Microsoft Azure Fundamentals (AZ-900)Describe cloud conceptsHard
A government agency is implementing a new citizen services portal. Due to legal requirements, all data must reside within the country's borders, and the agency must have complete administrative control over the entire cloud infrastructure, including the physical servers and networking equipment. They also require dedicated resources that are not shared with any other entity. Which cloud model would be the ONLY acceptable option for this scenario?
- APrivate Cloud
- BHybrid Cloud
- CCommunity Cloud
- DPublic Cloud
Show answer & explanationAnswer & explanation
Correct answer: A. Private Cloud
A Private Cloud is the only model that guarantees a single organization has exclusive control over the entire cloud infrastructure, including physical servers, and ensures no shared resources with other entities. This provides the highest level of isolation and control necessary to meet stringent legal requirements for data residency and complete administrative control over physical infrastructure.
Why the other options are wrong
- B. Hybrid cloud combines private and public aspects, which would not meet the 'no shared resources' and 'complete control over physical servers' mandates.
- C. Community cloud involves sharing resources among specific organizations, which violates the requirement for dedicated, unshared resources and complete physical control.
- D. Public cloud involves shared infrastructure and does not offer complete administrative control over physical servers or dedicated resources.
Private Cloud (Exclusive Control)
A cloud deployment model where the infrastructure is exclusively operated for a single organization, providing ultimate control, security, and isolation, often including direct management of physical hardware.
- Dedicated infrastructure for one organization
- Highest level of security and control
- Can be on-premises or off-premises, but always dedicated
Memory trick: Private cloud is your agency's fortress, all yours.
