- A
Software as a Service (SaaS) using Gmail
Why wrong: SaaS delivers ready-to-use software, not a platform for developing custom applications.
- B
Function as a Service (FaaS) using Cloud Functions
Why wrong: Cloud Functions is designed for event-driven, stateless functions, not hosting a complete web application.
- C
Infrastructure as a Service (IaaS) using Compute Engine
Why wrong: IaaS still requires provisioning and managing virtual machines, which does not minimize infrastructure management.
- D
Platform as a Service (PaaS) using App Engine
App Engine automatically scales and manages the runtime environment, allowing developers to focus solely on code.

Cloud Digital Leader Practice Question: A startup needs to quickly deploy a web…
This GCDL practice question tests your understanding of a startup needs to quickly deploy a web…. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. 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 startup needs to quickly deploy a web application with minimal infrastructure management. They want to focus on code, not servers. Which Google Cloud service model is most appropriate?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Platform as a Service (PaaS) using App Engine
App Engine is a fully managed Platform as a Service (PaaS) that abstracts away the underlying infrastructure, allowing developers to deploy web applications without managing servers or operating systems. It automatically handles scaling, load balancing, and patching, which aligns with the startup's requirement to focus on code rather than infrastructure management.
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
Google Cloud often tests the distinction between PaaS and FaaS by presenting a scenario that requires a full web application, where candidates mistakenly choose FaaS (Cloud Functions) because they confuse 'serverless' with 'no infrastructure management,' ignoring that FaaS is unsuitable for long-running HTTP applications with stateful sessions.
Detailed technical explanation
How to think about this question
App Engine uses automatic scaling based on request load, leveraging Google's global network and load balancers to distribute traffic across instances. Under the hood, it supports multiple runtimes (e.g., Python, Java, Go) and provides a sandboxed environment where the runtime is patched and maintained by Google, eliminating OS-level management. In a real-world scenario, a startup could deploy a Flask or Django app with zero configuration for scaling, but must be aware of App Engine's request timeout limits (e.g., 60 minutes for manual scaling) and the absence of a writable filesystem for persistent storage.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
