Which of the following components, when added, can enable host A to ping host B?
Explanation
Answer: B - To enable host A to ping host B, you would need to connect the two switches to a router using straight through cables.
Key Takeaway: A router is a device that forwards data packets to their destinations, based on the address specified on the packet. When a packet of data arrives at a router, its header information is scrutinized by the router. Based on the destination and source IP addresses of the packet, the router decides which neighbor it will forward it to. It chooses the route with the least cost and forwards the packet to the first router on that route. To enable pinging between 2 hosts, the switches should be connected using straight-through cables.
