CompTIA A+ 220-1101 Practice Question

Software as a Service (SaaS) is the correct answer because it refers to cloud-based software that is hosted online by a service provider and made available to customers over the internet. SaaS frees organizations from maintaining software on their own hardware and managing infrastructure, as all of that is managed by SaaS providers. Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet and typically requires customers to manage their own software, including applications and operating systems. Platform as a Service (PaaS) provides customers with a platform to develop, run, and manage applications, but does not typically offer full software solutions for end-users.
