PCDE Practice Question: Building and Implementing CI/CD Pipelines for a Service
This PCDE practice question tests your understanding of building and implementing ci/cd pipelines for a service. 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.
An organization wants to enforce security policies on container images before deployment. They need to scan images for vulnerabilities and ensure only images that pass the scan can be deployed. Which TWO services should they use? (Select TWO)
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
✓
Container Analysis
Container Analysis scans images for vulnerabilities. Binary Authorization enforces policies that require images to have attestations (e.g., from Container Analysis) before deployment.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Container Analysis
Why this is correct
Container Analysis provides vulnerability scanning.
Related concept
Authentication checks who the user is.
- ✗
Artifact Registry
Why it's wrong here
Artifact Registry stores images but does not enforce policies.
- ✗
Cloud Build
Why it's wrong here
Cloud Build builds images but does not enforce deployment policies.
- ✗
Cloud Deploy
Why it's wrong here
Cloud Deploy orchestrates deployments but does not enforce image scanning.
- ✓
Binary Authorization
Why this is correct
Binary Authorization enforces policy that only scanned images are deployed.
Related concept
Authentication checks who the user is.
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 PCDE questions on access control and AAA configuration.
