When ServerB contacts a server, which addressing type does it generate for the destination IP address?

The addressing type that ServerB generates for the destination IP address is typically based on the context of the network architecture and the destination device. If ServerB is attempting to contact a server, it needs to know the IP address of the destination server it wants to reach.

In this context, 'HostA' would represent another endpoint in the network that can be directly contacted. When ServerB creates a packet for communication, it determines the destination based on the IP address assigned to the server it is reaching out to. This could refer to a server that is either on the same local network or reachable via routing.

The other options, such as routers or switches, do not represent the final destination that ServerB is trying to contact in terms of IP addressing. Routers are used for directing traffic and managing communication between different network segments, and switches facilitate the connection between devices on the same network segment. However, neither routers nor switches themselves are the destination addresses that ServerB would generate for an outbound communication attempt.

Therefore, the choice that reflects a typical contact for a server's communication is indeed 'HostA', as it denotes a host on the network which ServerB aims to reach directly.
