Google PCA Manage and provision cloud infrastructure Practice Question

This PCA practice question tests your understanding of manage and provision cloud infrastructure. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.

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 VM will have a public IP address.

Option C is correct because the Deployment Manager template in the exhibit includes the property `autoDelete: true` for the accessConfigs block, which configures a one-to-one NAT on the network interface. This automatically assigns an ephemeral external IP address to the VM, giving it a public IP address. The presence of `type: ONE_TO_ONE_NAT` under `accessConfigs` is the key indicator that a public IP is provisioned.

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 VM will be created in the us-central1-b zone.

    Why it's wrong here

    The zone is explicitly set to us-central1-a.

  • ✗

    The VM will use a custom machine type.

    Why it's wrong here

    n1-standard-4 is a predefined machine type.

  • ✓

    The VM will have a public IP address.

    Why this is correct

    The ONE_TO_ONE_NAT access config assigns an ephemeral external IP.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    The boot disk will not be deleted when the VM is deleted.

    Why it's wrong here

    autoDelete: true means the disk is deleted on VM deletion.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Google Cloud often tests the distinction between predefined and custom machine types, and candidates may mistakenly think any machine type specified with a full path is custom, but the key is the name pattern (e.g., `n1-standard-*` vs. `custom-*`).

Detailed technical explanation

How to think about this question

In Google Cloud Deployment Manager, the `accessConfigs` block with `type: ONE_TO_ONE_NAT` is the mechanism to assign an external IP address to a VM instance. The `autoDelete` property on a disk controls whether the persistent disk is deleted when the instance is deleted; setting it to `true` (as in this template) ensures cleanup, which is critical for cost management in ephemeral environments. The `machineType` field uses a full URL or relative path to reference predefined or custom machine types; `n1-standard-1` is a predefined type, not custom.

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

A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
