Selected Answer: C

Since the error message indicates that the ping request could not find the host, the issue likely relates to DNS resolution. Pinging the internal name server helps verify whether the DNS server is reachable and functioning properly. If the internal DNS server is not reachable or not working correctly, it would prevent domain names from being resolved to IP addresses, leading to the error reported. A. Ping 127.0.0.1 to test local hardware: This tests the local loopback interface to ensure the TCP/IP stack is functioning, but it does not address DNS resolution issues directly. B. Test the website from outside the company: While this can confirm if the website is accessible externally, it does not directly address the internal DNS resolution problem. D. Check internet firewall logs for blocked DNS traffic: This could be relevant if there were specific indications of DNS issues, but verifying internal DNS server functionality is a more immediate step to identify if DNS resolution is the problem.
