CompTIA Cloud+ (CV0-004)SecurityMedium
A cloud provider is developing a new service that requires strict isolation between customer data and compute resources at a hardware level to meet stringent regulatory compliance standards. Which cloud deployment model inherently offers the highest degree of physical isolation for compute resources, making it suitable for such requirements?
- ACommunity Cloud
- BPublic Cloud
- CHybrid Cloud
- DPrivate Cloud
Show answer & explanationAnswer & explanation
Correct answer: D. Private Cloud
A private cloud, by definition, is dedicated to a single organization and can be hosted on-premises or by a third party. This model offers the highest degree of physical isolation for compute resources, as the underlying hardware is not shared with other tenants, directly addressing the need for strict hardware-level isolation for compliance.
Why the other options are wrong
- A. Community clouds share infrastructure among a specific community of organizations, which still implies shared physical resources, not the highest degree of isolation for a single customer.
- B. Public clouds use shared infrastructure, meaning physical isolation at the hardware level between different customers is generally not guaranteed.
- C. Hybrid clouds combine public and private clouds, but the public cloud component still shares infrastructure, so it doesn't meet the 'highest degree of physical isolation' for all resources.
Private Cloud
A cloud computing model where computing resources are dedicated to a single organization, providing exclusive access and often higher levels of security and control.
- Dedicated to a single organization
- Exclusive access to resources
- Higher physical isolation and control
Memory trick: Private cloud is your own exclusive digital estate.
