Exam MTCNA Topic 4 Question 163 Discussion

The log action in MikroTik's firewall does not block or drop packets. Instead, it generates a log entry for packets that match the rule and passes the packet to the next rule in the chain. It is used for monitoring, debugging, or auditing network behavior.
MTCNA Official Course Material - Firewall Filters:
"The action 'log' creates a log entry when a packet matches the rule. It does not terminate or alter the packet's flow. The packet continues to be processed by subsequent rules." Rene Meneses MTCNA Study Guide - Firewall Logging:
"Log action is used to generate logs for matched packets. It does not block or modify traffic." MikroTik Wiki - Firewall Actions:
"log - This action writes matching packets to the log. Logging rules have no effect on the packet's behavior." Hence, Option D is correct: It logs the packet, nothing more.
