GCDL Practice Question: A logistics company collects GPS data from 50,000…
This GCDL practice question tests your understanding of a logistics company collects gps data from 50,000…. 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 logistics company collects GPS data from 50,000 trucks every 30 seconds. Previously they sampled only 1% of this data due to storage costs. In the cloud, they store and analyze 100% of the data and discover route optimization patterns that reduce fuel costs by 12%. Which concept does this illustrate about cloud and data?
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
Distractor review
Cloud storage is cheaper per GB than on-premises — the only benefit is cost reduction.
Cost reduction is a factor, but the deeper value is the insights unlocked by analyzing complete data. The 12% fuel savings creates far more value than just the storage cost difference.
B
Distractor review
GPS data is only useful when analyzed by Google's AI — the company's own analytics wouldn't find patterns.
The company uses their own route optimization logic on their data. Cloud provides the infrastructure and data access; the business intelligence comes from the company's domain expertise.
C
Distractor review
The company should have used data sampling more aggressively to reduce cloud costs further.
The business case proves the opposite — full data analysis enabled $X in fuel savings that far exceeds any marginal storage cost savings from additional sampling.
D
Best answer
Cloud scale removes data storage and analysis constraints, enabling companies to derive business insights from complete datasets that were previously too costly to collect and process.
On-premises cost constraints forced data sampling, hiding optimization patterns. Cloud's economics enable full-fidelity data collection and analysis at scale, revealing insights like the 12% fuel savings.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

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 3
Which term describes the process by which organizations integrate digital technology into all areas of their business, fundamentally changing how they operate and deliver value to customers?
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?
Question 6
What is virtualization in the context of cloud computing, and why is it fundamental to how cloud providers deliver services?

FAQ
Questions learners often ask
What does this GCDL question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Cloud scale removes data storage and analysis constraints, enabling companies to derive business insights from complete datasets that were previously too costly to collect and process. — Cloud storage's low cost and scalability removes the data collection constraints that existed on-premises. When companies can store and analyze ALL their data rather than sampled subsets, they discover insights that were previously invisible. This 'data democratization' effect — where cost barriers to data storage and analysis are removed — enables new business insights and improvements that justify the entire cloud investment. The 12% fuel savings illustrates ROI from data insights enabled by cloud scale.
What should I do if I get this GCDL question wrong?
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related GCDL NAT questions on configuration and troubleshooting.
