Google PCA ONE_TO_ONE_NAT 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. A key principle to apply: oNE_TO_ONE_NAT. 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 includes the property `type: ONE_TO_ONE_NAT` under the `accessConfigs` block, which configures a NAT on the network interface and automatically assigns an ephemeral external IP address to the VM, giving it a public IP address.

Key principle: ONE_TO_ONE_NAT

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

    ONE_TO_ONE_NAT

  • ✗

    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

A common pitfall is confusing disk `autoDelete` with network configuration. The public IP assignment is indicated by `type: ONE_TO_ONE_NAT` in the accessConfigs, not by `autoDelete`.

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

  • ONE_TO_ONE_NAT
  • accessConfigs

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

ONE_TO_ONE_NAT

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.

Visual reference

Inside (Private) PC-A 10.0.0.1 PC-B 10.0.0.2 NAT Router Outside (Public) 203.0.113.1 Inside Global Server PAT: many private IPs share one public IP via unique port numbers
