If users cannot access a new server by name, what should be examined first?

• A. DHCP server
• B. DNS records
• C. Firewall logs
• D. Network switches

Answer: (B)

When users cannot access a new server by name, the first thing to examine is the DNS records. The Domain Name System (DNS) is responsible for resolving human-readable domain names (like server names) into IP addresses, which are used for routing traffic on the network. If the new server's name has not been properly registered in DNS, clients will not be able to resolve that name to an IP address, resulting in access issues. By checking the DNS records, you can ensure that the new server's hostname is correctly configured and associated with the right IP address. If the DNS entry is missing or misconfigured, it can lead to the inability of users to reach the server by its designated name. While DHCP, firewall logs, and network switches may play roles in connectivity issues, the core problem in this scenario revolves around the name resolution process handled by DNS. If users can access the server by IP address but not by name, this further confirms that the issue is likely with the DNS configuration rather than the other components.
