Google PCA App Engine Standard Practice Question
Which Google Cloud service provides a fully managed, auto-scaling environment for running stateless HTTP(S) web applications using a variety of supported programming languages?
⚠ Common exam trap
Watch out — candidates often confuse App Engine Standard with App Engine Flexible, which offers more customization but is not fully managed in the same way, or they mistakenly think Cloud Functions can serve persistent web applications, but Cloud Functions is limited to stateless, event-driven functions with a maximum timeout of 9 minutes and no support for persistent HTTP sessions.
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
✓
App Engine Standard
App Engine Standard is the correct choice because it is a fully managed, auto-scaling platform specifically designed for stateless HTTP(S) web applications. It supports multiple programming languages (e.g., Python, Java, Go, PHP, Node.js) and automatically handles scaling, load balancing, and patching, allowing developers to focus on code without managing infrastructure.
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 Functions
Why it's wrong here
Cloud Functions runs single-purpose event-driven functions with a short execution timeout and no persistent HTTP server, so it cannot host a stateless web application. It is tempting because it is fully managed and autoscaling, and suits lightweight API endpoints or event handlers.
- ✗
Google Kubernetes Engine
Why it's wrong here
Google Kubernetes Engine manages clusters, but you still containerise the app and configure deployments, services and autoscaling, so it is not a fully managed application platform. It is tempting when portability across clouds or fine-grained orchestration control is required.
- ✗
Compute Engine
Why it's wrong here
Compute Engine provides raw virtual machines, leaving OS patching, runtime installation and autoscaling configuration to you, so it is not fully managed for HTTP(S) apps. It is tempting when full control of the guest OS is required, such as custom kernel modules or licensed software.
- ✓
App Engine Standard
Why this is correct
App Engine Standard runs stateless HTTP(S) applications on a fully managed platform that scales instances automatically, including down to zero, and supports runtimes for Java, Python, Go, Node.js, PHP and others. This matches the stem's managed, auto-scaling, multi-language requirements.
