A network administrator is troubleshooting why a server at 192.168.1.10 is not responding to ping from a workstation at 192.168.1.20. Both devices are on the same subnet. The administrator runs `ping 192.168.1.10` from the workstation and gets 'Request timed out'. However, the server can ping the workstation successfully. What is the MOST likely cause?

The workstation's firewall is blocking outgoing ICMP echo requests.

The workstation's IP address is misconfigured.

The server's firewall is blocking incoming ICMP echo requests.

You are troubleshooting intermittent connectivity to a remote server. You run `ping -n 20 10.0.0.1` and see the following summary: Packets: Sent = 20, Received = 18, Lost = 2 (10% loss). The round-trip times vary from 5 ms to 200 ms. What is the most appropriate conclusion?

The remote server is down because 10% of packets were lost.

The network path is experiencing congestion or an unstable link, causing packet loss and variable latency.

The local network interface is down because of the packet loss.

The remote server's firewall is blocking ICMP packets, causing the loss.
