Answer:
A. Service type field
Explanation:
QoS is an acronym for quality of service. It is used for real-time multimedia streaming service or technology such as internet protocol television (iptv), voice over internet protocol (voip), videotelephony, multi-player internet games etc.
QoS services are protocols that allow routers to make decisions about which IP datagram may be more important than others. The IP header field where QoS details would be found is a service type field. A service type field typically referred to as, type of service (TOS) is an eight (8) bits field which is used to specify details about quality of service (QoS). It basically defines or assigns IP precedence to the individual IP packets on a network.
Answer:
c. Service oriented architecture (SOA)
Explanation:
In a service oriented architecture (SOA), a component of an application provides services to other components of the application or other applications majorly via a communications protocol over a network. In other words, SOA is a programming or software development technique in which services communicate with each other across different platforms.
One key principle of SOA is to design an application (which in itself is a piece of software with multiple features) that is independent of any product, service, vendor or technology but can be integrated into other applications. SOA makes use of loose coupling - a technique in which a client service remains independent of another service that requires it.
In contrast, a monolithic architecture aims at developing a software that is self-contained, independent and not to be integrated into other applications.
On another hand, Software as a service (SaaS), though a bit similar to SOA, is a model in which an application is made available to customers basically through a network. Users basically access the application via a browser.
Therefore, the best option is
C. Service oriented architecture.
