines the applet for suspicious code.

B.
Relies on a list of applets that you designate as hostile.

C.
Relies on a list of applets that you designate as friendly.

D.
Relies on a list of external sites that you designate as friendly.

Explanation:

Java inspection enables Java applet filtering at the firewall. Java applet filtering distinguishes between trusted and untrusted applets by relying on a list of external sites that you designate as “friendly.” If an applet is from a friendly site, the firewall allows the applet through. If the applet is not from a friendly site, the applet will be blocked. Alternately, you could permit applets from all sites except for sites specifically designated as “hostile.”
