CompTIA Cloud Essentials+ (CLO-002)Business Principles of Cloud EnvironmentsHard
A government agency is planning to migrate its legacy record-keeping system to a cloud environment. Due to strict regulatory requirements and concerns about data sovereignty, the agency needs to ensure that all data remains within national borders and that the cloud infrastructure is completely isolated from other tenants. Furthermore, the agency requires direct control over the virtualization layer and operating system of its instances. Which cloud deployment model and service model combination would best satisfy these stringent requirements?
- AHybrid Cloud and SaaS
- BPublic Cloud and PaaS
- CPrivate Cloud and IaaS
- DCommunity Cloud and FaaS
Show answer & explanationAnswer & explanation
Correct answer: C. Private Cloud and IaaS
A Private Cloud ensures complete isolation and data residency within national borders, as the infrastructure is dedicated. When combined with Infrastructure as a Service (IaaS), the agency retains direct control over the virtualization layer and operating system, which is crucial for meeting stringent regulatory and control requirements.
Why the other options are wrong
- A. Hybrid Cloud involves public components which might violate isolation/sovereignty. SaaS offers no control over the OS or virtualization.
- B. Public Cloud shares infrastructure and does not guarantee isolation or direct control over virtualization. PaaS abstracts the OS.
- D. Community Cloud shares resources with others, failing isolation. FaaS abstracts the OS and virtualization layer, providing no direct control.
Private Cloud & IaaS
A dedicated cloud infrastructure for a single organization (Private Cloud) combined with Infrastructure as a Service, providing virtualized resources and control over OS and network.
- Full isolation and control
- Meets strict data sovereignty
- User manages OS and applications
Memory trick: When 'Strict Control' and 'Isolation' are key, think 'Private' as your own fort and 'IaaS' as having the keys to every room.
