Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Community cloud
Why it's wrong here
A community cloud is shared infrastructure serving organisations with common concerns, such as compliance or mission, not two separate public providers used for redundancy. Deploying identical workloads across AWS and Azure to avoid lock-in is multi-cloud. Community cloud would suit several hospitals jointly consuming a shared, governed platform.
- ✗
Hybrid cloud
Why it's wrong here
Hybrid cloud combines private infrastructure with public cloud services, or on-premises systems with cloud, integrated via secure connectivity. Here two public providers host the same application independently, which is a multi-cloud deployment. Hybrid would fit a scenario extending an on-premises data centre into Azure for burst capacity or gradual migration.
- ✗
Private cloud
Why it's wrong here
A private cloud is dedicated infrastructure operated for a single organisation, whether on-premises or hosted, so it cannot describe workloads running on two separate public providers. The scenario is multi-cloud, using AWS and Azure independently for redundancy. Private cloud would fit an organisation requiring exclusive control over its compute and storage.
- ✓
Multi-cloud
Why this is correct
Multi-cloud means deliberately using two or more distinct public cloud providers, here AWS and Azure, for the same workload. This satisfies the redundancy, lock-in avoidance and disaster recovery constraints, unlike hybrid cloud, which pairs public cloud with private infrastructure.
