A packet is evaluated against three user-defined terms within a firewall filter and no match is
found.
What correctly describes the action the firewall filter will take for this packet?
A.
The filter will permit the packet and take no additional action.
B.
The filter will reject the packet and send an ICMP message back to the sender.
C.
The filter will discard the packet and take no additional action.
D.
The filter will permit the packet and write a log entry to the firewall log.
Explanation:
The default action for packets not explicitly permitted through a firewall filter is discard.
If a packet passes through all the terms in the filter without a match, the packet is discarded.
