CERTIFIED-IN-CYBERSECURITY Question #562: Real Exam Question with Answer & Explanation

Question

Which of the following cloud models require the LEAST administration and support from the organization?

Options

• APlatform as a Service (PaaS)
• BInfrastructure as a Service (IaaS)
• CSoftware as a Service (SaaS)
• DSoftware Defined Networking (SDN)

Explanation

Software as a Service (SaaS) is a cloud computing model that delivers applications over the Internet. In this model, the SaaS provider takes care of all the underlying infrastructure, including servers, storage, networking, and the software application itself. This means that the organization does not have to manage or support these elements (see ISC2 Study Guide, Chapter 4, Module 3). For example, an organization might use a SaaS solution such as Google Workspace or Microsoft 365, which provides access to productivity tools without the need for on-premises servers or software installation. As for the other options, Infrastructure as a Service (IaaS) provides the infrastructure (servers, storage, etc.), but the organization is still responsible for managing the operating systems, applications, and data. Platform as a Service (PaaS) provides the platform and environment for developers to build and deploy applications, but the organization still needs to manage the applications and data. Software Defined Networking (SDN) is an approach to networking that allows network administrators to manage network services by abstracting lower- level functionality. However, it still requires a significant amount of management and support
