Refer to the exhibit. A network administrator discovers that host A is has a trouble with internet connectivity, but the server farm has full connectivity. In addition, host A has full connectivity to the server farm. What is a possible cause of this problem?

An incorrect subnet mask causes a host to misidentify which networks are local versus remote. Host A can communicate with the server farm because the incorrect mask makes it appear local, but internet traffic fails because routing decisions become invalid. The gateway address is correct (proven by server farm connectivity), but the subnet mask causes the host to apply wrong network boundaries.
