This PCA practice question tests your understanding of manage implementation of cloud architecture. 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 startup wants to deploy a containerized application with minimal operational overhead. They expect variable traffic. Which compute option should they choose?
App Engine Flexible Environment
Why wrong: Requires configuration and has more overhead than Cloud Run.
Cloud Run
Fully managed serverless container platform that auto-scales.
Compute Engine single VM
Why wrong: Requires manual scaling and management of the VM.
Google Kubernetes Engine (GKE)
Why wrong: Requires cluster management and overhead.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Cloud Run
Cloud Run is the correct choice because it is a fully managed serverless compute platform that automatically scales from zero based on traffic, charges only for resources used during request processing, and eliminates all infrastructure management. This aligns perfectly with the startup's requirement for minimal operational overhead and handling variable traffic patterns without provisioning or scaling concerns.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
App Engine Flexible Environment
Why it's wrong here
Requires configuration and has more overhead than Cloud Run.

Google Kubernetes Engine (GKE)
Why it's wrong here
Requires cluster management and overhead.
Common exam traps
The trap here is that candidates often confuse Cloud Run with App Engine Flexible Environment, assuming both are fully managed, but App Engine Flexible Environment does not scale to zero and requires VM-level management, making Cloud Run the only option that truly minimizes operational overhead for variable traffic.
Detailed technical explanation
Cloud Run executes containers in a sandboxed environment using gVisor, and each revision can scale to thousands of instances based on incoming HTTP requests, with a default concurrency of 80 requests per container instance. Under the hood, it uses Knative serving and Istio for traffic routing, allowing for rapid cold starts (typically under 1 second) and a 15-minute request timeout, which is critical for bursty workloads like web APIs or event-driven microservices.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
