CompTIA A+ Core 1 (220-1001) — Question 66

A user reports being unable to browse the Internet. A technician believes the cause of the issue is related to DNS.
Which of the following should the technician perform NEXT?

Answer options

• A. Test the theory by attempting to browse to a website's known IP address.
• B. Implement preventive measures by manually assigning a DNS server to the PC.
• C. Identify the problem by running the command ipconfig /flushdns.
• D. Document the findings in the organization's local knowledge base.

Correct answer: A

Explanation

The correct answer is A because testing access to a website's known IP address helps determine if the issue is DNS-related. Options B and C may help resolve the issue but do not directly test the DNS theory. Option D is not a troubleshooting step but rather a documentation task that should be done after the issue is resolved.
