Google ACE Deploying and Implementing a Cloud Solution Practice Question

This ACE practice question tests your understanding of deploying and implementing a cloud solution. 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.

A team is using Terraform to deploy infrastructure. They want to ensure that the Terraform state file is encrypted at rest using a customer-managed encryption key (CMEK). What should they configure?

A
Use a Cloud Storage bucket with CMEK enabled by default; no Terraform configuration needed
Correct. If the Cloud Storage bucket already has CMEK enabled by default, no further Terraform configuration is required for encryption; the bucket's default key handles encryption at rest.
B
Set the encryption block in the google_storage_bucket resource
Correct. When creating a bucket with Terraform, use the `encryption` block with a `default_kms_key_name` to specify a CMEK key. This ensures the bucket uses CMEK.
C
Set the kms_key argument in the google provider block
Why wrong: Incorrect. The `google` provider block does not have a `kms_key` argument for configuring storage encryption. Provider settings do not control per-resource encryption.
D
Set the kms_key argument in the terraform backend block
Why wrong: Incorrect. The `terraform` backend block for GCS does not accept a `kms_key` argument. The backend uses the bucket's default encryption settings.

Correct answer & explanation

✓

Use a Cloud Storage bucket with CMEK enabled by default; no Terraform configuration needed

To use CMEK with the GCS backend, you have two valid approaches: 1) Use an existing Cloud Storage bucket that already has CMEK enabled by default—no Terraform encryption configuration is needed because the bucket itself enforces encryption. 2) When creating a new bucket via the `google_storage_bucket` resource, set the `encryption` block with a `default_kms_key_name` to specify a CMEK key. The provider block does not have a `kms_key` argument, and the `terraform` backend block does not support a `kms_key` argument for GCS. Both options A and B are correct.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
