GCDL Practice Question: Reduce its Google Cloud costs without reducing…
This GCDL practice question tests your understanding of reduce its google cloud costs without reducing…. 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 wants to reduce its Google Cloud costs without reducing its workload capacity. The team identifies that several production VMs consistently use less than 30% of their allocated CPU and memory. What is the most straightforward cost optimization action?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Right-size the VMs by migrating to smaller machine types that match actual CPU and memory consumption, reducing costs proportionally
Right-sizing is the direct action. If VMs use 30% of their resources, a smaller machine type that provides the resources actually needed (with some headroom for spikes) costs significantly less. Active Assist proactively surfaces right-sizing recommendations with projected savings.
B
Distractor review
Enable sustained use discounts by ensuring VMs run continuously throughout the month
Sustained Use Discounts apply automatically for VMs that run 25%+ of a month — they don't require any action. They also don't address the over-provisioning problem; they reduce the rate on the same over-sized machine.
C
Distractor review
Purchase Committed Use Discounts for the over-provisioned VMs to reduce their per-hour cost
CUDs reduce the hourly rate but not the fact that you're paying for over-provisioned resources. You'd be committing to paying for idle capacity at a discount — better than full price, but right-sizing eliminates the idle capacity altogether.
D
Distractor review
Delete the under-utilized VMs since low utilization indicates they are no longer needed
Low utilization means VMs are over-provisioned, not unnecessary. The workloads still run on them — they just don't need as many resources as allocated. Deletion would break the workload.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

Question 1
A traditional retailer currently maintains its own data centers, purchasing servers every 3–5 years and paying for facilities, power, and staff regardless of demand. When it migrates its workloads to the public cloud, which change in cost model does it experience?
Question 2
An e-commerce company plans its infrastructure for peak shopping events (e.g., Black Friday) which drive 50× normal traffic. On-premises, they must maintain 50× capacity year-round. In the cloud, they provision 50× capacity only during peak periods. Which cloud characteristic enables this cost optimization?

Question 4
When a company moves from maintaining its own data center to using Google Cloud, which operational responsibility does Google assume that the company previously managed?
Question 5
A hospital runs a patient records system that must remain on-premises due to strict regulatory data residency requirements. However, they also want to use cloud-based AI for diagnostic imaging analysis. Which cloud deployment model best describes their architecture?

FAQ
Questions learners often ask
What does this GCDL question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Right-size the VMs by migrating to smaller machine types that match actual CPU and memory consumption, reducing costs proportionally — Right-sizing means adjusting VM machine types to match actual resource consumption. VMs consistently using less than 30% of CPU/memory are over-provisioned — the organization is paying for 70%+ of idle capacity. Moving to smaller machine types that match actual usage reduces costs proportionally. Google Cloud's Active Assist recommends right-sizing actions based on observed utilization data.
What should I do if I get this GCDL question wrong?
Identify which GCDL exam domain this question belongs to, then review the specific concept being tested. Practise related questions in that domain and focus on understanding why each wrong answer is tempting — not just why the correct answer is right.
