Refer to the exhibit. If a hacker on the outside network sends an IP packet with source address 172.30.1.50, destination address 10.0.0.3, source port 23, and destination port 2447, what does the Cisco IOS firewall do with the packet?

The packet is dropped

Explanation:

To see why we need to understand the ACL or Access-control list that is a list of permissions that specify which users can access or modify certain things in a system. Because the source IP  doesn't have any parameter and is just a plain IP and packet the Cisco firewall will drop the packet based on the ACL rules, in other words, the Cisco firewall doesn't have any parameter that allows it to verify the permission-level of the sender, therefore, the packet will drop.
