GED Reasoning Through Language ArtsReading ComprehensionEasy
A technician is troubleshooting a network issue. The client reports that they cannot access a specific internal company website, but can browse external sites like Google. The technician checks the client's local network settings and finds that the DNS server is configured correctly. Which of the following is the MOST likely next step for the technician to take?
- AReinstall the operating system on the client's computer.
- BReplace the client's network interface card (NIC).
- CCheck the company's internal DNS server for proper resolution of the website's domain.
- DAdvise the client to use a different web browser.
Show answer & explanationAnswer & explanation
Correct answer: C. Check the company's internal DNS server for proper resolution of the website's domain.
Since the client can access external sites but not an internal one, and their local DNS settings are correct, the problem likely lies with the internal DNS server's ability to resolve the specific internal website's domain name. Checking the internal DNS server is the logical next step.
Why the other options are wrong
- A. Reinstalling the OS is a drastic measure and highly unlikely to be necessary for this specific problem. (Incorrect)
- B. If the NIC were faulty, the client would likely not be able to access any network resources, internal or external. (Incorrect)
- D. The browser is unlikely to be the cause if other external websites work fine; this suggests a network resolution issue, not a browser compatibility one. (Incorrect)
DNS Resolution Process
The process by which a domain name (like example.com) is translated into an IP address (like 192.0.2.1) that computers use to identify each other on a network.
- Starts with a client query.
- Involves multiple types of DNS servers.
- Ends with an IP address being returned.
Memory trick: DNS: Don't Neglect Servers when clients can't connect.
