This CCSP practice question tests your understanding of cloud application security. 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.
A healthcare SaaS company runs containerized microservices on Google Kubernetes Engine (GKE). The security team scans containers with a vulnerability scanner and finds that base images have several critical vulnerabilities. The container build process uses a Dockerfile that pulls the latest Ubuntu image from Docker Hub. The team wants to reduce the attack surface without delaying feature releases. What is the best approach?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Adopt minimal hardened base images and integrate vulnerability scanning into CI/CD
Option D is correct because using minimal hardened images (e.g., distroless) reduces vulnerabilities and attack surface. Option A (weekly patching) leaves windows open. Option B (rebuild from scratch) is time-consuming and error-prone. Option C (network segmentation) does not address vulnerable images.
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.
✗
Place a network security policy to restrict outbound traffic from pods
Why it's wrong here
Network controls do not fix vulnerable images inside the container.
✗
Schedule weekly automated rebuilds with the latest base image
Why it's wrong here
Weekly rebuilds are insufficient; threats emerge quickly.
✓
Adopt minimal hardened base images and integrate vulnerability scanning into CI/CD
Why this is correct
Hardened images minimize vulnerabilities and scanning ensures early detection.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
Refactor all applications to use scratch as base image
Why it's wrong here
Rebuilding from scratch introduces custom complexity and maintenance overhead.
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 security team runs a vulnerability scan on a web application and discovers an unpatched SQL injection flaw. The team prioritises remediation by CVSS score — critical flaws are patched within 24 hours, high within 7 days. Questions like this test whether you understand vulnerability management processes, scanning tools, and remediation prioritisation.
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 CCSP NAT questions on configuration and troubleshooting.

What is the correct answer to this question?
The correct answer is: Adopt minimal hardened base images and integrate vulnerability scanning into CI/CD — Option D is correct because using minimal hardened images (e.g., distroless) reduces vulnerabilities and attack surface. Option A (weekly patching) leaves windows open. Option B (rebuild from scratch) is time-consuming and error-prone. Option C (network segmentation) does not address vulnerable images.

Are there clue words in this question I should notice?
Yes — watch for: "best". Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
