350-401 Question #460: Real Exam Question with Answer & Explanation

Question

How does an on-premises infrastructure compare to a cloud infrastructure?

Options

• AOn-premises can increase compute power faster than cloud
• BOn-premises requires less power and cooling resources than cloud
• COn-premises offers faster deployment than cloud
• DOn-premises offers lower latency for physically adjacent systems than cloud.

Explanation

On-premises infrastructure generally provides lower latency for physically adjacent systems compared to cloud infrastructure, which involves network transit to remote data centers.

Common mistakes.

• A. Cloud infrastructure offers elastic scalability, allowing compute power to be increased on-demand much faster than procuring and deploying physical hardware in an on-premises environment.
• B. On-premises infrastructure requires organizations to directly manage and pay for all power and cooling resources for their data centers, while cloud infrastructure shifts this burden to the cloud provider.
• C. Cloud infrastructure allows for rapid provisioning of resources in minutes or hours, significantly faster than the procurement, installation, and configuration timelines typical for on-premises deployments.
