What will ServerB generate as a destination MAC address while attempting to contact HostA?

When ServerB attempts to contact HostA, it needs to determine the correct destination MAC address to place in the Ethernet frame that it will send out. If the destination HostA is not in the same local network as ServerB, ServerB will need to send the packet to a router (in this case, RouterB) which is responsible for routing traffic to different networks.

In a typical network configuration, if two devices are on separate subnets, the originating device must reach the default gateway—often a router—for communication across these subnets. When ServerB refers to its routing table and determines that it cannot send the packets directly to HostA due to different subnets, it identifies RouterB as the next hop for its packets.

Thus, ServerB generates RouterB's MAC address as the destination MAC for its outgoing frames. This allows the frame to properly traverse the local network segment to reach RouterB, which will then handle forwarding the packet along the appropriate path to reach HostA. The process of determining the correct MAC address is typically completed using the Address Resolution Protocol (ARP) if the MAC address is not already cached.

In summary, ServerB generates the MAC address of RouterB because it needs to send traffic to HostA through the
