The correct answer is to scan the image and rebuild it from an approved base image. This works because container image vulnerability scanning before deployment identifies known Common Vulnerabilities and Exposures (CVEs) in libraries and packages, while rebuilding from a hardened base image replaces those risky components with patched, trusted versions. On the Security+ SY0-701 exam, this tests your understanding of secure software development and deployment controls within Domain 3 (Implementation), often presented as a scenario where a team must choose between scanning alone versus scanning plus rebuilding. A common trap is thinking that simply scanning and alerting is sufficient—but the exam emphasizes that scanning without remediation leaves vulnerabilities in place. Memory tip: “Scan and rebuild, don’t just peek—patch the weak.”
SY0-701 Security Architecture Practice Question
This SY0-701 practice question tests your understanding of security architecture. 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 development team stores container images in a registry before deployment. Security wants to reduce the chance of shipping vulnerable libraries or packages inside the image. What should the team do before release?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Scan the image and rebuild it from an approved base image.
Scanning the image for known vulnerabilities (CVEs) and rebuilding it from an approved, hardened base image ensures that only trusted, patched libraries and packages are included. This directly reduces the attack surface by eliminating vulnerable components before the image is deployed to production.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Run the container as root so startup problems are less likely.
Why it's wrong here
Running as root increases risk and does not address vulnerable content inside the image.
✓
Scan the image and rebuild it from an approved base image.
Why this is correct
Scanning and using approved base images helps catch vulnerable packages before deployment.
Related concept
Read the scenario before looking for a memorised answer.
✗
Open the container port on the host firewall so the image can be reached faster.
Why it's wrong here
Firewall changes affect traffic flow, but they do not remove insecure dependencies from the image.
✗
Add more CPU and memory to the cluster to improve image security.
Why it's wrong here
Extra resources may improve performance, but they do nothing to reduce software risk in the image.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse operational practices (like running as root or opening ports) with security controls that directly address software supply chain risks, or mistakenly think that adding resources can compensate for insecure image content.
Detailed technical explanation
How to think about this question
Container image scanning tools (e.g., Trivy, Clair, or Snyk) compare the software bill of materials (SBOM) of the image against public CVE databases. Rebuilding from an approved base image (e.g., distroless or a minimal Alpine variant) eliminates unnecessary packages and reduces the attack surface, as these base images are maintained with security patches by their vendors.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A DevOps team stores container images in a registry before deployment. Which two practices reduce the chance of deploying a risky image? Select two.
easy
✓ A.Scan images for known vulnerabilities before they are promoted to production.
✓ B.Use trusted minimal base images and remove unnecessary packages.
C.Run containers as root by default to simplify troubleshooting.
D.Mount the host operating system filesystem into every container.
E.Deploy images using the latest tag without reviewing version history.
Why A: Option A is correct because scanning container images for known vulnerabilities (e.g., using tools like Trivy or Clair) identifies CVEs in the OS packages or application dependencies before the image reaches production. This proactive check prevents deploying images with exploitable flaws, aligning with secure software supply chain practices. Option B is correct because using trusted minimal base images (e.g., Alpine or distroless) reduces the attack surface, and removing unnecessary packages eliminates potential vulnerabilities from unused components, following the principle of least functionality.
