CompTIA A+ Core 1 (220-1001) — Question 16

A user has reported application connectivity problems to the network administrator. The network administrator knows there have been firewall configuration changes recently by a security vendor and believes the issue could be related to a port being closed on the firewall. Which of the following should the network administrator do NEXT?

Answer options

• A. See if the same application fails on another workstation
• B. Go into the firewall and open the port
• C. Verify system functionality on the user's workstation
• D. Document the issue for future reference

Correct answer: C

Explanation

The correct action is to verify system functionality on the user's workstation to ensure the issue is not local to that machine. Opening a port without confirming the problem could lead to unnecessary changes, and checking another workstation may not directly address the user's specific issue. Documentation is important but not the immediate next step in troubleshooting.
