Which network issue is suggested by a workstation being unable to connect to certain private network hosts despite being on the same subnet?

1. Invalid MAC address

2. Default gateway issue

3. IP conflict

4. Incorrect routing table

The correct answer is: Incorrect routing table

The situation described, where a workstation is unable to connect to certain private network hosts despite being on the same subnet, indicates a potential problem with the routing of packets within that subnet. A correctly functioning network should allow all devices on the same subnet to communicate with each other directly, without the need for routing through a gateway. In this case, if the workstation is unable to reach specific hosts, it suggests that the routing table may not have the correct entries for those destinations. This could prevent the workstation from sending the necessary data packets to the intended private hosts. A routing table defines the paths that packets take to reach their destinations, and if these paths are misconfigured or incomplete, communication issues will arise. The other potential issues, such as an invalid MAC address, a default gateway issue, or an IP conflict, would likely result in more widespread connectivity problems, rather than isolated inability to connect to certain hosts within the same subnet. Addressing the routing table would be a critical step in troubleshooting this specific connectivity problem, ensuring that the workstation can correctly identify how to reach its intended communication partners on the network.
