PCDOE Practice Question: Bootstrapping a Google Cloud organization for DevOps
This PCDOE practice question tests your understanding of bootstrapping a google cloud organization for devops. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 DevOps team is bootstrapping their Google Cloud organization and wants to enable Infrastructure as Code (IaC) using Terraform. They need a service account that Terraform can use to create and manage resources across multiple projects. What is the best practice for creating and managing this service account?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a service account in a separate 'admin' project and grant it the required roles on each project via IAM.
Option A is correct because creating a service account in a dedicated 'admin' project and granting it necessary roles across projects is a common pattern. Option B is wrong because the default service account has too many permissions and is not recommended. Option C is wrong because service account keys should be avoided in source control. Option D is wrong because using a user account is not secure for automation.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Create a service account in a separate 'admin' project and grant it the required roles on each project via IAM.
Why this is correct
This provides centralized control and separates credentials from workloads.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
Generate a service account key and store it in a Cloud Storage bucket accessible to the team.
Why it's wrong here
Keys should be managed securely, not stored in a bucket accessible to many.
✗
Use a user account with two-factor authentication for Terraform automation.
Why it's wrong here
User accounts are for humans, not automated systems; service accounts are for automation.
✗
Use the Compute Engine default service account from the project where Terraform runs.
Why it's wrong here
Default SAs have excessive permissions and can't be scoped easily across projects.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PCDOE NAT questions on configuration and troubleshooting.
