Question 89 of 507

Fundamental cloud concepts →easyMultiple ChoiceObjective-mapped

Quick Answer

The answer is that on-premises TCO must include physical space or rent, electricity for servers and cooling, cooling system maintenance, physical security, and fire suppression. These facility costs are essential because a self-managed data center requires a dedicated environment with controlled power, climate, and access, all of which represent real operational expenses that are often overlooked when comparing to cloud models like IaaS. On the Google Cloud Digital Leader exam, this concept tests your ability to perform a fair total cost of ownership comparison, emphasizing that cloud shifts these facility burdens to the provider. A common trap is focusing only on hardware and software licenses while ignoring the hidden costs of running a physical facility. To remember, think of the acronym SPACE: Space, Power, Air conditioning, Cooling maintenance, and Entry security.

Cloud Digital Leader Fundamental cloud concepts Practice Question

This GCDL practice question tests your understanding of fundamental cloud concepts. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

A company is comparing the total cost of keeping its data center versus moving to public cloud. An analyst argues that the comparison should include not just hardware costs but also facility costs. What facility costs should be included in the on-premises total cost of ownership calculation?

A
Only the cost of the servers themselves, since other costs are shared across the organization
Why wrong: Allocating only server hardware costs while ignoring facility costs produces an inaccurate TCO that systematically understates on-premises costs. Facility costs must be allocated to the data center to produce a fair comparison.
B
Physical space/rent, electricity (for servers and cooling), cooling system maintenance, physical security, and fire suppression — all of which are real costs borne by the organization for operating its own data center
This is the complete set of facility costs. Power is often the largest ongoing cost after staff. Cooling typically adds 30-50% to the power cost of the IT equipment itself. Physical security and fire suppression add further costs. All must be included for an accurate TCO comparison against cloud.
C
Internet connectivity costs only, since data centers require high-bandwidth connections
Why wrong: Internet connectivity is a relevant cost but is just one component of facility costs. Power, cooling, space, and security are equally or more significant and must also be included.
D
Data center facility costs do not need to be included since they are fixed costs that don't change whether servers are present or not
Why wrong: Facility costs are not sunk costs irrelevant to the comparison. Freeing data center space by moving to cloud can allow facilities to be reduced, subleased, or eliminated — real savings. Fixed costs must be included in TCO to determine whether moving to cloud creates net savings.

Correct answer & explanation

✓

Physical space/rent, electricity (for servers and cooling), cooling system maintenance, physical security, and fire suppression — all of which are real costs borne by the organization for operating its own data center

Option B is correct because a comprehensive on-premises total cost of ownership (TCO) must include all facility-related costs that are directly incurred to operate a data center. These include physical space/rent, electricity for servers and cooling, cooling system maintenance, physical security, and fire suppression. Excluding these costs would understate the true cost of running an on-premises environment, which is a key consideration when comparing to public cloud models like IaaS.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Cisco often tests the misconception that facility costs are either negligible or shared overhead, when in fact they are direct, variable costs that must be included in a proper TCO analysis for on-premises versus cloud comparison.

Detailed technical explanation

How to think about this question

In a data center, facility costs such as power usage effectiveness (PUE) directly impact operational expenses; for example, cooling can account for 30-40% of total electricity consumption. Real-world TCO models, like those from the Uptime Institute, include these costs to show that on-premises TCO often exceeds cloud costs when fully loaded. Subtle behaviors like the need for redundant cooling and fire suppression systems (e.g., FM-200 or Novec 1230) add significant capital and operational costs that are unique to on-premises deployments.

TExam Day Tips

Watch for words such as best, first, most likely and least administrative effort.
Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
