QUESTION 8 In Network Address Translation, why does a router assign different source port numbers in addition to converting local addresses to the external NAT IP address when forwarding datagrams externally (as opposed to keeping the original port numbers)? The port numbers are effectively being used to identify local hosts, and re-assigning port numbers helps to avoid any collisions wherein two hosts in the subnet are sending external requests with the same source port number. O Because NAT takes advantage of the fact that port numbers are also 32 bits long, meaning they can be used as aliases for IP addresses. O Because NAT is a transport layer protocol O Because there is a reserved set of 128 port numbers exclusively for NAT that all outbound datagrams must use. QUESTION 9 Which of the following best describes the action of forwarding? O Moving a datagram from a router's input port to the correct output post so that it can continue on its path to the destination. O Broadcasting a datagram to all hosts to return a response if their IP address matches the one in the request. The transmission of a datagram from one autonomous system (AS) to another via BGP. O Determining an optimal or near-optimal path from the current router to the destination host.
