Why each option

DNS settings on Cisco Unified Communications Manager (CUCM) are fundamental network configurations and must be changed by opening an SSH session to each individual node in the cluster and using command-line interface (CLI) commands. These critical settings cannot be modified via the web GUI.

AFind the DNS setting in the system parameter settings in the Network section

System parameter settings in the Network section of the GUI typically cover other network-related parameters but not the core DNS server configuration.

BGo to System > Network > DNS settings

There is no direct "System > Network > DNS settings" menu in the Cisco UCM web GUI for modifying DNS server addresses.

CGo to Network > IP > Cisco Serviceability and change the DNS settings

Cisco Serviceability is primarily for troubleshooting, tracing, and monitoring services, not for modifying fundamental network configurations like DNS server addresses.

DOpen an SSH session to each node in the Cisco UCM cluster and change the DNS setting usingCorrect

DNS settings are a critical network configuration for Cisco UCM nodes, and for security and stability reasons, they cannot be modified through the web-based administrative interface (Cisco Unified CM Administration or OS Administration). Instead, an administrator must establish an SSH session to each individual node in the CUCM cluster and use specific CLI commands (e.g., set network dns primary <IP>) to update these settings.
