Which description of a smurf attack is true?

A. A smurf attack is an attack in which small TCP packets are sent toward a server from thousands of subscribers, which causes the server network buffer to overflow and drop packets and results in a denial of service.

B. A smurf attack is an attack in which the attacker sends ICMP echo request packets using a spoofed source IP address destined to remote network broadcast addresses, which results in all recipients replying back to the spoofed source IP address in an attempt to cause a denial of service to the targeted spoofed IP address.

C. A smurf attack is an attack in which the attacker sends UDP echo packets using a spoofed source IP address destined to remote network broadcast addresses, which results in all recipients replying back to the spoofed source IP address in an attempt to cause a denial of service to the targeted spoofed IP address.

D. A smurf attack is an attack in which the attacker attempts to change the TCP MSS value to a small value for all TCP flows destined to the target device, which results in many small packets having to be processed by the target, which causes buffer overflows and denial of service.

When the failure handling mode is configured as Terminate, which behavior is expected on the GGSN when the OCS sends the diameter result code=4012 within the MSCC in CCA-U message?
