350-401 Question #73: Real Exam Question with Answer & Explanation

Question

What is a benefit of deploying an on-premises infrastructure versus a cloud infrastructure deployment?

Options

• Afaster deployment times because additional infrastructure does not need to be purchased
• Blower latency between systems that are physically located near each other
• Cless power and cooling resources needed to run infrastructure on-premises
• Dability to quickly increase compute power without the need to install additional hardware

Explanation

On-Premises vs. Cloud Infrastructure

Option B is correct because when servers and systems are physically located in the same building or data center, data travels shorter distances, resulting in lower network latency - this is a genuine advantage of on-premises infrastructure that cloud deployments (where data must travel over the internet to remote servers) cannot always match.

Why the distractors are wrong:

• A is incorrect because on-premises deployments actually require purchasing and installing new hardware before deployment, making them slower - this speed advantage belongs to cloud infrastructure.
• C is incorrect because on-premises infrastructure typically requires more power and cooling resources, since the organization bears full responsibility for managing physical hardware.
• D is incorrect because rapidly scaling compute power without installing hardware is a hallmark benefit of cloud infrastructure (elasticity), not on-premises deployments.

Memory Tip: Think of it this way - "On-prem = proximity advantage." Everything else (speed of deployment, scalability, reduced power costs) favors the cloud. The one thing on-premises wins at is keeping data physically close, which minimizes latency. If a question asks about on-premises benefits, think local = low latency.
