Google ACE Deploying and implementing a cloud solution Practice Question

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.

Exhibit

apiVersion: apps/v1
kind: Deployment
metadata:
  name: web-app
spec:
  replicas: 3
  selector:
    matchLabels:
      app: web
  template:
    metadata:
      labels:
        app: web
    spec:
      containers:
      - name: web
        image: us.gcr.io/my-project/web-app:1.0
        resources:
          requests:
            memory: "6Gi"
            cpu: "1"
          limits:
            memory: "12Gi"
            cpu: "2"

Refer to the exhibit. A Deployment is applied to a GKE cluster. The cluster has a single node pool with one node of machine type n1-standard-4 (4 vCPUs, 15 GB memory). After a few minutes, only two Pods are running, and one Pod is in Pending state. The node's resource usage shows 70% CPU allocated and 85% memory allocated. What is the most likely cause of the Pending Pod?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

  • Clue: "most likely"

    Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.

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

✓

The node has insufficient memory because each Pod requests 6 GiB.

The node has 15 GB memory. Two Pods each request 6 GiB, consuming 12 GiB. Only 3 GiB remains, which is less than the 6 GiB needed for the third Pod. CPU: two Pods request 1 vCPU each (2 vCPU total), leaving 2 vCPU for the third, which is sufficient. Therefore, insufficient memory is the cause.

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.

  • ✗

    The node has insufficient CPU because each Pod requests 1 vCPU.

    Why it's wrong here

    Two Pods use 2 vCPU, leaving 2 vCPU, enough for the third Pod's 1 vCPU request.

  • ✗

    The node has not enough IP addresses available.

    Why it's wrong here

    IP address shortage is rare in GKE; the node has a subnet with many addresses.

  • ✗

    The Pods are pending due to a failed image pull.

    Why it's wrong here

    A failed image pull would typically result in an ImagePullBackOff error, not Pending.

  • ✓

    The node has insufficient memory because each Pod requests 6 GiB.

    Why this is correct

    Two Pods consume 12 GiB, leaving 3 GiB, insufficient for the third Pod's 6 GiB request.

    Clue confirmation

    The clue word "most likely" in the question point toward this answer.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

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.
  • Use explanations to understand the rule behind the answer.

TExam Day Tips

  • Underline the problem statement mentally.
  • 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

A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
