Certified Ethical Hacker (CEH v11) — Question 300

Your organization has signed an agreement with a web hosting provider that requires you to take full responsibility of the maintenance of the cloud-based resources.
Which of the following models covers this?

Answer options

• A. Platform as a service
• B. Software as a service
• C. Functions as a service
• D. Infrastructure as a service

Correct answer: D

Explanation

The correct answer is D, Infrastructure as a service (IaaS), because this model provides the most control over the underlying cloud infrastructure, requiring the user to manage the maintenance. The other options, such as Platform as a Service and Software as a Service, involve more management by the provider, thus not aligning with the requirement of full responsibility for maintenance.
