The correct answer is B. The DHCP server's scope settings are incorrect.. A server receiving a dynamic IP but unable to reach other subnets while still communicating locally points to an issue with its default gateway configuration provided by DHCP.

Question

A new server is brought online and receives a dynamic IP address. The administrator can ping other servers on the same subnet but not other subnets. Which of the following is the MOST likely cause of the problem?

Options

  • AThe WINS server cannot resolve the gateway.
  • BThe DHCP server's scope settings are incorrect.
  • CThe ISP is preventing the administrator from adding a new IP address.
  • DThe DNS server is not resolving the name space properly.

Why each option

A server receiving a dynamic IP but unable to reach other subnets while still communicating locally points to an issue with its default gateway configuration provided by DHCP.

AThe WINS server cannot resolve the gateway.

WINS is used for NetBIOS name resolution and does not affect the ability to route IP traffic to a gateway.

BThe DHCP server's scope settings are incorrect.Correct

If the DHCP server's scope settings are incorrect, it might assign a valid IP address and subnet mask but fail to provide or provide an incorrect default gateway address. Without a correct default gateway, the server cannot route traffic to other subnets, though it can communicate with devices on its local subnet.

CThe ISP is preventing the administrator from adding a new IP address.

An ISP typically manages public IP addresses and external connectivity, not internal network routing issues for a server receiving a dynamic IP within a private network.

DThe DNS server is not resolving the name space properly.

DNS resolves hostnames to IP addresses; a DNS issue would affect name resolution, not the ability to ping by IP address to other subnets.
