CompTIA A+ Core 2 (220-1002) — Question 297

A technician is able to connect to a website; however, the technician receives the following error when attempting to access a different website: Page cannot be displayed. Which of the following command line tools would be BEST to identify the root cause of the connection problem?

Answer options

• A. ipconfig
• B. tracert
• C. nslookup
• D. netstat
• E. ping

Correct answer: C

Explanation

The correct answer is C, nslookup, as it is used to query DNS records and can help determine if the domain name of the problematic website is resolving correctly. Other tools like ipconfig provide network configuration details, tracert traces the route to a destination, netstat shows active connections, and ping checks connectivity, but none directly address DNS resolution issues.
