ACE Practice Question: A Cloud Run service needs to read secrets from…

This ACE practice question tests your understanding of a cloud run service needs to read secrets from…. 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 Cloud Run service needs to read secrets from Secret Manager. The service is deployed with a custom runtime service account. Which IAM role should be granted to the runtime service account, and on which resource?

A Cloud Run service needs to read secrets from Secret Manager. The service is deployed with a custom runtime service account. Which IAM role should be granted to the runtime service account, and on which resource?

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

Distractor review

Grant `roles/secretmanager.secretVersionManager` on the secret.

secretVersionManager manages secret versions (add, disable, destroy) but does not grant access to read the secret value (access is a separate permission).

B

Distractor review

Grant `roles/secretmanager.admin` on the project.

secretmanager.admin grants full management access to all secrets — far more than read access to a single secret. This violates least privilege.

C

Best answer

Grant `roles/secretmanager.secretAccessor` on the specific secret resource.

secretAccessor on the specific secret resource grants exactly the `secretmanager.versions.access` permission needed to read the secret value, scoped to that one secret only.

D

Distractor review

Grant `roles/viewer` on the project.

Project Viewer does not include `secretmanager.versions.access` — it grants read access to most resource metadata but not secret content.

Common exam trap

Common exam trap: authentication is not authorization

Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.

Technical deep dive

How to think about this question

This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.

KKey Concepts to Remember

  • Authentication checks who the user is.
  • Authorization controls what the user is allowed to do after login.
  • Privilege levels affect access to EXEC and configuration commands.
  • AAA, TACACS+ and RADIUS can separate login success from command access.

TExam Day Tips

  • Do not assume successful login means full administrative access.
  • Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
  • Separate login problems from permission problems before choosing the answer.

Key takeaway

Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

FAQ

Questions learners often ask

What does this ACE question test?

Authentication checks who the user is.

What is the correct answer to this question?

The correct answer is: Grant `roles/secretmanager.secretAccessor` on the specific secret resource. — To access a specific secret in Secret Manager, the identity needs `secretmanager.versions.access` permission (included in `roles/secretmanager.secretAccessor`). Granting this role on the specific secret resource (not the project) follows the principle of least privilege — the service account can only access that one secret, not all secrets in the project.

What should I do if I get this ACE question wrong?

Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related ACE questions on access control and AAA configuration.
