PCDOE Building and implementing CI/CD pipelines Practice Question
This PCDOE practice question tests your understanding of building and implementing ci/cd pipelines. 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.
What security checks can be integrated into a Cloud Build CI/CD pipeline? (Select TWO)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Container scanning with Artifact Analysis
Options A and B are correct. Container scanning with Artifact Analysis (A) is native. SAST can be added via custom steps (B). Option C (network penetration) is external. Option D (manual code review) is a process, not a tool. Option E (DAST) is for running apps.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Manual code review
Why it's wrong here
Manual review is a process, not an automated security check in the pipeline.
✓
Container scanning with Artifact Analysis
Why this is correct
Artifact Analysis can scan container images for vulnerabilities as part of the pipeline.
Related concept
Static NAT maps one inside address to one outside address.
✗
Network penetration testing
Why it's wrong here
Penetration testing is typically external and not integrated into CI/CD pipelines.
✗
Dynamic application security testing (DAST)
Why it's wrong here
DAST requires a running application, which is not typically part of a build pipeline.
✓
Static application security testing (SAST) with Cloud Build custom steps
Why this is correct
SAST tools can be run as custom build steps (e.g., using a container with a SAST tool).
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PCDOE NAT questions on configuration and troubleshooting.
