- A
Store the private key in a GCS bucket with uniform bucket-level access.
Why wrong: GCS is not designed for key storage; it lacks key rotation and audit features.
- B
Store the private key in Secret Manager.
Why wrong: Secret Manager is for secrets, but for signing keys, Cloud KMS is the appropriate service.
- C
Store the private key in Cloud Key Management Service (Cloud KMS).
Cloud KMS is the secure and managed way to store keys for Binary Authorization.
- D
Store the private key on the developer's workstation.
Why wrong: This is not secure and does not meet enterprise security requirements.

PCSE Practice Question: Managing Operations in a Cloud Solution Environment
This PCSE practice question tests your understanding of managing operations in a cloud solution environment. 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.
An organization wants to enforce that all container images deployed to a GKE cluster must be signed by an approved authority. They have set up Binary Authorization with a policy that requires attestation. Where should the signing key be stored to meet security best practices?

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
✓
Store the private key in Cloud Key Management Service (Cloud KMS).
Binary Authorization integrates with Cloud Key Management Service (KMS) to store attestor keys. Cloud KMS provides centralized key management, access control via IAM, and audit logging. Using a key stored in Cloud KMS is the recommended approach.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

Common exam traps
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.
Detailed technical explanation
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.
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 Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related PCSE questions on access control and AAA configuration.
