Google ACE Practice Question: Ensuring successful operation of a cloud solution

This ACE practice question tests your understanding of ensuring successful operation of 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 is using Terraform to manage infrastructure in Google Cloud. After running terraform apply, they receive an error: 'Error 409: Resource already exists'. The team needs to resolve this without deleting and recreating the resource. What should they do?

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

Import the existing resource into Terraform state with 'terraform import'.

Option B is correct because the 'Error 409: Resource already exists' indicates that the resource was created outside of Terraform or the state file lost track of it. Running 'terraform import' brings the existing resource under Terraform management by adding its current attributes to the state file, allowing subsequent operations without deletion or recreation.

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.

  • Run 'terraform refresh' to update the state file.

    Why it's wrong here

    Refresh updates existing state but does not import unmanaged resources.

  • Import the existing resource into Terraform state with 'terraform import'.

    Why this is correct

    Importing tells Terraform to adopt the existing resource into its state.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Set the 'create_before_destroy' lifecycle rule on the resource.

    Why it's wrong here

    This affects update behavior, not import.

  • Change the resource name in the Terraform configuration.

    Why it's wrong here

    Changing the name would create a new resource, not adopt the existing one.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Google Cloud often tests the misconception that 'terraform refresh' can fix state mismatches for missing resources, but it only syncs attributes for resources already in state, not imports new ones.

Detailed technical explanation

How to think about this question

Under the hood, Terraform's state file is a JSON mapping of resource addresses to their unique identifiers (e.g., Google Cloud resource IDs). When a resource exists in GCP but not in state, 'terraform import' performs a read-only API call to fetch the resource's attributes and writes them into the state file, associating the resource with the given configuration address. This is critical in real-world scenarios where resources are created via the console, CLI, or by another team, and must be brought under IaC control without downtime.

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 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.
