This PCD practice question tests your understanding of deploying applications. 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.
Which TWO statements about Cloud Run for Anthos are correct? (Choose 2)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Cloud Run for Anthos allows users to autoscale their containerized applications without worrying about underlying GKE nodes.
Option A is correct because Cloud Run for Anthos leverages the Knative Serving autoscaler to automatically scale container instances up or down based on incoming request traffic, including scaling to zero when idle. This autoscaling operates at the pod level within the GKE cluster, abstracting away the underlying node management from the user.
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 Run for Anthos allows users to autoscale their containerized applications without worrying about underlying GKE nodes.
Why this is correct
Correct: The service handles scaling of the containers, though nodes need separate management.
Related concept
Read the scenario before looking for a memorised answer.
✗
Cloud Run for Anthos is a multi-region service by default.
Why it's wrong here
It is deployed on a specific GKE cluster, which is regional unless you have a multi-region cluster.
✗
Cloud Run for Anthos supports only HTTP requests, not gRPC.
Cloud Run for Anthos runs on GKE clusters and uses Knative Serving.
Why this is correct
Correct: It is built on Knative and runs on GKE.
Related concept
Read the scenario before looking for a memorised answer.
✗
Cloud Run for Anthos requires you to bring your own load balancer.
Why it's wrong here
It integrates with GKE ingress and can use provided load balancers.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that Cloud Run for Anthos is a fully managed serverless service like Cloud Run on Google Cloud, when in fact it requires a GKE cluster and provides more control over the underlying infrastructure, including support for gRPC and custom load balancing.
Detailed technical explanation
How to think about this question
Under the hood, Cloud Run for Anthos uses the Knative Serving resource definitions (Service, Configuration, Revision, Route) to manage deployments and traffic routing. The autoscaler calculates concurrency metrics from the Envoy sidecar proxy and adjusts the number of pods via the Kubernetes Horizontal Pod Autoscaler, with a target concurrency default of 80 requests per container. This allows fine-grained control over scaling behavior, such as setting a maximum number of containers or configuring the scale-down delay.

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.
