FC0-U71 Practice Question: A network technician is troubleshooting a server…

A network technician is troubleshooting a server that is not reachable from the LAN. The server has a static IP address of 192.168.1.100/24 and a default gateway of 192.168.1.1. The technician pings the gateway successfully but cannot ping the server from another workstation on the same subnet. Which TWO steps should the technician take to resolve the issue?

⚠ Common exam trap

A common mix-up: candidates assume a successful ping to the gateway means the server is fully reachable, overlooking that local subnet communication requires correct subnet mask and adapter settings, not just gateway connectivity.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Verify the network adapter settings on the server

The technician can ping the gateway from the server, confirming Layer 3 connectivity to the router, but cannot ping the server from another workstation on the same subnet. This points to a local configuration issue on the server itself, such as a misconfigured subnet mask, a disabled network adapter, or incorrect IP settings. Verifying the network adapter settings ensures the server's IP address, subnet mask, and default gateway are correctly applied and the adapter is enabled.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Clear the ARP cache on the server

    Why it's wrong here

    ARP cache does not affect incoming pings from other workstations.

  • Replace the network cable

    Why it's wrong here

    Since gateway is reachable, cable is likely fine.

  • Verify the network adapter settings on the server

    Why this is correct

    Misconfigured adapter could cause subnet mismatch.

  • Check DNS resolution for the server

    Why it's wrong here

    DNS is not required for pinging by IP address.

  • Check the server's firewall settings

    Why this is correct

    Firewall may be blocking incoming ICMP requests.
