Deploying and implementing a cloud solutionmediumMultiple ChoiceObjective-mapped

Quick Answer

The answer is the command `gcloud container clusters create prod-cluster --region=us-central1 --num-nodes=3 --enable-autoscaling --min-nodes=3 --max-nodes=10`. This is correct because the `--enable-autoscaling` flag activates the GKE cluster autoscaler, which dynamically adjusts the node pool size based on workload demand, while `--min-nodes=3` and `--max-nodes=10` define the scaling boundaries, and `--num-nodes=3` sets the initial count to match the minimum. On the Google Associate Cloud Engineer exam, this tests your ability to distinguish cluster autoscaling from node auto-repair or auto-upgrade, and a common trap is forgetting that `--num-nodes` must equal the minimum to avoid an immediate resize. Remember the mnemonic "MIN and MAX bookend the NUM" — the initial node count should always match the lower bound of your scaling range for a clean start.

This ACE practice question tests your understanding of deploying and implementing a cloud solution. 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 team needs a GKE cluster named 'prod-cluster' in the us-central1 region with cluster autoscaling enabled, scaling between 3 and 10 nodes. Which command achieves this?

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

gcloud container clusters create prod-cluster --region=us-central1 --num-nodes=3 --enable-autoscaling --min-nodes=3 --max-nodes=10

Option A is correct because it uses the `gcloud container clusters create` command with the `--enable-autoscaling` flag, which enables cluster autoscaler for the GKE cluster. The `--min-nodes=3` and `--max-nodes=10` flags define the scaling range, while `--num-nodes=3` sets the initial node count, ensuring the cluster starts with 3 nodes and can scale up to 10 as needed. The `--region=us-central1` specifies a regional cluster, which is appropriate for production workloads requiring high availability across zones.

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.

  • gcloud container clusters create prod-cluster --region=us-central1 --num-nodes=3 --enable-autoscaling --min-nodes=3 --max-nodes=10

    Why this is correct

    This command creates a regional GKE cluster with the node autoscaler configured to scale between 3 and 10 nodes. `--region` creates a regional (multi-zone) cluster.

    Clue confirmation

    The clue word "which command" in the question point toward this answer.

    Related concept

    Read the scenario before looking for a memorised answer.

  • gcloud kubernetes clusters create prod-cluster --location=us-central1 --autoscale=3:10

    Why it's wrong here

    `gcloud kubernetes` is not a valid command group — use `gcloud container`. `--autoscale=3:10` is not a valid flag syntax.

  • gcloud container cluster create prod-cluster --zone=us-central1 --scaling=3-10

    Why it's wrong here

    `cluster create` is missing the plural `clusters`. `--zone=us-central1` is a region, not a zone. `--scaling` is not a valid flag.

  • kubectl create cluster prod-cluster --region=us-central1 --autoscale --min=3 --max=10

    Why it's wrong here

    `kubectl` manages resources within an existing cluster — it cannot create GKE clusters. Use `gcloud container clusters create`.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Google Cloud often tests the distinction between `gcloud container clusters` (correct for GKE) and `gcloud kubernetes clusters` (invalid), as well as the requirement to use `--enable-autoscaling` with separate `--min-nodes` and `--max-nodes` flags instead of shorthand syntax like `--autoscale=3:10`.

Trap categories for this question

  • Command / output trap

    `gcloud kubernetes` is not a valid command group — use `gcloud container`. `--autoscale=3:10` is not a valid flag syntax.

Detailed technical explanation

How to think about this question

The GKE cluster autoscaler works by monitoring pod resource requests and automatically adjusting the node pool size within the defined min and max bounds. It integrates with the Kubernetes scheduler to detect unschedulable pods due to resource constraints and triggers node addition, while removing underutilized nodes after a cooldown period (default 10 minutes). In a regional cluster, nodes are distributed across multiple zones in the region (e.g., us-central1-a, us-central1-b, us-central1-c), providing fault tolerance; the autoscaler scales node pools per zone independently to maintain balance.

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.
