Palo Alto Networks Cybersecurity Entry-Level Technician (PCCET) — Question 19

In which two cloud computing service models are the vendors responsible for vulnerability and patch management of the underlying operating system? (Choose two.)

Answer options

• A. SaaS
• B. PaaS
• C. On-premises
• D. IaaS

Correct answer: A, B

Explanation

The correct answers are A (SaaS) and B (PaaS) because in these models, the service providers manage the underlying infrastructure, including operating system security updates and vulnerability management. In contrast, C (On-premises) requires organizations to manage their own infrastructure, while D (IaaS) provides customers with more control over the operating system, placing the responsibility for patch management on them.
