Launch PT Hide and Save PT Open the PT Activity. Perform the tasks in the activity instructions and then answer the question. What problem is causing PC-A to be unable to communicate with the Internet? The access list used in the NAT process is referencing the wrong subnet. The static route should not reference the interface, but the outside address instead. The NAT interfaces are not correctly assigned.* This router should be configured to use static NAT instead of PAT. The ip nat inside source command refers to the wrong interface. 4 What is a disadvantage of NAT? There is no end-to-end addressing.* The internal hosts have to use a single public IPv4 address for external communication.

The router does not need to alter the checksum of the IPv4 packets. The costs of readdressing hosts can be significant for a publicly addressed network. 5 Which statement accurately describes dynamic NAT? It provides a mapping of internal host names to IP addresses. It always maps a private IP address to a public IP address. It provides an automated mapping of inside local to inside global IP addresses.* It dynamically provides IP addressing to internal hosts. 6 When dynamic NAT without overloading is being used, what happens if seven users attempt to access a public server on the Internet when only six addresses are available in the NAT pool? All users can access the server. The first user gets disconnected when the seventh user makes the request. The request to the server for the seventh user fails.* No users can access the server. 7 What is the purpose of port forwarding? Port forwarding allows an external user to reach a service on a private IPv4 address that is located inside a LAN.* Port forwarding allows users to reach servers on the Internet that are not using standard port numbers. Port forwarding allows an internal user to reach a service on a public IPv4 address that is located outside a LAN. Port forwarding allows for translating inside local IP addresses to outside local addresses.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
