Which two statements are true about the firewall filter configuration shown in the exhibit?

The exhibit illustrates the configuration of a firewall filter named mgmt_fill and its subsequent application to an interface. The first true statement is that the filter is applied to a physical interface . The configuration shows the filter attached to me0 , which in Junos nomenclature represents the Management Ethernet port—a dedicated physical port for out-of-band management traffic. This is separate from logical or virtual interfaces, as me0 provides the physical link for administrative access.

The second true statement is that the filter evaluates SSH packets egressing from the management interface . In the provided snippet, term t1 specifically matches the destination-port ssh , and the filter is applied to the interface unit. When a filter is applied to an interface, it can monitor traffic entering or leaving the device. Furthermore, the filter utilizes a count action (count c1), which is a non-terminating action used to provide telemetry on specific traffic types passing through that physical port. There is no mention of a syslog or log action in the configuration, meaning that while packets are counted, they are not being written to the system log files. This configuration is a standard method for hardening the management plane and tracking administrative session activity on the Routing Engine.
