What is a key security advantage of using gVisor as a container runtime?

It eliminates the need for seccomp and other security features

It provides an additional layer of isolation by intercepting system calls

It automatically scans images for vulnerabilities

It is faster than other runtimes because it uses the host kernel directly

A security operations team needs to detect container escape attempts in real time. They have limited resources and cannot deploy a full SIEM. Which approach provides real-time detection with minimal overhead?

Collect container logs with Fluentd

Use Prometheus to monitor system calls

Enable Kubernetes audit logging

Deploy Falco with a focused rule set

A security team is concerned about container runtime vulnerabilities that could allow a container to access the host's filesystem. Which mitigation strategy is most effective?

Use a runtime with user-space kernel isolation like gVisor

Container Runtime KCSA Practice Questions (Page 6)

Part of the Kubernetes Cluster Component Security domain, which accounts for 22% of the KCSA exam. Linux Foundation does not publish an official question count, but from its 90-minute exam (~35–60 total, ~8–13 in this domain), expect 1–2 from this objective — we provide 33 practice questions to prepare you well beyond it.
