Show answer and explanation
Correct answer: A
Explanation
When diagnosing network issues involving access to specific websites, DNS settings are the most logical starting point. If the DNS server cannot resolve the domain name of the problematic website, the user will not be able to access it. This makes checking DNS settings the first and most critical step.
- A. Correct.
DNS settings are a primary factor when a user can access some websites but not others, as improper name resolution can prevent access to specific sites.
- B. Incorrect.
The IP address configuration is important but does not directly relate to accessing some websites while others work fine. This is unlikely to be the root cause in this scenario.
- C. Incorrect.
Firewall settings could block a specific website, but this would typically be a secondary check after confirming DNS settings.
- D. Incorrect.
Internet speed issues could cause slow loading of websites but would not selectively prevent access to only one website.
