Cloud Digital Leader Fundamental cloud concepts Practice Question
This GCDL practice question tests your understanding of fundamental cloud concepts. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
Which TWO of the following are common use cases for deploying workloads to the cloud? (Choose 2)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Running a global SaaS application for customers worldwide
Option D is correct because cloud platforms like AWS, Azure, and GCP provide global infrastructure with multiple regions and edge locations, enabling SaaS applications to serve customers worldwide with low latency via CDNs and load balancers. Option E is correct because cloud storage services (e.g., Amazon S3, Azure Blob Storage) offer durable, cost-effective off-site backup and automated disaster recovery through replication across Availability Zones or Regions, often with 99.999999999% durability.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
Cloud introduces network latency that may not meet HFT requirements.
✗
Air-gapped, classified workloads with no internet connection
Why it's wrong here
Cloud requires connectivity, so air-gapped workloads are not suitable.
✗
Running a legacy mainframe application that requires dedicated hardware
Why it's wrong here
Mainframes often need specific hardware not typically available in cloud.
✓
Running a global SaaS application for customers worldwide
Why this is correct
Cloud enables global distribution and easy scaling.

✓
Data backup and disaster recovery
Why this is correct

Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the misconception that 'cloud is suitable for all workloads,' but the trap here is that candidates may select options like A or C because they sound like 'advanced' use cases, failing to recognize that cloud's shared infrastructure and network dependency make it unsuitable for ultra-low-latency or air-gapped scenarios.
Detailed technical explanation
How to think about this question
Cloud providers achieve global SaaS delivery through a combination of Anycast DNS (e.g., Amazon Route 53), global load balancers (e.g., AWS Global Accelerator), and content delivery networks (e.g., CloudFront) that route users to the nearest healthy endpoint. For backup and disaster recovery, cloud object storage uses erasure coding (e.g., 11/9 scheme in Azure) to reconstruct data from fragments, and cross-region replication (CRR) in S3 can automatically copy objects to a secondary region, enabling RPOs as low as 15 minutes without custom scripting.
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.
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.
