Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 170

In which cloud services model is the tenant responsible for virtual machine OS patching?

Answer options

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

Correct answer: A

Explanation

In the IaaS (Infrastructure as a Service) model, users have control over the operating system and are responsible for managing OS updates, including patching. In contrast, UCaaS (Unified Communications as a Service), PaaS (Platform as a Service), and SaaS (Software as a Service) models abstract away these responsibilities, with the service provider handling the underlying infrastructure and applications.
