Which of the following services is NOT offered by Zabbix LLC and certified partners?

The correct choice, which identifies a service not offered by Zabbix LLC and certified partners, is paste management. Zabbix LLC focuses on monitoring solutions, providing services that support the implementation, maintenance, and optimization of their software. Technical support is provided to assist clients in resolving issues with the Zabbix platform. Remote troubleshooting is another critical service that entails diagnosing and resolving software-related issues from a distance. Template building is also a service offered, as it enables users to create customized templates for monitoring different systems and applications.

In contrast, paste management does not align with Zabbix's core function of system monitoring and management. It is not a recognized service associated with the proper use and administration of Zabbix solutions. Thus, understanding the nature of the services provided by Zabbix helps differentiate essential support functionalities from unrelated tasks.
