GCDL Practice Question: 'infrastructure as code' (IaC), and what problem…
This GCDL practice question tests your understanding of 'infrastructure as code' (iac), and what problem…. 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.
What is 'infrastructure as code' (IaC), and what problem does it solve compared to manually configuring cloud resources through a web console?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
IaC defines infrastructure in version-controlled code files, enabling reproducible, automated, and consistent environment provisioning versus error-prone manual console configuration.
IaC makes infrastructure reproducible (apply the same code to get the same result), version-controlled (track changes like software), automated (CI/CD pipelines), and consistent (no manual variation).
B
Distractor review
IaC is a tool that automatically discovers and documents existing cloud infrastructure.
IaC prescriptively defines what infrastructure should exist. Cloud Asset Inventory or other discovery tools describe what currently exists. They are different capabilities.
C
Distractor review
IaC requires writing custom Python scripts for every cloud resource type.
IaC tools like Terraform use declarative configuration languages (HCL) where you describe the desired state, not procedural scripts. No custom Python is required for standard resources.
D
Distractor review
IaC is a programming language specifically for writing cloud applications.
IaC is not a programming language for applications. It's a practice of defining infrastructure configuration in code files (using tools like Terraform HCL or YAML) for repeatable, automated provisioning.
Common exam trap
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.
Technical deep dive
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.

Question 1
A traditional retailer currently maintains its own data centers, purchasing servers every 3–5 years and paying for facilities, power, and staff regardless of demand. When it migrates its workloads to the public cloud, which change in cost model does it experience?
Question 2
An e-commerce company plans its infrastructure for peak shopping events (e.g., Black Friday) which drive 50× normal traffic. On-premises, they must maintain 50× capacity year-round. In the cloud, they provision 50× capacity only during peak periods. Which cloud characteristic enables this cost optimization?

Question 4
When a company moves from maintaining its own data center to using Google Cloud, which operational responsibility does Google assume that the company previously managed?
Question 5
A hospital runs a patient records system that must remain on-premises due to strict regulatory data residency requirements. However, they also want to use cloud-based AI for diagnostic imaging analysis. Which cloud deployment model best describes their architecture?

FAQ
Questions learners often ask
What does this GCDL question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: IaC defines infrastructure in version-controlled code files, enabling reproducible, automated, and consistent environment provisioning versus error-prone manual console configuration. — Infrastructure as Code (IaC) defines cloud infrastructure (VMs, networks, databases, IAM policies) in text files (code) using tools like Terraform or Google Cloud Deployment Manager. This solves several problems with manual console provisioning: reproducibility (same code = same infrastructure every time), version control (track changes in Git), automation (deploy via CI/CD), documentation (the code IS the documentation), and consistency (no human configuration errors between environments).
What should I do if I get this GCDL question wrong?
Identify which GCDL exam domain this question belongs to, then review the specific concept being tested. Practise related questions in that domain and focus on understanding why each wrong answer is tempting — not just why the correct answer is right.
