Choose two
  • A SSH traffic using the default port will be placed in the af forwarding class and accepted.
  • B SSH traffic using the default port will be placed in the best-effort forwarding class and accepted.
  • C UDP traffic using the 16000 port will be placed in the voice forwarding class and accepted.
  • D UDP traffic using the 16000 port will be placed in the best-effort forwarding class and accepted.
Explanation

In Junos stateless firewall filters, packets that match a term containing only nonterminating actions are accepted by default unless the term specifies another terminating action. TCP port 22 matches term 3 and is placed in the af forwarding class. UDP port 16000 matches term 1 and is placed in the voice forwarding class. The final best-effort accept term handles traffic that did not match an earlier term.
