CompTIA Server+ (SK0-004) — Question 58

A technician is having problems sending a notification from a server. The technician suspects the firewall may be blocking traffic. Which of the following clients can be used to confirm the technician's suspicions?

Answer options

• A. traceroute
• B. sendmail
• C. nslookup
• D. telnet

Correct answer: A

Explanation

The correct answer is A, traceroute, as it helps determine the path taken by packets to reach a destination and can reveal if the firewall is blocking traffic. B, sendmail, is used for sending emails, C, nslookup, is for DNS queries, and D, telnet, is for testing connectivity to specific ports, but they are not suitable for confirming firewall-related issues.
