200-901 Practice Question: A network technician runs the command 'ping…

A network technician runs the command 'ping 8.8.8.8' from a workstation and receives 'Reply from 192.168.1.1: Destination host unreachable.' What does this indicate?

⚠ Common exam trap

Cisco often tests the distinction between 'Destination host unreachable' (routing issue at a router) and 'Request timed out' (no response received), leading candidates to incorrectly assume the default gateway is misconfigured or that there is no connectivity at all.

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

There is a routing issue beyond the local network.

The 'Reply from 192.168.1.1: Destination host unreachable' message indicates that the local router (192.168.1.1) received the ICMP echo request for 8.8.8.8 but could not find a route to that destination in its routing table. This means the router has a valid path back to the workstation (so the default gateway is reachable), but it lacks a route to the remote network, pointing to a routing issue beyond the local subnet.

Answer analysis

Option-by-option breakdown

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

  • There is a routing issue beyond the local network.

    Why this is correct

    The gateway cannot reach the destination, indicating a routing problem.

  • DNS resolution is failing.

    Why it's wrong here

    The ping used an IP address, so DNS is not involved.

  • The default gateway is misconfigured.

    Why it's wrong here

    The gateway is reachable, so it is not misconfigured.

  • The workstation has no internet connectivity.

    Why it's wrong here

    It is not necessarily the workstation's fault; the gateway is responding.

  • The remote server is down.

    Why it's wrong here

    The message says 'Destination host unreachable' from the gateway, which does not confirm server status.
