Employees at a newly established satellite office report that they can browse external internet websites normally, but cannot access internal corporate resources using internal domain names such as `intranet.contoso.local`. Network diagnostics confirm that workstations can successfully ping internal servers by their IP address (). Further inspection of client TCP/IP configurations reveals that workstations are dynamically receiving an external public resolver () as their primary DNS server. Which of the following host services or server configurations must be updated to automatically distribute the correct internal DNS server address () to all office clients?
- The DHCP server scope optionsAnswer
- BThe DNS server conditional forwarders
- CThe Web proxy server inbound listening port rules
- DThe client system APIPA configuration settings
Answer
The DHCP server scope options must be modified to distribute the internal DNS server address.
The correct answer identifies the DHCP server scope options. DHCP servers dynamically assign IP configurations to host clients. Through scope options (specifically DNS Server / Option 006), the administrator specifies which DNS server IPs are handed out to clients. Updating this option from the public resolver to the internal DNS server resolves internal domain lookups across the office.
