Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 143

Which cloud service model offers an environment for cloud consumers to develop and deploy applications without needing to manage or maintain the underlying cloud infrastructure?

Answer options

• A. PaaS
• B. XaaS
• C. IaaS
• D. SaaS

Correct answer: A

Explanation

The correct answer is PaaS (Platform as a Service) because it allows developers to focus on application development without worrying about the underlying hardware or software layers. In contrast, IaaS (Infrastructure as a Service) requires management of infrastructure, SaaS (Software as a Service) delivers software applications over the internet, and XaaS (Anything as a Service) is a broader term that encompasses various service models.
