- A
Cloud Deployment Manager.
Why wrong: Cloud Deployment Manager is declarative but does not have the same level of modularity and state management as Terraform; it is a native Google tool but less flexible.
- B
Cloud Shell.
Why wrong: Cloud Shell is a browser-based shell environment, not an infrastructure-as-code tool.
- C
Terraform.
Correct. Terraform is a declarative IaC tool with modularity and state management.
- D
gcloud commands.
Why wrong: gcloud commands are imperative and not suitable for declarative infrastructure-as-code.

PCD Deploying applications Practice Question
This PCD practice question tests your understanding of deploying applications. 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 wants to deploy infrastructure as code on Google Cloud. They need a declarative language that supports modularity and state management. Which tool should they choose?
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
✓
Terraform.
Terraform is the correct choice because it is a declarative infrastructure-as-code tool that supports modularity through reusable modules and state management via state files (local or remote backends like Cloud Storage). It allows teams to define Google Cloud resources in HashiCorp Configuration Language (HCL) and track resource changes over time, enabling safe, incremental updates.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Cloud Deployment Manager.
Why it's wrong here
Cloud Deployment Manager is declarative but does not have the same level of modularity and state management as Terraform; it is a native Google tool but less flexible.
- ✗
Cloud Shell.
Why it's wrong here
Cloud Shell is a browser-based shell environment, not an infrastructure-as-code tool.
- ✓
Terraform.
Why this is correct
Correct. Terraform is a declarative IaC tool with modularity and state management.

- ✗
gcloud commands.
Why it's wrong here
gcloud commands are imperative and not suitable for declarative infrastructure-as-code.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Google often tests the distinction between declarative and imperative tools, and the trap here is that candidates may confuse Cloud Deployment Manager’s declarative templates with Terraform’s superior state management and modularity, or mistakenly think Cloud Shell or gcloud commands are suitable for infrastructure-as-code workflows.
Trap categories for this question
Command / output trap
gcloud commands are imperative and not suitable for declarative infrastructure-as-code.
Detailed technical explanation
How to think about this question
Terraform's state management uses a JSON state file that maps real-world resources to configuration, enabling Terraform to detect drift and plan incremental changes. Its provider plugin architecture (e.g., hashicorp/google) communicates with Google Cloud APIs via gRPC, and modules allow teams to encapsulate and version infrastructure patterns, which is critical for large-scale deployments with multiple environments. A subtle behavior is that Terraform's state can be locked using a backend like Cloud Storage with object versioning to prevent concurrent modifications, a feature not natively available in Cloud Deployment Manager.
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 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.
