Answers
C.
The primary DNS server is 8.8.8.8.
D.
There is a manual entry in the hosts file.
Answers
D.
There is a manual entry in the hosts file.
Suggested answer: D

Explanation:

The most likely reason for this result is that there is a manual entry in the hosts file that maps the FQDN to an incorrect IP address (104.18.17.32). The hosts file is a text file that contains mappings of hostnames or domain names to IP addresses, which are used by the operating system to resolve names before querying DNS servers on the network or internet. The hosts file can be used to override DNS settings or block access to certain websites by redirecting them to different IP addresses, such as localhost (127.O.O.l) or invalid addresses (O.O.O.O). If there is a manual entry in the hosts file that conflicts with DNS records, it can cause name resolution errors or connectivity issues.
