Frank wants to know why users on the corporate network cannot receive multicast transmissions from the Internet. An NGX Security Gateway protects the corporate network fromt he Internet Which of the following is a possible cause for the connection problem?

A.
NGX does not support multicast routing protocols and streaming media through the Security Gateway

B.
Frank did not install the necessary multicast license with SmartUpdate, when he upgraded to NGX

C.
The Multicast Rule is below the Stealth Rule. NGX can only pass multicast traffic, if the Multicast Rule is above the Stealth Rule

D.
Multicast restrictions are not configured properly on the corporate internal network interface properties of the Security Gateway object

E.
Antispoofing is enabled. NGX cannot pass multicast traffic, if a ntispoofing is enabled

Explanation:
Not D: N GX doesn’t support multicast? That’s quite obviously not true.
