Linux Foundation KCSA Exam Syllabus Topics:

Topic	Details
Topic 1	Kubernetes Security Fundamentals: This section of the exam measures the skills of a Kubernetes Administrator and covers the primary security mechanisms within Kubernetes. This includes implementing pod security standards and admissions, configuring robust authentication and authorization systems like RBAC, managing secrets properly, and using network policies and audit logging to enforce isolation and monitor cluster activity.
Topic 2	Kubernetes Threat Model: This section of the exam measures the skills of a Cloud Security Architect and involves identifying and mitigating potential threats to a Kubernetes cluster. It requires understanding common attack vectors like privilege escalation, denial of service, malicious code execution, and network-based attacks, as well as strategies to protect sensitive data and prevent an attacker from gaining persistence within the environment.
Topic 3	Overview of Cloud Native Security: This section of the exam measures the skills of a Cloud Security Architect and covers the foundational security principles of cloud-native environments. It includes an understanding of the 4Cs security model, the shared responsibility model for cloud infrastructure, common security controls and compliance frameworks, and techniques for isolating resources and securing artifacts like container images and application code.
Topic 4	Kubernetes Cluster Component Security: This section of the exam measures the skills of a Kubernetes Administrator and focuses on securing the core components that make up a Kubernetes cluster. It encompasses the security configuration and potential vulnerabilities of essential parts such as the API server, etcd, kubelet, container runtime, and networking elements, ensuring each component is hardened against attacks.

Linux Foundation Kubernetes and Cloud Native Security Associate Sample Questions (Q56-Q61):

NEW QUESTION # 56
What does thecluster-adminClusterRole enable when used in a RoleBinding?

A. It allows read/write access to most resources in the role binding's namespace. This role does not allow write access to resource quota, to the namespace itself, and to EndpointSlices (or Endpoints).
B. It gives full control over every resource in the role binding's namespace, including the namespace itself.
C. It gives full control over every resource in the role binding's namespace, not including the namespace object for isolation purposes.
D. It gives full control over every resource in the cluster and in all namespaces.

Answer: D

Explanation:
* Thecluster-adminClusterRole is asuperuser rolein Kubernetes.
* Binding it (via RoleBinding or ClusterRoleBinding) grantsunrestricted control over all resources in the cluster, across all namespaces.
* This includes management of cluster-scoped resources (nodes, CRDs, RBAC rules) and namespace- scoped resources.
* Therefore, cluster-admin is equivalent toroot-level accessin Kubernetes and must be used with extreme caution.

Kubernetes Documentation - Default Roles and Role Bindings
CNCF Security Whitepaper - Identity and Access Management: cautions against assigningcluster-admin broadly due to its unrestricted nature.

NEW QUESTION # 57
Which of the following statements correctly describes a container breakout?

A. A container breakout is the process of escaping the container and gaining access to the cloud provider's infrastructure.
B. A container breakout is the process of escaping a container when it reaches its resource limits.
C. A container breakout is the process of escaping the container and gaining access to the Pod's network traffic.
D. A container breakout is the process of escaping the container and gaining access to the host operating system.

Answer: D

Explanation:
* Container breakoutrefers to an attacker escaping container isolation and reaching thehost OS.
* Once the host is compromised, the attacker can accessother containers, Kubernetes nodes, or escalate further.
* Exact extract (Kubernetes Security Docs):
* "If an attacker gains access to a container, they may attempt a container breakout to gain access to the host system."
* Other options clarified:
* A: Network access inside a Pod # breakout.
* B: Resource exhaustion is aDoS, not a breakout.
* C: Cloud infrastructure compromise is possibleafterhost compromise, but not the definition of breakout.

NEW QUESTION # 58
What kind of organization would need to be compliant with PCI DSS?

A. Retail stores that only accept cash payments.
B. Non-profit organizations that handle sensitive customer data.
C. Merchants that process credit card payments.
D. Government agencies that collect personally identifiable information.

Answer: C

Explanation:
* PCI DSS (Payment Card Industry Data Security Standard):applies to any entity thatstores, processes, or transmits cardholder data.
* Exact extract (PCI DSS official summary):
* "PCI DSS applies to all entities that store, process or transmit cardholder data (CHD) and
/or sensitive authentication data (SAD)."
* Therefore,merchants who process credit card paymentsmust comply.
* Why others are wrong:
* A: No card payments, so no PCI scope.
* B: This falls underFISMA / NIST 800-53, not PCI DSS.
* C: Non-profits may handle sensitive data, but PCI only applies if they processcredit cards.

NEW QUESTION # 59
When should soft multitenancy be used over hard multitenancy?

A. When the priority is enabling resource sharing and efficiency between tenants.
B. When the priority is enabling complete isolation between tenants.
C. When the priority is enabling strict security boundaries between tenants.
D. When the priority is enabling fine-grained control over tenant resources.

Answer: A

Explanation:
* Soft multitenancy(Namespaces, RBAC, Network Policies) # assumes some level of trust between tenants, focuses onresource sharing and efficiency.
* Hard multitenancy(separate clusters or strong virtualization) # strict isolation, used when tenants are untrusted.
* Exact extract (CNCF TAG Security Multi-Tenancy Whitepaper):
* "Soft multi-tenancy refers to multiple workloads running in the same cluster with some trust assumptions. It provides resource sharing and operational efficiency. Hard multi- tenancy requires stronger isolation guarantees, typically separate clusters." References:
CNCF Security TAG - Multi-Tenancy Whitepaper:https://github.com/cncf/tag-security/tree/main/multi- tenancy

NEW QUESTION # 60
In a cluster that contains Nodes withmultiple container runtimesinstalled, how can a Pod be configured to be created on a specific runtime?

A. By using a command-line flag when creating the Pod.
B. By specifying the container runtime in the Pod's YAML file.
C. By modifying the Docker daemon configuration.
D. By setting the container runtime as an environment variable in the Pod.

Answer: B

Explanation:
* Kubernetes supportsmultiple container runtimeson a node via theRuntimeClassresource.
* To select a runtime, you specify the runtimeClassName field in thePod's YAML manifest. Example:
* apiVersion: v1
* kind: Pod
* metadata:
* name: example
* spec:
* runtimeClassName: gvisor
* containers:
* - name: app
* image: nginx
* Incorrect options:
* (A) You cannot specify container runtime through a kubectl command-line flag.
* (B) Modifying the Docker daemon config does not direct Kubernetes Pods to a runtime.
* (C) Environment variables inside a Pod spec do not control container runtimes.
