QUESTION 5 Suppose you connect your laptop into a university network (either via wired ethernet or 802.11 wifi). How does your laptop get assigned an IP address with which it can send datagrams across the internet? Every student is assigned a unique and static IP address for every laptop or device they register with IT. The laptop sends out a special ethernet (or 802.11) frame asking all hosts within the subnet to return their IP addresses. The laptop is free to select any IP address that is not in the returned IP address list. O IP addresses are unique to each NIC, and therefore, a device does not need to take any action to obtain an IP address. The laptop sends out a DHCP request over UDP to the local DHCP server to obtain an available IP address. QUESTION 6 Which of the following is a disadvantage of using IPV6 addresses when sending datagrams in the network layer? With the rate at which smart devices with connectivity are being produced, we will run out of unique IPV6 addresses in the next five to ten years. A router that services both IPV4 and IPV6 will often have namespace resolution issues wherein some addresses cannot be resolved as being traditional IPV4 or IPV6. Very few routers are capable of supporting datagrams with IPV6 addresses. Those that do support it are often prohibitively expensive and only used by top- tier internet companies (e.g., Google). In order to pass through a network with routers not supporting IPV6, we must use tunneling and carry the extra overhead of having both an IPV6 and traditional IP header. QUESTION 7 Which of the following is true when a host is on a subnet that is separated from the rest of the internet via a router implementing NAT? The host can send outbound datagrams to hosts outside of the subnet, but cannot receive responses. The host cannot send (or receive) data to another host outside of the subnet without first encrypting any datagrams. O A remote host outside of the subnet cannot initiate a TCP connection with the host inside the subnet. The host can send an outbound datagram to a remote host outside of the subnet without any risk of IP spoofing.
