- A
Deny All
Why wrong: This blocks all images, including the trusted ones.
- B
Allow All
Why wrong: This allows all images, including unsigned ones, which defeats the purpose.
- C
Require Attestation
This policy requires attestation for all images except those explicitly exempted via a breakglass or exception rule.
- D
Allow by Registry
Why wrong: This is not a valid Binary Authorization policy type.

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 uses Binary Authorization to enforce that only images signed by an approved attestor are deployed in GKE. They want to allow a specific set of images from a trusted registry to bypass the policy. Which Binary Authorization policy type should they use?
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
✓
Require Attestation
Binary Authorization supports policy types like 'Require Attestation', 'Allow All', and 'Deny All'. To allow specific images while requiring attestation for others, they would use 'Require Attestation' with an exception list. There is no 'Allow by Registry' built-in type.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Deny All
Why it's wrong here
This blocks all images, including the trusted ones.
- ✗
Allow All
Why it's wrong here
This allows all images, including unsigned ones, which defeats the purpose.
- ✓
Require Attestation
Why this is correct
This policy requires attestation for all images except those explicitly exempted via a breakglass or exception rule.
Related concept
Authentication checks who the user is.
- ✗
Allow by Registry
Why it's wrong here
This is not a valid Binary Authorization policy type.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
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.
