Explanation
The server administrator needs to adhere to the Service Level Agreement (SLA) when responding to tickets within a certain amount of time. An SLA is a contract between a service provider and a customer that defines the quality, availability, and responsibilities of the service. An SLA may specify the response time for tickets, as well as other metrics such as uptime, performance, security, and backup frequency. Reference:
