IT Aspect of Quality of Service (QoS) - What Does Not Fall Under "IT"?

B.

KPIs fall under the "business" aspect of QoS, along with monitoring and measuring of events and business processes.

Services, security, and applications are all core components and concepts of the "IT" aspect of QoS.

The quality of service (QoS) is a set of standards and mechanisms that ensure the availability, reliability, and performance of network-based services. QoS covers a wide range of aspects that affect the overall performance of a network or service. These aspects include the availability, reliability, security, and efficiency of the network or service.

In this context, the "IT" aspect of QoS refers to the information technology infrastructure that supports the network or service. This includes hardware, software, and systems that are used to deliver the network or service. The IT aspect of QoS can affect the availability, reliability, and performance of the network or service.

Applications, services, and key performance indicators (KPIs) all fall under the "IT" aspect of QoS. Applications are software programs that run on the IT infrastructure and provide services to users. Services are the functions or capabilities that are provided by the IT infrastructure. KPIs are metrics that measure the performance of the IT infrastructure and help to identify areas for improvement.

Security, on the other hand, is a separate aspect of QoS that focuses on the protection of the network or service from unauthorized access, malicious attacks, and other security threats. While security is an important aspect of QoS, it is not directly related to the IT infrastructure that supports the network or service. Instead, security is a cross-cutting concern that affects all aspects of QoS.

Therefore, the answer to the question is D. Security, as it does not fall under the "IT" aspect of QoS.
