VoIP(Voice over Internet Protocol) 서비스만 제공하는 조직이 ISP(인터넷 서비스 공급자) SLA(서비스 수준 계약)를 협상할 때 가장 중요한 것은 무엇입니까?
정답: B
The most important factor when negotiating an Internet service provider (ISP) service-level agreement (SLA) by an organization that solely provides Voice over Internet Protocol (VoIP) services is Quality of Service (QoS) between applications. An ISP SLA is a contract that defines the expectations, responsibilities, and guarantees between an ISP and a customer, regarding the delivery and performance of the internet services. An ISP SLA can include various terms and conditions, such as availability, reliability, speed, latency, throughput, or security of the internet services, and the metrics, measurements, and penalties for the compliance or non-compliance of the ISP SLA. QoS is a term that describes the ability of a network or a service to provide the desired level of performance, efficiency, and satisfaction for the applications or the users that use the network or the service. QoS can be influenced by various factors, such as bandwidth, latency, jitter, or packet loss, and it can be measured by various metrics, such as delay, throughput, or error rate. QoS between applications is the QoS that is achieved or maintained between the applications that communicate or interact over the network or the service, such as VoIP applications. QoS between applications is the most important factor when negotiating an ISP SLA by an organization that solely provides VoIP services, as VoIP services are highly sensitive and dependent on the QoS between applications, and any degradation or variation in the QoS between applications can affect the quality, functionality, and usability of the VoIP services.
