- A
Allow end users to download and use service account keys directly.
Why wrong: Service accounts are for applications, not individual users; using keys directly exposes them.
- B
Enable automatic key generation and disable any unused keys.
Automating key generation ensures uniqueness, and disabling unused keys reduces attack surface.
- C
Store the service account key in the application's source code for easy access.
Why wrong: Storing keys in source code is a security risk; they can be exposed in version control.
- D
Rotate service account keys regularly and store them in a secure secret management system.
Regular rotation limits the window of compromise, and secure storage protects the key.
- E
Use a single service account key for all environments to simplify management.
Why wrong: Using the same key across environments increases risk if one environment is compromised.
PCSE Practice Question: Configuring access within a cloud solution environment
This PCSE practice question tests your understanding of configuring access within a cloud solution environment. 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 company wants to use service account keys for an on-premises application that needs to authenticate to Google Cloud APIs. Which two practices should they follow to minimize security risks? (Choose TWO.)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"minimum / minimize"Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
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
Enable automatic key generation and disable any unused keys.
Option B is correct because enabling automatic key generation ensures that keys are created with strong cryptographic standards and that unused keys are promptly disabled, reducing the attack surface. This practice aligns with Google Cloud's recommendation to minimize the number of active keys and to avoid manual key management errors.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Allow end users to download and use service account keys directly.
Why it's wrong here
Service accounts are for applications, not individual users; using keys directly exposes them.
- ✓
Enable automatic key generation and disable any unused keys.
Why this is correct
Automating key generation ensures uniqueness, and disabling unused keys reduces attack surface.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the misconception that storing keys in source code is acceptable for convenience, or that a single key across environments simplifies management, when in fact both practices drastically increase security risk.
Detailed technical explanation
How to think about this question
Service account keys are RSA private keys used to sign JSON Web Tokens (JWTs) for OAuth 2.0 client assertions. Google Cloud recommends using a dedicated secret management system like Secret Manager or HashiCorp Vault to store keys, with automatic rotation policies (e.g., every 90 days) to limit the window of exposure. In practice, a compromised key can be used to generate access tokens for any API the service account is authorized for, making key hygiene critical.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
