What type of infrastructure allows Zahara's data center to use additional computing power seamlessly?

• A. Private cloud
• B. Public cloud
• C. Hybrid cloud
• D. Virtualized network

Answer: (C)

The correct answer is the hybrid cloud. A hybrid cloud infrastructure combines elements of both private and public clouds, enabling Zahara's data center to use additional computing power seamlessly by leveraging resources from both environments. This means that when there is a spike in demand or the need for extra resources arises, Zahara can quickly access additional computing power from the public cloud while keeping sensitive data and critical operations secure within their private cloud environment.

This setup provides greater flexibility and scalability, allowing seamless integration of on-premises resources with off-premises cloud services. As workloads fluctuate, Zahara can optimize costs and performance by distributing them across the two cloud models, adapting quickly to changing business needs. This versatility is essential for modern data centers that require agility in resource management.

Other options, like private cloud, public cloud, and virtualized network, do not provide the same level of seamless integration of computing resources from both private and public sources. A private cloud is dedicated and typically limited to a single organization, a public cloud offers shared resources over the internet to multiple users but lacks control over the data's residence, and a virtualized network refers to the abstraction of network resources without directly addressing the computing power and scalability requirements.
