Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  Infrastructure as a Service (IaaS)

  Why it's wrong here

  Infrastructure as a Service (IaaS) provides fundamental computing resources such as virtual machines, storage, and networking components over the internet. While it offers significant flexibility and control, the customer remains fully responsible for installing, configuring, and managing the operating system, middleware, runtime environments, and the application itself, including all necessary patching and security updates for those layers. This model would require the technician to handle OS and platform patching, which contradicts the implied need for a managed platform.

• ✓

  Platform as a Service (PaaS)

  Why this is correct

  Platform as a Service (PaaS) delivers a complete, managed environment for developing, running, and managing applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. The cloud provider manages the operating system, database, web servers, and programming language execution environment, including all patching and updates. This allows the technician to focus entirely on the application code and data, abstracting away the underlying infrastructure management and patching responsibilities.

• ✗

  Software as a Service (SaaS)

  Why it's wrong here

  Software as a Service (SaaS) delivers a complete, ready-to-use application directly to end-users over the internet, typically on a subscription basis. The entire application stack, from infrastructure to the application itself, is managed by the cloud provider, and users simply access the software via a web browser or client application. This model is designed for consuming a finished product, not for deploying custom applications or providing a platform for development, as the customer has no control over the underlying platform.

• ✗

  Desktop as a Service (DaaS)

  Why it's wrong here

  Desktop as a Service (DaaS) provides virtualized desktop environments to end-users, accessible from various devices and locations. Its primary purpose is to deliver a consistent, secure, and centrally managed workspace for users, centralizing desktop management and reducing hardware costs. DaaS is entirely focused on user productivity and desktop delivery, making it irrelevant for deploying server-side cloud-based applications or providing a development platform.
