A network engineer is troubleshooting a problem where a server cannot communicate with remote servers outside of its network.

The engineer verifies that the server can ping its loopback address, its own IP address, and the default gateway without any issues. However, attempts to ping remote servers time out. The engineer suspects a routing issue.

What should the network engineer check first to diagnose the problem?

The IP address configuration on the remote servers.

The routing table on the router for any incorrect or missing routes.

The server's firewall settings for any rules blocking ICMP packets.

The physical network connections between the server and the router.
