Full question →mediummultiple choiceObjective-mapped
A DevOps team builds container images in a CI/CD pipeline. Security wants to reduce the chance of deploying vulnerable libraries and also wants the cluster to reject images that have not been approved. Which approach best meets both requirements?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Increase CPU and memory limits for the containers so they run more safely.
Resource limits can improve stability, but they do not address vulnerable dependencies or image trust. This is a performance control, not an image security control.
B
Distractor review
Allow developers to pull images from any registry as long as the tags look familiar.
Tags are easy to copy or spoof and do not prove an image was approved. This creates supply-chain risk rather than reducing it.
C
Distractor review
Disable pipeline scanning to speed releases and rely on runtime monitoring after deployment.
Runtime monitoring is useful, but it reacts after deployment. Disabling build-time checks increases the chance that a risky image reaches production.
D
Best answer
Scan images in the pipeline and enforce signature verification or admission control before deployment.
Build-time scanning helps identify vulnerable packages before release, while signature verification or admission control ensures only approved images can run in the cluster. Together, these controls reduce both content risk and deployment risk. This is the strongest combined answer because it addresses prevention and policy enforcement.
Common exam trap
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.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this SY0-701 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Scan images in the pipeline and enforce signature verification or admission control before deployment. — The best solution combines image scanning with enforcement controls. Scanning in the pipeline helps catch outdated or vulnerable packages before an image is published. Signature verification and admission control add trust by ensuring the runtime platform only accepts images that were approved by the organization. That combination maps well to container and cloud-native security goals because it protects both the supply chain and the deployment environment. Why others are wrong: Option A is about performance tuning, not security assurance. Option B trusts image tags, which are not a reliable security boundary. Option C relies on detection after deployment and skips the preventive controls that would stop risky images from reaching the cluster in the first place.
