A. B. C. D.A.
The best next step for the technician is to test the theory that the issue is related to DNS. This can be done by attempting to browse to a website's known IP address.
Explanation:
DNS (Domain Name System) is a protocol used to translate domain names (such as www.example.com) into IP addresses (such as 192.0.2.1) that computers use to communicate with each other over the Internet. If there is an issue with DNS, a user may not be able to browse the Internet as expected.
Option A suggests that the technician should test the theory by attempting to browse to a website's known IP address. This test can help the technician confirm whether or not the issue is related to DNS. If the website can be accessed using its IP address but not its domain name, this suggests that there may be an issue with DNS resolution.
Option B suggests that the technician should manually assign a DNS server to the user's computer as a preventive measure. While this may resolve the issue, it is not the best next step as it does not help the technician identify the root cause of the issue.
Option C suggests that the technician should identify the problem by running the command ipconfig /flushdns. This command clears the DNS cache on the user's computer and can help resolve issues related to DNS resolution. However, it is not the best next step as it does not confirm whether or not the issue is related to DNS.
Option D suggests that the technician should document the findings in the organization's local knowledge base. While this is important for knowledge sharing and future reference, it is not the best next step as it does not help the technician resolve the issue at hand.
Therefore, the best next step for the technician is to test the theory by attempting to browse to a website's known IP address.
