CompTIA Server+ SK0-005 Practice Question

During a maintenance window a junior administrator provisions a new Linux backup server with a static IPv4 configuration:

IP address: 10.25.10.15/24
Default gateway: 10.25.11.1

After the server is connected to the production access switch, the link LED is lit and the server can successfully ping other hosts on 10.25.10.0/24.
Attempts to ping 10.25.11.1 or any address on another subnet return Destination Host Unreachable, and traceroute stops at the first hop.

Which of the following network misconfigurations is MOST likely preventing the server from reaching remote networks?

  • The default gateway is configured for a different subnet than the server's IP address.

  • An outbound ICMP rule on the perimeter firewall is blocking traffic.

  • The DNS servers are assigned to the wrong VLAN.

  • The NIC has negotiated half-duplex, causing excessive collisions.
