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?

To facilitate the troubleshooting process, which inbound ICMP message should be permitted on an outside interface?

Which command is used to activate an IPv6 ACL named ENG_ACL on an interface so that the router filters traffic prior to accessing the routing table?

Which statement describes a typical security policy for a DMZ firewall configuration?

Refer to the exhibit. Which statement describes the function of the ACEs?

When an inbound Internet-traffic ACL is being implemented, what should be included to prevent the spoofing of internal networks?

In addition to the criteria used by extended ACLs, what conditions are used by a classic firewall to filter traffic?

A router has been configured as a classic firewall and an inbound ACL applied to the external interface. Which action does the router take after inbound-to-outbound traffic is inspected and a new entry is created in the state table?

If the provided ACEs are in the same ACL, which ACE should be listed first in the ACL according to best practice?

A company is deploying a new network design in which the border router has three interfaces. Interface Serial0/0/0 connects to the ISP, GigabitEthernet0/0 connects to the DMZ, and GigabitEthernet/01 connects to the internal private network. Which type of traffic would receive the least amount of inspection (have the most freedom of travel)?

Refer to the exhibit. The ACL statement is the only one explicitly configured on the router. Based on this information, which two conclusions can be drawn regarding remote access network connections? (Choose two.)

Consider the following

access list.access-list 100 permit ip host 192.168.10.1 any

access-list 100 deny icmp 192.168.10.0 0.0.0.255 any echo

access-list 100 permit ip any any
