Linux Foundation Kubernetes and Cloud Native Security Associate Sample Questions (Q61-Q66):

NEW QUESTION # 61
What is the reasoning behind considering the Cloud as the trusted computing base of a Kubernetes cluster?

Answer: A

Explanation:
* The4C's of Cloud Native Security(Cloud, Cluster, Container, Code) model starts withCloudas the base layer.
* If the Cloud (infrastructure layer) is compromised, every higher layer (Cluster, Container, Code) inherits that compromise.
* Exact extract (Kubernetes Security Overview):
* "The 4C's of Cloud Native security are Cloud, Clusters, Containers, and Code. You can think of the 4C's as a layered approach. A Kubernetes cluster can only be as secure as the cloud infrastructure it is deployed on."
* This means the cloud is part of thetrusted computing baseof a Kubernetes cluster.

4cs-of-cloud-native-security


NEW QUESTION # 62
What is a multi-stage build?

Answer: A

Explanation:
* Multi-stage buildsare a Docker/Kaniko feature that allows building images in multiple stages # final image contains only runtime artifacts, not build tools.
* This reducesimage size, attack surface, and security risks.
* Exact extract (Docker Docs):
* "Multi-stage builds allow you to use multiple FROM statements in a Dockerfile. You can copy artifacts from one stage to another, resulting in smaller, optimized images."
* Clarifications:
* A: Collaboration is not the definition.
* B: Multiple repositories # multi-stage builds.
* C: Build concurrency # multi-stage builds.

NEW QUESTION # 63
An attacker has successfully overwhelmed the Kubernetes API server in a cluster with a single control plane node by flooding it with requests.
How would implementing a high-availability mode with multiple control plane nodes mitigate this attack?

Answer: D

Explanation:
* Inhigh-availability clusters, multiple API server instances run behind a load balancer.
* Thisdistributes client requests across multiple API servers, preventing a single API server from being overwhelmed.
* Exact extract (Kubernetes Docs - High Availability Clusters):
* "A highly available control plane runs multiple instances of kube-apiserver, typically fronted by a load balancer, so that if one instance fails or is overloaded, others continue serving requests."
* Other options clarified:
* A: Network segmentation does not directly mitigate API server DoS.
* C: Adding resources helps, but doesn't solve single-point-of-failure.
* D: Rate limiting is a valid mitigation but not provided by HA alone.

NEW QUESTION # 64
What is the purpose of an egress NetworkPolicy?

Answer: C

Explanation:
* NetworkPolicycontrols network trafficat the Pod level.
* Ingress rules:controlincomingconnections to Pods.
* Egress rules:controloutgoingconnectionsfrom Pods.
* Exact extract (Kubernetes Docs - Network Policies):
* "An egress rule controls outgoing connections from Pods that match the policy."
* Clarifying wrong answers:
* A/B: Too broad (cluster-level); policies apply per Pod/Namespace.
* C: Security against unauthorized access is broader than egress policies.
References:
Kubernetes Docs - Network Policies: https://kubernetes.io/docs/concepts/services-networking/network- policies/


NEW QUESTION # 65
Is it possible to restrict permissions so that a controller can only change the image of a deployment (without changing anything else about it, e.g., environment variables, commands, replicas, secrets)?

Answer: B

Explanation:
* RBAC in Kubernetesis coarse-grained: it controlsverbs(get, update, patch, delete) onresources(e.g., deployments), butnot individual fieldswithin a resource.
* There isno /image subresource for deployments(there is one for pods but only for ephemeral containers).
* Therefore,RBAC cannot restrict changes only to the image field.
* Admission Webhooks(mutating/validating)canenforce fine-grained policies (e.g., deny updates that change anything other than spec.containers[*].image).
* Exact extract (Kubernetes Docs - Admission Webhooks):
* "Admission webhooks can be used to enforce custom policies on objects being admitted." References:
Kubernetes Docs - RBAC: https://kubernetes.io/docs/reference/access-authn-authz/rbac/ Kubernetes Docs - Admission Webhooks: https://kubernetes.io/docs/reference/access-authn-authz
