Selected Answer: C
Is this really a question on the test? This is painfully unclear. Notice how the tech is able to ping IP addresses, but says nothing about resolving DNS names. I would assume it's a static, or, as the answers offer, an incorrect DHCP scope option for DNS before I'd assume the firewall is blocking all web traffic on a workstation. ...then again I'm probably overthinking it.

C. The answer is C. The incorrect DNS address was assigned. When a computer cannot access a web page, the first thing to check is the DNS settings. DNS is a system that translates domain names into IP addresses. If the DNS settings are incorrect, the computer will not be able to resolve the domain name of the web page and will be unable to access it.

It isn’t trying to access a webpage, it’s trying to use a web based application.

Actually it states the technician confirmed the computer can not reach any web pages.

C I cannot find any valuable info about firewall blocking access. But there are numerous DNS settings and cache cleaning.

if you have internet access but cannot access web pages : Check your network settings Custom proxy or DNS settings can affect your ability to access content on the internet. You can check your network settings, or even try disabling browser extensions one by one to see if they're interfering with your connection. Clear your cache Outdated DNS information in your computer's cache can prevent you from accessing websites.
