Question 1:
Which attack technique can be detected by monitoring privileged Pod creations?
B. Data exfiltration via DNS tunneling
C. Brute-force login attempts
D. Man-in-the-middle attacks on the API server
E. Kernel exploitation attempts
Answer: D
Explanation:
Attackers may deploy privileged Pods to exploit kernel vulnerabilities and gain full control over cluster nodes.
Question 2:
What should you do to minimize the risk of privilege escalation in RBAC?
A. Avoid granting wildcard permissions in roles
B. Use RoleBindings with service accounts exclusively
C. Assign multiple ClusterRoles to each user
D. Disable RBAC completely
Answer: A
Explanation:
Avoiding wildcard permissions in roles prevents users or applications from gaining unintended access to resources, reducing the risk of privilege escalation.
Question 3:
Which seccomp profile action generates a SIGSYS signal upon a blocked system call?
A. Audit
B. Errno
C. Kill
D. Trap
Answer: D
Explanation:
The trap action in a seccomp profile triggers a SIGSYS signal, allowing custom handlers to address the violation.
Question 4:
What is the main reason for using lightweight container images in production environments?
A. Reduces the number of potential vulnerabilities in images
B. Enables faster pulling of images by the container runtime
C. Simplifies namespace configuration in Kubernetes clusters
D. Improves scheduling efficiency across node pools
Answer: A
Explanation:
Lightweight images minimize unnecessary dependencies, reducing the surface area for vulnerabilities and improving security.
Question 5:
Which feature is used to implement granular access control for specific Kubernetes API operations?
A. kube-scheduler affinity rules
B. NodeRestriction admission plugin
C. Role-Based Access Control (RBAC)
D. PodSecurityPolicy
Answer: C
Explanation:
RBAC provides fine-grained access control, allowing administrators to define permissions for specific users, groups, or service accounts, ensuring secure API operations.

Question 6:
Why should static analysis warn against using wildcard patterns (*) in Kubernetes Role definitions?
A. Increases pod scheduling delays
B. Creates overly broad permissions
C. Reduces compatibility with Kubernetes API groups
D. Conflicts with namespace-scoped resource quotas
Answer: B
Explanation:
Using wildcards in Role definitions grants unnecessary access to resources, violating the principle of least privilege and increasing the risk of compromise.
Question 7:
How can you verify that a new kubelet version is running after an upgrade?
A. kubeadm version
B. kubectl get nodes -o wide
C. kubectl describe kubelet
D. kubelet --version
Answer: D
Explanation:
Running kubelet –version on a node confirms the version of the kubelet binary, ensuring that the upgrade was applied successfully.
Question 8:
Which Kubernetes object allows you to configure granular RBAC rules for accessing the Dashboard?
A. RoleBinding
B. PodSecurityPolicy
C. CustomResourceDefinition
D. NetworkPolicy
Answer: A
Explanation:
RoleBindings enable granular RBAC rules, allowing precise control over which users or groups can access the Kubernetes Dashboard.
Question 9:
What is the main purpose of the Kata Containers runtime in multi-tenant Kubernetes environments?
A. To reduce disk usage on the host
B. To provide strong isolation between workloads
C. To increase container network performance
D. To simplify the management of Secrets
Answer: B
Explanation:
Kata Containers run each container inside a lightweight virtual machine, ensuring robust isolation between tenants and minimizing the risk of lateral attacks.
Question 10:
Which approach reduces the attack surface of the underlying host in a Kubernetes environment?
A. Allowing all containers to access the host network.
B. Running container workloads with the highest available privileges.
C. Using a minimal host operating system without unnecessary services.
D. Sharing /etc/hosts between containers and the host.
Answer: C
Explanation:
Using a minimal host operating system with only essential services reduces the attack surface by limiting potential entry points for attackers and minimizing unnecessary system complexity.
