Sure, I'd be happy to explain the three firewall filter terminating actions!
Firewall filter terminating actions are the actions taken by a firewall filter when a packet matches a specific filter rule. These actions determine what happens to the packet after it has been processed by the firewall filter.
Here are explanations for the three firewall filter terminating actions you mentioned:
Accept - This action allows the packet to continue its journey through the network. When a packet matches a filter rule with an accept action, the firewall filter allows the packet to proceed to its intended destination. The accept action is used when the packet is considered valid and should be allowed to pass through the firewall.
Reject - This action sends a message to the sender indicating that the packet has been rejected. When a packet matches a filter rule with a reject action, the firewall filter sends an ICMP message to the sender to let them know that their packet has been rejected. The reject action is used when the packet is considered invalid, but the sender should be notified that their packet has been rejected.
Discard/drop - This action drops the packet and doesn't send any notification to the sender. When a packet matches a filter rule with a discard or drop action, the firewall filter simply discards the packet and doesn't send any notification to the sender. The discard/drop action is used when the packet is considered invalid and should be blocked from passing through the firewall without notifying the sender.
Log - This action generates a log message for the packet, which can be useful for troubleshooting or auditing purposes. When a packet matches a filter rule with a log action, the firewall filter generates a log message that contains information about the packet and the filter rule that it matched. The log action is often used in conjunction with another terminating action (such as accept or discard/drop) to generate a log message for packets that match specific filter rules.
Note that you mentioned three actions, but there are actually four options in the exam question. The fourth option, "drop", is a synonym for "discard" and refers to the same terminating action. So, the correct answers are "accept", "reject", and "discard/drop".
