A desktop workstation was recently relocated from the Finance department subnet () to the Marketing department subnet (). A technician manually configured the network adapter with a static IPv4 address of , a subnet mask of , a default gateway of , and a preferred DNS server of . The workstation can ping adjacent computers on the local network, but users report they cannot reach internal servers on other subnets or access external internet resources. Which of the following configuration changes will resolve the workstation's reachability issue?
- Update the default gateway IPv4 address to an IP address within the subnet, such as .Cevap
- BReconfigure the preferred DNS server to issue a dynamic IPv4 address lease from the pool.
- CConnect an unmanaged Layer 2 switch to the wall jack to route traffic between the and subnets.
- DModify the network adapter settings to change its default transport port assignment from port 80 to port 443.
Cevap
Update the default gateway IPv4 address to an IP address within the local subnet (e.g., ).
For a computer to reach destinations outside its local IP network, it must send traffic to a default gateway router located on its own subnet. Since the computer is on , its default gateway must also have an IP address within the network block (such as ). Setting the default gateway to prevents the host from forwarding off-subnet traffic because the gateway IP address is not directly reachable on the local layer 2 segment.
