Question
A company is migrating its email server to a cloud provider. The technician needs to ensure high availability. Which cloud model should be implemented?
A. IaaS
B. PaaS
C. SaaS
D. Hybrid cloud
E. Public cloud
Answer
D. Hybrid cloud
Explanation
A hybrid cloud combines on-premises infrastructure with cloud resources, allowing for high availability by maintaining critical services locally while leveraging cloud scalability and redundancy.
A hybrid cloud model integrates both on-premises infrastructure and cloud-based resources, providing a robust solution for high availability during email server migration. This approach enables critical email services to remain operational locally while leveraging the cloud’s scalability, redundancy, and disaster recovery capabilities.
By distributing workloads between local servers and cloud providers, the hybrid model ensures that if one environment experiences downtime or failure, the other can maintain service continuity, minimizing disruption to business operations. This dual setup is especially valuable for organizations needing both tight data control and the flexibility to scale or recover quickly.
Public cloud alone offers scalability but less control, while on-premises solutions lack the inherent redundancy and failover capabilities of a hybrid deployment. Hybrid cloud is therefore the recommended model for high availability in business-critical email migrations.
