Show Answer
Correct Answer: AC

Term 1 specifies that UDP traffic using the 16000 port will be placed in the voice forwarding class with a high loss priority. Term 3 specifies that SSH traffic using the default port (22) will be placed in the af forwarding class without an explicit action, implying that the packet is accepted. Therefore, UDP traffic using the 16000 port will be placed in the voice forwarding class and accepted. Similarly, SSH traffic using the default port will be placed in the af forwarding class and accepted.

Not sure, but for me it is B & D. For SSH and traffic UDP port 16000 there is assigned af group in terms, however there is no terminating action like accept/reject. So the packet is processed to next terms and last term set the ssh traffic and UDP port 16000 packets to best effort.

"forwarding-class <class-name>" is a non-terminating action with implicit accept. "Firewall filters support different sets of nonterminating actions for each protocol family, which include an implicit accept action. In this context, nonterminating means that other actions can follow these actions whereas no other actions can follow a terminating action."
