In a simple star-connected Ethernet LAN, where an Ethernet switch is used as a learning switch with an empty switch table.
In a star-connected Ethernet LAN, all computers are connected to a central Ethernet switch. When computer C sends an Ethernet frame to computer C', the switch analyzes the frame's destination MAC address. As it is a learning switch with an initially empty switch table, it does not have any information about the MAC addresses of the connected computers.
When the switch receives the frame from computer C, it checks its destination MAC address and doesn't find it in the switch table. Since the switch doesn't know which interface is associated with the destination MAC address of C', it floods the frame out of all its interfaces, including the one connected to computer B. However, computer B's network interface card (NIC) checks the destination MAC address and determines that the frame is not intended for it. Hence, computer B does not process or receive the frame.
Similarly, when computer C' replies back to computer C, the switch once again floods the frame out of all its interfaces, including the one connected to computer B. But computer B's NIC recognizes that the frame is not addressed to it and does not receive or process it.
Therefore, in this scenario, none of the two frames sent between computers C and C' are received at computer B's interface.

"DDOS attacks take place by
a. using IP addresses as a Trojan horse
b. consuming server bandwitdth
c. placing an excessive load on an electric grid
d. removing permissions for authorized users"
DDoS attacks primarily take place by consuming server bandwidth. They involve overwhelming a target system or network with an influx of traffic from multiple sources, causing it to become inaccessible or perform poorly.
This is achieved by utilizing a large number of compromised devices, often forming a botnet, to flood the target with an enormous amount of data packets.
DDoS attacks do not involve using IP addresses as a Trojan horse. The use of IP addresses in these attacks is related to the fact that attackers often spoof or falsify the source IP addresses of the traffic they generate, making it difficult to trace the origin. However, the IP addresses themselves are not used as a Trojan horse.
Regarding the other options, DDoS attacks do not directly target electric grids or aim to remove permissions for authorized users. Their main objective is to disrupt or deny access to a specific service or network by overwhelming its resources.
