CompTIA Server+ (SK0-005) — Question 32

A server technician has been asked to upload a few files from the internal web server to the internal FTP server. The technician logs in to the web server using
PuTTY, but the connection to the FTP server fails. However, the FTP connection from the technician's workstation is suׁcessful. To troubleshoot the issue, the technician executes the following command on both the web server and the workstation: ping ftp.acme.local
The IP address in the command output is different on each machine. Which of the following is the MOST likely reason for the connection failure?

Answer options

• A. A misconfigured firewall
• B. A misconfigured hosts.deny file
• C. A misconfigured hosts file
• D. A misconfigured hosts.allow file

Correct answer: C

Explanation

The differing IP addresses from the 'ping' command suggest that the web server is resolving the domain name to a different IP than the workstation. This indicates that the hosts file on the web server may have an incorrect entry for ftp.acme.local, leading to the failure in connecting, while the workstation resolves it correctly. The other options are less likely because they would not typically cause a discrepancy in IP resolution.
